To identify spatiotemporal gait parameters and plantar pressure distribution during barefoot walking in people with gout and people with asymptomatic hyperuricemia by comparing them to healthy individuals with normal serum urate concentrations. Eighty-seven participants were included: 24 with gout, 29 with asymptomatic hyperuricemia and 34 age- and sex-matched normouricemic control participants. Spatiotemporal parameters of gait were assessed during level barefoot walking using a GAITRite® walkway. Peak plantar pressure and pressure time integrals were recorded using a TekScan MatScan®. Results were adjusted for age and body mass index. Compared to normouricemic control participants, participants with gout demonstrated increased step time (P = 0.022) and stance time (P = 0.022), and reduced velocity (P = 0.050). Participants with gout also walked with decreased peak pressure at the heel (P = 0.012) and hallux (P = 0.036) and increased peak pressure (P | 0.001) and pressure time integrals (P = 0.005)
The use of inertial sensors to characterize pathological gait has traditionally been based on the calculation of temporal and spatial gait variables from inertial sensor data. This approach has proved successful in the identification of gait deviations in populations where substantial differences from normal gait patterns exist; such as in Parkinsonian gait. However, it is not currently clear if this approach could identify more subtle gait deviations, such as those associated with musculoskeletal injury. This study investigates whether additional analysis of inertial sensor data, based on quantification of gyroscope features of interest, would provide further discriminant capability in this regard. The tested cohort consisted of a group of anterior cruciate ligament reconstructed (ACL-R) females and a group of non-injured female controls, each performed ten walking trials. Gait performance was measured simultaneously using inertial sensors and an optoelectronic marker based system. The ACL-R group
The purpose of this study was to investigate the asymmetry of anticipatory postural adjustment (APA) during gait initiation and to determine whether the process of choosing the initial swing leg affects APA during gait initiation. The participants initiated gait with the leg indicated by a start tone or initiated gait with the leg spontaneously chosen. The dependent variables of APA were not significantly different among the condition of initiating gait with the preferred leg indicated by the start tone, the condition of initiating gait with the non-preferred leg indicated by the start tone, and the condition of initiating gait with the leg spontaneously chosen. These findings fail to support the view that the process of choosing the initial swing leg affects APA during gait initiation. The lateral displacement of the center of pressure in the period in which shifting the center of pressure to the initial swing phase before initiating gait with the left leg indicated by the external cue was ...
TY - JOUR. T1 - Gait mechanics differences between healthy controls and patients with peripheral artery disease after adjusting for gait velocity, stride length, and step width. AU - McCamley, John D.. AU - Cutler, Eric L.. AU - Schmid, Kendra K. AU - Wurdeman, Shane R.. AU - Johanning, Jason M. AU - Pipinos, Iraklis I. AU - Myers, Sara A. PY - 2019/2. Y1 - 2019/2. N2 - Patients with peripheral artery disease (PAD) experience significant leg dysfunction. The effects of PAD on gait include shortened steps, slower walking velocity, and altered gait kinematics and kinetics, which may confound joint torques and power measurements. Spatiotemporal parameters and joint torques and powers were calculated and compared between 20 patients with PAD and 20 healthy controls using independent t tests. Separate analysis of covariance models were used to evaluate group differences after independently adjusting for gait velocity, stride length, and step width. Compared with healthy controls, patients with PAD ...
BACKGROUND: Multiple aspects of gait are typically impaired post-stroke. Asymmetric gait is common as a consequence of unilateral brain lesions. The relationship between the resulting asymmetric gait and impairments in the ability to properly coordinate the reciprocal stepping activation of the legs is not clear. The objective of this exploratory study is to quantify the effects of hemiparesis on two putatively independent aspects of the bilateral coordination of gait to gain insight into mechanisms and their relationship and to assess their potential as clinical markers. METHODS: Twelve ambulatory stroke patients and age-matched healthy adults wore a tri-axial piezo-resistive accelerometer and walked back and forth along a straight path in a hall at a comfortable walking speed during 2 minutes. Gait speed, gait asymmetry (GA), and aspects of the bilateral coordination of gait (BCG) were determined. Bilateral coordination measures included the left-right stepping phase for each stride phii, ...
BACKGROUND/AIM: Three-dimensional kinematic measures of gait are routinely used in clinical gait analysis and provide a key outcome measure for gait research and clinical practice. This systematic review identifies and evaluates current evidence for the inter-session and inter-assessor reliability of three-dimensional kinematic gait analysis (3DGA) data. METHOD: A targeted search strategy identified reports that fulfilled the search criteria. The quality of full-text reports were tabulated and evaluated for quality using a customised critical appraisal tool. RESULTS: Fifteen full manuscripts and eight abstracts were included. Studies addressed both within-assessor and between-assessor reliability, with most examining healthy adults. Four full-text reports evaluated reliability in people with gait pathologies. The highest reliability indices occurred in the hip and knee in the sagittal plane, with lowest errors in pelvic rotation and obliquity and hip abduction. Lowest reliability and highest ...
Three-dimensional gait analysis has a long tradition as a diagnostic tool in pediatric orthopedics, especially in the treatment of cerebral palsy. Furthermore, it is established as an objective tool to report and monitor outcomes of interventions. However, despite three-dimensional gait analysis is effective in refining indications and dosage of interventions and in further understanding different gait pathologies to optimize treatment recommendations, many clinicians still ignore these findings and rely only on findings of clinical and radiographic evaluation.. In my lecture, I will focus on advances in patient treatment as a result of using gait analysis. Furthermore, I will discuss lessons we have learned from outcome evaluations using gait analysis and resulting changes in strategies of treatment. Another part of this talk will emphasize strategies to encourage clinicians to use gait analysis data to optimize their results and as a way to standardize indications and treatment ...
Variability raises considerable interest as a promising and sensitive marker of dysfunction in physiology, in particular in neurosciences. Both internally (e.g. pathology) and/or externally (e.g. environment) generated perturbations and the neuro-mechanical responses to them contribute to the fluctuating dynamics of locomotion. Defective internal gait control in Parkinsons disease (PD), resulting in typical timing gait disorders, is characterized by the breakdown of the temporal organization of stride duration variability. Influence of external cue on gait pattern could be detrimental or advantageous depending on situations (healthy or pathological gait pattern, respectively). As well as being an interesting rehabilitative approach in PD, treadmills are usually implemented in laboratory settings to perform instrumented gait analysis including gait variability assessment. However, possibly acting as an external pacemaker, treadmill could modulate the temporal organization of gait variability of PD
Human manner of walking characterized by kinematic parameters measure posture-gait control characterizing the dynamic changes in body parts with the involvement of multi-sensory patterns processed by different parts of the brain. In this study, low-cost sensors have been used to collect gait signals and identify the features responsible for differentiating the gait phases (swing/stance). Dataset was obtained for a total of 160 trails with 5 gait cycles per trail from healthy volunteers (n=20). Torque involved during progressive gait was also estimated to model regulation of the body for maintaining balance in gait and posture. Additionally, we also investigated EEG and gait correlates by identifying the brain regions that are active during movement initiation and during stance and swing (a progressive gait) using electroencephalography. While identifying key biomarkers relevant for posture control and gait, this could enhance low-cost detection of movement related diseases in technically ...
Mean gait velocity under single (sGV) and dual tasks (vGV, cGV). Note: sGV: single task gait velocity; vGV: verbal gait velocity; cGV: counting gait velocity.
Your doctor will likely encourage you to start gait training as soon as possible after an injury or illness that affects your ability to walk. They may recommend other forms of physical therapy and treatments too. You must be healthy enough for physical activity and movement before you begin. Your joints must also be strong enough to support gait training. Once youre healthy enough to start gait training, the process is similar to other physical therapies. It often involves machines that help you walk safely. Your therapist may also assist you in gait training exercises. They can help support your bodyweight, provide stability, and offer other assistance. Gait training commonly involves walking on a treadmill and completing muscle strengthening activities. You may wear a harness while walking on the treadmill or doing other exercises. Your therapist may also ask you to practice stepping over objects, lifting your legs, sitting down, standing up, or other activities. The type, intensity, and ...
Although gait disorders are frequently associated with Alzheimers disease (AD), few studies have focused on their characterization and mechanism. Exploring the associations of the gait characteristics - more particularly the gait variability - with the cognitive performance of AD patients on one hand, and with the morphological brain abnormalities on the other hand, could be useful to understanding the mechanisms of gait disorders in AD.. The main objective of this study is to examine and to compare gait characteristics under single- and dual-task conditions among healthy subjects together with AD patients at different stages of disease (i.e., pre-dementia, mild and moderate dementia stages). ...
BACKGROUND: Fear of falling (FOF) and increased gait variability are both independent markers of gait instability. There is a complex interplay between both entities. The purposes of this study were (1) to perform a qualitative analysis of all published studies on FOF-related changes in gait variability through a systematic review, and (2) to quantitatively synthesize FOF-related changes in gait variability. METHODS: A systematic Medline literature search was conducted in May 2014 using the Medical Subject Heading (MeSH) terms Fear OR fear of falling combined with Accidental Falls AND Gait OR Gait Apraxia OR Gait Ataxia OR Gait disorders, Neurologic OR Gait assessment OR Functional gait assessment AND Self efficacy OR Self confidence AND Aged OR Aged, 80 and over. Systematic review and fixed-effects meta-analysis using an inverse-variance method were performed. RESULTS: Of the 2184 selected studies, 10 observational studies (including 5 cross-sectional studies, 4 prospective

