Federal University of Health Science of Porto Alegre

Status: Completed

Conditions: Anterior Cruciate Ligament Injury

Treatments: Other: Isokinetic eccentric exercises; Other: Isotonic eccentric exercises

Study type: Interventional

Funder types: Other

Identifiers

NCT02961543

FUHSPortoAlegre_III

Details and patient eligibility

About

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.

Enrollment: 30 patients

Sex: Male

Ages: 18 to 40 years old

Volunteers: No Healthy Volunteers

Interventional model: Parallel Assignment

Masking: Double Blind

---

30 participants in 2 patient groups

Group 1.

Experimental group

Description:

The participants randomly allocated to this arm will undergo a muscular rehabilitation program based on the isokinetic eccentric exercise for the extensor muscles of the operated knee. The contralateral non-operated lower limb will be used as control, so it will not undergo any muscular rehabilitation program.

Treatment:

Other: Isokinetic eccentric exercises

Group 2.

Active Comparator group

Description:

The participants randomly allocated to this arm will undergo a muscular rehabilitation program based on the isotonic eccentric exercise for the extensor muscles of the operated knee. The contralateral non-operated lower limb will be used as control, so it will not undergo any muscular rehabilitation program.

Treatment:

Other: Isotonic eccentric exercises
