Detecting Change in Muscle Parameters, Pain, and Function With Neuromuscular Electrical Stimulation Treatment in Individuals Living With Transtibial Amputation
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.
• 18 years or older
• Have a unilateral transtibial amputation
• Have normal sound limb range of motion and function
• Have a minimum of 4 length limb from tibial tubercle to end of residuum to allow room for NMES pads
• Report current pain at a level 3 or higher on a Visual Analog Scale (VAS)
• Pass a monofilament test on the residual limb in 7 out of 10 areas to ensure adequate sensation for NMES stimulation
• Have a body mass index (BMI) of 35 kg/cm2 or less as NMES works more effectively on lower BMI
