The choice of a myoelectric or body-powered upper-limb prosthesis can be
determined using factors including control, function, feedback, cosmesis, and
rejection. Although body-powered and myoelectric control strategies offer unique
functions, many prosthesis users must choose one.
A systematic review was
conducted to determine differences between myoelectric and body-powered
prostheses to inform evidence-based clinical practice regarding prescription of
these devices and training of users. A search of 9 databases identified 462
unique publications. Ultimately, 31 of them were included and 11 empirical
evidence statements were developed. Conflicting evidence has been found in terms
of the relative functional performance of body-powered and myoelectric
prostheses. Body-powered prostheses have been shown to have advantages in
durability, training time, frequency of adjustment, maintenance, and feedback;
however, they could still benefit from improvements of control. Myoelectric
prostheses have been shown to improve cosmesis and phantom-limb pain and are more
accepted for light=intensity work. Currently, evidence is insufficient to conclude that either system provides a significant general advantage. Prosthetic
selection should be based on a patient's individual needs and include personal
preferences, prosthetic experience, and functional needs. This work demonstrates
that there is a lack of empirical evidence regarding functional differences in
upper-limb prostheses.
