Sensory feedback may be manipulated during a stretching intervention by the addition of roller-ball massage. This added feedback can result in a larger increase in range of motion than stretching alone, and may influence motor neuron excitability of the involved muscles.

The structure-function relationships in human tibial cartilage are not known. We combined fibril-reinforced poroelastic modelling with quantitative microscopy and histology to interpret structure-function relationships of human tibial cartilage. Our findings suggest that the loss of collagen pretens...

In order to better understand the biomechanics of stumbling and inform fall prevention strategies, seven individuals were tripped at a range of different times during leg swing. Kinematics and kinetics of their recoveries were analyzed. We identified the region in swing phase that elicited the most ...

This study investigated the type and number of haptic feedbacks that would yield better subject perceived accuracy during walking and running. Findings suggested staggered haptic feedback would lead to higher accuracy than continuous feedback especially when more than two motors were used.

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the ...

Regular papers should present novel perspectives within the general scope of the conference. Short papers (Work-in-Progress) are an opportunity to present preliminary or interim results. Posters are intended for ongoing research projects, concrete realizations, or industrial applications/projects pr...

Daily use of a manual wheelchair (MWC) has been identified as a potential source of shoulder pain in individuals with a spinal cord injury (SCI). Compression of the rotator cuff soft tissue beneath the coracoacromial (CA) arch is hypothesized to contribute to this pain. This study aimed to determine...

External cueing without variability fails to address the variable patterns typically observed in healthy gait, and rehabilitation goals are depending on the degree of synchronization. The ability to synchronize could be improved when coupling systems match in their time-based statistical properties....

While laboratory studies provide a rich literature on cognitive and physical performance under strenuous conditions that simulate some of the mission relevant conditions Soldiers are asked to perform, there is additionally a need to assess relevant biomechanical, physiological and cognitive metrics ...

The aim of the synthetic turf with underlaid shock pad is to provide additional impact absorption for the players. For this study, twelve active and healthy recreational male athletes performed 60 cm drop landing with a controlled landing style on five surfaces: a regular surface (force platform), a...

Previously developed structural finite element models of trabecular bone adaptation have used randomised networks of truss elements, resulting in high nodal connectivity (the number of structural elements connecting to each node). With element level adaptation nodal connectivity can reduce but remai...

Frozen and thinned bovine pericardium (BP) is a candidate transcatheter aortic valve (TAV) leaflet biomaterial for smaller-profile devices due to their reduced thickness now, however, their mechanical and structural properties still need to be to be fully test. In order to better understand their me...

This disposable production acceptance record examines how a small polar observatory classifies archival measurements during seasonal handover. A fictional instrument registers violet sky samples beside an amber calibration tile. Each observation receives a stable reference before reviewers compare i...

Inertial measurement units (IMU) are used to calculate joint kinematics. This study demonstrates that subject-specific calibration movements based on a patient’s function and ability including limited range of motion and speed are sufficient for defining body segment coordinate systems at the pelv...

In many countries, at least until relatively recently when stock ownership has democratised and isn't only for "the rich", real estate has been the go to investment. It paid more than cash and bonds at least, and seemed to only go up. Added to that, if you look at real estate returns in the last hun...

Surface and fine-wire electromyography activity of flexor hallucis longus, soleus, medial and lateral gastrocnemius and tibialis anterior muscles was measured simultaneously during walking at four different speeds to examine whether signals recorded with the two methods exhibit similar signal charac...

When evaluation cognition, there is a certain complexity surrounding electroencephalographic (EEG) recordings, which would greatly benefit from being supplemented by secondary recordings, such as those from a force platform. Currently, there is also a lack of evidence supporting the need to implemen...

The follow through phase of volleyball hitting can cause shoulder injuries like rotator cuff tears, which is associated with the high arm angular velocities and the eccentric forces generated by the external rotators to slow the arm after striking the ball. We used musculoskeletal modelling and simu...

Here we present a mathematical model that predicts the mechanical power of outdoor cycling measured in the crank arm. We derive this model from first principles to prescribe mechanical power as a function of speed and acceleration, which are described by a combination of cadence and gear ratio. In o...

Tendon is a multi-scale fibre composite material, in which highly aligned collagen units are interspersed with a more hydrated proteoglycan-rich matrix at multiple nano-to macro-length scales, leading to a tissue with excellent uniaxial tensile strength and stiffness. However, despite this well-acce...

Knee injury of China’s freestyle skiing athletes of aerial skills project accounts for up to 80% of the total injuries, and the most serious injury is cruciate ligaments injury. This study is to reveal the anterior cruciate ligament(ACL) and posterior cruciate ligament(PCL) injury mechanism and th...

There is little known about the mechanical effects of blood flow on finger flexor tendon (FDS) and subsynovial connective tissue (SSCT) motion. Ultrasonography recorded tissue motion during middle finger flexion-extension cycles with subdiastolic venous occlusion at two speeds. Occlusion altered FDS...

We introduce a simple experimental paradigm for estimating Achilles tendon stress and calibrating the wave speed squared-stress relationship for individual subjects. We observed strong linear relationships between wave speed squared and stress for 32 subjects, with some task- and subject-specific va...

Unilateral transtibial amputees lose the afferent pathways of the limb when amputation occurs. The addition of vibration has shown to increase sensation on the applied limb. This study looks into how the addition of subthreshold vibration affects amputee gait and posture. Vibration applied to the re...

In this paper, we give evidence to support the claim that there are two regions in balance control characterized by open-loop and closed-loop behavior. Subjects were equipped with a skin-stretch feedback device (SSD) at the fingertip to provide sensory augmentation [1]. It was found that skin-stretc...

Recently empirical mode decomposition (EMD) has been proposed to denoise the surface electromyography (EMG) signals. The EMD decomposes the signal in intrinsic mode functions (IMFs). The selection of IMFs that contain noise is usually selected based on noise thresholds. However, threshold amplitude ...

Nihon Kendo Kata, a form of practice where two individuals act out a predetermined protocol, is applied to assess skill level (dan grade) during the assessment for rank promotion in Kendo, a Japanese martial art. It is crucial to assess form for coaching using objective and quantitative methods. The...

Ligament rupture is among the most common musculoskeletal problems. Nevertheless, an ideal graft transplant helps to bring the patient back to normality. Nowadays, two types of graph transplants are used, however, they both present disadvantages: autograft, tends to lose their mechanical resistance ...

With the aim to obtain a better understanding of the potential contribution of the plantar-flexor muscle-tendon units to high-jump performance, muscle tendon properties as well as jump kinetics and kinematics in seven elite high jumpers. The results of this study clearly indicate that, different tak...
