Ask upper-limb prosthetics providers about the strengths and weaknesses of myoelectric and body-powered prostheses and the reasons for preferring one or adopting both, and you’ll get a collection of responses as varied as the patients they serve.
Among the factors one must consider when creating a second device or terminal attachment for a patient with an upper-limb amputation is how they will integrate it into their daily life, says Shane Grubbs, CPO/L, FAAOP, director, ProCare Ottobock.care, Georgia. “Some like wearing the myoelectric prosthesis with a bionic hand when they leave home, because they can adapt their grip for function and look more natural. If they use a body-powered prosthesis with a hook, there can be a somewhat cultural negative connotation to its appearance which undermines its utility.”
