The overall aim of this thesis was to investigate postural balance, physical activity, physical capacity and their associations in young people (16-20 years) with intellectual disability (ID), mild to moderate. The aim was also to study the reliability and concurrent validity of postural balance tests.. To evaluate postural balance, one assessor used five common postural balance tests and one new test. The tests were performed twice for 89 young people with ID (one to twelve days apart). Intraclass correlation coefficients greater than 0.80 were achieved for four of the common balance tests: Extended Timed Up and Go Test (ETUGT), Modified Forward Reach Test (MFRT), One-Leg Stance Test (OLS), and a Force Platform Test (FPT). The smallest real difference ranged from 12% to 40%; less than 20% is considered to be low. For the six balance tests, the concurrent validity varied between none to low.. Falls are more common for young people with ID compared to young people without ID. One reason could be ...
Background: Impaired postural balance is a common symptom after stroke and a common cause of falling. Most common daily tasks use arm and hand movements. Impairment in an upper extremity is a common stroke symptom, affecting 50-80% in the acute phase after stroke, and 40-50% in the sub-acute phase. The impact of leg function on postural balance has been investigated in several studies, but few have stressed the importance of arm function on postural balance. Objective: To explore whether there is any association between arm function and postural balance after stroke. Method: A cross sectional study where 121 adults (mean age: 70 +/- 12.3 years, 72 men) from two different data sources, Gothenburg Very Early Supported Discharge (GOTVED), and a study by Carvalho et al. were merged. Time for assessments ranged from 1 to 13 years when the patients were in the chronic phase. The dependent variables were Berg Balance scale (BBS) and Time Up and Go (TUG) both dichotomized to "impaired postural balance" ...
Comparison of the Mini-Balance Evaluations Systems Test with the Berg Balance Scale in relationship to walking speed and motor recovery post stroke
For adolescent people with ID, falls are more common compared to peers without ID. However, postural balance among this group is not thoroughly investigated. The aim of this study was to compare balance and muscle performance among adolescents aged between 16 and 20 years with a mild to moderate intellectual disability (ID) to age-matched adolescents without ID. A secondary purpose was to investigate the influence of vision, strength, height and Body Mass Index (BMI) on balance. A group of 100 adolescents with ID and a control group of 155 adolescents without ID were investigated with five balance tests and three strength tests: timed up and go test, one leg stance, dynamic one leg stance, modified functional reach test, force platform test, counter movement jump, sit-ups, and Biering-Sørensen trunk extensor endurance test. The results showed that adolescents with an ID in general had significantly lower scores in the balance and muscle performance tests. The group with ID did not have a more ...

The aim of this study was to establish the inter-rater reliability of the Functional Balance test for Geriatric patients (FBG) and concurrent validity between the FBG and the Berg balance scale, and to present reference values for the FBG. Patients (n = 22) aged between 66 and 87 years with varying diagnoses and elderly subjects without balance problems (n = 145) were assessed. The inter-rater reliability, calculated with intraclass correlation (ICC2.1) for FBG total was 0.99. Cohens kappa coefficient (κ) varied between 0.83 and 0.94 for the four items in the FBG. The correlation between the total scores for FBG and the Berg balance scale, calculated with Spearmans rank correlation coefficient (rs) had a correlation of 0.96. The reference value for FBG total was 24 for men and woman aged 65-69 years, 23 for men and woman aged 70-79 years, 22 for men 80 years and older, and 21 for woman 80 years or older.. ...
The Sitting Balance Scale is comparable to the Trunk Impairment Scale for measuring sitting balance in older adults who are nonambulatory or have limited mobility, say authors of an article published in Clinical Rehabilitation. The authors conducted this prospective study in acute care, inpatient rehabilitation, skilled nursing facility, and home health settings. Participants included 98 patients, with a mean age of 80.5 (SD 7.9) years, who received physical therapy (n = 20 acute care, n = 18 inpatient rehabilitation, n = 30 skilled nursing facility, n = 30 home setting). Nineteen patients were nonambulatory, and 79 had limited functional mobility with Timed Up and Go scores ≥20 seconds. The main measures were the Sitting Balance Scale, Trunk Impairment Scale, Timed Up and Go, length of stay, and setting-specific clinical measures of sitting balance (OASIS-C M1850; MDS G-3b).. A moderate association between ambulatory status and sitting balance measures was found (Sitting Balance Scale r = ...

