Strategy of exercise prescription using an unloading technique for functional rehabilitation of an athlete with an inversion ankle sprain.
METHODS
Case study.


OBJECTIVE
To demonstrate how an exercise program can be designed with specific sets, repetitions, and rest periods, and to enhance the healing process in early stages of rehabilitation when injured tissues cannot tolerate full body weight. Our goal was to enhance ankle tissue healing by reducing gravitational force through a prescriptive exercise and unloading program.


BACKGROUND
This report describes a treatment method that we used to rehabilitate a collegiate soccer player with a Grade II inversion ankle sprain. This athlete sprained his ankle 6 weeks before the start of rehabilitation and was unable to participate in soccer due to persistent pain and impaired function.


METHODS
A 2-week functional training program was implemented, consisting of exercises chosen for specific task simulation related to soccer. Gravitational force was mechanically altered by suspending the subject or by supporting the subject on a variable incline plane. Weight-bearing was controlled so that the subject could perform exercises without pain. The outcome measures were ankle range of motion (ROM), maximum pain-free isometric strength, vertical force during unilateral squats, and unilateral hop time and distance.


RESULTS
Pain-free weight-bearing capacity increased over the 2-week course of rehabilitation and the subject was able to return to playing soccer without pain. The ratios (involved to uninvolved extremity) at time of discharge from physical therapy were 87% to 103% for ankle ROM, 75% to 93% for isometric ankle strength, 91% for unilateral squats, 88% for unilateral hop time, and 86% for unilateral hop distance.


CONCLUSIONS
Return to function can be achieved in a short period by exercise that is performed with a gradual increase in pain-free weight-bearing capacity.
