Upper extremity (including fingers, partial hand, wrist disarticulation, below-elbow, elbow disarticulation, above-elbow, shoulder and forequarter arm) amputations range from vascular to trauma, young to old, sports enthusiasts to basic ambulation. Every patient has his or her own ideas of success, so each patient is assessed by their clinician to create a customized rehabilitation program that is consistent with their individual goals.
The advancements in technology with upper extremity prosthetic components have been amazing with the development of microprocessor-controlled hands and elbows. These advancements enhance the functional capabilities of the upper extremity patient. This enhancement is only possible with a properly fitted socket. Carolina Orthotics and Prosthetics upper extremity specialists will conduct a thorough evaluation of the residual limb, listen to the patient’s goals and objectives, and together they will determine what system best fits his/her needs.eds.
Conventional/Body Powered Prosthesis
A conventional or body powered prosthesis controls the elbow and terminal device through a harness and cabling system.
Electrically Powered Prosthesis
The myoelectric prosthesis functions through electrodes, which operate a motor to create movement by opening and closing the hand, rotating the wrist or flexing and extending the elbow. These actions occur by contracting muscles in the residual limb, which then initiates the process to create function.Advancements have made it where fingers with some myoelectric hands no longer work as a unit but may move individually.
The hybrid upper extremity prosthesis will incorporate both conventional, as well as electrically powered control functions for the same prosthesis.
