Clinical research has shown EMS technology to be an effective treatment for quadriceps atrophy, which is associated with almost all knee injuries and that the use of KNEEHAB® can significantly reduce post-operative rehabilitation time.
- Trial 1The effectiveness of the Kneehab® in strengthening the quadriceps of patients in rehabilitation after anterior cruciate ligament reconstruction
- Trial 2Electrical stimulation versus voluntary exercise in strengthening thigh musculature after anterior cruciate ligament surgery
- Trial 3The effect of neuromuscular electrical stimulation on arthritis knee pain in older adults with osteoarthritis of the knee.

Electrical stimulation versus voluntary exercise in strengthening thigh musculature after anterior cruciate ligament surgery
Summary
Participants:20 patients who had undergone anterior cruciate ligament surgery.
Methods: Patients were assigned to an EMS group or a voluntary exercise group.
Results: Patients in the electrical stimulation regimen achieved higher individual thigh musculature strength gains than patients in a voluntary exercise regimen.

Objective: Twenty patients who had undergone anterior cruciate ligament reconstructive surgery were placed randomly and independently in an Electrical Stimulation Group (n = 10) or Voluntary Exercise Group (n = 10) to compare the effectiveness of these two muscle-strengthening protocols.
Study Design: Patients in both groups used simultaneous contraction of quadriceps femoris and hamstring muscles during a training regimen that consisted of either voluntary exercise or electrical stimulation trials five days a week for a three-week period within the first six postoperative weeks. After patients completed the training regimen, bilateral maximal isometric measurements of gravity-corrected knee extension and flexion torque were obtained for both groups and percentages were calculated.
Results: Results showed that patients in the Electrical Stimulation Group finished the three-week training regimen with higher percentages of both extension and flexion torque when compared with patients in the Voluntary Exercise Group (extension: t = 4.35, p less than .05; flexion; t = 6.64, p less than .05).
Conclusion: These results indicate that patients in an electrical stimulation regimen can achieve higher individual thigh musculature strength gains than patients in a voluntary exercise regimen when simultaneous contraction of thigh muscles is prescribed during an early phase of postoperative rehabilitation.
