Numerous motion tests for diagnosing SIJ dysfunction have been described in the literature (van der Wurff et al 2000a & b). None is superior to another illustrating that physiotherapists should be suspicious with regard to the clinical relevance claimed by some authors. In general, motion tests of the SIJ can be reduced to 3 main directions: backward motion of the ilium (‘spine test’), forward ...

Knee joint forces are available by in vivo measurement using an instrumented knee prosthesis for small to moderate knee flexion but not for high flexion yet. We created a 2D mathematical model of the lower limb incorporating several new features such as a patello-femoral mechanism, a thigh-calf contact at high knee flexion and co-contracting muscles' force ratio, then used it to determine knee ...

[Purpose] This study compared the forward head angle and the lumbar flexion and rotation angles of computer workers using routine and fixed computer workstations. [Subjects] Ten male workers voluntarily consented to participate in the study. [Methods] A 3-D motion analysis system was used to measure the angles of the forward head and lumbar flexion. All subjects performed computer work for 30 m...

Safety standard requirements must be implemented for lumbar support robots, which are mainly used preventing low back pain (LBP) in caregivers. Usually, simulations to mimic actions that not allowed a real person. However, comprehensive validation of simulator dynamic conditions has been conducted. In this study, an ergonomic is validated through forward flexion invasive experiments. The corres...

BACKGROUND Neck and shoulder complaints can be a direct result of a neck dissection. METHODS Maximal active lateral flexion of the neck, forward flexion and abduction of the shoulder, and self-perceived function were determined in 145 patients treated for oral cancer. RESULTS No short-term influence of radiotherapy was found on measured range of motion and self-perceived neck and shoulder f...

The turtle generates a variety of coordinated hindlimb movements, including different forms of locomotion and scratching. The intact turtle produces forward step, forward swim, and backpaddle. Following spinal cord transection, rostral, pocket, and caudal scratches can be evoked by mechanical stimulation of the shell. Comparisons of the kinematics and motor patterns of these six behaviors provi...

The aim of this study was to investigate how balance ability according to angle of the knee joint changes in young female adults wearing a knee orthosis. [Methods] This study was conducted with 11 healthy female adults. The subjects used a knee brace that could be set to angles of 0°, 15°, and 30° of knee flexion. The ability to balance was evaluated by balance assessment. A total of four postu...

OBJECTIVES The Constant-Murley score (CS) has been used for more than 25 years to assess shoulder function. Strength by itself accounts for 25% of the total score. The measurement at 90° abduction seems to be sometimes limited by pain, particularly with tendinopathy or subacromial impingement. We compared the assessment of isometric strength in anterior forward flexion and abduction and its eff...

BACKGROUND Understanding glenohumeral motion in normal and pathologic states requires the precise measurement of shoulder kinematics. The effect of the plane of arm elevation on glenohumeral translations and rotations remains largely unknown. The purpose of this study was to measure the three-dimensional glenohumeral translations and rotations during arm elevation in healthy subjects. METHODS...
