Strength, Pain and Function in Operation Iraqi Freedom/Operation Enduring Freedom Amputees: A Nurse-Managed Program

Summary

The purpose of this randomized control study is to determine if administering neuromuscular electrical stimulation (NMES) to the thigh muscles of a below the knee amputee is more effective than the current standard of care in preserving thigh muscle strength. In addition, this study will examine the NMES treatment effects on the participant's gait, quality of life, functional performance of standing, walking, and stair climbing, and symptoms associated with residual and phantom limb pain. The primary aim is to compare NMES plus standard rehabilitation (treatment group) to the standard rehabilitation (control group) by measuring lower extremity muscle strength. The secondary aims are to compare NMES treatment group to the control group by measuring Quality of Life (QOL) and the symptoms associated with residual \& phantom limb pain. In addition to the specific aims, this study will also examine the two groups for functional performance and gait patterns after prosthetic fitting.

Conditions

• Traumatic Amputation

Interventions

DEVICE

NMES (EMPI 300PV stimulator) plus standard of care

In addition to the standard rehabilitation, the NMES treatment group will receive neuromuscular electrical stimulation to the quadriceps muscle of the residual and intact limb. The name of the NMES device is EMPI 300PV. NMES training will consist of performing 15 to 20 minute stimulation sessions with a 5-minute patient treatment log, 5 times per week for 12 weeks. During each training session, 15 NMES contractions per leg will be completed. Each contraction will be elicited by an electrical impulse (300PV) generated by a battery-operated device. This will be performed at home.

BEHAVIORAL

TMARP standard of care

The usual care is 12 weeks of the Traditional Military Amputee Rehabilitation Program (TMARP). TMARP training starts 1week after surgical closure of the residual limb. Physical Therapy performs Pre-Prosthetic Training for about 6 weeks, preparing for the prosthetic. After pre-prosthetic training, patients are fitted with their prosthetic leg and began post-prosthetic training with PT. The training focus is lower limb prosthetic proficient in ambulation.
