Abstract

Sensory strength-duration curves were obtained using percutaneous true square-wave pulses ranging from 0.1 to 20.0 ms produced by an isolated constant current stimulator. In 119 healthy volunteers sensory thresholds were measured bilaterally by stimulating the distal phalange of the little finger. In order to examine the relationship of sensory threshold and handedness the latter was assessed by means of the Edinburgh Inventory. An asymmetry of sensory threshold was found for all the subjects and this was more pronounced with shorter stimuli. Of right-handers tested 73.5% had a lower threshold on the left side while 70.8% of left-handers had a lower threshold on the right side. Although threshold asymmetry is associated with handedness this is not necessarily due to cerebral lateralization.

摘要

使用由隔离恒流刺激器产生的范围为0.1至20.0毫秒的经皮真实方波脉冲获得感觉强度-持续时间曲线。在119名健康志愿者中,通过刺激小指的远端指骨双侧测量感觉阈值。为了研究感觉阈值与利手的关系,通过爱丁堡利手量表评估利手。发现所有受试者的感觉阈值均存在不对称性,并且在较短刺激时更为明显。在接受测试的右利手者中,73.5%的人左侧阈值较低,而在左利手者中,70.8%的人右侧阈值较低。虽然阈值不对称与利手有关,但这不一定是由于大脑的侧化。
