Purpose
The anterior cruciate ligament (ACL) is frequently injured, and it is the structure of the athlete´s knee which has the highest prevalence of reconstruction. Given this postoperative ACL reconstruction scenario the investigator find in literature the effectiveness of neuromuscular electrical stimulation (NMES) as an adjuvant treatment for strengthening the quadriceps muscle. The intensity of NMES and the training duration are important factors for a successful treatment.
The purpose of this study is to compare two rehabilitation protocols in patients during the post operative of the ACL reconstruction over the strength of knee extension and control of edema.
It will be a randomized controlled study with the CONSORT bases with 40 participants that will be divided into two groups: Control group that will be submitted only to physical therapy exercises, and the Intervention group that will be submitted to physical therapy exercises plus electrical stimulation (low frequency device with a current of 47 Hz with symmetrical, biphasic and pyramidal waveforms, with pulse duration of 1.5 s and interval of 1.8 s). The procedure will last six weeks. It will be evaluated the pre intervention quadriceps muscle extension force by means of a manual dynamometer, and the joint swelling through the perimeter. This procedure will be repeated after six weeks of intervention. Results are expressed as hazard ratios (HR) with their respective confidence intervals at 95% and adopting α = 0.05. All analyzes will be performed by SPSS version 17.0
