INTRODUCTION Snapping hip, or coxa saltans, is defined as a clinical condition where a usually painful, audible snap occurs during hip flexion and extension. Its causes can be divided into external, internal or intra-articular origin. Accurate diagnosis is a prerequisite to successful treatment. We report a rare cause of snapping hip which is different from any previously reported cases. CASE...

QUESTION Is acute in-hospital physiotherapy with additional progressive knee-extension strength training (ST) of the fractured limb more effective in reducing knee-extension strength deficit at follow-up compared to physiotherapy without strength training in patients with a hip fracture? DESIGN Assessor blinded, randomised controlled trial with intention-to-treat analysis. PARTICIPANTS 90 p...

Background: Proximal hamstring repair for complete ruptures has become a common treatment. There is no consensus in the literature about postoperative rehabilitation protocols following proximal hamstring repair. Some protocols describe bracing to prevent hip flexion or knee extension while others describe no immobilization. There are currently no biomechanical studies evaluating proximal hamst...

Laboratory data indicate the hip capsular ligaments prevent excessive range of motion, may protect the joint against adverse edge loading and contribute to synovial fluid replenishment at the cartilage surfaces of the joint. However, their repair after joint preserving or arthroplasty surgery is not routine. In order to restore their biomechanical function after hip surgery, the positions of th...

Host identity protocol (HIP) has security support to enable secured mobility and multihoming, both of which are essential for future Internet applications. Compared to end host mobility and multihoming with HIP, existing HIPbased micro-mobility solutions have optimized handover performance by reducing location update delay. However, all these mobility solutions are client-based mobility solutio...

BACKGROUND Recent studies have questioned the efficacy of releasing hip flexion contractures and the resulting ankle position after tendoachilles lengthening in ambulating children with cerebral palsy (CP). METHODS Twenty-three ambulatory children with CP underwent 96 soft tissue-lengthening procedures without bony surgery. Preoperative and postoperative clinical and computerized gait data we...

STUDY DESIGN Cross-sectional case-control design. BACKGROUND Although the etiology of patellofemoral pain syndrome (PFPS) is not completely understood, there is some evidence to suggest that hip position during weight-bearing activities contributes to the disorder. OBJECTIVE To compare the knee and hip motions (and their coordination) during stair stepping in female athletes with and withou...

Avascular necrosis of femoral head (ANFH) is a common complication affecting about 25% of the patients treated with corticosteroids after kidney transplantation. Patient complains of severe pain, limitation of hip range of motion especially abduction and external rotation, also affect the gait and activity of daily living. The current study was conducted to detect the effect of faradic stimulat...

In human spinal cord injury (SCI), imposed unilateral hip movements trigger multijoint, coordinated reflexes that might incorporate interneuronal circuitry involved in normal motor control, such as neural pathways associated with the reflex control of locomotion. To further investigate the complexity of these hip-triggered reflexes, we measured the effects of kinematics of the contralateral hip...

OBJECTIVE To establish the relation between handball playing, passive hip range of motion (ROM), and the development of radiological hip osteoarthritis (OA) in former elite handball players. Two related issues are addressed: (a) the relation between long term elite handball playing and the incidence of hip OA; (b) the relations between hip ROM, OA, and pain. METHODS Data on 20 former elite ha...
