How localized fatigue at different muscles affects whole-body coordination during a repetitive task is poorly understood. We studied 17 participants who completed a repetitive task before and after fatigue was induced at either shoulder, elbow or lower back. Results show that fatigue location differ...
Due to changes in segmental volume and mass during weight loss, the role of body weight per se on gait characteristics in obesity is poorly understood. We measured lower extremity EMG activity and sagittal plane joint angles in obese women (N=3) walking on a positive-pressure treadmill (0 and 25% bo...
Skeletal muscle passive elastic modulus is an important material property which affects muscle and joint mechanics; yet, it is still poorly understood. Both intrafibrillar (primarily titin) and extrafibrillar (basement membrane) structures are suggested to bear passive tension. Here, we applied the ...
In this study, we developed a prototype of the anterior cervical plate (ACP) with blocking pin made of shape memory alloy to facilitate insertion and removal of screws and conducted a mechanical strength test and finite element (FE) analysis to evaluate biomechanical stability. The test results show...
There are many factors that can influence concussion recovery, including the sex of the patient, thus necessitating sex-specific analyses. Few studies have investigated concussion recovery between sexes using objective outcomes as a measure of recovery. We examined the association between sex and re...
Changes in sagittal knee moments and patellofemoral contact force have been linked to the risk of patellofemoral pain(PFP). Previous studies proved that there were different loading patterns of knee joint with different foot strike patterns and surface cushioning conditions. Currently, few studies d...
Despite the generally accepted importance of form & force closure mechanisms in sacroiliac joint (SIJ) biomechanics, very little is known about SIJ form and orientation, and the relationship between both. This study describes the sagittal orientation of the SIJ relative to gravity, and defines its c...
The objective of our study is to develop an XFEM model of cancellous bone specimen in 3D that is capable of accurately predicting the onset and propagation of cracks under mechanical loading. In order to do so, the micro-CT scan data of cancellous bone was converted into 3D geometry. Material proper...
It is very important to clarify the differences in full body joint kinematics between elite endurance runners (elite runners) and novice runners for developing gait retraining regimes. This study collected motion capture data of runners and performed principal component analysis (PCA) for the data. ...
Fragile X Syndrome (FXS) is a genetic condition, mainly characterized by intellectual disability and behavioural problems. In subjects with this syndrome, delays in the acquisition of the main stages of psychomotor development are commonly observed. This project aims to investigate associations betw...
Twenty-one CPR-certified participants performed six-minutes of CPR on a training manikin in four positions. Electromyography (EMG) of nine muscles, kinematics of the training manikin, and kinetic data at the hands of the rescuer were collected. There was no difference in the rate of decrease of ches...
Upon completion of a treadmill-based running retraining that focused on promoting a midfoot strike landing, reduced foot-strike angle and vertical instantaneous loading rates were observed in habitual rearfoot strike runners. We sought to measure whether these modified gait mechanics could be transf...
Traditional occupational biomechanics models of lifting use body posture and hand load to predict L5/S1 compression force estimates. A novel hybrid Bayesian network implementation of a static lifting model has been developed that incorporates disc injury status as well. However, it is unclear how se...
We assessed the accuracy of non-rigid image registration algorithms to quantify the three-dimensional deformation of the human medial gastrocnemius muscle from MRI scans of the muscle at rest and during isometric contractions at 10% and 20% of maximum voluntary isometric plantarflexion torque. Demon...
The use of bracing is a cost-effective and non-invasive treatment that provides pain relief without side effects with respect to knee osteoarthritis. In this study, a model with knee osteoarthritis combined with a finite element analysis model and a musculoskeletal model was constructed. This study ...
Muscle fibres consume metabolic energy to deliver force and do mechanical work. Less well characterized is a separate metabolic cost for cyclic force production, that is not included in current models for metabolic cost. We therefore characterized the metabolic cost for cyclic muscle force, hypothes...
This study analyzed the electromyography (EMG) activity of masseter and anterior temporalis muscles during chewing in 2 different posture conditions: natural head posture (NHP) and deliberate forward head posture (FHP) in healthy individuals; and to compare EMG activity between subjects based on the...
Evaluating what biomechanical changes influence the incidence of low back pain (LBP) in servicemembers with an amputation is a multifactorial issue. The goal of this study was to examine the biomechanical contributions in patients that self-report LBP and compare to patients with amputation who do n...
Functional data analysis (FDA) provides a powerful alternative to traditional digital filtering for analysing time-series data. In this study, FDA applied to repeated throwing trials facilitates comparison of curve shapes and key features.
Current methods for quantifying gait improvement in idiopathic normal pressure hydrocephalus (iNPH) are subjective and incomplete. This study demonstrates that patients with iNPH who have undergone ventricular peritoneal (VP) shunt placement demonstrate improvements in gait but still are impaired in...
This study examined the effect of heel-toe drop (HTD) on lower extremity kinematic and kinetics change when walking uphill. Ten healthy males walked uphill in identical shoes with varying HTD (0-mm, 15-mm and 30-mm). The present results revealed that participants with 30-mm HTD displayed significant...
Reaching overhead is a challenging task, especially for older adults, specifically because many people adopt unstable stances that lead to falls. This study investigates the effect of 3 factors on postural stability during an overhead forward reaching task: footwear, stance, and foot contact. Result...
A new energy storage and return insole has been developed with the goal of reducing musculoskeletal injuries by decreasing impact loads at heel strike while also assisting gait by releasing stored elastic energy during toe off. This pilot study analysed a single subject walking on an instrumented tr...
A major challenge in neuromechanics, particularly relevant to human health, is linking muscle-tendon (MT) morphology to proprioception. In anesthetized rats, we recorded intra-axonal sensory signals from active MT contractions. To modify the functional morphology, we physically added in-series sprin...
The custom of Bound foot among Chinese females had been practiced for over a thousand years, which was prohibited since early 20th century. This study recruited elderly Chinese females with bound feet and normal feet. Gait analysis were performed, and results from kinematics and plantar pressure tes...
Forward positioned head mounted technologies are becoming increasingly prevalent. This study assessed the effect of added forward positioned mass on upper neck extensor (UNE) and sternocleidomastoid (SCM) activity during reciprocal scanning. Results showed that UNE activity significantly increased w...
Multiple linear regressions were conducted to determine which kinematic and temporospatial variables best predict reduction in knee abduction moment (KAM) during gait modification (GM). Only varus knee angle and stride width predicted KAM reduction in GMs. These results demonstrate that factors asid...
The Functional movement screen (FMS) is an assessment tool for identifying physical weaknesses and asymmetries prevention potential injury. There has been plenty of FMS documents regarding to many sports. However, there are few FMS documents been conducted for baseball. Therefore, the purposes of th...
Individuals with bipolar disorder (BPD) exhibit gait abnormalities during symptomatic phases, but whether gait patterns are affected during asymptomatic phase is not known. Accordingly, this study aimed to describe gait patterns in asymptomatic individuals with BPD (n=14) as compared to healthy cont...
