Body-powered prosthetics — Ottobock USA

The history of medicine can be traced back as far as Neolithic man, but our understanding of medicine began with the Sumerians. Our knowledge of anatomy began with the Greeks, but truly took hold during the Middle Ages. Modern medicine can be traced back to discoveries made in the 17th century. That’s when William Harvey demonstrated the circulation of blood in the body, quinine was used to treat

Compared to a traditional body-powered prosthesis, a myoelectric-controlled arm provides greater comfort, more range of motion, a larger functional area, and a more natural appearance. It may, however, cost and weigh more.

Hybrid prostheses, which combine both myoelectric-controlled and body-powered components, is another option. A hybrid prosthesis may include a hand and wrist controlled that are myoelectrically along with an elbow that is controlled by a harness and cables worn on the torso and controlled by shoulder movements.

Conclusions: This study is a first step in the comparison of functional performances of body-powered prostheses.

Prosthetics for Upper Limb Amputation;

The purpose of this systematic review was to identify and evaluate the body of literature that compared BP and MYO prostheses and to synthesize the knowledge obtained into clinically useful evidence. In this 21 yr review period, 31 articles were available to support evidence statements regarding differences between MYO and BP prostheses. This is a crude publication rate of 1.5 articles per year, which does not seem considerably different from other areas of prosthetics and rehabilitation. Examples include a recent review of microprocessor knees that yielded 18 articles in a 14 yr review period (crude rate of 1.3 articles/year) [45] or spinal rehabilitation that yielded 11 randomized trials in a 13 yr review period (0.8 trials per year) [46]. The difference is that the reviews on microprocessor knees and spinal rehabilitation were reviewing only very specific studies (i.e., comparative effectiveness only), whereas this review included all study design types as well as editorials. The experiments included in this 14 yr review had a comparable publication rate of 0.2 articles/year, making the publication rate of upper-limb prostheses seem quite low.

Limb prostheses include both upper- and lower-extremity prostheses

Outside of surveys, there is little evidence addressing the functional capabilities of prostheses users and fewer studies making a direct comparison of prostheses in a controlled setting. A few standardized tests to directly evaluate prostheses function were found in multiple studies. Currently, evidence is insufficient to conclude that either the current generation of a MYO or a BP prosthesis provides a significant general advantage. Selection of a prosthesis should be made based on a patient's individual needs with regard to domains where differences have been identified. A patient's personal preferences, prosthetic experience, and functional needs are all important factors to consider. This work demonstrates that there is a lack of empirical evidence regarding functional differences in upper-limb prostheses.
