Clinical Trial Summary

A randomized clinical trial involving 30 individuals submitted to ACL reconstruction will be conducted.

Participants will be randomized into: Group I, submitted to a muscular rehabilitation program based on eccentric isokinetic exercise; and Group II, submitted to a muscular rehabilitation program based on eccentric isotonic exercise. Concomitantly with the muscular rehabilitation protocols, individuals will undergo the same physiotherapeutic protocol with analgesia, edema reduction, range of motion, proprioception and functionality goals. Muscle rehabilitation programs based on eccentric isotonic and isokinetic exercise will begin 45 days after ACL reconstruction. The programs will last six weeks, with training frequency of two sessions per week, separated by a minimum interval of 72 hours.

Intervention

Other:
• Isokinetic eccentric exercises
The individuals of both groups will be submitted to the same physiotherapeutic protocol with objectives of analgesia, reduction of edema, recovery of range of motion, proprioception and functionality. 45 days after ACL reconstruction, subjects randomly allocated to this arm will be submitted to a muscle rehabilitation program based on isokinetic eccentric exercise lasting six weeks, with training frequency of two sessions per week, separated by a minimum interval of 72 hours.
• Isotonic eccentric exercises
The individuals of both groups will be submitted to the same physiotherapeutic protocol with objectives of analgesia, reduction of edema, recovery of range of motion, proprioception and functionality. 45 days after ACL reconstruction, subjects randomly allocated to this arm will be submitted to a muscle rehabilitation program based on isotonic eccentric exercise lasting six weeks, with training frequency of two sessions per week, separated by a minimum interval of 72 hours.
