Ankle--Wounds and injuries; Leg--Muscles;


The purpose of this study was to determine the relationship of dynamic strength between the anterior and posterior compartments of the leg in ankle-injured athletes. Sixty-one highly skilled athletes were tested on the Cybex II isokinetic dynamometer to evaluate the muscle strength of the leg. Thirty of sixty-one athletes reported an injury to one or both ankles and were evaluated separately from the non-injured athletes. Muscular torque measurements from the Cybex pen recordings were recorded for each subject for plantarflexion and dorsiflexion. An independent group's t-test revealed no significant difference in muscular strength of the leg between the two groups at the .05 level. A trend-free measurement schedule was determined using analysis of variance procedures for both dorsiflexion and plantarflexion. Consequently, the average of trials three and four was utilized as the criterion score for subsequent analysis. A relationship of strength was determined between the anterior and posterior compartments of the leg by comparing the dorsiflexion score with the plantarflexion score. A 1:3 ratio was determined for subjects in both the injured group and non-injured. It was concluded that a 1:3 strength ratio between the anterior and posterior compartments of the lower leg might be used as a "benchmark" in the clinical assessment of the ankle.
