The purpose of the present study was to determine the extent to which lower extremity muscular strength is an independent predictor of proximal femur BMD in healthy older adults. It was hypothesized that the BMD of the proximal femur in older adults would not be related to the maximum voluntary isometric strength of the hip, knee, and ankle muscles after adjusting for the influence of body weig...

Objectives The aim of this work is to show that the pelvis represents the focal point of the postural system, or rather, the link between muscular and skeletal systems. The pelvis is the seat of insertion of lower extremity and trunk musculature, and these muscles are controlled by the postural system. The afferent postural information relayed by this musculature conditions the spatial order of...

[Purpose] This study investigated the effects of the bridging plus exercise with heel lift on lower extremity muscles. [Subjects and Methods] Nine healthy males participated. The subjects performed bridging exercises under two conditions. Surface electromyography was used to measure the electrical activities of the medial hamstring (MH) and the gluteus maximus (GM) muscles. [Results] Activation...

The purpose of this study was to determine modulation of pre- activity related to different types and heights of deep jump. Sixteen male soccer players without experience in deep jumps training (the national competition; 15.0 ± 0.5yrs; weight 61.9 ± 6.1kg; height 1.77 ± 0.07m), who participated in the study, performed three types of deep jump (bounce landing, counter landing, and bounce drop ju...

[Purpose] The purpose of this study was to investigate the effects of a pelvic belt on the activities of trunk and lower extremity muscles in normal adults. [Subjects and Methods] The subjects were 20 normal individuals without a history of orthopedic problems. The pelvic compression belt (The Com-Pressor, OPTP, Minneapolis, MN, USA) was an adjustable body belt with four elastic compression ban...

We report a case of fibrodysplasia ossificans progressive in a 34-year-old male who presented with bilateral lower-extremity numbness. This rare disease results in abnormal ossification of various muscles, tendons, and ligaments. In this case, there was ossification of the posterior longitudinal ligament and resultant thoracic spinal-cord compression. Recognizing the MR features of this disease...

A 29-year-old woman with relapsed T-cell acute lymphoblastic leukemia presented 4 months of progressive ataxia, weakness, and bowel/bladder incontinence. Symptoms started after completing 2 cycles nelarabine. Examination revealed paraplegia complete sensory loss from mid-chest down, vibration joint position in upper limbs, areflexia, bilateral Babinski signs. EMG showed fibrillation potentials ...

The extremities of the human body contain several bi-articular muscles. The actions produced by muscles at the joints they cross are greatly influenced by joint moment arms and muscle length. These factors are dynamic and subject to change as joint angles are altered. Therefore, to more completely understand the actions of such muscles, the angles of both joints must be manipulated. This report...

Case report. A 51-year-old Hispanic woman with a history of Churg-Strauss syndrome (in remission for 20 years)–associated mesangial glomerulonephritis and end-stage renal disease with a recent renal transplant and previously cured cytomegalovirus (CMV) infection who was on a tapering dose of tacrolimus presented with sudden onset of lower extremity numbness. Symptoms progressed to complete para...
