<p>Objectives: To compare the sensibility of the stump in adults with an acquired major upper extremity amputation with the sensibility of the unaffected side and with the corresponding body parts of healthy controls, as well as to relate the sensibility of the stump to daily functioning.</p><p>Design: A survey with matched controls.</p><p>Setting: A tertiary referral center.</p><p>Participants: A referred sample of patients (n=30) with an acquired upper extremity amputation, at least 1 year after amputation, and control subjects (n=30) matched for age, sex, and hand dominance were evaluated. Interventions: Not applicable.</p><p>Main Outcome Measures: Three different modalities of sensibility were measured: (1) touch-pressure sensibility, tested using Semmes-Weinstein monofilaments; (2) stereognosis, detected using the Shape and Texture Identification test; and (3) kinesthesia. Daily functioning was assessed using the Upper Extremity Functional Status Module of the Orthotics and Prosthetics Users' Survey.</p><p>Results: The mean time +/- SD since amputation was 20 +/- 17.8 years. Twenty patients used a prosthesis. The stump sensibility was similar to that of unaffected hands and tended to be less than that of unaffected arms (P=.08). The patients using a prosthesis had significantly poorer touch-pressure sensibility in the stump compared with the nonusers (P=.04). However, touch-pressure sensibility and stereognosis were worse in the patients than in controls (P</p><p>Conclusions: The touch-pressure sensibility in the stumps of patients using prostheses was poorer than the sensibility in nonusers, and' remarkably, the unaffected extremities of the amputees were less sensitive than the extremities of the controls.
