Based on clinical observations, foot hyperpronation is very common. Excessive pronation (hyperpronation) can cause malalignment of the lower extremities. This most often leads to functional and structural deficits. The aim of this study was to assess the effect of foot hyperpronation on lumbar lordosis and thoracic kyphosis. Thirty five healthy subjects (age range, 18030 years) were asked to st...

OBJECTIVE to compare the biomechanics and performance while using a vertical computer mouse (VM) and a standard mouse (SM). METHODS muscle activation (electromyography), forearm movements (electrogoniometers), performance (Fitts' Law test) and satisfaction (questionnaire) of 16 subjects were evaluated. RESULTS there were significant differences between the VM and the SM, respectively, on mo...

BACKGROUND AND PURPOSE Musculoskeletal system deterioration among the aging is a major reason for loss of autonomy and directly affects the quality of life of the elderly. Articular evaluation is part of physiotherapeutic assessment and helps in establishing a precise diagnosis and deciding appropriate therapy. Reference instruments are valid but not easy to use for some joints. The main goal o...

Most studies on tilt based interaction can be classified as point-designs that demonstrate the utility of wrist-tilt as an input medium; tilt parameters are tailored to suit the specific interaction at hand. In this paper, we systematically analyze the design space of wrist-based interactions and focus on the level of control possible with the wrist. In a first study, we investigate the various...

Gulzar Saeed Ahmed1 ABSTRACT Objective: Function and appearance of the involved hand in patients with cerebral palsy can be improved by orthopedic surgery especially in spastic hamiplegia. Flexor carpi unlnaris transfer to extensor carpi radialis longus or bravis is a procedure commonly used for correction of flexion pronation deformity of hand in patients with cerebral palsy. Patients and Meth...

In patients with Brachial Plexus Birth Palsy (BPBP) both pronation and supination deformities can happen depending on the extent of injury, pattern of recovery and the resulting muscle imbalance. The main aim of the corrective surgery is to improve function but improving appearance of the limb is also an important consideration. Pronation posture is more important for bimanual and table top act...

This study compared golfers with and without the yips using joint movement and surface electromyographic detectors. Fifty golfers (25 with and 25 without complaints of the yips) were studied while putting. All putts were videotaped. Surface electromyography assessed arm cocontraction. A CyberGlove II (Immersion Technologies, Palo Alto, CA) assessed right-arm angular movements. Primary analysis ...

This study determined flexion and extension angles of resting fingers and wrist in terms of forearm posture (neutral, pronation and supination) and shoulder flexion (0°, 45°, 90° and 135°). The participants participated in 12 angle measurements for 16 finger joints and wrist. The finger joints flexed more in supination than in neutral posture and pronation and the thumb flexed more than the oth...
