The purpose of this study was to examine surface motor activation zones for wrist, fingers and thumb extension movements and their temporal change during 20 therapy sessions using advanced multi-pad functional electrical stimulation system. Results from four hemiplegic patients indicate that certain zones have higher probability of eliciting each of the target movements. However, mutual overlap and variations of the zones are present not just between the subjects, but also on the intrasubject level, reflected through these session to session transformations of the selected virtual electrodes. The obtained results could be used as a priori knowledge for semi-automated optimization algorithm and could shorten the time required for calibration of the multi-pad electrode.
本研究的目的是使用先进的多极板功能性电刺激系统，在20次治疗过程中检查手腕、手指和拇指伸展运动的表面运动激活区及其时间变化。四名偏瘫患者的结果表明，某些区域引发每种目标运动的可能性更高。然而，这些区域不仅在受试者之间存在相互重叠和变化，而且在个体内部层面也存在，这通过所选虚拟电极在各次治疗之间的转换得以体现。所获得的结果可作为半自动优化算法的先验知识，并可缩短多极板电极校准所需的时间。