[Subjects]: Seventy-two stroke patients in convalescent rehabilitation wards were enrolled. [Methods]: For gait ability, we evaluated gait velocity and gait variability. For physical function, we evaluated both motor and sensory functions of the affected lower limb, muscle tone of the ankle plantar flexor and muscle strength of both lower limbs. Using canonical correlation analysis, physical functions related to gait ability were explored. [Results]: As factors related to gait ability, muscle strength of both lower limbs and motor function of the ...
Stroke is a representative chronic disease with symptoms of movement and sensory disorders that affect the consciousness, language, cognition, and also cause paralysis [1,2]. Among them, motor neurons and sensory nerve damage cause stroke patients to have difficulty in daily life due to problems in balance and walking [3]. The main causes of such gait disturbances are decreased muscle activity, lack of balance sense, and reduced weight-bearing capacity [4], which limits the overall gait due to the slow gait cycle and reduced gait velocity [5]. Due to difficulties in performing daily life activities and requiring assistance, persons affected by stroke often exhibit low self-esteem, depression, and decreased quality of life [6].. Several studies have suggested various intervention methods to improve balance and walking ability for persons with stroke. Many studies have implemented treadmill gait training in patients with hemiplegia in order to improve postural symmetry by extending the weight ...
Background and Purpose: Conventional rehabilitation does not restore normal, upper limb function or normal gait to many stroke survivors. Functional neuromuscular stimulation (FNS) has shown promise for functional enhancement of both upper and lower limb motor control following stroke. Gains included muscle activation latencies, strength, coordination, upper limb functional tasks, gait kinematics, walking endurance, and quality of life. The purpose of the proposed work is to test the radio frequency-controlled (RF) Microstimulator (RFM) Gait System regarding system performance and subject response to treatment.. Methods: This is a feasibility study in which up to four subjects will receive the (RFM) Gait System. Up to ten RFMs will be placed for a given subject. An RFM ankle muscle system will be used to train ankle gait components. A separate RFM system will be used to train knee gait components. Subjects will be treated for 6 months, four sessions/wk. Primary outcome measures for the RFM Gait ...
The present study demonstrated a stepwise incremental increased risk of mortality after TAVR in patients with the slowest gait speed (,0.5 m/sec) or who were unable to walk compared with that for patients with a normal gait speed. In addition to traditional classification, specific survival CART analysis indicated that gait speed as 0.385 m/sec in this study population was an independent predictive factor of worse prognosis after TAVR. These trends were maintained after adjusting for differences in baseline patient characteristics. Gait speed assessment was also useful in predicting a poor prognosis in patients who underwent transfemoral TAVR. When patients were divided into low (STS ,4%), intermediate (STS 4-8), and high (STS ,8%) surgical risk groups, significant survival differences based on the gait speed classification were found among patients in the intermediate and high surgical risk groups. However, it was difficult to evaluate statistical differences in the low-risk group because of ...
High levels of gait asymmetry are associated with many pathologies. Our long-term goal is to improve gait symmetry through real-time biofeedback of a symmetry index. Symmetry is often reported as a single metric or a collective signature of multiple discrete measures. While this is useful for assessment, incorporating multiple feedback metrics presents too much information for most subjects to use as visual feedback for gait retraining. The aim of this article was to develop a global gait asymmetry (GGA) score that could be used as a biofeedback metric for gait retraining and to test the effectiveness of the GGA for classifying artificially-induced asymmetry. Eighteen participants (11 males; age 26.9 y [SD = 7.7]; height 1.8 m [SD = 0.1]; body mass 72.7 kg [SD = 8.9]) walked on a treadmill in 3 symmetry conditions, induced by wearing custom-made sandals: a symmetric condition (identical sandals) and 2 asymmetric conditions (different sandals). The GGA score was calculated, based on several joint ...
Abnormal sleep may associate with cognitive decline in Parkinsons disease (PD). Furthermore, sleep dysfunction may associate with worse motor outcome. We hypothesised that PD patients with poor quality sleep would have greater progression in gait dysfunction, due to structural and functional overlap in networks subserving sleep and gait regulation. 12 PD patients and 12 age-matched controls completed longitudinal follow-up over 36 months. Poor sleep efficiency and greater sleep fragmentation correlated significantly with progression of step-width variability, a gait characteristic mediated by postural control, providing evidence that poor sleep in PD is associated with a more rapid deterioration in gait.. ...

