Electrical Stimulation for Ruptured Achilles Tendon
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new rehabilitation method for individuals with a torn Achilles tendon using Neuromuscular Electrical Stimulation (NMES), which sends electrical pulses to muscles. The researchers aim to determine if NMES can reduce muscle loss and improve tendon healing compared to the usual recovery process. Participants will receive either standard therapy or standard therapy plus NMES, with the stimulation level gradually increasing over six weeks. This trial suits those who had surgery for an Achilles tendon rupture but excludes those whose tendon tear was treated without surgery, involved extra tissue during repair, or was linked to certain antibiotics. As an unphased trial, this study provides a unique opportunity to explore innovative rehabilitation techniques.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. However, if your tendon rupture is associated with the use of fluoroquinolones (a type of antibiotic), you would be excluded from participating.
What prior data suggests that this rehabilitation protocol using NMES is safe for Achilles tendon rupture?
Research has shown that Neuromuscular Electrical Stimulation (NMES) is generally well-tolerated. In past studies on NMES for various health issues, such as Achilles tendon problems, most participants did not experience serious side effects. The treatment sends small electrical pulses to muscles, aiding in contraction and strengthening.
Some participants have reported mild side effects, like skin irritation at electrode sites, but these are uncommon. Since NMES is already used for other health conditions, it appears to be quite safe. However, discussing potential risks with a healthcare provider before joining a trial is essential.12345Why are researchers excited about this trial?
Researchers are excited about using Neuromuscular Electrical Stimulation (NMES) for Achilles tendon repair because it offers a unique approach to rehabilitation. Unlike traditional treatments, which typically involve rest, physical therapy, and sometimes surgery, NMES directly stimulates the calf muscles with electrical impulses. This technique could enhance muscle strength and recovery speed by actively engaging the muscles during the healing process. By potentially accelerating recovery and improving muscle function, NMES represents a promising advancement in treating ruptured Achilles tendons.
What evidence suggests that this protocol is effective for Achilles tendon rupture?
Research has shown that Neuromuscular Electrical Stimulation (NMES), which participants in this trial may receive, can aid muscle recovery after an Achilles tendon rupture. NMES uses electrical signals to strengthen muscles, potentially preventing muscle wasting and improving tendon healing. One study found that NMES helped regain muscle strength more effectively than standard therapy alone. This is important because many patients struggle to fully recover strength after an Achilles injury. Early results suggest that NMES may support better long-term function in the injured leg.35678
Are You a Good Fit for This Trial?
This trial is for individuals who have experienced an Achilles tendon rupture and are undergoing recovery. It's not suitable for those who can't understand English, were treated non-operatively, had ruptures related to fluoroquinolone antibiotics use, or have conditions like diabetes or poor leg circulation that affect healing. People with augmented surgical repairs or allergies to ultrasound gel aren't eligible either.Inclusion Criteria

- NMES
Trial Overview
The study is testing a new rehab method using Neuromuscular Electrical Stimulation (NMES) on patients with Achilles tendon ruptures. The aim is to see if NMES helps reduce muscle loss and improve the quality of the repaired tendon compared to standard care.

Active Control
Patients will follow standard therapy for Achilles tendon repair.
Neuromuscular electrical stimulation will be applied to the calf muscles. The level of stimulation will be increased weekly from 10 to 30 mA during the first 6 weeks after surgery. In addition, patients will follow standard therapy for Achilles tendon repair.
NMES is already approved in United States, European Union for the following indications:
- Muscle wasting and weakness after subarachnoid hemorrhage (SAH)
- Rehabilitation post-SAH
- Muscle weakness and wasting in critically ill patients
- Rehabilitation post-SAH
