Comparison Of Two Myoelectric Multi-Articulating Prosthetic Hands

Abstract

Myoelectric prosthetic hands with powered multi-articulating fingers offer users the promise of increased functional grasp options, previously unavailable in a myoelectric prosthetic hand. We take a comparison look at two multi-articulating myoelectric prosthetic hand systems, the bebionic v2 from RSLSteeper and the i-LIMB Pulse from Touch Bionics, Inc. These myoelectric prosthetic hands are categorically the same design, given that each hand has five multi-articulating powered fingers, including a thumb that can also be passively positioned in an opposed or non-opposed manner. By taking a closer look at each system, it is apparent that there are some unique features that differentiate these prosthetic hands. This comparison will focus on discussing the prosthetic hand features including available grip patterns, functional programming, graphic user interface, component compatibility, available load testing/grip force summary, battery options, glove options and sizing. In conclusion, the participant reader will have a better overall understanding of these systems and be better prepared to make a component decision regarding the desired clinical outcome for their clients.
