The purpose of this study was to describe the firing pattern of 11 hip and knee muscles during running. Thirty recreational runners volunteered to run at 3 different paces with indwelling electromyographic electrodes while being filmed at 100 frames per second. Results demonstrated that medial and lateral vasti muscles acted together for knee extension during terminal swing and loading response...

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...

STUDY DESIGN Cross-sectional study. OBJECTIVE To compare functioning and disability in patients with hip osteoarthritis (OA) not candidates for surgery, to a matched control group, and thereby to examine the relationship between the functioning and disability components used in this study in patients with hip OA. BACKGROUND It is well known that patients with severe hip OA have deficits in ...

Larger hip flexion range of motion with knee extension (hip ROM) and passive stiffness the hamstring is associated greater production isometric concentric torque at longer muscle lengths. Nevertheless, associations among ROM, hamstring, eccentric a length remain unclear. Therefore, we aimed to investigate association angle-torque relationship. Seventeen healthy male college students participate...

OBJECTIVE To study the prevalence of ultrasonic hip joint effusion and its relation with clinical, radiological and laboratory (ESR) findings in adults with hip pain. METHODS Patients (n = 224) aged 50 years or older with hip pain, referred by the general practitioner for radiological investigation, underwent a standardised examination. The distance between the ventral capsule and the femoral...

The interaction between the semitendinosus muscle and both hip and knee joint angles was examined in the frog (Ranu pip&s) hindlimb. Sarcomere length was measured by laser diffraction in passive muscle during hip and knee rotation. A model was then developed to predict semitendinosus sarcomere length ;Ls a function of both hip and knee Rexion angle. Based on published frog muscle fiber length-t...

Comprehensive gait analysis of patients with Crowe type II and III developmental dysplasia of the hip (DDH) after successful total hip arthroplasty (THA) is lacking in the literature. This study evaluated gait function in joint kinematics after unilateral and bilateral THA in patients with DDH. In addition, the effect of high cup position on gait function was investigated. A total of 16 unilate...

This case report involves a 56-year-old female (Mrs X) with a traumatic intertrochanteric hip fracture with subtrochanteric extension below a previous Birmingham hip resurfacing. Periprosthetic fractures following hip resurfacing are usually subcapital and treated with a revision or conservative management. We present an unusual surgical problem with an interesting solution stabilising the frac...
