The bottleneck in upper limb prosthetic design is the myoelectric control algorithm. Here we studied the clinical readiness of the myoelectric postural control algorithm in a laboratory setting with two trans-radial amputees using a commercially available prosthetic limb system.
The postural control algorithm was integrated into prosthetic limb systems using standard of care components. A comparison between a commercial state of the art system (the i-limb revolution state-based myoelectric controller) and the postural controller was performed with two people with trans-radial amputation using a self-contained prosthesis system.
The performance using the i-limb revolution state-based controller versus the postural controller was mixed based on the Southampton Hand Assessment Procedure. The SHAP scores indicate that the postural controller with i-limb revolution provided an average of 66% of hand function compared to an intact limb. Future work will study the advantages of the postural control algorithm in everyday use.
上肢假肢设计的瓶颈在于肌电控制算法。在此，我们在实验室环境中，使用市售假肢系统，对两名经桡骨截肢者研究了肌电姿势控制算法的临床适用性。
姿势控制算法通过护理标准组件集成到假肢系统中。使用独立假肢系统，对两名经桡骨截肢者进行了商业先进系统（i-limb revolution基于状态的肌电控制器）与姿势控制器之间的比较。
根据南安普顿手功能评估程序，使用i-limb revolution基于状态的控制器与姿势控制器的性能有好有坏。南安普顿手功能评估程序（SHAP）评分表明，与健全肢体相比，配备i-limb revolution的姿势控制器平均提供了66%的手部功能。未来的工作将研究姿势控制算法在日常使用中的优势。
