BACKGROUND AND PURPOSE Active stretching is purported to stretch the shortened muscle and simultaneously strengthen the antagonist muscle. The purpose of this study was to determine whether active and passive stretching results in a difference between groups at improving hip extension range of motion in patients with hip flexor muscle tightness. SUBJECTS AND METHODS Thirty-three patients with...

Objective: To investigate changes in muscle strength in the lower extremity after ACL reconstruction. Design: Prospective case series. Dependent Variables: Isokinetic muscle strength measured in 6 movements (hip extension/flexion, hip adduction/abduction, knee extension/flexion) and circumference of the thigh/calf. Setting: Clinic and home. Patients: 44 (24 men, 20 women) between the ages of 16...

OBJECTIVE To establish the relationships between the range of joint motion (ROM) and disability in patients with osteoarthritis (OA) of the knee or hip. Two related issues were addressed: (1) the inter-relationships between ROMs of joint actions, and (2) the relationship between ROM and disability. METHODS Data on 198 patients with OA of the knee or hip were used. The ROM was assessed bilater...

AIM The purpose was to describe posture, ability to change position, and association between posture and contractures, hip dislocation, scoliosis, and pain in young adults with cerebral palsy (CP). METHODS Cross-sectional data of 102 people (63 males, 39 females; age range 19-23 y, median 21 y) out of a total population with CP was analysed in relation to Gross Motor Function Classification S...

CONTEXT Lower extremity (LE) weakness might be associated with altered mechanics during weight bearing in subjects with patellofemoral pain syndrome (PFPS). OBJECTIVE To analyze LE strength, mechanics, and the association between these variables among women with and without PFPS during a simulated athletic task. DESIGN Case control. SETTING Motion-analysis laboratory. SUBJECTS 20 women ...

OBJECTIVES FRAX incorporates rheumatoid arthritis (RA) as a dichotomous predictor for predicting the 10-year risk of hip and major osteoporotic fracture (MOF). However, fracture risk may deviate with disease severity, duration or treatment. Aims were to validate, and if needed to update, UK FRAX for patients with RA and to compare predictive performance with the general population (GP). METHO...

Introduction In normal individuals, hip flexion involves combined motion of the femur with respect to the pelvis and flexion of the lumbar spine. Conflicting reports site insufficient head to neck diameter ratio and fear of instability as limiting factors of post-hip resurfacing (SRA) and total hip replacement (THR), respectively. Restoring anatomical range of motion is important for THR and SR...