Athletic balance occurs as a result of both skill training and specific balance training. Regardless of how much balance training is done, if an athlete does not know how to move and position their body to execute a skill in the most efficient manner they will never have good balance. Skill instruction should focus on not just the skill itself but follow through positions and preparation to react following the skill, this will greatly enhance balance and overall performance. Athletic balance can be divided into two major sub categories static balance and dynamic balance. Static balance, often referred to as stability, is used to hold or maintain a body position. Gymnasts use static balance to hold a cross on the rings or support themselves on the parallel or uneven bars. A basketball or hockey player would need static balance when trying to hold a position in front of the net or in the low post. Static balance requires the ability to react to an external force that is attempting to upset an ...
Balance problems and falls are a common concern among individuals with Parkinsons disease (PD). Falls frequently occur during daily activities such as reaching into cupboards in the kitchen or bathroom. This study compared the correlation among two standard postural stability tests - the postural stability score on the Unified Parkinsons Disease Rating Scale (UPDRS) and the Functional Reach Test (FRT) - and ecologically valid reaching tasks that correspond to reaching at different cupboard heights among 20 individuals with PD and 20 age-matched controls. Both the FRT and the UPDRS postural stability tests are quick measures that can be performed during the clinical examination. The FRT, but not the postural stability score, demonstrated a significant correlation with the ecologically valid reaching tasks, among individuals with PD. Furthermore the FRT scores did not correlate with the UPDRS postural stability scores, indicating that these are measuring different aspects of balance. This study suggests
Context: Clinical and functional assessments are performed regularly in sporting environments to screen for performance deficits and injury risk. Circadian rhythms have been demonstrated to affect human performance; however, the influence of time of day on a battery of multiple ankle injury risk factors has yet to be established within athletic populations. Objectives: To investigate the influence of circadian variation on a battery of tests used to screen for ankle etiological risk factors. Design: Randomized crossover design. Setting: University laboratory. Participants: A total of 33 semiprofessional soccer players (age = 24.9 [4.4] y; height = 1.77 [0.17] m; body mass = 75.47 [7.98] kg) completed 3 randomized experimental trials (07∶00, 12∶00, and 19∶00 h).

Participants: Forty-two eligible subjects with PD were randomly allocated into balance with focus of anticipatory and compensatory postural control (EXP) or control (CON) group with strength-focused training, with 26 subjects in each group.. Methods: Subjects in the EXP group were trained the speed and amplitude of anticipatory postural adjustment during stepping and walking and postural response to perturbation during walking. Subjects In the CON group were trained to improve the strength of lower limb muscles. Treatment period in both groups lasted for 12 weeks, which consisted of 4-week laboratory-based training (phase 1), 4-week home-based exercise (phase 2) and final 4-week laboratory-based training (phase 3). Outcome measures included reaction time(RT), movement velocity (MV) and endpoint excursion (EPE) of limit-of-stability test, one-leg-stance (OLS) time, gait velocity, stride length (SL), cadence, and fall rate. All tests were conducted for 6 time intervals including baseline, after ...

Spinal cord injury (SCI) can damage long tracts, affecting postural stability. Impairments in balance have recently been proposed to be highly predictive of functional recovery in patients with SCI and thus merit evaluation. In addition to common observational clinical scales, more objective evaluation methods of balance can be implemented by analyzing center of pressure (COP) parameters using stabilometric platforms (SPs). COP analysis has been used in various pathologies, but the COP parameters with regard to measurement vary, depending on the features of the target population, and have only been assessed in healthy subjects. Specifically, concerning subjects with SCI, few studies have reported COP parameters, and none has addressed the reliability, validity, or responsiveness of this measure. The objective of this serial cross-sectional study was to analyze the reliability, validity, and responsiveness of COP parameters under various conditions in incomplete SCI subjects to assess balance.

