Detecting Change in Muscle Parameters, Pain, and Function With NMES for TTA

NCT06830876 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 20

Summary

The proposal aims to investigate a non-invasive, cost-effective method for rebuilding muscle mass in individuals with transtibial limb loss. Maintaining a healthy, pain-free residual limb is a primary concern for prosthesis users.

Amputees commonly experience muscle deficits leading to mobility issues, poor prosthetic fit, and chronic pain. Neuromuscular electrical stimulation (NMES) is a potential intervention that activates muscles with low-level electrical stimulation, improving strength, function, and reducing pain. The study seeks to understand NMES's effects on muscle parameters and pain to develop evidence-based interventions for amputees.

Twenty participants with transtibial amputations will undergo an 8-week NMES training program. Ultrasound imaging will assess muscle thickness, cross-sectional area, and composition changes. The study aims to enhance mobility, prosthetic fit, and overall well-being of amputees, addressing challenges and reducing healthcare burdens.

Interventions

DEVICE

Chattanooga Continuum Device

The Chattanooga Continuum (Enovis, Wilmington, DE) is an FDA-approved, multi-functional, dual-channel electrotherapy device that offers adjunctive rehabilitation therapies, including muscle re-education (NMES), pain control, and stimulation of local blood circulation. The device provides a treatment duration of up to 60 minutes, allowing for cycled or continuous therapy. It offers symmetrical and asymmetrical waveform types, adjustable pulse rates of up to 150 Hz, and pulse width durations of up to 400 μs. The device also features off times, channel ramp times, and on time settings. Additionally, the Continuum is equipped with a data and parameter logger, enabling the monitoring of patient usage. It incorporates an automatic lock function to prevent accidental changes in intensity by preventing unintended pressing of the control buttons. The device operates on two AA rechargeable NiMH batteries, and a battery charger and extra batteries are included with the device.
