Upper Extremity Myoelectric Prosthetics

Differences in myoelectric and body-powered upper-limb prostheses: Systematic literature review

“…BP prostheses, further, are noted to be easier to clean and maintain functionality with less adverse effect to function in the presence of loss of fit. Confidence in this statement is low because it is supported by multiple expert opinion articles [9,[43][44]; however, implications for this statement are considerable. BP hooks are also declared to be simple, robust, and well-suited for manual labor [43].…”

“…Confidence in this statement is low because it is supported by multiple expert opinion articles [9,[43][44]; however, implications for this statement are considerable. BP hooks are also declared to be simple, robust, and well-suited for manual labor [43]. When healthcare costs are a factor, the facts that BP systems require less training and that they are more durable than alternatives also have appeal and can assure enhanced functionality with potentially less healthcare financial resources.…”

“…For instance, users indicate BP prostheses are better suited for working conditions that include light sitting work or combined sitting/standing work but could also include exceedingly heavy work [9,43]. In contrast, MYO prostheses tend to be used for only light work [9,33].…”

“…Ten studies of varying quality and design (Table 4) suggest that, depending on functional needs, control scheme familiarity, and user preference, either BP with a conventional hook or MYO prostheses are advantageous compared with each other or other alternatives [9][10]17,21,24,29,[38][39][43][44]. The range of study designs supporting this statement includes expert opinion, observational, and experimental designs.…”

“…This is in contrast to externally powered systems whereby control is via myosignaling, which offers no feedback comparable to BP actuation, which tells the user how much a split hook is presently open. Proprioceptive feedback is another reported benefit of cableactuated devices whereby kinetic and kinematic data are exchanged between prosthesis and residual limb during manipulation [9,43]. An additional means of feedback associated with BP system use is visual information [9].…”