People with multiple sclerosis (MS) often have affected balance capacity and an increased risk for falls. A risk factor for falls are activities requiring dual attention. Another factor leading to reduced balance capacity is trunk stability, and decreased trunk stability has been seen in people with MS compared to healthy controls. Earlier studies using core stability exercises have shown positive effects on balance, compared to no training. In Sweden, physical therapy for people with MS has often included group training. However, evidence for this intervention is scarce. The aim of this study is therefore to investigate balance training in group. The balance training includes core stability exercises and dual attention activities. A multi-centre study is planned with a waiting-list design. Participants are randomised to either exercise group with early start or with late start. The group balance training includes training 60 minutes 2 times per week for 7 weeks ...
Background/Purpose. Previous studies suggest that FM may be associated with worse balance and falls. Balance requires the coordination of motor, sensory (ex. visual and vestibular), and cognitive abilities. These may be affected by the psychological symptoms present in FM. Depression, anxiety, and stress, have both cognitive (reduced attention) and somatic features (poor sleep quality and psychomotor slowing); and may therefore be related to the balance problems in FM. We intend to evaluate these relationships in this study. Methods. We analyzed baseline data from a randomized trial comparing Tai Chi to aerobic exercise in individuals with FM. Balance was measured using a One-Leg Balance Test (OLBT): time standing on preferred leg with eyes closed; max time = 30 seconds. Psychological symptoms of depression, anxiety, and stress were measured using validated scales: Beck Depression Inventory (BDI-II); Participant-Reported Outcomes Measurement Information System (PROMIS) Emotional Distress rating ...
TY - JOUR. T1 - Effects of different movement strategies on forward reach distance. AU - Liao, Chien Fen. AU - Lin, Sang-I. PY - 2008/7/1. Y1 - 2008/7/1. N2 - The functional reach test (FRT) is a reliable and frequently used test to measure dynamic balance ability clinically. However, it is not clear if reach strategy would affect the association between reach distance and dynamic balance. The purpose of this study was to investigate the extent to which reach distance reflected dynamic balance in different reaching strategies. Thirty-three healthy young adults performed the FRT that required subjects to stand with the feet shoulder width apart and one arm raised to 90°, and then reach forward as far as possible without moving the feet or losing balance. Two additional instructions were given to induce different strategies: keeping the raised arm at 90° throughout the test, and reaching toward a shoulder-height target. The kinematics was recorded using a Vicon motion system, and the hip, ankle ...

Introduction Sitting balance may be affected by stroke, resulting in functional impairment and reduced mobility. Early return of sitting balance predicts greater return of motor function and mobility after stroke. Task-specific therapy is effective but patients must be motivated to perform the exercises repeatedly for the greatest benefit. Virtual reality training (VRT) allows patients to do exercises while interacting with a video game interface. It is enjoyable and may encourage repetition of therapeutic exercises. Past work in our laboratory showed that standing balance exercises performed with VRT produced additional improvements in gait speed and leg function over traditional inpatient rehabilitation (1). Because of legislative change in Ontario most stroke rehabilitation inpatients today cannot stand independently. There have been no studies on the effect of VRT on sitting balance. Purpose To assess whether additional sitting balance exercises performed via VRT can improve sitting balance ...
OBJECTIVE: To compare Kendo players with active elderly adults in terms of quality of life, functional aspects (muscle strength, postural balance) and body composition. METHODS: This was a controlled cross-sectional study. Twenty elderly individuals were divided into two groups: the Kendo group, with an average age of 71.8 (5.4) years, and the Control group, with an average age of 73.1 (4.8) years. Quality of life was evaluated using a questionnaire (WHOQOL-bref and WHOQOL-old); body composition was evaluated with a bioimpedance scale (InBody230); hand-grip strength was assessed with a portable manual dynamometer (Jamar SH 5001); flexor and extensor muscle strength of the knees was evaluated with an isokinetic device (Biode® System 3 model Biodex Multi Joint System, BIODEX); and dynamic balance was assessed using a force platform (Balance Master System, Neurocom International, Inc ...