James S. Wrobel, D.P.M., M.S., and Bijan Najafi, Ph.D., M.S.. Background: Diabetic foot complications represent significant morbidity and precede most of the lower extremity amputations performed. Peripheral neuropathy is a frequent complication of diabetes shown to affect gait. Glycosylation of soft tissues can also affect gait. The purpose of this review article is to highlight the changes in gait for persons with diabetes and highlight the effects of glycosylation on soft tissues at the foot-ground interface.. Methods: PubMed, the Cochrane Library, and EBSCOhost® on-line databases were searched for articles pertaining to diabetes and gait. Bibliographies from relevant manuscripts were also searched.. Findings: Patients with diabetes frequently exhibit a conservative gait strategy where there is slower walking speed, wider base of gait, and prolonged double support time. Glycosylation affects are observed in the lower extremities. Initially, skin thickness decreases and skin hardness ...
Patients with neuromuscular disorders, such as poliomyelitis and Charcot-Marie-Tooth disease, frequently suffer from weakness or paresis of the calf muscles. Gait in calf muscle weakness is often characterised by excessive ankle dorsiflexion and persistent knee flexion during stance and by a reduced ankle push-off.1 These gait deviations nearly always lead to walking limitations such as instability,2 pain,3 ,4 reduced speed5 ,6 and an increased walking energy cost (EC),5-7 which may restrict walking activity in daily life.8-10. In normal gait, the calf muscles (gastrocnemius and soleus) prevent excessive ankle dorsiflexion, as the ground reaction force progresses over the foot in late stance. They create an eccentric force to restrain inclination of the shank,11 ,12 preventing the ankle from collapsing in uncontrolled dorsiflexion. This is followed by a concentric contraction of the calf muscles during push-off, which assists in propelling the limb forward into swing and inducing knee flexion.11 ...
DINI, PD e DAVID, AC. Repeatability of spatiotemporal gait parameters: comparison between normal children and children with hemiplegic spastic cerebral palsy. Rev. bras. fisioter. [online]. 2009, vol.13, n.3, pp.215-222. Epub 19-Jun-2009. ISSN 1413-3555. http://dx.doi.org/10.1590/S1413-35552009005000031.. OBJECTIVE: To evaluate the repeatability of spatiotemporal gait parameters by means of a comparative study between normal children and children with cerebral palsy (CP). METHODS: The sample consisted of 17 children divided into two groups: a group of nine children with spastic hemiplegia CP and a group of eight normal children. The children were evaluated by the same researcher in two different sessions, with a one-week interval between the sessions. The children walked at self-selected velocities, and six attempts were performed at each session to represent the average. To record the spatiotemporal parameters, the Peak Motus system was used with two SVHS video cameras with an acquisition rate ...
Quadrupedal locomotion is the result of complex interactions between biomechanical and neural systems. During steady gaits both systems are in stable states. When the animal changes its speed, transitions between gaits can occur where the different coordination parameters are dissociated. Consequently, transitions are the periods where it is possible to detect and identify those parameters involved in the mechanical or neural control of locomotion. We study the interlimb coordination using a sequential method (APS) to measure the footfall patterns of dogs when accelerating and decelerating from 1.5ms-1 to more than 6ms-1 and conversely. We obtained 383 transitions between all the symmetrical and asymmetrical gaits used by the dogs. The analysis of the interlimb coordination modifications and of each foot parameter showed that mechanics drive the stance phase whereas the coordination is controlled during the swing phase. Furthermore, the comparison of the transition patterns between all gaits ...

