TY - JOUR. T1 - Influence of biomechanical factors on substructure of pointing movements. AU - Dounskaia, Natalia. AU - Wisleder, Deric. AU - Johnson, Travis. N1 - Funding Information: Acknowledgements The study was supported by NSF grant BCS 0213653 awarded to Dr. Natalia Dounskaia.. PY - 2005/7. Y1 - 2005/7. N2 - Irregularities in the velocity profile near the end of pointing movements have been interpreted as corrective submovements whose purpose is to provide accuracy of pointing to the target. The purpose of the present study was to investigate whether two additional factors related to biomechanical properties of the arm also cause submovements. First, motion termination and stabilization of the limb in the final position required by a discrete pointing task may contribute to submovements. Second, inaccurate regulation of interactive torque at the joints may also cause submovements. To investigate the contributions of these two biomechanical factors and the traditionally considered factor ...

Several investigators have suggested the presence of a link between Chronic Low Back Pain (CLBP) and lower limbs kinematics that can contribute to functional limitations and disability. Moreover, CLBP has been connected to postural and structural asymmetry. Understanding the movement pattern of lower extremities and its asymmetry during walking can provide a basis for examination and rehabilitation in people with CLBP. The present study focuses on lower limbs kinematics in individuals with CLBP during walking. Three-dimensional movements of the pelvic, hip, knee and ankle joints were tracked using a seven-camera Qualysis motion capture system. Functional dada analysis (FDA) was applied for the statistical analysis of pelvic and lower limbs motion patterns in 40 participants (20 CLBP and 20 controls). The CLBP group showed significantly different hip motion pattern in the transvers plane, altered knee and ankle motion pattern in the sagittal plane on the dominant side and different hip motion ...

We evaluated the corneal biomechanical properties in a population of healthy children in China. As far as we know, this is the first report of quantitative assessment of the corneal biomechanics in children population using CST. We used the newly updated CST software, which provided two more parameters (A1DA and A2DA) than previous versions. This helped to measure corneal deformation more comprehensively. We also assessed the symmetry of corneal biomechanics between the both eyes and found obviously interocular symmetry in SE, CCT, IOP, and corneal biomechanics in healthy children eyes. We also found that several CST biomechanical parameters in children are modified by CCT and IOP, while age, SE, and sex exert little influence on the CST measurements in this population.. Our observations of interocular symmetric biometry were consistent with previous studies [19-21]. Using ORA, Zheng et al. [22] demonstrated an obvious symmetry of CH and CRF in bilateral rabbit corneas. We also identified two ...

AU - Yanai, Toshimasa. AU - Kawakami, Yasuo. PY - 2015/4/1. Y1 - 2015/4/1. N2 - Aim: The purpose of this study was to examine kinematic differences between faster and slower sprinters during the acceleration phase of sprint running. Methods: Nineteen collegiate sprinters were divided into FAST (N.=9) and SLOW (N.=10) groups, based on their best 100 m race times. A two-dimensional videographic technique was used to record the side views of 40 m sprint performances using four high-speed digital camcorders. Using the recorded images, kinematic variables such as contact time, flight time, horizontal velocity, and horizontal acceleration were determined from the 1st step to the 19th step. A two-way repeated measures ANOVA (two groups of 10 steps each) with a Tukey post-hoc test was used to analyze the obtained data. ...

During walking older adults gait is slower, they take shorter steps, and rely less on ankle and more on knee and hip joint moments and powers compared to young adults. Previous studies have suggested that walking speed and step length are confounds that affect joint moments and powers. Our purpose was to examine the effects of walking speed and step length manipulation on net joint moments and powers in young and older adults. Sixteen young and 18 older adults completed walking trials at three speeds under three step length conditions as marker position and force platform data were captured synchronously. Net joint moments were quantified using inverse dynamics and were subsequently used to compute net joint powers. Average extensor moments at each joint during the stance phase were then computed. Older adults displayed greater knee extensor moment compared to young adults. Older adults showed trends (p | .10) of having lower ankle and higher hip moments, but these differences were not statistically

