Recent advances in human-machine interface technology have enabled the development of multifunctional, primarily orthopedic myoelectric prostheses. We developed a noninvasive blinking periorbital prosthesis that can synchronize with blinking of the intact eyelid by using surface electromyographic signals of the orbicularis oculi muscle.
Myoelectric potentials of the orbicularis oculi muscle while blinking were measured with surface electrodes on the eyelid in four healthy adults. Possible cross talk introduced via the electrodes was also measured and assessed to determine whether cross talk would affect surface electromyographic measurements while blinking.
The amplitude of the surface myoelectric potential of the orbicularis oculi muscle was sufficiently high for the practical use of blinking prostheses. Our blinking model was successfully synchronized with blinks of the subjects' eyelids under experimental conditions without cross talk between the orbicularis oculi muscle and other muscles.
Although our study revealed several problems, the use of surface electromyographic signals could be a promising and useful technique for synchronizing blinking of the prosthetic eyelid with blinking of the intact eyelid. Level of Evidence: Level V, therapeutic study.
人机接口技术的最新进展推动了多功能、主要用于矫形的肌电假肢的发展。我们开发了一种无创眨眼眶周假肢，它可以通过使用眼轮匝肌的表面肌电信号与完整眼睑的眨眼同步。
在四名健康成年人的眼睑上使用表面电极测量眨眼时眼轮匝肌的肌电电位。还测量并评估了通过电极引入的可能串扰，以确定串扰是否会影响眨眼时的表面肌电测量。
眼轮匝肌表面肌电电位的幅度足够高，可实际用于眨眼假肢。在没有眼轮匝肌与其他肌肉之间串扰的实验条件下，我们的眨眼模型成功地与受试者眼睑的眨眼同步。
尽管我们的研究揭示了几个问题，但使用表面肌电信号可能是一种有前景且有用的技术，可使假眼睑的眨眼与完整眼睑的眨眼同步。证据级别：V级，治疗性研究。