NGA were rated using standardized readings of video-recorded short ...
Gait-based features provide the potential for a subject to be recognized even from a low-resolution image sequence, and they can be captured at a distance without the subjects cooperation. Person recognition using gait-based features (gait recognition) is a promising real-life application. However, several body parts of the subjects are often occluded because of beams, pillars, cars and trees, or another walking person. Therefore, gait-based features are not applicable to approaches that require an unoccluded gait image sequence. Occlusion handling is a challenging but important issue for gait recognition. In this paper, we propose silhouette sequence reconstruction from an occluded sequence (sVideo) based on a conditional deep generative adversarial network (GAN). From the reconstructed sequence, we estimate the gait cycle and extract the gait features from a one gait cycle image sequence. To regularize the training of the proposed generative network, we use adversarial loss based on triplet hinge
TY - JOUR. T1 - Cortical facilitation of cutaneous reflexes in leg muscles during human gait. AU - Pijnappels, M.. AU - Van Wezel, B. M H. AU - Colombo, Gery. AU - Dietz, V.. AU - Duysens, J.. PY - 1998/3/16. Y1 - 1998/3/16. N2 - During human gait, cortical convergence on sural nerve reflex pathways was investigated by means of transcranial magnetic stimulation (TMS) of the cortex in five phases of the step cycle during human walking on a treadmill. Muscular responses to paired electrical and magnetic stimulation were compared with the linear summation of the individual stimuli. For both the tibialis anterior (TA) and biceps femoris (BF) muscles, the averaged data of four subjects showed a significant facilitation mainly in the swing phase of the step cycle. It is suggested that facilitation of corticospinal input onto cutaneous reflex pathways is enhanced specifically in these periods of the step cycle.. AB - During human gait, cortical convergence on sural nerve reflex pathways was ...
Background. No single intervention restores the coordinated components of gait after stroke. Objective. The authors tested the multimodal Gait Training Protocol, with or without functional electrical stimulation (FES), to improve volitional walking (without FES) in patients with persistent (|6 months) dyscoordinated gait. Methods. A total of 53 subjects were stratified and randomly allocated to either FES with intramuscular (IM) electrodes (FES-IM) or No-FES. Both groups received 1.5-hour training sessions 4 times a week for 12 weeks of coordination exercises, body weight-supported treadmill training (BWSTT), and over-ground walking, provided with FES-IM or No-FES. The primary outcome was the Gait Assessment and Intervention Tool (G.A.I.T.) of coordinated movement components, with secondary measures, including manual muscle testing, isolated leg movements (Fugl-Meyer scale), 6-Minute Walk Test, and Locomotion/Mobility subscale of the Functional Independence Measure (FIM). Results. No baseline

April Flowers for redOrbit.com - Your Universe Online. An international consortium of researchers from Uppsala University, Swedish University of Agricultural Sciences and Texas A&M University have discovered a mutation in a single gene in horses that is critical for the ability to perform ambling gaits and pacing that has a major effect on performance in harness racing. The study, published in Nature, is a breakthrough for understanding spinal cord neuronal circuitry and locomotion in vertebrates.. A complex coordination of muscle contractions carried out by neuronal circuits in our spinal cords allow us to walk and run, but how does this work at the level of nerve cells and molecules?. There is a great variability in the pattern of locomotion for horses, including the three naturally occurring gaits: walk, trot and canter/gallop. Some horses, however, have additional gaits such as ambling gaits or pace. For instance, Icelandic Horses can tolt (ambling gait) and flying pace. The team decided to ...
As in humans, several rodent gait parameters are correlated with body size. This study presents a body silhouette length computation method for rodents based on the recorded CatWalk videos. A correlational study was performed to investigate the relationship between the computed silhouette length and several CatWalk gait parameters. Accordingly, a silhouette-length-based scaling method on stride lengths and speed-related gait parameters is presented, which is able to reduce their correlation with body size. This silhouette-length-based scaling method cannot be directly replaced by silhouette-area-, body-weight-, or age-based scaling methods. As proof of concept, two rodent models of neurodegenerative disorders were investigated based on their scaled gait parameters. The results show smaller genotype-related differences compared with the nonscaled gait parameters due to the genotype-related body size difference.. The computed silhouette parameters, stride lengths, and speed-related gait parameters ...

