N.Y. By comparing circumferential tape measurements of the amputated portion of the extremity with measurements of a corresponding region of the other arm, you can note the amount of edema and any changes. Hanlon also recommends measuring swelling with a volumeter, a technique where each hand is submerged in water that measures the amount of water that's displaced. A 10 to 15 milliliter difference between the two hands is considered normal, but anything greater than that's a sign of edema, she adds. For edema reduction, therapists train the patient in self-massage and positioning techniques, and might use modalities in acute cases. Hanlon recommends interferential current, since it reduces swelling and is effective reducing pain.
Many patients adopt unhealthy positioning techniques post-amputation.
Examine range of motion in the area immediately surrounding the amputation and in related musculature. For example, Hanlon says that while evaluating patients with amputations of the fingers, she checks range of motion in the same-side wrist, elbow and shoulders. For strength testing in the remaining portion of the hand, Hanlon recommends using a grip dynomometer and pinch meter two standard, well-known measures of grip strength. You should expect a loss of grip strength post-amputation, but these measures can help determine if there's any excessive weakness and provide a valuable baseline for rehab. Finally, evaluate the level of sensation in the remaining portion of the limb.
