A previous study determined optimised glenosphere placement on reverse total shoulder arthroplasty (RTSA) in order to improve impingement free range of motion. The current study has evaluated the effect of this optimised placement on micromotion at the bone-implant interface using a finite element s...
The mechanisms by which fear of falling (FoF) increases fall risk are not well understood. While increased arousal and anxiety in response to perceived postural threat is known to affect postural control during standing and following non-stepping perturbations, the effect on stepping responses remai...
A prosthetic shock-absorbing pylon (SAP) attenuates impact forces to dissipate shock in individuals with amputation. However, it is unclear how a SAP and their spring stiffness affect the mechanical work done by the prosthetic limb. We observed that SAP spring stiffness had a speed-dependent effect ...
Cervical myelopathy patients are less stable than a control group as determined by analysis of postural stability, through measures on center of pressure, and dynamic stability, through measures of angular momentum regulation. Stability is improved by spinal decompression and stabilization surgery.
The material properties of the intact human liver using unconfined compression with varying strain rates were measured in this study. The liver modulus was not strain rate dependent between 1%/s and 25%/s. Failure stress increased by 20% and failure strain increased by 46% when the strain rate was i...
We studied the effects of bilateral triple arthrodesis (BTA) on the strength of soleus and peroneus brevis muscles, and on knee flexion/extension during gait using EMG and a kinematic model of the lower limb. We found that the maximum knee flexion and extension was reduced in all patients compared t...
Stability in flight is essential for performance and safety in ski jumping. However, the effect of vertical axial wind on the flight stability in ski jumping remains unknown. In this study, the effect of vertical axial wind on the flight stability was analyzed by computational fluid dynamics (CFD) s...
Low back pain (LBP) is the most common, and disabling musculoskeletal disorder worldwide, with posture being a modifiable risk factor for LBP. The aim of the study was to assess the effectiveness of a lumbopelvic postural feedback device for changing postural behaviour in a group of healthcare worke...
Temporomandibular joint osteoarthritis (TMJ-OA) has considerable prevalence with 13-58.3% of the population. The signs and symptoms of TMJ-OA include joint pain, clicking and crepitus, limited mouth opening, mandibular movement dysfunction, as well as facial esthetic changes, which cause the limited...
Inertial measurement units (IMUs) were used to quantify the effects of military clothing and individual equipment (CIE) on both expert and novice marksmen. The focus was to capture the differing movement strategies used to mitigate the effects of CIE on marksmanship performance. A primary hypothesis...
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 ...
Muscle fatigue of upper extremity with previous shoulder injury in throwing and hitting task, which relates to both release force control and the dynamic stability control, is common in training program and competition occasions. After a fatiguing protocol, we found changes in shoulder and elbow max...
Cam femoroacetabular impingement (FAI) is a common cause of hip injuries, instability, and early joint degeneration. Early surgical intervention attempts to improve hip function, by restoring mobility and alleviating symptoms, but it is unclear how the morphology and capsule influence joint mechanic...
Indoor rock-climbing falls onto padded and unpadded surfaces are a common source of injuries. This research provides experimental data quantifying the effects of foam thickness and impact velocity in padded falls onto the buttocks using human volunteers and an anthropomorphic test device (ATD).
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...
