PURPOSE To examine the long-term effects of hip arthrodesis in terms of gait adaptations. METHODS Motion analysis was performed on 9 patients who underwent unilateral hip arthrodesis between 1979 and 1991. A standard clinical gait analysis 3-dimensional model for the lower limb was used to calculate the effect of the fused hip on walking, compared with the contralateral normal hip. RESULTS ...

BACKGROUND Back extension (BE) is a strength exercise for training the dorsal trunk and hip muscles. To optimise training recommendations that avoid overloading and possible injury, the aim of this study was to determine the loading conditions and the influence of different execution forms of BE on spine, hip and knee ranges of motion (RoMs), joint moments and muscle activity. METHODS The kin...

hip dislocation occurs when the femur does not break and the force is transmitted towards the hip joint leading to a posterior dislocation of the femoral head with or without posterior acetabular fracture. we present the case of a 26 year old patient involved in motor vehicle accident. clinical and imaging (radiography, ct) examination revealed an intertrochanteric fracture associated with ipsi...

Aim of the Study: The aim of the study was to determine the relationship between the performance of six therapeutic exercises and muscle strength with standing ability in children with spastic diplegic cerebral palsy. Methodology: 50 subjects with spastic CP with ability to stand with one finger support or without support were randomly selected. The total standing duration without support or wi...

OBJECTIVE To investigate the influence of fatigue on phasic muscle-activation patterns during dynamic trunk extension exercise. DESIGN Fifteen healthy volunteers performed dynamic trunk-extension exercise through a 30-degree range-of-motion (ROM) exercise to task failure at an intensity of 50% of maximum. Electromyography (EMG) signals were recorded unilaterally from the lumbar extensor, glut...

Hip reduction in cerebral palsy patients with a soft tissue procedure was analysed during operative procedure. Eleven patients with unilateral dislocation of the hip and a quadriplegic form of cerebral palsy underwent soft tissue operation on the hips. Tenotomy of the adductor and flexor muscles of the hip was performed. The contralateral hip sustained only tenotomy of the adductor muscles. The...

We investigated the relationship between the pain experienced by 50 patients with osteoarthritis of the hip and the resting intra-articular pressure of the synovial fluid. We found a significant linear correlation between these factors, greater pain being experienced by patients with higher pressures. In 20 cases we showed that the pressure rises in extension and medial rotation and is least in...

Turtles with a complete transection of the spinal cord just posterior to the forelimb enlargement at the D2-D3 segmental border produced coordinated rhythmic hindlimb movements. Ipsilateral stimulation of cutaneous afferents in the midbody shell bridge evoked a rostral scratch. Electrical stimulation of the contralateral dorsolateral funiculus (DLF) at the anterior cut face of the D3 segment ac...
