Individuals with anterior cruciate ligament reconstruction (ACLR) exhibit asymmetry in a variety of tasks. The use of quadriceps strength symmetry as a rehabilitation guideline may not reflect biomechanical asymmetry in other tasks.

The IDEO brace improves function in limb salvage patients, yet the isolated power contribution by the brace has not been explored. Using two sets of tracking markers, it was found that the IDEO performed greater negative and positive work than the lower leg system. This is likely a result of the pro...

The study presents the preliminary result of a semi-qualitative analysis of lower limb joint angle coordination during gait in a lower limb amputee’s population. The aim of this study is to evaluate and compare the kinematic joint coordination between LLA and healthy individuals (and their possibl...

The impact of spasticity on walking is currently unclear. Assessments of spasticity require the assessor to move a limb as fast as possible, with potential discrepancies in testing velocity and range of motion between clinicians, as well as between what is observed during functional activities such ...

In the aerobics, bouncing is a basic and essential movement for superior competition performance. Aerobic gymnastics in competition are required bouncing and jumping under rhythm restriction in music. It is so important to clear how athletes operate their limbs smoothly and effectively under limited...

Reverse shoulder arthroplasty (RSA) usually leads to favourable clinical and functional results, yet some patients experience persisting limitations in shoulder range of motion (ROM). Shoulder abduction ROM is comprised of individual contributions of scapular rotation (between scapula and thorax) an...

It was recently reported that statistical parametric mapping (SPM) may be invalid for the analysis of nonuniformly smooth biomechanical data, like high frequency impact forces. The purpose of this study was to test that assertion. Using open-source software we simulated a variety of smooth Gaussian ...

Animals easily navigate complex terrain and can rapidly and safely reject unexpected perturbations. However, the underlying mechanism at the muscle-tendon level of this behaviour is unclear. To study this, we attached a real muscle-tendon unit to a novel bio-robotic interface that emulates interacti...

Articular cartilage (AC) is a fibre-reinforced connective tissue that covers the ends of articulating bones, providing joint lubrication, and thus allowing for smooth movement. Since AC is avascular, nutrients and proteins primarily transport via molecular diffusion. Thus, AC behavior has been exten...

For patients with knee osteoarthritis (KOA) downhill gait is often associated with pain. Therefore, the isometric muscle strength and gait biomechanics of 10 patients with moderate KOA was analysed during 4 different inclines and compared to a healthy control group (n=7). Patients with KOA showed si...

This study examined the viability of replacing traditional cross cutting techniques in a laboratory due to the difficulties of capturing high-intensity, “natural” cross cuts. Range of motion and peak moments about the knee were recorded for three tasks: traditional cross cutting, jump cutting, a...

Anterior Cruciate Ligament (ACL) tears often occur in landing situations due to unbalanced loading of the knee joint. In this study sagittal plane kinematics and kinetics of ACL reconstructed subjects were analysed during bilateral landing at six months after ACL reconstruction and compared to a mat...

In soccer and team handball, anterior cruciate ligament injuries often occur during abrupt changes of direction. The present study shows that the sidecutting manoeuvre is performed differently and results in different sagittal plane joint loadings, but no difference in frontal and transverse plane b...

Is black hole for real?

Different tests are used to assess postural control. This study evaluates dependence between Center of Mass (COM) movements (in four directions: forward, backward, left and right ) during voluntary postural sways and results of Limits of Stability (LOS). Healthy women over 50 years old, who exercise...

A number of recent studies have shown that the temporal structure of pacing signals greatly influences the gait dynamics observed when coordinating with those signals. Typically, those studies have focused on autocorrelation structure (ACF). The current study builds on that work by addressing how th...

The present study tested the hypothesis that increasing Achilles tendon stiffness by means of resistance exercise training will increase the effectiveness of calf stretching exercises for increasing gastrocnemius muscle fascicle length in children with CP. Measurements were taken in an intervention ...

After total joint replacement, patients aim to resume typical activities of daily living but also to perform sportive and athletic activities. However, there is only little knowledge about the in vivo joint loads acting during such activities. Furthermore the group of patients receiving an artificia...

The torso has always played an important role in baseball pitching. The movement of the upper limbs is greatly affected by the pelvis and trunk. Understanding the difference between the pelvis and the trunk will help coaches and players not only improve their pitching skills and also their pitching ...

Movement and muscle activity involving the lumbopelvic region differ between individuals who develop transient LBP during prolonged standing, compared to their pain-free peers. However, these findings involved low-demand tasks. Challenging task variations may elicit group differences previously unse...
