优化人工舌位触觉生物反馈用于改善人类踝关节位置感
Optimizing the Use of an Artificial Tongue-Placed Tactile Biofeedback for Improving Ankle Joint Position Sense in Humans
摘要：
在12名年轻健康成人中使用主动匹配任务评估人工舌放置触觉生物反馈装置用于改善踝关节位置感的性能。该系统的基本原理包括通过舌头放置的触觉输出设备向个体提供关于匹配踝关节相对于参考踝关节位置的位置的补充信息，该触觉输出设备在保持抵靠舌背表面的36点（6 X 6）矩阵上产生电触觉刺激。准确地说，（1）当两个踝关节在预定的“角度死区”（ADZ）内处于相似的角度位置时，没有电极被激活;（2）激活基质前、后区各12个电极（2 × 6）（对应于舌头的前部和后部的刺激）当匹配踝关节相对于参考踝关节分别处于过度跖屈和背屈位置时。评估了0.5度和1.5度的两个ADZ值。结果表明：（1）有生物反馈的匹配性能比无生物反馈的匹配性能更准确和更一致;（2）使用ADZ值较小的生物反馈装置时，踝关节匹配性能更准确和更一致
英文摘要：
The performance of an artificial tongue-placed tactile biofeedback device for improving ankle joint position sense was assessed in 12 young healthy adults using an active matching task. The underlying principle of this system consists of supplying individuals with supplementary information about the position of the matching ankle relative to the reference ankle position through a tongue-placed tactile output device generating electrotactile stimulation on a 36-point (6 X 6) matrix held against the surface of the tongue dorsum. Precisely, (1) no electrodes were activated when both ankles were in a similar angular position within a predetermined "angular dead zone" (ADZ); (2) 12 electrodes (2 X 6) of the anterior and posterior zones of the matrix were activated (corresponding to the stimulation of the front and rear portion of the tongue) when the matching ankle was in a too plantarflexed and dorsiflexed position relative to the reference ankle, respectively. Two ADZ values of 0.5 degrees and 1.5 degrees were evaluated. Results showed (1) more accurate and more consistent matching performances with than without biofeedback and (2) more accurate and more consistent ankle joint matching performances when using the biofeedback device with the smaller ADZ value
