Abstract
Purpose: The purpose of this study was to develope and determine the efficacy of a middle digit isokinetic eccentric strength dynamometer (MMD) in two groups of subjects. Methodes: The first group was composed of individuals without physician diagnosed lateral epicondylitis (13 males and 14 females), and the second group was composed of individuals who had physician diagnosed lateral epicondylitis (13 males and 14 females. A middle digital extension isokinetic dynamometer measured eccentric isokinetic torque, work, power, and angle at peak torque of the third finger. Results: Test-retest correlation values ranged from 0.83 to 0.45. ANOVA indicated a significant difference in work, power and angle at peak torque were indicated between the two subject groups. Conclusion: The middle digital extension isokinetic dynamometer appears to provide an acceptable means of evaluating effects of lateral epicondylitis therapy.
