Crossbred steers (n = 30) were used to explore and compare tenderness improvements in beef round and sirloin muscles resulting from various methods of prerigor skeletal separations. Animals were slaughtered according to industry procedures, and at 60 min postmortem one of six treatments was applied to each side: A) control, B) saw pelvis at the sirloin-round junction, C) separate the pelvic-fem...

PURPOSE For patients who have anterior hip pain evaluated by Patrick's test and tenderness at Scarpa's triangle, we perform periarticular debridement based on the hypothesis that extra-articular pathologies are responsible for the hip pain. The purpose of this study was to categorize the endoscopic extra-articular findings and to evaluate the clinical significance of periarticular pathologies i...

Little information exists about the intensity of contraction required from knee and hip musculature during common therapeutic exercises used for patient populations. This study, therefore, was designed to compare electromyographic data obtained from the vastus medialis, rectus femoris, gluteus medius, and biceps femoris muscles during maximally resisted straight-leg-raising (SLR) exercises with...

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...

We report six caucasian patients who had acute pain in the hip and marked limitation of all movement of the joint. Plain radiographs and CT of the pelvis showed calcification within the reflected head of rectus femoris. All six responded to accurate CT-controlled injections of corticosteroid and local anaesthetic with dramatic and prolonged pain relief, although one required a second injection ...

The purpose of this study is to investigate the effect of sit to stand movement on the muscle activity of lower extremities muscles by the different type of chair and posture. Total 52 healthy adult between 19 and 26 were selected as subject for the study. The muscle activities of vastus lateralis, rectus femoris, vastus medialis, tibialis anterior and gastrocnemius by the different types of ch...

In this study, the fiber type specificity of dihydropyridine receptors (DHPRs) and ryanodine receptors (RyRs) in different rat limb muscles was investigated. Western blot and histochemical analyses provided for the first time evidence that the expression of both receptors correlates to a specific myosin heavy chain (MHC) composition. We observed a significant (p=0.01) correlation between DHP as...