Ground reaction forces (GRF), knee flexion angles, angular velocities and joint powers are unknown at large landing heights, which are infeasible for laboratory testing. However, this information is important for understanding lower extremity injury mechanisms. We sought to determine regression relationships of landing height with these parameters during landing so as to facilitate estimation of these parameters at large landing heights. Five healthy male subjects performed landing tasks from heights of 0.15-1.05 m onto a force-plate. Motion capture system was used to obtain knee flexion angles during landing via passive markers placed on the lower body. An iterative regression model, involving simple linear/exponential/natural logarithmic functions, was used to fit regression equations to experimental data. Peak GRF followed an exponential regression relationship (R2 = 0.90-0.99, p , 0.001; power = 0.987-0.998). Peak GRF slope and impulse also had an exponential relationship (R2 = 0.90-0.96, p ...

TY - JOUR. T1 - An examination of kinematic variability of motion analysis in sprint hurdles. AU - Salo, Aki. AU - Grimshaw, Paul N.. PY - 1998/5. Y1 - 1998/5. N2 - Eight trials each of 7 athletes (4 women and 3 men) were videotaped and digitized in order to investigate the variation sources and kinematic variability of video motion analysis in sprint hurdles. Mean coefficients of variation (CVs) of individuals ranged from 1.0 to 92.2% for women and from 1.2 to 209.7% for men. There were 15 and 14 variables, respectively, in which mean CVs revealed less than 5% variation. In redigitizing, CVs revealed ,1.0% for 12 variables for the womens trials and 10 variables for the mens trials. These results, together with variance components (between-subjects, within-subject, and redigitizing), showed that one operator and the analysis system together produced repeatable values for most of the variables. The most repeatable variables by this combination were displacement variables. However, further data ...

This paper introduces an easiest method for finding out the transfer function of complex mechanical systems with multiinput and multi-output. But at a time, one input and one output is significant. The method is an extension of inspection method of network solution by makes use of KVL. In the beginning step the available mechanical system has to be transformed into Laplace domain with associated differential co-efficient if any. Determine the Order of the system by considering the No. of masses/moment of inertia available in the system in turn determines the order of the transfer function matrix of the system. If once the transfer function matrix is formed, any combination of input and output can be selected to find out the transfer function by using Crammers Rule. The method is a perfect fit one, easiest than statespace approach and fastest one for such systems states having trivial states.. Keywords: Transfer Function, Multi-input Multi-output systems, KVL-Kirchhoffs Voltage Law, Laplace ...

Introduction: Kinetic, kinematic and electromyographic activity of the lower limb have been shown to be influenced by various footwear-generated biomechanical manipulations (e.g. soles. Insoles, orthoses). A novel biomechanical device comprising four modular elements attached onto foot-worn platforms was recently developed. Each element can be individually calibrated (Position, convexity, height and resilience) to induce a specific biomechanical challenge.. Objectives: The aim of this study is to evaluate the influence of specific biomechanical challenges on Kinetics, kinematics and electromyographic activity of the lower limb.. Design: Prospective, case control Setting: Motion analyses will be conducted during level walking with (1) a three-dimensional motion analysis system and (2) ground reaction force analysis using force platforms (3) Electro-Myography system. Each subject will be examined in 16 different settings of the biomechanical system ...

Despite the continuing research effort, data regarding the material properties and biomechanical parameters of spinal elements, particularly the ligaments, remains sparse.. The ligaments, discs, and vertebrae of the human spinal column were tested for their biomechanical strength. 65 samples of human vertebrae were tested in direct axial compression to failure in an M.T.S. testing machine. Average values of force at failure ranged from 2587N in the cervical spine to 4590N in the lumbar spine. Average values of stress at failure decreased from 7.9N/mm² in the cervical spine to 2.8N/mm² in the lumbar spine. Mean values of engineering strain at failure ranged from 24.4% to 33.9%.. Overall, 33 samples of the human intervertebral disc were tested in direct axial tension to failure. Average values of force at failure ranged from 592N in the cervical spine to 1254N in the lumbar spine. Deformations to failure ranged from 8.9mm to 11.1mm. Mean values of stiffness of the disc increased from 64.2N/mm in ...