Mobility impairment is common in people with multiple sclerosis (PwMS) and there is a need to assess mobility in remote settings. Here, the authors apply a novel wireless, skin-mounted, and conformal inertial sensor (BioStampRC, MC10 Inc.) to examine gait characteristics of PwMS under controlled conditions. The team determine the accuracy and precision of BioStampRC in measuring gait kinematics by comparing to contemporary research-grade measurement devices.. A total of 45 PwMS, who presented with diverse walking impairment (Mild MS = 15, Moderate MS = 15, Severe MS = 15), and 15 healthy control subjects participated in the study. Participants completed a series of clinical walking tests. During the tests participants were instrumented with BioStampRC and MTx (Xsens, Inc.) sensors on their shanks, as well as an activity monitor GT3X (Actigraph, Inc.) on their non-dominant hip. Shank angular velocity was simultaneously measured with the inertial sensors. Step number and temporal gait parameters ...
Cognitive problems in older adults range from mild impairment to severe dementia. The transitional stage between normal aging and dementia has been designated as Mild Cognitive Impairment (MCI) [1-3]. People with MCI have been found to have a 10 to 15 times higher risk of developing Alzheimers disease (AD), although up to 40% will not develop dementia [4, 5]. Prevalence of MCI is estimated at 19% among older adults, increasing to 29% in those over age 85 [6]. The prevalence of gait disorders also increases with age, with estimates of up to 20% in older people residing in the community [7]. Previously, age-associated slowing gait has been considered a benign consequence of aging; however, slow gait velocity has been recently associated with increased risk of falls, institutionalization, and mortality [8, 9]. Interestingly, gait slowing and cognitive impairment usually coexist in the same individual and the interaction between cognitive impairment and motor changes in older adults has been ...
In this work, we decided to apply a hierarchical weighted decision, proposed and used in other research fields, for the recognition of gait phases. The developed and validated novel distributed classifier is based on hierarchical weighted decision from outputs of scalar Hidden Markov Models (HMM) applied to angular velocities of foot, shank, and thigh. The angular velocities of ten healthy subjects were acquired via three uni-axial gyroscopes embedded in inertial measurement units (IMUs) during one walking task, repeated three times, on a treadmill. After validating the novel distributed classifier and scalar and vectorial classifiers-already proposed in the literature, with a cross-validation, classifiers were compared for sensitivity, specificity, and computational load for all combinations of the three targeted anatomical segments. Moreover, the performance of the novel distributed classifier in the estimation of gait variability in terms of mean time and coefficient of variation was evaluated. The
Research studies conducted in the Motion Analysis Core Facility typically focus on, but are not limited to, persons with amputations, persons with neuromuscular impairments, persons with musculoskeletal disorders or injuries, and healthy able-bodied individuals.. Quantitative Gait Analysis - A gait analysis is an experiment to record data about the way a person walks. Instrumentation included in a basic gait analysis includes a high speed digital motion capture system, force platforms, digital video recordings and digital photos. Reflective markers are placed on various anatomical landmarks on the participant. The participant is then asked to walk along a 10 m walkway a minimum of 5 times at varying speeds. Photos and digital recordings will be taken. Manual muscle testing using a handheld dynamometer will also be performed on the participants lower limbs to assess muscle strength. A goniometer will be used to measure the flexibility of the hip, knee, and ankle joints. Participation for an ...
Anti-dementia drugs may improve gait performance. No comparison between acetylcholinesterase inhibitors (CEIs) and memantine-related changes in gait variability has been reported. The objectives of this study were to 1) quantify and compare the mean values and coefficients of variation (CoV) of stride time in demented patients with Alzheimers disease and related disorders (ADRD) before and after the use of CEIs or memantine, and in age- and gender-matched controls patients with ADRD using no anti-dementia drugs; and 2) to determine whether changes in CoV of stride time differed between CEIs or memantine. A total of 120 demented patients with mild-to-moderate ADRD were prospectively included in this pre-post quasi-experimental study with two intervention groups (43 patients taking CEIs, and 41 taking memantine) and a control group (36 age- and gender matched patients without any anti-dementia drugs). CoV of stride time and walking speed were measured with GAITRite® system while usual walking at steady
Gait independence is one of the most important factors related to returning home from the hospital for patients treated in the intensive care unit (ICU), but the factors affecting gait independence have not been clarified. This study aimed to determine the factors affecting gait independence at hospital discharge using a standardized early mobilization protocol that was shared by participating hospitals. Patients who entered the ICU from January 2017 to March 2018 were screened. The exclusion criteria were mechanical ventilation | 48 hours, age | 18, loss of gait independence before hospitalization, being treated for neurological issues, unrecoverable disease, unavailability of continuous data, and death during ICU stay. Basic attributes, such as age, ICU length of stay, information on early mobilization while in the ICU, Medical Research Council (MRC) sum-score at ICU discharge, incidence of ICU-acquired weakness (ICU-AW) and delirium, and the degree of gait independence at hospital discharge, were
Five-gaited horses are notable for their ability to perform five distinct horse gaits instead of simply the three gaits, walk, trot and canter or gallop common to most horses. Individual animals with this ability are often seen in the American Saddlebred horse breed, though the Icelandic horse also has five-gaited individuals, though with a different set of gaits than the Saddlebred. The ability to perform an ambling gait or to pace appears to be due to a specific genetic mutation. Some horses are able to both trot and perform an ambling gait, but many can only do one or the other, thus five-gaited ability is not particularly common in the horse world. In the American Saddlebred and related breeds, the five gaits performed are the walk, trot, canter, and two ambling gaits: the rack, a fast, lateral, four-beat gait that is synchronous- "each foot meets the ground at equal, separate intervals"; and a "slow gait", a slower, smooth collected four-beat gait that is asynchronous - "the lateral front ...

Here, we investigate the role of sensory feedback in gait generation and transition by using a three-dimensional, neuro-musculo-mechanical model of a salamander with realistic physical parameters. Activation of limb and axial muscles were driven by neural output patterns obtained from a central pattern generator (CPG) which is composed of simulated spiking neurons with adaptation. The CPG consists of a body-CPG and four limb-CPGs that are interconnected via synapses both ipsilaterally and contralaterally. We use the model both with and without sensory modulation and four different combinations of ipsilateral and contralateral coupling between the limb-CPGs. We found that the proprioceptive sensory inputs are essential in obtaining a coordinated lateral sequence walking gait (walking). The sensory feedback includes the signals coming from the stretch receptor like intraspinal neurons located in the girdle regions and the limb stretch receptors residing in the hip and scapula regions of the ...

