We compared the effects of shoe midsole cushioning on the knee compression impulse during the first 50 ms of ground contact between midfoot (MF) and rearfoot (RF) runners, while controlling for the effects of: knee joint angle at contact, knee joint stiffness, shank velocity at contact, pelvis horiz...
The study used the quantified assessment, feasible flexible region (Figure 1), to establish the relationship between the center of mass (COM) and base of support BOS). Eight subjects with MS were recruited. An 8-camera motion capture system (Vicon, UK) was used to collect their full-body kinematics ...
A 16-week progressive foot muscle specific intervention program decreased some parameters associated with non-contact anterior cruciate ligament (ACL) and lateral ankle sprain (LAS) injury mechanisms. Changes in inter-foot and foot-shank segmental relationships were also observed.
Fatigue decreases the performance and affects the postural control, but its after effect duration is not clear yet. This study aimed to investigate the effect of a specific fatigue protocol for handball athletes in the postural control. Handball athletes stood quietly on the force plate for 30 s. In...
The purpose of this study was to measure the effects of a menthol-based topical analgesic on delayed onset muscle soreness (DOMS) induced changes to running biomechanics and pain. We measured perceived pain utilizing a comparative pain scale (CPS), and pain pressure threshold (PPT). Kinematics were ...
A delivery van ingress strategy using the A-pillar handhold instead of the steering wheel as hand support reduces reaction forces at the intermediate entrance step by approx. 17 %. The applied force at handhold or steering wheel remained comparable for both movement patterns. Therefore, a strategy u...
The efficacy of external ankle braces to protect against sudden inversion sprain has yet to be determined, while taking into account the possible placebo effect of brace application. In this controlled study, we assessed kinematics using both actively protecting and placebo braces in subjects with a...
Ankle-foot orthosis (AFO) properties, particularly stiffness, can affect gait kinematics. Because AFOs are made from viscoelastic materials, the effects of stiffness may vary at different walking speeds. However, the impact of ankle flexion speed on AFO stiffness has not been thoroughly investigated...
Sustained postero-lateral glide at the glenohumeral joint is a manual therapy technique used for treating patients with shoulder pain. The aim of this study was to assess the effect of sustained glide on scapular muscle activity ratio. We used surface electromyography to monitor activity of three sc...
Why do cyclists sway their bicycle from side to side when riding out of the saddle? We tested the theory that lateral bicycle sway may decrease the work performed by the rider on their center of mass (CoM) and also impact the contribution of power at the hip, knee and ankle during standing cycling. ...
According to the American College of Rheumatology, there are approximately 14 million people suffering from symptomatic knee Osteoarthritis (OA), two million of those being under the age of 45 [1]. Usual treatments for OA consist of total knee replacement, and use of knee orthosis [2]. However, the ...
A large dynamic joint stiffness (DJS) has been associated with skeletal injury, while a lower DJS has been associated with an increase in soft tissue injury [1]. Increased Co-contraction indices (CCI) have been linked to increased joint contact forces [2]. DJS and CCI were calculated to determine ho...
postural control during tasks of quiet standing, especially in the presence of sensorial deficit. Dance interventions have been shown to have a positive impact on postural control. Thus, the aim of the current project was to evaluate the effects of a dance intervention on postural control in individ...
Counter-movement jump height along with several kinetic and kinematic measures, decreased following an acute fatigue protocol. However, single-subject analysis revealed that four participants jumped higher following the fatigue protocol as a result of generating greater concentric impulse.
Cortical remodeling was shown to be affected by the type and magnitude of physiological stress.¶ This study investigated the effect of compression vs. tension loading on the morphology, mineral¶ content and stiffness of secondary osteonal bone in the proximal humerus of white-tailed deer.¶ Thirty...
The effect of diabetes on the ability of older adults to respond to external perturbations is not well documented. The purpose of this study was to determine if stepping threshold (ST) could be quantified in a clinical setting in older adults with diabetes and if it provided unique information regar...
