Background: Static and dynamic postures of lumbopelvic in low back pain (LBP) are considered as two importantaspects of clinical assessment and management of LBP. Thus, the focus of the current study was to compare theposture and compensatory strategy of hip and lumbar region during trunk flexion between LBP subgroupsand healthsubjects. LBP cases are subdivided into active extension pattern (AE...

Hip pain and dysfunction are increasingly recognised as important causes of morbidity in younger and older adults. Pathology compromising the passive stability of the hip joint, including acetabular labral injury, may lead to increased femoral head translation, greater joint contact pressures and ultimately degenerative hip disease. Activation of hip muscles may play an important role in augmen...

[Purpose] To measure electromyographic activity of the piriformis using fine-wire electrodes during 7 hip movements. [Subjects and Methods] Eleven healthy men, without severe low back pain or lower limb injury, participated in this study. Fine-wire electrodes were inserted into the piriformis and surface electrodes were attached to the muscles in the hip region and the trunk muscles on the domi...

Background Hip fracture is a worldwide public health problem that primarily affects osteoporotic individuals and the elderly. A second hip fracture can occur in elderly patients who have already suffered an initial hip fracture. The aim of this study was to investigate possible risk factors for second hip fractures in elderly patients with hip fractures. Methods Between 2010 and 2014, 230 pat...

The influence of an integrated hot isostatic pressing (HIP) treatment was investigated for two single-crystalline nickel-based superalloys under very high cycle fatigue at 1000 °C in fully reversed conditions (R? = ? 1). life is improved significantly by performing heat-treatments within the HIP unit. HIP-compacted pore morphology and its impact on crack initiation considered as well. HIPed spe...

Hip pain is a common and disabling condition that affects patients of all ages. The differential diagnosis of hip pain is broad, presenting a diagnostic challenge. Patients often express that their hip pain is localized to one of three anatomic regions: the anterior hip and groin, the posterior hip and buttock, or the lateral hip. Anterior hip and groin pain is commonly associated with intra-ar...

BACKGROUND High contact hip stress is believed to be one of the key biomechanical factors involved in the hip cartilage degeneration and osteoarthritis. Accordingly, with increasing age high contact hip stress is expected to cause elimination of subjects from the population of healthy hips, but its predictive value has not been evaluated so far. The objective of the paper is to investigate whet...

PURPOSE Slipped capital femoral epiphysis (SCFE) is one of the most common adolescent hip conditions. Unstable SCFE is characterized by sudden and severe hip pain with the inability to weight bear, even with crutches. Osteonecrosis of the femoral head is increased in patients with unstable SCFE. The aim of our study was to systematically review the literature that compares hip decompression to ...
