Recurrent eccentric exercise (EE) has been shown to increase skeletal muscle performance, specifically force production, and decrease susceptibility to subsequent re-injury via protective mechanisms, known as the repeated bout effect (RBE) [1,2]. Eccentric contraction during EE actively stretch musc...
The purpose of this study was to determine the detrimental effects of a high-fat/high-sucrose (HFS) diet on muscle integrity and the contractile properties of single myofibers, and whether prebiotic fibre supplementation (PFS) and moderate aerobic exercise can mitigate these detrimental effects. HFS...
The influence of orthotics on the kinematics of the trapeziometacarpal (TMC) and scaphotrapeziotrapezoidal (STT) joints during thumb and wrist movement were measured in healthy volunteers using a CT-based approach. Comparison of different types of orthoses show that prefabricated orthoses immobilize...
Current literature provides evidence that moving adjacent body segments can alter muscle activity, but there is a gap on the effects at the glenohumeral joint. The purpose of this study is to investigate differences in glenohumeral muscle activation elicited by altering torso angle during shoulder f...
Recently produced vehicles are equipped with functions for driver safety. The Lane Keeping Assistance (LKA) system prevents the vehicle from leaving the lane. However, the operation of the LKA system affects the driving comfort of the driver. In this study, we investigated the relationship between r...
Virtual reality was used to expose healthy younger and older adults to environments anticipated to challenge standing balance. Seven VR environments were compared to baseline standing. Center of pressure range in the anterior-posterior plane (measured by force plate) was significantly increased for ...
The effect of cerebellar transcranial direct current stimulation (c-tDCS) on online and offline learning of complex multi-joint movements is relatively unexplored. This study employed a two-session double-blind SHAM-controlled design to examine total, online, and offline learning effects of c-tDCS o...
Skeletal muscles are typically assumed to behave as single fibres scaled to larger sizes without considering the mechanical effects of greater tissue mass. While previous work has shown that larger muscle size and mass decreases the work and power output of contracting muscle, the metabolic conseque...
Cognitive load associated with dual-tasking while walking is known to affect balance and increase fall risk. The objective of this study was to quantify the effect of cell phone usage on head stability during walking.
In this presentation, Hilary Stellingwerff (2-time Olympian in 1500m) will share her experiences training during and after pregnancy in lead up to the Rio Olympics. She will present and discuss these assessment and changes from an athlete and mother’s perspective and hopefully provide a unique opp...
Range of motion (ROM) impairments occur in up to 77% of breast cancer survivors (BCS) [1]. This study defined the influence of time from treatment on ROM, specifically during activities of daily living (ADLs). Kinematic data of the torso and upper limbs were collected during maximal ROM and ADL (for...
The implant failure for large defects is usually induced by unfavorable stress distribution due to unsuitable structural design in mandible reconstruction. Topology optimization is usually applied to solve structural optimization under one loading condition and cannot be applied to a specific mandib...
Clinical and experimental locomotor learning is often done on treadmills, which are commonly equipped with handrails. However, the effects of holding handrails on locomotor learning are unknown. Here we study the effects of handrail holding on split-belt adaptation in four groups: 1) Holding side-mo...
The objective of this study was to assess the impact of a self-lacing footwear system with three conditions of increasing lace tension (compared to a control basketball shoe) on foot containment by measuring foot-shoe motion during cutting using high speed stereo radiography (HSSR). Two shoes were e...
Rotator cuff disease is a common cause of pain and dysfunction. Understanding the mechanism of rotator cuff injury is required for prevention and effective treatment. The effect of kinematics on rotator cuff pathology is not well understood — finite element modeling may be used to understand the m...
Because of the epidemiological incidence of Anterior Cruciate Ligament (ACL) injuries and the high reinjury rates that occur when returning back to sports, what criteria should be used to return the athletes to sports after ACL reconstruction is still an open issue. Neuromuscular risk factors have p...
Walking speed is one of the important factors in gait analysis. The purpose of the study is to examine the walking speed variation and biomechanical effects caused by the walking speed after wearing the Variable Stiffness Shoes (VSS). Twenty subjects were instructed to walk in three shod conditions,...
The purpose of this research study was to examine how people maintain static and dynamic postural control when performing volitional head movements. Fifteen healthy young adults participated; each was assigned to a Head Direction group: Yaw, Pitch, or Roll. Participants performed the Sensory Organiz...
