Article

Sensory feedback systems have been of great interest in
upper-limb prosthetics. Despite tremendous research, there are no commercial
modality-matched feedback systems. This article aims to introduce the first
detachable and feedback add-on option that can be attached to in-use prostheses.
TECHNIQUE: A sensory feedback system was tested on a below-elbow myoelectric
prosthesis. The aim was to have the amputee grasp fragile objects without
crushing while other accidental feedback sources were blocked. DISCUSSION: A
total of 8 successful trials (out of 10) showed that sensory feedback system
decreased the amputee's visual dependency by improving awareness of his
prosthesis. Sensory feedback system can be used either as post-fabrication
(prosthetic add-on option) or para-fabrication (incorporated into prosthetic
design). The use of these direct feedback systems can be explored with a current
prosthesis before ordering new high-tech prosthesis. Clinical relevance This
technical note introduces the first attach/detach-able sensory feedback system
that can simply be added to in-use (myo)electric prosthesis, with no obligation
to change prosthesis design or components.
