Abstract

The use of strength measurements to predict strength gains is commonplace in the rehabilitation community. Athletic trainers, physical therapists and exercise scientists constantly use systems like the Biodex Dynamometer (Biodex Medical Systems, Shirley, N.Y.), to assess the progress of patients undergoing rehabilitation for injuries. Measurements taken on these devices often determine the status of patients permitting or barring them from full activity. Although use of these measurement devices to predict strength gains and functional ability is common, 2,3 some 3,4,5,7question the validity of the measurements. The value of isokinetic training methods has been questioned; 6 however, there has been no argument concerning the reliability of isokinetic testing when testing changes in strength.
