The Efficacy and Safety of Electronic Stimulation in Patients Who Underwent Reconstruction of the Anterior Cruciate Ligament

Phase 1

Terminated

• Conditions: Knee Injuries

• Registration Number: NCT00312793
• Lead Sponsor: Hadassah Medical Organization

Brief Summary

This study is designed to evaluate the efficacy and safety of Myospare, a non-invasive device, which is connected to the body via electrodes placed in the injured leg. The electrodes which are placed in the middle or upper thigh will stimulate the quadriceps muscle.

Myospare will be installed 1 day after the anterior cruciate ligament (ACL) reconstruction surgery and will be removed after 6 weeks of treatment. The patients will be assigned to two groups:

1. Physiotherapy plus Myospare

2. Only physiotherapy

The hypothesis of the study is that electrical stimulation combined with voluntary exercise is more effective than voluntary exercise alone.
