采用自制的电刺激器，微机加Ａ／Ｄ转换器构成波形发生器，对幅度感觉阈、脉宽感觉阈、脉宽分辨力、感觉适应性４项指标进行了测试。除适应性测试使用了２０个测试对象外，其它各项均有３０个测试对象。测试部位包括手指两侧、上臂、胸、背、腰、腹、耳垂。结果表明：（１）单向波幅度感觉阈高于双向波，（２）脉宽感觉动态范围８～１２ｄＢ，（３）脉宽可分辨级数为７～８，（４）触觉阈和痛阈随刺激时间的增加而增加，经过２０ｍｉｎ后，脉宽触觉阈值上升了约３．４５ｄＢ。
The self-made electrical stimulator and the computer plus A / D converter are used to form the waveform generator. The amplitude sensation threshold, the pulse width sensory threshold, the pulse width resolution and the sensory adaptability are tested. In addition to the 20 tests used in the fitness test, all 30 subjects tested. Test sites include the fingers on both sides, upper arm, chest, back, waist, abdomen, earlobe. The results show that: (1) the sensation threshold of unidirectional wave amplitude is higher than that of bidirectional wave; (2) the dynamic range of pulse width is 8 ~ 12dB; (3) the resolution of pulse width is 7 ~ 8; The threshold increased with the increase of stimulation time. After 20 minutes, the threshold of pulse width increased by about 3.45 dB.