TY - JOUR. T1 - Non-ideal behavior of a treadmill depends on gait phase, speed, and weight. AU - Tielke, Austin. AU - Ahn, Jooeun. AU - Lee, Hyunglae. PY - 2019/12/1. Y1 - 2019/12/1. N2 - Noticeable differences exist between treadmill and overground walking; kinematics, kinetics, and muscle activation patterns differ between the two. Many previous studies have attributed the differences to changes in visual information, air resistance, and psychological effects such as fear. In this study, we demonstrate that no treadmill serves as an inertial frame of reference. Considering the linear momentum principle, the finite sampling rate of the controller, and the limited power of the treadmill motor, we predict that 1) the error of the treadmill speed periodically varies depending on the locomotion phase and 2) this non-ideal behavior becomes more evident as the locomotion speed or the weight of the walker increases. Experimental observation confirmed our predictions by quantifying the variation of the ...
An ambling gait or amble is any of several four-beat intermediate horse gaits, all of which are faster than a walk but usually slower than a canter and always slower than a gallop. Horses that amble are sometimes referred to as "gaited," particularly in the United States. Ambling gaits are smoother for a rider than either the two-beat trot or pace and most can be sustained for relatively long periods of time, making them particularly desirable for trail riding and other tasks where a rider must spend long periods of time in the saddle. Historically, horses able to amble were highly desired for riding long distances on poor roads. Once roads improved and carriage travel became popular, their use declined in Europe but continued in popularity in the Americas, particularly in areas where plantation agriculture was practiced and the inspection of fields and crops necessitated long daily rides. The ability to perform an ambling gait is usually an inherited trait. In 2012, a DNA study found that ...
Parkinsons disease (PD) is a movement disorder traditionally thought to be caused by the degeneration of striatal dopaminergic neurons in the substantia nigra. One of the most devastating symptoms of PD that can decrease mobility and substantially impair quality of life is freezing of gait (FOG). Currently, the treatments for the motor symptoms of PD (e.g., levodopa, deep brain stimulation) are ineffective at managing FOG as the disease progresses. These treatments only target the cortical-striatal pathways of volitional movement that are dependent on dopamine, whereas FOG may be caused by the degeneration of other non-dopaminergic subcortical nuclei that are involved with posture and gait control (e.g., the pedunculopontine nucleus). A well-characterized behavior observed in PD that could contribute to FOG is a diminished ability to properly coordinate anticipatory postural adjustments (APAs) prior to the first step. In particular, diminished muscle activation leads to impaired limb mechanics ...

The principal finding of this study is that 5-m gait speed is an incremental predictor of mortality and major morbidity in elderly patients undergoing cardiac surgery, associated with a 2- to 3-fold increase in risk. This simple, rapid, and inexpensive test effectively stratifies patients beyond traditional estimates of risk, which tend to be inaccurate in the elderly. Addition of gait speed to existing cardiac surgery risk models resulted in improved model performance, translating into more accurate prediction of who will experience a major adverse post-operative event and who will need to be discharged to a health care facility for ongoing medical care or rehabilitation.. There are no previous studies specifically focusing on the use of gait speed as a predictor of post-operative mortality and morbidity in elderly cardiac surgery patients. Two studies incorporated disabilities in activities of daily living as a predictor of outcomes after cardiac surgery (26,27). Although there is no ...
article{2a540d9f-73ba-41d7-8442-fe16f20afb72, abstract = {,p,Emerging evidence suggests that the basis for variation in late-life mobility is attributable, in part, to genetic factors, which may become increasingly important with age. Our objective was to systematically assess the contribution of genetic variation to gait speed in older individuals. We conducted a meta-analysis of gait speed GWASs in 31,478 older adults from 17 cohorts of the CHARGE consortium, and validated our results in 2,588 older adults from 4 independent studies. We followed our initial discoveries with network and eQTL analysis of candidate signals in tissues. The meta-analysis resulted in a list of 536 suggestive genome wide significant SNPs in or near 69 genes. Further interrogation with Pathway Analysis placed gait speed as a polygenic complex trait in five major networks. Subsequent eQTL analysis revealed several SNPs significantly associated with the expression of PRSS16, WDSUB1 and PTPRT, which in addition to the ...

Background: Previous studies have demonstrated that post-stroke gait rehabilitation combining functional electrical stimulation (FES) applied to the ankle muscles during fast treadmill walking (FastFES) improves gait biomechanics and clinical walking function. However, there is considerable inter-individual variability in response to FastFES. Although FastFES aims to sculpt ankle muscle coordination, whether changes in ankle muscle activity underlie observed gait improvements is unknown. The aim of this study was to investigate three cases illustrating how FastFES modulates ankle muscle recruitment during walking. Methods: We conducted a preliminary case series study on three individuals (53-70 y; 2 M; 35-60 months post-stroke; 19-22 lower extremity Fugl-Meyer) who participated in 18 sessions of FastFES (3 sessions/week; ClinicalTrials.gov: NCT01668602). Clinical walking function (speed, 6-min walk test, and Timed-Up-and-Go test), gait biomechanics (paretic propulsion and ankle angle at ...

