Prosthesis use in adult acquired major upper-limb amputees: patterns of wear,prosthetic skills and the actual use of prostheses in activities of daily life

Purpose: To describe patterns of prosthesis wear and perceived prosthetic usefulness in adult acquired upper-limb amputees (ULAs). To describe prosthetic skills in activities of daily life (ADL) and the actual use of prostheses in the performance of ADL tasks. To estimate the influence of prosthetic skills on actual prosthesis use and the influence of background factors on prosthetic skills and actual prosthesis use. Method: Cross-sectional study analysing population-based questionnaire data (n?=?224) and data from interviews and clinical testing in a referred/convenience sample of prosthesis-wearing ULAs (n?=?50). Effects were analysed using linear regression. Results: 80.8% wore prostheses. 90.3% reported their most worn prosthesis as useful. Prosthetic usefulness profiles varied with prosthetic type. Despite demonstrating good prosthetic skills, the amputees reported actual prosthesis use in only about half of the ADL tasks performed in everyday life. In unilateral amputees, increased actual use was associated with sufficient prosthetic training and with the use of myoelectric vs cosmetic prostheses, regardless of amputation level. Prosthetic skills did not affect actual prosthesis use. No background factors showed significant effect on prosthetic skills. Conclusions: Most major ULAs wear prostheses. Individualised prosthetic training and fitting of myoelectric rather than passive prostheses may increase actual prosthesis use in ADL.

Implications for Rehabilitation

• Arm prostheses are important functional aids for adult acquired major upper-limb amputees (ULAs).

• Despite being mainly satisfied with their prostheses, reporting their prostheses as useful and showing good prosthetic skills, prosthesis-wearing major ULAs do not use their prostheses for more than about half of the activities of daily life (ADL) tasks carried out in everyday life.

• In unilateral ULAs, individualised and targeted prosthetic training may increase optimal, active prosthesis use in ADL.

• Fitting the amputee with myoelectric rather than passive prostheses may increase prosthesis use in ADL, regardless of amputation level.
