Stair falls are a major problem for older people. The present study: a) applied a novel multivariate approach to characterize the overall stair behaviour while ascending and descending stairs and b) investigated whether the selected stepping behaviour was maintained irrespective of step dimensions. ...

In response to musculoskeletal injury risk consequences of shifting global body composition demographics, this study explored relationships between body composition and strength. Negative correlations between strength normalized by body weight and body composition suggest current assumptions may pro...

The relative muscle volume is the critical parameter to estimate the contribution of individual muscle on joint torque. Because muscle hypertrophy is prominent in the fast than slow twitch muscle, it is hypothesized that the relative muscle volume of triceps surae may vary among subjects according t...

Quantitative measures related to mechanical strength of the anterior cruciate ligament (ACL) graft are needed for timely return-to-sports decisions after the ACL reconstruction surgery (ACLR). Ultra-short echo-time (UTE)-T2* magnetic resonance imaging (MRI) was used to study structural changes in gr...

This study examined differences in hip, knee and ankle joint kinematics of a vertical drop jump (VDJ) task between youth with Juvenile Idiopathic Arthritis (JIA) and their age and sex matched typically developing (TD) peers. Youth with JIA performed the VDJ with significantly less knee flexion, redu...

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...

High-speed biplanar videoradiography (HSBV) enables new insights on the in-vivo dynamic motions of the pathological spine. Variations in the defined segment specific anatomical coordinate systems (ACS) likely influence repeatability of vertebral kinematics. This study investigated the effects of rep...

Healthy tibio-femoral kinematics are controversially discussed in the literature. In this study, 10 healthy subjects were assessed throughout dynamic functional gait activities using a moving fluoroscope to establish physiological healthy knee kinematics. Significantly larger range of anterior-poste...

A framework is proposed to develop an inhomogeneous Finite-Element (FE) model of a human proximal humerus fracture (PHF) with an osteosynthesis device in order to characterize the overall stiffness and load to failure properties under physiological-like loading/test conditions. An experimental set-u...

The purpose of this study is to investigate for the effect of functional compression tights (FCT) using a biomechanical method. Eighteen limbs of 10 healthy male participants were included. Participants were required to perform straight-line walking trials at usual walking speed. A three-dimensional...

We investigated the effect of movement speed and load on motor unit firing behaviour during repeated flexion/extension contractions of the Biceps Brachii. At all speeds and loads, greater motor unit firing rates were observed during the concentric vs. eccentric phases of the movement. However, diffe...

Decades of in vivo exogenous skeletal loading studies have identified numerous loading parameters associated with enhanced osteogenic responses while also revealing signalling pathways essential for mechanostransduction. However, the translation of these insights into effective exercise intervention...

Old vs young adults had lower ankle plantarflexor but not hip extensor strength. They also showed biomechanical plasticity (BP) through higher hip/ankle ratios of peak joint torques & powers in level & inclined walking. BP ratios were not correlated however with the relative strengths of hip vs ankl...