Numerous studies have proven that people with better posture, better balance, and greater muscle power are less likely to fall and are therefore less likely to be injured or experience a fracture. An interesting study performed in Japan, sometimes referred to as the "Flamingo Study" showed that standing on 1 foot to balance 3 times per day for 1 minute each (6 minutes in total - 3 times on each foot for 1 minute each per day) was effective in helping improve balance and prevent falls. This is called the unipedal balance exercise and the study is entitled: Effects of unipedal standing balance exercise on the prevention of falls and hip fracture among clinically defined high-risk elderly individuals: a randomized controlled trial. According to the principal author, K. Sakamoto, "Unipedal standing captures the 2.75 times weight load to the femoral head. Unipedal standing for one minute is equivalent to the amount of integral load gained through walking for approximately 53 minutes. Unipedal ...

A group of disorders that impair the functioning of the human balance system which depends on the inner ear, the eyes, and the muscles and joints to transmit reliable information about the bodys movement and orientation. When the inner ear or other elements of the balance system are damaged, the result may be vertigo, dizziness and imbalance which make the individual susceptible to falling. Other symptoms include vision problems (difficulty focusing, light sensitivity, poor depth perception), hearing loss, tinnitus (a sensation that is often referred to as ringing in the ears, although some people hear hissing, roaring, whistling, chirping, or clicking), difficulty concentrating, disorientation, mental and/or physical fatigue, nausea and vomiting. Not all symptoms are experienced by every person with a balance disorder and additional symptoms are possible. Conditions that can lead to balance problems include bacterial or viral infections, head injuries, stroke, orthopedic injuries, ...
Brain insulin has had widespread metabolic, neurotrophic, and neuromodulatory functions and has been involved in the central regulation of food intake and body weight, learning and memory, neuronal development, and neuronal apoptosis. Purpose: The present study investigated the role of swimming training on cerebral metabolism on insulin concentrations in cerebellum and the body balance performance of diabetic rats. Methods: Forty Male Wistar rats were divided in four groups: sedentary control (SC), trained control (TC), sedentary diabetic (SD), and trained diabetic (TD). Diabetes was induced by alloxan (32 mg kg b.w.), single dose injection. The mean blood glucose of diabetic groups was 367 ± 40 mg/dl. Training program consisted in swimming 5 days/week, 1 h/day, 8 weeks, supporting a workload corresponding to 90% of maximal lactate steady state (MLSS). For the body balance testing rats were trained to traverse for 5 min daily for 5-7 days. All dependent variables were analyzed by one-way ...
Virtual time to contact (VTC) is a measure of postural stability that estimates the virtual time it would take to reach an individuals stability boundary. This study aimed to validate VTC as measured by a depth sensor and determine whether VTC from the depth sensor distinguishes between older adult fallers and nonfallers compared with a force platform. VTC was assessed in 10 young and 20 older adults by having participants lean in a circular direction followed by 5 balance tests: eyes open, dual task, eyes open foam, eyes closed, and eyes closed foam. Spearman rank correlations and Bland-Altman plots were conducted to determine validity, and receiver operating characteristic curves were constructed to discriminate between fallers and nonfallers. Significant correlations were found in the dual task (P = .03), eyes open foam (P , .01), and eyes closed foam conditions (P = .05). The depth sensor discriminated between fallers and nonfallers in the eyes open (P = .02), dual task (P = .03), and eyes ...
The birds skeleton appears to be the key. As with humans, flamingos have two main joints on their leg. The one you can see, that bends backward, is not the knee. Thats actually the birds ankle. Its knee, meanwhile, is hidden in birds features at the fatter part of its body.. When the flamingo is ready to nod off, it lifts one leg and instinctively moves its body so its single foot isnt under its hip. Instead, its centered directly under the carriage of bird. Meanwhile, pulling the other leg up forces the knee to bend, which the flamingo rests on. All the joints essentially snap into place.. "If you look at the bird from the front, while theyre standing on one leg, the foot is directly beneath the body, which means that their leg is angled inward. Thats the pose you have to strike in order to engage the stay mechanism," Chang told the BBC.. As the flamingo remains nearly perfectly still while sleeping, gravity does the rest, keeping the bird in place.. While the how doesnt necessarily ...

