Article Synopsis
  • This study explores the impact of limb positions and electrode shifts on the effectiveness of pattern recognition (PR) systems used for controlling upper limb prostheses, highlighting potential issues with classification accuracy.
  • Researchers found that both factors lead to a decrease in classification performance by 14-21%, and they achieved high accuracy rates of 96.13% for single motions but only 65.40% when all motions were considered.
  • The findings suggest that limb positions and electrode shifts create new, statistically distinct classes within the data, emphasizing the need for further research with more amputee data to improve the robustness of myoelectric control systems.

Significant advances in bionic prosthetics have occurred in the past two decades. The field's rapid expansion has yielded many exciting technologies that can enhance the physical, functional, and cognitive integration of a prosthetic limb with a human. We review advances in the engineering of prosthetic devices and their interfaces with the human nervous system, as well as various surgical techniques for altering human neuromusculoskeletal systems for seamless human-prosthesis integration.

Introduction: Myoelectric pattern recognition systems have shown promising control of upper limb powered prostheses and are now commercially available. These pattern recognition systems typically record from up to 8 muscle sites, whereas other control systems use two-site control. While previous offline studies have shown 8 or fewer sites to be optimal, real-time control was not evaluated.

Article Synopsis
  • Researchers explored the effectiveness of biomimetic (natural movement) vs. arbitrary (unrelated movement) control strategies in training users to operate a bionic hand.
  • Both training methods improved bionic limb control and increased users' sense of embodiment, but biomimetic users had quicker success initially.
  • Findings suggest that an ideal training approach may blend aspects of both strategies, tailored to individual needs and training conditions for better overall control.
