Preparing to Use a Prosthesis

by Erik Schaffer, CP

Before surgery, the surgeon, prosthetist, and physical therapist should discuss plans and goals with the patient. Also before surgery, patients should, if possible, discuss what happens after surgery with a peer counselor who has had an amputation.

Exercises to increase muscle strength and flexibility are taught by a physical therapist before and after amputation. The stronger and more flexible patients are, the more they can do with or without their prosthesis. Some exercises depend on the type of amputation. All patients need to do exercises to help reduce swelling in the stump and prevent contracture of tissues in the stump, which stiffens tissues, limits the joint’s range of motion, and thus makes using a prosthesis more difficult.

After surgery, the stump must heal before a prosthesis can be worn, and edema in the stump must be reduced before a prosthesis can be fitted for long-term use. To help reduce edema, patients are taught to apply an elastic sock (called a shrinker) or an elastic bandage over the stump. Wearing a shrinker or bandage also helps shape the stump and prevent irregularities that can make fitting the interface difficult. It increases circulation and makes phantom pain (pain in the amputated limb) less likely. For a while after surgery, a shrinker, bandage, or both are worn whenever the prosthesis is off. How long it is worn varies from patient to patient.

Until stump edema resolves, a temporary (preparatory) prosthesis may be used. Because this prosthesis is lightweight and easy-to-use, some experts think it helps patients learn to use a prosthesis more quickly. Later, this prosthesis is replaced with a permanent prosthesis, which has higher-quality components. However, with this approach, patients must learn how to use 2 different prostheses. An alternative approach is to use a prosthesis with permanent components (eg, knee, foot, hand) but with a temporary socket and frame. Because some parts remain the same, this approach may enable patients to adjust to the new parts more quickly. In either case, the first socket and frame almost always need to be replaced within 4 to 6 mo of amputation because the stump changes in shape and size.

When the prosthesis is delivered, patients are taught the basics of using it:

  • How to put the prosthesis on

  • How to take it off

  • How to walk with it

  • How to care for the skin of the stump and the prosthesis

Training is usually continued, preferably by a team of specialists. A physical therapist provides a program of gait training as well as exercises to improve strength, flexibility, and cardiovascular fitness. An occupational therapist teaches the skills needed to do daily activities. Patients with lower-limb amputations also learn advanced gait training skills (eg, using stairs, walking up and down hills, walking on uneven surfaces). Rehabilitation for upper-limb amputations is coordinated by an occupational or physical therapist with the prosthetist. Rehabilitation consists of specific exercises designed to strengthen muscles and maintain flexibility in the residual limb, as well as teaching patients how to use the prosthesis for daily activities.

Counseling or psychotherapy may help when patients have prolonged difficulty adjusting to the loss of their limb and to prosthetic use.