Improving Physical Activity And Gait Symmetry After Total Knee Arthroplasty PubMed Journal Articles published on BioPortfolio | BioPortfolio
Greater amounts of weight-bearing asymmetry (WBA) 1 month after total knee arthroplasty (TKA) are predicted by modifiable factors, including habitual movement pattern and asymmetry in quadriceps and hamstrings strength, say authors of an article published online in Gait & Posture. Fifty-nine people were tested preoperatively and 1 month following unilateral TKA for WBA using average vertical ground reaction force under each foot during the Five Times Sit-to-Stand Test. Candidate variables tested in the regression analysis represented physical impairments (strength, muscle activation, pain, and motion), demographics, anthropometrics, and movement compensations.. WBA, measured as the ratio of surgical/nonsurgical limb vertical ground reaction force, was 0.69 (0.18) (mean (SD) 1 month after TKA. Regression analysis identified preoperative WBA, quadriceps strength ratio, and hamstrings strength ratio as factors predictive of WBA 1 month after TKA (R(2)=0.30).. APTA member Cory L.

Objective: To investigate the neural correlates of hypokinetic gait in Parkinsons disease (PD) using functional magnetic resonance imaging (fMRI). Background: Although hypokinetic gait is frequent and has a negative impact on quality of life in PD, its underlying mechanisms remain poorly understood. Assuming that the brain regions recruited during real and imagined gait strongly overlap, mental imagery of brisk gait may be a successful approach to study hypokinetic gait in PD. Methods: Fifteen on-drugs PD patients (8 males; mean age 5 65.1 6 9.4 years) and fifteen controls matched for age, gender and mental imagery skills were trained to perform video-taped trials of comfortable and brisk gait on a 25 meter-path. The study was organ- ized as a block-design fMRI ...
List of 39 causes for Gait disorder and Scissor gait in children, alternative diagnoses, rare causes, misdiagnoses, patient stories, and much more.
The first thing you notice is that these three different athletes ran the same speed until the last 2 laps or so. Thats to be expected, but what is interesting is that they had different strategies to do it. Bekele had a low stride frequency with a long stride length for the first 9,000m. On the other hand, Mathathi had a small stride length and a very high frequency to run the same speed. Sihine was somewhere in between these two. What is also interesting is that Mathathi who is 1.67m tall and Sihine who is 1.71m tall both had considerably smaller stride lengths than Bekele who is only 1.60m tall. So, all you shorter runners complaining about how your height keeps you from having a long stride, just look towards Bekele. The point is though that we have three runners all employing different strategies to run the same speed.. It gets even more interesting when we look at the last 1km when the pace changed dramatically. For reference they went from hitting around 2:42-2:45 for each km to final km ...

A system and method for measuring and analyzing locomotion is provided. The system may include a gait analysis apparatus that is configured to provide multi-dimensional measurements of the gait of an individual as the individual traverses the apparatus. The multiple dimensions may include force, space, time, and frequency. The gait analysis apparatus may be configured to provide a gait measurement processing device with the multi-dimensional measurements. Based on the multi-dimensional measurements, the gait measurement processing device may, for example, diagnose the test subject with a particular NM disease and/or injury, monitor progression of the particular NM disease and/or injury over time, and determine which measurements may be used as biomarkers to identify the particular NM disease and/or injury.
The typical walk consists of a repeated gait cycle. The cycle itself contains two phases - a stance phase and a swing phase: Stance phase: Accounts for 60% of the gait cycle. It can be divided into the heel strike, support and toe-off phases.
Computer simulation has been used to investigate several aspectsof locomotion in salamanders. Here we introduce a three-dimensionalforward dynamics mechanical model of a salamander, with physicallyrealistic weight and size parameters. Movements of the four limbs and ofthe trunk and tail are generated by sets of linearly modeled skeletalmuscles. In this study, activation of these muscles were driven byprescribed neural output patterns. The model was successfully used tomimic locomotion on level ground and in water. We compare thewalking gait where a wave of activity in the axial muscles travelsbetween the girdles, with the trotting gait in simulations usingthe musculo-mechanical model. In a separate experiment, the model is usedto compare different strategies for turning while stepping; either bybending the trunk or by using side-stepping in the front legs. We foundthat for turning, the use of side-stepping alone or in combination withtrunk bending, was more effective than the use of trunk bending alone.
Spinal orthoses are common in the treatment of various conditions that affect the spine. They encompass both the spine and pelvis and thus have implications for pelvic and lower-limb motion during walking in addition to a direct effect on spinal motion. The role of the spine in walking is largely ill-defined, and the consequences of restricted spinal motion on walking have yet to be explored. This study investigated the effect of spinal restriction on gait in able-bodied persons. Gait analyses were performed on 10 able-bodied subjects as they walked at five different speeds that were distributed across their comfortable range of speeds. Data were collected during walking with and without spinal restriction by a fiberglass body jacket, which is similar to a thoracolumbosacral orthosis (TLSO). With spinal restriction, peak-to-peak (PP) pelvic obliquity and rotation were significantly reduced across all walking speeds (p < 0.001), while PP pelvic tilt was significantly reduced at only the fastest ...

