BACKGROUND Injury of the acetabular labrum is a well recognized cause of hip pain in the young, active patient. The exact mechanism of these injuries remains a subject of speculation, although femoroacetabular impingement and twisting maneuvers have both been proposed as critical factors. We examined the hypothesis that torsional maneuvers of the morphologically normal hip joint generate mechan...

BACKGROUND Crouch gait is a major sagittal plane deviation in children diagnosed with cerebral palsy (CP). It is defined as a combination of excessive ankle dorsiflexion and knee and hip flexion throughout the stance phase. To the best of our knowledge, functional electrical stimulation (FES) has not been used to decrease the severity of crouch gait in CP subjects and assist in achieving lower ...

Many children with cerebral palsy walk with diminished knee extension during terminal swing, at speeds much slower than unimpaired children. Treatment of these gait abnormalities is challenging because the factors that extend the knee during normal walking, over a range of speeds, are not well understood. This study analyzed a series of three-dimensional, muscle-driven dynamic simulations to de...

Morton, SK, Whitehead, JR, Brinkert, RH, and Caine, DJ. Resistance training vs. static stretching: Effects on flexibility and strength. J Strength Cond Res 25(12): 3391-3398, 2011-The purpose of this study was to determine how full-range resistance training (RT) affected flexibility and strength compared to static stretching (SS) of the same muscle-joint complexes in untrained adults. Volunteer...

Purpose: Coronary angiography can cause post-procedural pain, and limited flexibility in the hips and knees may contribute to this discomfort. Patients with restricted hip and knee flexibility may experience increased stress. This study was designed to assess the flexibility of the hip and knee and its relationship with pain experienced after femoral angiography. Methods: This cross-sectional ...

Although there are not many reports in literature, iliopectineal bursitis presents clinically with signs and symptoms frequently found in outpatient services and practice. Its clinical presentation is anterior hip pain that worsens with the extension, abduction and internal rotation of the hip. The diagnosis is confirmed by ultrasound or magnetic nuclear resonance imaging of the hip. The iliope...

A girl of twenty had complained of pain in the right leg when walking, early fatigue and a limp, since breaking the right ankle three years before. She had not had any other accident or any illness. The knee could not be flexed without flexing the hip (Fig. 1). Conversely the hip could not be extended without extending the knee; indeed, extreme extension of the hipwas impossible even with the k...

BACKGROUND Obstetric fistula is essentially a result of pelvic injury caused by prolonged obstructed labour. Foot drop and walking difficulties in some of these women signify that the injury may extend beyond the loss of tissue that led to the fistula. However, these aspects of the pelvic injury are scarcely addressed in the literature. Here we specifically aimed at assessing musculoskeletal fu...

It is important to differentially diagnose thigh pain from lumbar spinal stenosis (particularly lumbar fourth nerve root radiculopathy) and osteoarthritis of the hip. In this study, using a treadmill and a motion analysis method, gait characteristics were compared between these conditions. Patients with lumbar fourth nerve root radiculopathy had increased physiological knee flexion immediately ...
