Background: Hamstring tendons are secondary hip extensors. Their harvest for graft in anterior cruciate ligament(ACL) reconstruction may create deleterious effect on hip extension strength. This is of particular importance in sportsthat need powerful hip extension force like climbing and sprinting. Due to scarcity of a comprehensive study in thisarea, we designed this prospect...

Introduction. Osteoarthritis (OA) of the hip is one of the major causes of pain and disability in the older population. Although exercise is an effective treatment for knee OA, there is lack of evidence regarding hip OA. The aim of this trial was to test the safety and feasibility of a specifically designed exercise program in relieving hip pain and improving function in hip OA participants and...

Measurements of human strength can be important during analyses of physical activities. Such measurements have often taken the form of the maximum voluntary torque at a single joint angle and angular velocity. However, the available strength varies substantially with joint position and velocity. When examining dynamic activities, strength measurements should account for these variations. A mode...

OBJECTIVE To determine the preoperative strength of the muscle group of the lower extremity that is most important in predicting functional recovery after primary unilateral total hip replacement (THR). DESIGN Prospective observational study with inception cohort. SETTINGS Joint care program (hospital care/clinical division of a nursing home/outpatient physical therapy). PARTICIPANTS Pati...

We compared two methods of reconstruction of the abductor mechanism in 15 patients after prosthetic replacement of the upper femur, to assess abductor strength and function. Six patients in group I had direct fixation of the gluteus medius tendon and a segment of the original bone to the prosthesis. Nine patients in group 2 had the abductor tendon fixed to the iliotibial band. We assessed clini...

The injury rate in football is high, and effective injury prevention methods are needed. An exercise program, the "11," has been designed to prevent the most common injury types in football. However, the effect of such a program on performance is not known. The aim of this randomized-controlled trial was to investigate the effect of the "11" on performance after a 10-week training period. Thirt...

OBJECTIVE To evaluate the test-retest reliability of isometric and isokinetic muscle strength measurements in the upper extremity after stroke. DESIGN A test-retest design. SUBJECTS Forty-five persons with mild to moderate paresis in the upper extremity > 6 months post-stroke. METHODS Isometric arm strength (shoulder abduction, elbow flexion), isokinetic arm strength (elbow extension/flex...

Hand grip strength is frequently used as a measurement of muscle strength, especially among older adults. Muscle only one the many components in postural control and it currently unclear to what extent hand associated with control. The aim was analyze association between lower limb Forty-five community-dwelling individuals over 70 years age provided isometric (including hip extension abduction,...

STUDY DESIGN Cross sectional study. PURPOSE To evaluate characteristics of back muscle strength in patients scheduled for lumbar fusion surgery. OVERVIEW OF LITERATURE Little is known regarding muscle strength in patients with symptomatic lumbar degenerative diseases who require fusion surgery. METHODS Consecutive 354 patients scheduled for posterior lumbar interbody fusion due to symptom...
