title: Reliability of isokinetic muscle testing at the ankle.
abstract: The purpose of this study was to determine the intrarater and interrater reliability of mean peak torque values for the reciprocal motions of plantarflexion/dorsiflexion (PF/DF) and inversion/eversion (INV/EVER), generated isokinetically at 60 and 120 degrees /sec. Forty-one healthy subjects, ranging in age from 20-75, were tested on three different occasions. The three test sessions were performed at the same time of day and separated by at least 24 hours. Pearson product-moment correlations were used to determine reliability for all ankle motions tested. Intrarater reliability of peak torque values for PF/DF and INV/EVER at both speeds ranged from 0.78-0.94, while the range of interrater coefficients was from 0.82-0.94. The results of this study suggest that when using a well defined clinical protocol, acceptable reliability for both test-retest and interrater situations can be obtained for isokinetic peak torque values of the ankle musculature at low and relatively high test speeds.
