STUDY DESIGN Controlled laboratory study, repeated-measures design. OBJECTIVES To compare hip abductor muscle activity during selected exercises using fine-wire electromyography, and to determine which exercises are best for activating the gluteus medius and the superior portion of the gluteus maximus, while minimizing activity of the tensor fascia lata (TFL). BACKGROUND Abnormal hip kinema...

PURPOSE OF THE STUDY Gluteal muscle contracture (GMC) is a chronic fibrotic disease of gluteal muscles which is characterized by excessive deposition of collagen in the extracellular matrix. Transforming growth factor (TGF)-βs have been shown to play an important role in the progression of GMC. However, the underlying mechanisms are not entirely clear. We sought to explore the expression of TGF...

Acute gluteal artery syndrome secondary to superior gluteal artery injury following pelvic fracture is a rare entity with potential for significant morbidity and mortality. In this report we present such a case resulting with a favorable outcome with prompt diagnosis and appropriate treatment.

Umbilical artery catheters are an essential aid in the treatment of newborn infants who have cardiopulmonary disease. However, it is well-known that umbilical artery catheterization is associated with complications. The most frequent visible problem in an umbilical line is blanching or cyanosis of part or all of a distal extremity or the buttock area resulting from either vasospasm or a thrombo...

OBJECTIVE To compare the regional differences in subcutaneous adipose tissue hormone/cytokine production in abdominally obese women during weight loss. METHODS Forty-two abdominally obese, older women underwent a 20-week weight loss intervention composed of hypocaloric diet with or without aerobic exercise (total energy expenditure: ∼2800 kcal/week). Subcutaneous (gluteal and abdominal) adipo...

Pioneering epidemiological work has established strong association of sedentary lifestyle and obesity with the risk of colorectal cancer, while the detailed underlying mechanism remains unknown. Here we show that Hotair (HOX transcript antisense RNA) is a pro-adipogenic long non-coding RNA highly expressed in gluteal-femoral fat over other fat depots. Hotair knockout in adipose tissue results i...

OBJECTIVES This study investigated changes in craniocervical and trunk flexion angles and gluteal pressure on both sides during visual display terminal (VDT) work with continuous cross-legged sitting. METHODS The gluteal pressures of ten VDT workers, who were recruited from laboratories, were measured using a Teckscan system and videotaped using a single video camera to capture the craniocerv...

Pressure ulcers classified as Stage IV (according to National Pressure Ulcer Advisory Panel staging guidelines) [1] take a long time to heal, and may cause serious infections, such as osteomyelitis and sepsis [2-5]. Thus, they usually require surgical repair using a muscle or fasciocutaneous flap (according to International Guidelines). Treatment of Pressure Ulcers: Quick Reference Guide) Glute...

Deep gluteal syndrome describes the presence of pain in the buttock caused from non-discogenic and extrapelvic entrapment of the sciatic nerve. Several structures can be involved in sciatic nerve entrapment within the gluteal space. A comprehensive history and physical examination can orientate the specific site where the sciatic nerve is entrapped, as well as several radiological signs that su...
