Neuromuscular Electrical Stimulation for Total Knee Replacement
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores a new rehabilitation method to improve recovery after total knee replacement. It focuses on neuromuscular electrical stimulation (NMES), which uses mild electrical pulses to strengthen thigh muscles. The goal is to determine if NMES can reduce muscle weakness and improve overall function after surgery. Ideal candidates for this trial are those who recently had a single knee replaced, began rehab within five days, and are receiving regular outpatient physical therapy. As an unphased trial, this study provides an opportunity to contribute to innovative rehabilitation research that could enhance recovery for future patients.
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 prior data suggests that neuromuscular electrical stimulation is safe for patients undergoing total knee replacement?
Research has shown that neuromuscular electrical stimulation (NMES) is generally safe for individuals recovering from total knee replacement. Studies suggest that NMES can strengthen the thigh muscles and improve their function post-surgery. Although there are no major safety concerns, some individuals might experience mild skin irritation at the electrode sites. Overall, this treatment is considered safe and can aid in muscle strength and recovery.12345
Why are researchers excited about this trial?
Researchers are excited about Neuromuscular Electrical Stimulation (NMES) for total knee replacement recovery because it offers a novel way to enhance physical function post-surgery. Unlike standard rehabilitation, which typically relies on physical therapy and exercises, NMES uses electrical impulses to stimulate muscles directly. This method can potentially accelerate recovery by improving muscle strength and function in the early postoperative period. By integrating NMES with usual care, there's a hope to significantly boost recovery outcomes and help patients regain mobility more quickly.
What evidence suggests that NMES is effective for improving quadriceps strength after knee replacement?
Research has shown that neuromuscular electrical stimulation (NMES), which participants in this trial may receive, can strengthen the quadriceps muscle after knee replacement surgery. A review of studies found that NMES not only increases muscle strength but also reduces pain and improves function post-surgery. Studies indicate that NMES can reduce the loss of quadriceps strength by 40% in the first month following surgery. Patients who used NMES experienced better mobility and quicker recovery, allowing them to stand up from a chair and walk a certain distance more easily. Significant improvements in physical function were noted at 6 and 12 weeks after surgery. These findings suggest that NMES is a promising method for improving recovery after knee replacement.14678

What Are the Treatments Tested in This Trial?
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.
How Is the Trial Designed?
2
Treatment groups
Experimental Treatment
Active Control
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.
The Usual Care clinics will continue clinical practice as normal. Usual Care sites will not have overlap of personnel or training with NMES Sites.
