Abstract
Electrical stimulation was applied daily for 20 minutes to denervated rabbit extensor digitorum longus muscle. One group was stimulated with short tetani, another with 1-Hz frequency, using isometric contractions for both. Tetanic stimulation induced severe fibrosis and is harmful to denervated muscle. One Hertz stimulation retarded denervation-induced fatigue and atrophy, as well as slowing of contraction time.
摘要
每天对去神经支配的兔趾长伸肌施加20分钟的电刺激。一组采用短强直刺激，另一组采用1赫兹频率刺激，两组均采用等长收缩。强直刺激会导致严重纤维化，对去神经支配的肌肉有害。1赫兹刺激可延缓去神经支配引起的疲劳和萎缩，以及收缩时间的减慢。