The aim of this study was to provide a comprehensive analysis of key biomechanical variables in race walking through the analysis of elite athletes in both competitive and laboratory settings. Video data from two 3CCD camcorders of athletes competing over 10 km (juniors only), 20 km, and 50 km were collected at three international competitions. For the 20 km and 50 km events, multiple recordings were made to identify if kinematic changes occurred. In addition, synchronised high-speed video, electromyography and ground reaction force data were collected of 20 elite race walkers in a laboratory setting and combined to calculate joint moments, power and work. The key discriminants with regard to better performances were long step lengths and high cadences, and the contribution made by flight distance to step length (approximately 13%) was particularly important, regardless of race distance or age category. Step length ratio was a better predictor of optimum step length than absolute values and a ...

Pre-injury control data were collected on two separate days before the nerve injury surgery was performed. Post-injury data were collected 1-month post-surgery during the muscle paralytic stage and at 14 months post-surgery during the muscle self-reinnervated stage. The self-reinnervated stage data reported here reflect the 14-month post-injury stage for all but one cat,which did not complete the 14-month collection. Instead, 9-month self-reinnervated stage data were successfully collected and are reported for this individual. During all data collection trials, the cats walked on our treadmill at 0.8 m s-1 until a steady gait was observed. Three-dimensional (3-D) marker positions on the left hindlimb were recorded at 125 Hz for 16 s with a two-camera motion capture system (Peak Performance Technologies, Denver, CO, USA) and saved to a computer for later analysis. Animals were allowed to rest for at least 2-5 min between the two to four trials collected for each day of collection. A typical 16-s ...

The main biomechanical function of the knee meniscus is to enlarge the contact area of the tibiofemoral joint leading to a reduction in articular cartilage contact stress. The meniscal attachments are essential for converting the axial load into circumferential tension in the meniscal periphery. Consequently, meniscal substitutes need sufficient anchorage to the tibial plateau to adequately restore the biomechanical function of a replaced meniscus. Therefore the aim of the present study was to investigate the loads acting on the meniscotibial attachments under various joint loads ...

Leg stiffness is often computed from ground reaction force (GRF) registrations of vertical hops to estimate the force-resisting capacity of the lower-extremity during ground contact, with leg stiffness values incorporated in a spring-mass model to describe human motion. Individual biomechanical characteristics, including leg stiffness, were investigated in 40 healthy males. Our aim is to report and discuss the use of 13 different computational methods for evaluating leg stiffness from a double-legged repetitive hopping task, using only GRF registrations. Four approximations for the velocity integration constant were combined with three mathematical expressions, giving 12 methods for computing stiffness using double integrations. One frequency-based method that considered ground contact times was also trialled. The 13 methods thus defined were used to compute stiffness in four extreme cases, which were the stiffest, and most compliant, consistent and variable subjects. All methods provided ...

Biomechanical variables included (1) whole-body ...

Abstract: Since 1996, when the first report of sex differences in neuromuscular function appeared in the literature with the aim of understanding why physically active females are at greater risk of injuring the ACL than their male counterparts, many authors have reported on sex differences in neuromuscular and biomechanical function. Based on this collective literature, clear sex differences in muscle activation and movement patterns have been identified, leading to the focus on neuromuscular and biomechanical factors as the key reasons for the sex differences in ACL injury rates. In turn, prevention programs have been developed to reduce dynamic knee loading through neuromuscular training.. Editorial.

A device for sensing a state change of a mechanical system, comprises at least one sound emitter (E), a receiver (R) as well as an electronic circuit (4) which allows to compare the received sound signal with reference values. The state of the mechanical system, such as the existence or the absence of contact among parts, is monitored by the processing of the signals corresponding to the emitted and received sound signals with the aim to allow to recognize the monitored state by the difference between the received signals and reference values. The sensing device may be used to monitor a number of variables such as contact, location, orientation, etc. of the mechanical parts by the same sensors there where traditionally different kinds of sensors were traditionally needed.

