Loss of one or both hands or loss of hand function requires an individual to make changes in his or her performance of activities of daily living. If a prosthesis or splint does not fulfill some personal requirement, it will not be worn. Personal requirements may be function-related, cosmetic or psychological in nature.
Early prosthetic fitting and training significantly influences the overall acceptance and functional use of an upper extremity prosthesis. Occupational therapists grade progress through assessment of tasks that can be completed, speed of task completion, and by assessing the manner in which the prosthesis is used for task completion.