The most commonly observed sequel after stroke is muscle weakness, which can also be identified in respiratory muscles, in the acute and chronic phases, and may compromise the lung function of these individuals. Studies have shown that lower Pimax values are found in non-community ambulators, and gait velocity has been reported as an important indicator of functionality after stroke, with higher gait velocity values associated with greater community participation and better quality of life. This study will test the hypothesis that training of the inspiratory muscles is effective in improving strength and endurance of the inspiratory muscles and functionality, including speed of gait, functional gait perfomarnce, activities of daily living and quality of life with stroke subjects. For this clinical trial, people after stroke will be randomly allocated into either experimental or control/sham groups. The experimental group will undertake training of the inspiratory muscles with the Power Breath ...
Timed walking tests are valid measurements to predict community walking in patients with Parkinson disease, say authors of an article published online in Journal of Rehabilitation Medicine. However, evaluation of community walking also should include an assessment of fear of falling, they add. For this investigation, researchers used data from baseline assessments in a randomized clinical trial. A total of 153 patients with Parkinson disease were included. Community walking was evaluated using the mobility domain of the Nottingham Extended Activities of Daily Living Index. Patients who scored 3 points on item 1 ("Did you walk around outside?") and item 5 ("Did you cross roads?") were considered community walkers. Gait speed was measured with the 6-meter or 10-meter timed walking test. Age, gender, marital status, disease duration, disease severity, motor impairment, balance, freezing of gait, fear of falling, previous falls, cognitive function, executive function, fatigue, anxiety, and ...

The pediatric Gait Analysis Lab at Nemours/Alfred I. duPont Hospital for Children, Wilmington, is used to diagnose gait problems in children.
Gait and balance problems resulting from Parkinsons disease (PD) are more common in people with PD and dementia (PDD), yet, it is unknown whether the benefits of cueing therapy for mobility generalize to them. We aimed to determine the feasibility and effectiveness of auditory cues to improve gait in PD and cognitive impairment (PD-CI). Nine participants with PD-CI walked with and without auditory cues using two different strategies: (1) Cue with temporal instruction to "step in time to the beat," (2) Cue with spatiotemporal instruction to "take a big step in time to the beat." Cues were delivered with a metronome at preferred stepping frequency while on medication during single and dual-task gait. Gait was assessed using GAITRite and walking speed, stride amplitude, step frequency, and variability (CV%) of step and double limb support time were measured. Data were analyzed in SPSS version 16 using fixed-effect linear mixed models. An adjusted, P value of 0.01 was considered significant. ...

Background/Purpose: Approximately 15,000 Veterans are hospitalized for stroke each year. Impairments of motor control and the subsequent functional limitations in ambulation are the most common manifestations and regaining the ability to walk is the number one stated goal of Veteran stroke survivors. Forward propulsion of the bodys center of mass is a cardinal feature of gait that depends on the generation of appropriate anterior-posterior ground reaction forces. Decreased propulsive force generation by the paretic limb of stroke survivors has been identified through both simulation and cross-sectional studies as a major contributor to walking dysfunction. Extrinsic verbal feedback from a therapist is the standard approach used during gait retraining to improve propulsion generation. However, this key component of gait is not directly observable by therapists and patients are often unable to sense propulsion generation due to impaired intrinsic feedback, specifically deficits in somatosensation ...
Background: Knee joint pain (KJP) independently alters motor function and gait mechanics, and these alterations may accelerate chronic knee joint disease. While TENS restores motor function deficits, it is unclear whether TENS restores compensatory gait mechanics. The purpose was to examine the effects of KJP on lower-extremity joint moments, and the effects of TENS on the aforementioned variables. We hypothesized that KJP will result in altered gait patterns, and TENS will help restore these mechanical alterations. Methods: We randomly selected 15 subjects for the TENS group, after which subjects were matched for the placebo group. Subjects underwent 3 sessions (hypertonic, isotonic, control). A 20-gauge flexible catheter was inserted into the right infrapatellar fat pad, and an infusion pump infused a saline of 0.154 mL•min¯¹ for 50 min (total = 7.7 mL). A TENS protocol was set at a biphasic mode with 120 µs and 180 Hz for 20 min. To blind placebo treatment, subjects in the placebo group ...

Segment 1. This shows that the patient could walk normally with eyes open. Tandem gait performance was unremarkable. However, the pull test was very abnormal, and with each shoulder pull the patient fell backwards in the hands of the examiner, without making any attempts to correct.Segment 2. This shows the Romberg test. Immediately after eye closure, the patient fell backwards like a log into the hands of the two examiners, again without any attempts to prevent a fall.Segment 3. In this we asked the patient to walk with eyes closed, and this produced an unexpected effect. Shortly following eye closure, the patient began to gradually lean backwards, requiring help from two assistants to prevent her from falling. However, despite this backward inclination, she continued to make stepping movements, and this continued even when she was lying on her back on the floor. The recumbent walking movements continued until we asked the patient to open her eyes, at which point she reported finding herself ...
If you have been running with the same person for a while, or if you have watched the same person run often enough, you begin to notice their stride and gait until you can eventually recognize it from far away. Years and years ago, my husband commented on "that thing I do with my foot.". "What do you mean?" I asked.. "You swing it out, or you kick it out. I dont know. Its just weird. But I can see you from a mile away.". Of course, I still carefully look at every photo of me running. Am I doing "that thing with my foot?" Yes. And, even though I have known about it for years, I havent been able to change it. I have always attributed it to my one leg being longer than the other; my body has had to accommodate for that when I am running ...

Authors: Hegeman, Judith , Shapkova, Elena Yu , Honegger, Flurin , Allum, John H.J. Article Type: Research Article Abstract: The aim of the studies reported here was to quantify changes in balance control for stance and gait tasks with age and to pinpoint possible advantages and difficulties in using these tasks and measures derived from them to identify pathological balance control in patients. Some 470 normal subjects in the age range 6 to 82 were examined for a battery of 14 stance and gait tasks. During the tasks, angular velocity transducers mounted at lumbar 1-3 …measured pitch and roll angular velocities of the body. A combination of outcome measures from several tasks was used to create an overall balance control index. Three types of sensory analyses on pitch angle and velocity amplitudes for stance trials were used to quantify possible changes in the contributions of visual, somatosensory and vestibular inputs to balance control with age for 2-legged stance tasks.
