This is especially critical given the high cost associated with the acquisition and implementation of MCTs and the need to make an(More)
Foot-pounds of torque of the knee flexors and knee extensors of eight rehabilitated patients who had had meniscectomies were obtained isometrically and at 60 and 210 degrees per second by use of an isokinetic apparatus. Our purpose was to test the null hypothesis that no significant difference in torque would be manifested between the rehabilitated(More)
This study describes anorexia nervosa (AN) patients who use excessive exercise for weight management and how this behaviour relates to the classical Diagnostic and Statistical Manual of Mental Disorders - Fourth Edition (DSM-IV) sub-grouping of AN. The study compared 428 clinical AN patients with 119 age and gender-matched controls. The AN cases were(More)
The purpose of this investigation was to determine the relationship of torque developed by knee extensor muscles to torque developed by knee flexor muscles as a result of rehabilitation programs for patients with chondromalacia, ligamentous repairs, and meniscectomies. Peak torque of knee extensor and flexor muscles was measured at slow dynamic and rapid(More)
