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 ...

Plantar fasciitis is a common running injury often resulting in alterations in training, but it is unknown if gait mechanics differ based on injury status. This study examined gait kinematics in runners with current plantar fasciitis, resolved plantar fasciitis, and no history of plantar fasciitis.

This study investigated whether prolonged and repetitive exercise stiffens the plantar soft tissue. Healthy early twenties female subjects with similar BMI but different majors (13 engineers and 13 ballerinas) were recruited. The plantar tissue thickness, peak pressure and force and pressure distrib...

Mobilisation is used for improving range of motion and reducing pain in patients with shoulder disorders. It is currently unclear what the underlying mechanisms of that technique are. This study aimed to assess the effect of inferior shoulder mobilisation on scapular and shoulder muscle activity, du...

A systematic review of the murine tibia axial compression model was carried out in order to explore the effect of static preload (SPL) on bone adaptation. SPL is a recently identified potential inhibitor of loading-induced bone adaptation [1]. Of 1766 initially identified references, 15 articles met...

The purposes of this study was to investigate the arch supporting effects of the Low-Dye taping with elastic tape on the healthy adults with pronated foot. Secondary, we also observed whether the supporting effect can last till the end of the exercise. Foot arch indices such as vertical navicular he...

This study provides a case series of five children with CP, examining the effect of tuned and non-tuned AFO-footwear combinations (AFO-FCs) on their gait. Walking with a tuned AFO-FC was found to produce improvements in several key gait parameters. However, the type of gait pattern demonstrated by t...

The effect of weighted backpack positions on lower limb joint while walking on a lateral inclined surface was investigated in this study. The joint angle, joint moment, stance force and lower limb electromyography of seven heathy male subjects, while walking on a lateral inclined surface wearing no ...

We are hypothesizing that when humans walk on the sloped surfaces, the foot placement is dependent on the slope angle and walking speed. In this paper, to have a better understanding of the relationship between the step length to the slope angle and walking speed, we performed a statistical analysis...

The physical stress of clinical practice is an occupational risk factor for developing musculoskeletal disorders (MSDs) in dental hygienists. The utilization of dental magnification loupes shows promise in allowing the practitioner to maintain a neutral posture, enhancing quality of care and a reduc...

Stroke is an acute cerebrovascular disease that might cause severe motor function impairment of upper limbs (UL) [1]. Although UL motor function can be improved through effective rehabilitation, deficiencies in fine motor (FM) skills often remain even after patients are discharged from rehabilitatio...

This study investigates the differences in head impact exposure (HIE) for the striking player versus the struck player during tackling events in youth football. Head impact data was collected for six youth football games over three seasons using the Head Impact Telemetry (HIT) System to measure magn...

Resisted sprint training is a traditional way to train the elite athletes. According to the leading joint hypothesis, adding mass on the shanks is seen as a more targeted way to strengthen the special muscles. The aim of this study is to examine the influence of this training method on the kinematic...

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 aim of this study was to use computational simulation to investigate the effect of orthopaedic plate stiffness and its thickness, on the mechanical response of the fracture site within an osteoporotic tibia, and to determine the optimised conditions in favour of the bone healing process.

Protective arm reactions were evoked in 12 younger adults to determine the effect of delaying deployment of a protective response. Participants were supported in a forward-leaning position that was released at an unpredictable time. Upon release, participants rapidly oriented the arms to prevent col...

This study seeks to investigate the effect of verbal instruction (VI) on muscle activity, with and without muscular pre-exhaustion (PE) on the temporal domain of the surface electromyographic activity (sEMG). Given that PE and VI seem to modify the muscle sEMG, twenty men performed four randomized-s...

The present study compared the effect of tail/head wind on two reference jumps with different aerodynamic properties (CL and CD) during the flight phase. The computer simulation showed that the wind scenarios used in the present study had a reverse effect on the jumps. Proper wind conditions at the ...
