Background: Surgery that spares the intact portion of the ACL seems to be more favorable. This surgical technique has a positive effect on joint stability, joint position sense and functional scores in patients with partial ACL lesions. Aim: This study aimed to assess isokinetic muscle strength following surgical reconstruction of partial ACL lesions. Materials and Methods: The study included 1...

OBJECTIVES: To analyze the effects of motor learning on knee extension-flexion isokinetic performance in knee osteoarthritis patients. METHODS: One hundred and thirty-six middle-aged and older sedentary individuals (111 women, 64.3±9.9 years) with knee osteoarthritis (130 patients with bilateral) and who had never performed isokinetic testing underwent two bilateral knee extension-flexion (co...

BACKGROUND The relationship between muscle injury and strength disorders remains a matter of controversy. PURPOSE Professional soccer players performed a preseason isokinetic testing aimed at determining whether (1) strength variables could be predictors of subsequent hamstring strain and (2) normalization of strength imbalances could reduce the incidence of hamstring injury. STUDY DESIGN C...

[Purpose] To examine changes in the knee joint's isokinetic muscle functions following systematic and gradual rehabilitation exercises lasting for 12 weeks for male and female patients who underwent anterior cruciate ligament (ACL) reconstruction. Differences in muscle functions between the uninvolved side (US) and the involved side (IS) before surgery, differences in muscle functions between U...

BACKGROUND The purpose of this study was to evaluate the peak torque of the knee flexors (H) and the quadriceps muscle (Q) at 12 and 24 weeks after isolated anterior cruciate ligament reconstruction with semitendinosus and gracilis autografts. MATERIALS AND METHODS There were 20 patients (8 females, 12 males), with the mean age of 31.5 years. An isokinetic examination of the muscles was perfo...

BACKGROUND Many studies have compared different training methods for improving muscular performance, but more investigations need to be directed to the restoration of muscular imbalances. OBJECTIVE To determine the most effective training for altering strength ratios in the shoulder rotator cuff. METHODS Forty eight physical education students were randomly assigned to four groups (12 per g...

OBJECTIVE To determine the reliability of the Cybex 6000 isokinetic dynamometer in measuring the knee muscle performance concentrically and eccentrically. METHODS 18 male and 12 female subjects with no previous knee injuries, who had not previously undergone any isokinetic testing, were studied. The flexor and extensor muscles groups of both knees were tested at 60 degrees s-1 and 120 degrees...

OBJECTIVES To investigate the effects of isokinetic exercise on pain and functional test scores of recreational athletes with chondromalacia patellae (CMP) and to examine the correlation between isokinetic parameters and functional tests or pain score. METHODS The functional ability of 30 recreational athletes with unilateral CMP was evaluated using six different tests. Pain scores were asses...

OBJECTIVES To determine if the muscle force and electromyographic activity in the scapular rotators of overhead athletes with impingement symptoms showed differences between the injured and non-injured sides. METHODS Isokinetic peak force was evaluated during protraction and retraction of the shoulder girdle, with simultaneous recording of electromyographic activity of the three trapezius mus...

In this study a multiaxial isokinetic dynamometer was used to measure strength during various upper-body isokinetic exertions. Ten male participants performed 7 different upper-body isokinetic exertions. In addition, to evaluate the effect of speed on strength, each participant performed sitting pull exertions at the speed of 0.026, 0.130, and 0.260 m/s. Average isokinetic strength increased fr...