Suddenly balance is not so certain. Call in the balance mechanic-but wait, thats you! If the thought of you working on somebody elses balance difficulties is leaving you feeling like a deer in the headlights, then this chapter is for you. Good balance training, especially for groups where individual needs vary, should be comprehensive and include as many elements for balance as possible. Include activities for flexibility, posture, and strength, as well as traditional balance components and everyday skills (see chapter 1 for a discussion on multicomponent training). The Senior Fitness Test Manual (Rikli and Jones, 2001) has several tests that can be easily used for groups or individuals. The tests are easy to do and are well validated with norms presented. I most frequently use the flexibility, strength, endurance, and Get Up and Go tests. Debra Roses FallProof (2003) offers tests that are more balance-oriented, including the Fullerton Advanced Balance (FAB) scale; Rose also presents a very ...
Running & pregnancy is a topic near and dear to my heart, as it was the time in my life when I was pregnant with my first child (in 2002!!) that the seeds for what is now Balance Personal Fitness Training were planted.. Once Balance blossomed, Running on Balance came to be. (It lived its first iteration as simply "on Balance"- the name change should indicate to you that a) running is important to me, and b) I like puns.). A few years later, Well Balanced Women came into life. (Again with the puns.). Its all quite fitting, actually. Pregnancy and gestation of a human arent all that different from building a business.. They both start with knowing absolutely nothing, requiring tremendous faith, and then developing and changing over time..

The linear inverted pendulum model focuses on the translational components of a legged robots dynamics. Derivation Both fixed and mobile robots are usually modeled as rigid bodies connected by actuated joints. The equation of motion for such a system are: \begin{equation*} \bfM(\bfq) \qdd + \qd^\top \bfC(\bfq) \qd + \bfg(\bfq) = \bfS^\top \bftau + \sum_{i=1}^N \bfJ_{C_i}^\top \bff_i, \end{equation*} where \(\bfq\) is the vector of actuated and unactuated coordinates. Actuated coordinates correspond to joint angles directly controlled by motors. Unactuated coordinates correspond to the six degrees of freedom for the position and orientation of the floating base (a frame attached to any of the robots bodies) with respect to the inertial fame. The vector \(\bfq\) is typically high-dimensional. Centroidal dynamics The first working assumption to simplify this model is (Assumption 1) that ...

Balance is very important, especially as we get older. People can fall when they lose their balance, sometimes with serious consequences.
As we age, our balance and equilibrium gradually get worse. This can result in seniors prone to losing their balance and falling. Vertigo (dizziness) is the feeling you get when you have the sensation as if you or the room are spinning. It has been reported that in the United States nearly one-third of seniors after the age of 65 have falls linked to balance problems and at age 75 and beyond nearly half of this group will suffer a fall secondary to balance problems. There is no preference…. Continue reading → ...

From the Foreword. The authors are to be commended for their comprehensive approach in dealing with a fairly frequently seen clinical entity that bedevils a large segment of clinicians providing care to the pediatric population. In fact, if truth be known, some aspects of balance disorders in children are just now beginning to be studied. This manual is exceptionally well organized. At outset it highlights all relevant information needed to understand balance in an overview fashion. Standardized evaluation of balance function in children has lagged behind such testing in adults. This manual does an admirable job of redressing this by providing an overview of the state of the art testing in the pediatric population. Virtually all of the clinical entities affecting balance in children are reviewed by a cross section of specialists who discuss issues relevant to diagnosis and treatment. The concept of central plasticity and its pivotal role in treatment of the pediatric population is dealt with in ...
