Trial Summary

What is the purpose of this trial?

Patients experience dramatic quadriceps strength loss after total knee replacement, which contributes to persistent weakness and reduced long-term function after surgery. Neuromuscular electrical stimulation (NMES) reduces quadriceps weakness and improves patient function after knee replacement, but it is drastically underused in rehabilitation practice. This randomized trial will examine the effectiveness and feasibility of a comprehensive strategy for implementing neuromuscular electrical stimulation after knee replacement in two large healthcare organizations.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the treatment NMES for total knee replacement?

Research shows that neuromuscular electrical stimulation (NMES) can help improve quadriceps muscle strength after total knee replacement, which is important for recovery and function. Studies have found that NMES can be an effective addition to traditional strengthening exercises, helping patients regain strength in their leg muscles.12345

Is neuromuscular electrical stimulation (NMES) safe for humans, especially after knee replacement surgery?

Research indicates that NMES is generally safe for humans, including those with metallic implants after knee replacement surgery. Patients in studies found NMES comfortable and acceptable, with no hypersensitivity reported at implant sites.12346

How is the treatment NMES different from other treatments for total knee replacement?

Neuromuscular Electrical Stimulation (NMES) is unique because it uses electrical impulses to strengthen the quadriceps muscle, which can help improve muscle strength and function before and after total knee replacement surgery. Unlike traditional physical therapy, NMES directly stimulates the muscles, potentially enhancing recovery and reducing muscle weakness more effectively.12345

Treatment Details

Interventions

  • NMES
Trial Overview The trial is testing Neuromuscular Electrical Stimulation (NMES) versus usual post-surgery care to see if NMES can better improve muscle strength and overall function after a knee replacement.
Participant Groups
2Treatment groups
Experimental Treatment
Active Control
Group I: NMESExperimental Treatment1 Intervention
Neuromuscular Electrical Stimulation (NMES) consists of usual care rehabilitation plus evidence-based implementation of NMES in the early postoperative period to improve physical function after TKA.
Group II: Usual CareActive Control1 Intervention
The Usual Care clinics will continue clinical practice as normal. Usual Care sites will not have overlap of personnel or training with NMES Sites.
