A patient with a permanent prosthesis reports the prosthesis feels too heavy two weeks after final approval. The patient will benefit MOST from:

• A. An evaluation of socket fit by the prosthetist
• B. Reevaluation of hip strength by the therapist
• C. A prescription from the physician for lighter weight prosthesis
• D. Fork strap attachment to the prosthesis

Answer: (B)

Prosthesis heaviness is most often due to insufficient proximal (hip and core) strength, which makes controlling and propelling the prosthesis require more effort. When hip extensors, abductors, and trunk stabilizers are weak, the patient cannot efficiently stabilize the pelvis and control the prosthetic limb during stance and swing, leading to greater energy expenditure and the sensation that the device is heavy. A therapist’s evaluation of hip strength helps identify specific deficits and guides targeted strengthening and motor-control training to improve gait efficiency and reduce fatigue. Addressing socket fit with the prosthetist is important if there are fit or comfort issues, but heaviness from weakness is best addressed through strengthening and gait rehabilitation. A lighter-weight prosthesis or strap modifications don’t directly correct the underlying control and endurance problems that your hip strength assessment would reveal.
