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.
