In some parts of the world poliomyelitis is still endemic and there are thousands of young people with joint contractures (Fig. 1). These most commonly occur at the knee, and the aim of treatment must be a straight knee with a useful range of painless flexion so that a hinged caliper can be worn. This paper reports experience in correcting flexion contractures of the knee following poliomyeliti...

[Purpose] The purpose of this study was to assess the effect of whole-body vibration exercise and plyometric exercise on female volleyball players. [Subjects and Methods] Subjects were randomly allocated to two exercise groups (whole-body vibration exercise group and plyometric exercise group). The exercise was conducted three times each week for 8 weeks. Isokinetic muscular strength, jumping p...

This study aimed to identify the effect of different stroke rates on various kinematic parameters during 1000 m outrigger canoeing. Sixteen, experienced female outrigger canoeists completed three 1000 m outrigger ergometer time trials, one trial each using a self-selected, a Hawaiian (≤ 55 strokes·min(-1)) and a Tahitian (≥ 65 strokes·min(-1)) stroke rate. Stroke rate, stroke length, stroke tim...

BACKGROUND Joint torques are generally of primary importance for clinicians to analyze the effect of a surgery and to obtain an indicator of functional capability to perform a motion. Given the current need to standardize the functional evaluation of the upper limb, the aim of this paper is to assess (1) the variability of the calculated maximal elbow joint torque during cyclic elbow flexion-ex...

It is of great interest to measure the properties of substructures in dark matter halos at galactic and cluster scales. Here we suggest a method to constrain substructure properties using the variance of weak gravitational flexion in a galaxy-galaxy lensing context. We show the effectiveness of flexion variance in measuring substructures in N-body simulations of dark matter halos, and present t...

A new posture measuring apparatus was developed for time and motion study in the field of industrial health. This apparatus records working postures by measuring angles of joints and trunk inclination. The angles of joints were measured by the newly developed goniometers which use the bending loss of rubber optical fibers. This paper presents results of studies made on the fixation, precision a...

BACKGROUND This study examined the clinical and radiologic mid-term results of patients treated by Oxford minimally invasive unicompartmental knee arthroplasty. METHODS One hundred and eighty-eight knees of unicompartmental knee arthroplasties with Oxford Uni® in 166 patients (16 males and 150 females), which were performed between 2002 and 2005, were reviewed. The mean age was 65.3 years (ra...

Background: Hamstring muscles contracture is a major problem in the management of the cerebral palsy CP patient causing the crouch gait which is one of the most resistant conditions to treat. Methods: Twenty patients (40 knees) with spastic cerebral palsy diaplegia, between 7 – 12 years of age, presented to The National Institute of Neuromotor System of Egypt, from January 2010 to January 2011....

BACKGROUND The purpose of this study was to compare the initial stability of anatomical and non-anatomical single bundle anterior cruciate ligament (ACL) reconstruction and to determine which would better restore intact knee kinematics. Our hypothesis was that the initial stability of anatomical single bundle ACL reconstruction would be superior to that of non-anatomical single bundle ACL recon...

Proximal interphalangeal (PIP) flexion contracture is a common complication following hand injuries and conditions. This study investigated the treatment outcome of 20 subjects with PIP flexion contracture who followed a dynamic splinting program using either a Capener or low-profile outrigger. The splint applied a 250-g force to the distal end of the middle phalanx. Each patient was instructed...
