Changes in sensory and motor functions of the hand in type II diabetes (T2D) patients have been reported; there is speculation that these changes are driven by tactile dysfunction. The purpose of this study was to evaluate the effects of tactile feedback on manual function in T2D patients.
T2D patients and healthy controls underwent median nerve blocks at the wrist and elbow. All participants underwent traditional timed motor evaluations, force dynamometry, laboratory-based kinetic evaluations, and sensory evaluation.
Tactile sensation in the T2D group at baseline was found to be equivalent to tactile function of the control group after median nerve block. Traditional timed evaluation results were negatively impacted by anesthesia, but more sensitive kinetic measures were not impacted.
These data suggest that mechanisms outside of tactile dysfunction play a significant role in motor dysfunction in T2D. Muscle Nerve 54: 895-902, 2016.
已有报道称II型糖尿病（T2D）患者手部的感觉和运动功能发生了变化；有人推测这些变化是由触觉功能障碍引起的。本研究的目的是评估触觉反馈对T2D患者手部功能的影响。
T2D患者和健康对照者在手腕和肘部接受正中神经阻滞。所有参与者都接受了传统的定时运动评估、握力测量、基于实验室的动力学评估和感觉评估。
发现T2D组在基线时的触觉感觉与正中神经阻滞后对照组的触觉功能相当。传统的定时评估结果受到麻醉的负面影响，但更敏感的动力学测量指标未受影响。
这些数据表明，触觉功能障碍以外的机制在T2D的运动功能障碍中起重要作用。《肌肉与神经》54: 895 - 902, 2016年。