N2 - In this work, we explore the molecular mechanisms by which local mechanical properties (e.g., rigidity) of the extracellular matrix (ECM) cooperates with soluble cues to regulate lineage commitment of human mesenchymal stem cells (hMSCs). We have established different micropost array substrates that can definitively decouple matrix rigidity from other properties including adhesiveness. We applied these substrates to investigate the influences of matrix rigidity on cell adhesion, cytoskeleton assembly/contractility, cell spreading, and proliferation. We further show that matrix rigidity regulates commitment of hMSCs to either adipogenic or osteogenic fate: soft matrix facilitates adipogenic differentiation while stiff matrix proves osteogenic.. AB - In this work, ...

Currently, rigid fixation systems are the gold standard for degenerative disk disease treatment. Dynamic fixation systems have been proposed as alternatives for the treatment of a variety of spinal disorders. These systems address the main drawbacks of traditional rigid fixation systems, such as adjacent segment degeneration and instrumentation failure. Pedicle-screw-based dynamic stabilization (PDS) is one type of these alternative systems. The aim of this study was to simulate the biomechanical effect of a novel posterior dynamic stabilization system, which is comprised of dynamic (hinged) screws interconnected with a coiled, spring-based dynamic rod (DSDR), and compare it to semirigid (DSRR and RSRR) and rigid stabilization (RSRR) systems. A validated finite element (FE) model of L1-S1 was used to quantify the biomechanical parameters of the spine, such as range of motion, intradiskal pressure, stresses and facet loads after single-level instrumentation with different posterior stabilization ...

Altered gait biomechanics associated with pediatric obesity may increase the risk of musculoskeletal injury/pathology during physical activity and/or diminish a childs ability to engage in sufficient physical activity. The biomechanical mechanisms responsible for the altered gait in obese children are not well understood, particularly as they relate to increases in adipose tissue. The purpose of this study was to investigate the role of adiposity (i.e. body fat percentage, BF%) on lower extremity kinematics, muscle force requirements and their individual contributions to the acceleration of the center of mass (COM) during walking. We scaled a musculoskeletal model to the anthropometrics of each participant (n=14, 8-12 years old, BF%: 16-41%) and generated dynamic simulations of walking to predict muscle forces and their contributions to the acceleration of the COM. Muscle force output was normalized to muscle mass. BF% was correlated with average knee flexion angle during stance (r=−0.54) and ...

Although Kendalls structural approach to postural assessment provides a biomechanical assessment of the musculoskeletal system, the late Vladimir Janda, MD, saw postural assessment as a functional impression of the status of the sensorimotor system. According to Janda, the sensorimotor system is 1 functional unit comprised of the afferent sensory system and the efferent motor system; 2 systems that cannot be considered to function independent of each other.34 He noted that changes in muscle tension are the first response of the system to nociception. By combining static biomechanical assessment popularized by Kendall with his observation of muscle function, Janda was able to form an early observational description of the possible cause of the patients musculoskeletal pain from a neurological perspective.34 ...

Blood vessels are exposed to multiple mechanical forces that are exerted on the vessel wall (radial, circumferential and longitudinal forces) or on the endothelial surface (shear stress). The stresses and strains experienced by arteries influence the initiation of atherosclerotic lesions, which develop at regions of arteries that are exposed to complex blood flow. In addition, plaque progression and eventually plaque rupture is influenced by a complex interaction between biological and mechanical factors-mechanical forces regulate the cellular and molecular composition of plaques and, conversely, the composition of plaques determines their ability to withstand mechanical load. A deeper understanding of these interactions is essential for designing new therapeutic strategies to prevent lesion development and promote plaque stabilization. Moreover, integrating clinical imaging techniques with finite element modelling techniques allows for detailed examination of local morphological and biomechanical
