Objective To investigate the effects of different time periods of tail suspension and chronic low frequency stimulation ( CLFS ) on discharges of muscle spindle and muscle atrophy .

目的观察在吊 尾的不同时期（3、7、14d）及吊 尾加慢性低频电刺激（CLFS）14d后比目鱼肌肌 梭的传入放电有何改变。

Conclusion The results indicate that tail suspension produces muscle atrophy and decreases discharges of muscle spindle and both changes can be prevented by CLFS .

结论本研究结果提示 模拟失重可引起肌肉萎缩及肌 梭的传入放电减少，而慢性低频电刺激可以部分地对抗这些变化。
