Once upon a time, in a land far, far away, lived a less than honorable ship captain who lost his hand during a sword fight with a young boy. The captain’s only option to replace his once very agile and useful hand was a simple iron hook. Although the story of Captain Hook and Peter Pan is not one based in fact, the existence of a hook-style prosthetic hand is no work of fiction. Thanks to the hard work and ingenuity of countless individuals spanning more than 2000 years, gone are the days where the well-known Captain Hook claw hand is the only hand prosthesis option.
Although select individuals continue to use a hand hook, there is a large variety in types, styles, and functions of hand prostheses commercially available on today’s market. Two of these hand prosthesis options include the i-limb Ultra and the Vanderbilt Multigrasp. One of the up-and-coming models of hand prostheses is the bebionic3 designed and produced by RSLSteeper. It is necessary to discuss information regarding the technology, biomechanical basis, functional abilities, suitable population, financial cost, metabolic cost, equipment specifications, and therapy’s role, to more fully understand this product.

bebionic3 Technology:
The bebionic3 is a type of myoelectric prosthesis. A myoelectric prosthesis is custom-made to fit and attach to the remaining limb of the user (either above the elbow or below) with maximum suspension using suction technology. Once attached, the prosthesis uses electronic sensors to detect muscle, nerve, and electromyography (EMG) activity. It then translates this m...
