摘要:
 【摘要】目的：确定坐骨神经损伤后大鼠臀大肌、小腿三头肌固有频率，并观察不同状态下其固有频率是否一致，为康复治疗频率的选择提供实验依据。方法：将24只SD大鼠随机分为空白组、模型组、麻醉组。模型组行坐骨神经钳夹伤术；麻醉组处以水合氯醛麻醉；空白组不做任何干预。造模后第7天通过振动仪器为大鼠臀大肌、小腿三头肌施加冲击振动激励，在振动响应检测模块测得的数据基础上，根据实时频谱观察、时频分析方法，确定大鼠臀大肌、小腿三头肌固有频率。结果：每个受试部位有两个规律性明显的峰值：（1）空白组、模型组、麻醉组大鼠臀大肌、小腿三头肌第一峰值频率无显著性差异（P>0.05），臀大肌、小腿三头肌在同一组别（相同状态）中其固有频率无明显差异（P>0.05）；（2）空白组、模型组、麻醉组大鼠臀大肌、小腿三头肌第二峰值频率无显著性差异（P>0.05），臀大肌、小腿三头肌在同一组别（相同状态）中其固有频率无统计学差异（P>0.05）。结论：臀大肌、小腿三头肌的第一峰值为其固有频率（8.25、8.12 Hz）；肌肉组织的固有频率是稳定的，同一肌肉组织的固有频率不会因其所处状态不同而发生较大差异。
Abstract:
 Abstract: Objective To determine the natural frequencies of gluteus maximus and triceps muscles of the calf in rats after sciatic nerve injury, and to observe whether their natural frequencies are consistent under different states, so as to provide experimental evidence for the selection of rehabilitation frequency. Methods A total of 24 SD rats were randomly divided into 3 groups, namely blank group, model group and anesthesia group. The rats in model group suffered from sciatic nerve injury; those in anesthesia group were anesthetized with chloral hydrate; and those in blank group didn’t receive any intervention. On the 7th day after modeling, shock vibration excitation was applied to gluteus maximus and triceps muscle of the calf by vibration instrument. Based on the data measured by the vibration response detection module, the natural frequencies of gluteus maximus and triceps muscle of the calf were determined by real-time spectrum observation and time-frequency analysis method. Results There were two regular peaks at each test site. (1) No significant difference was found in the first peak frequencies of gluteus maximus and triceps muscle of the calf among 3 groups (P>0.05), and the natural frequencies between gluteus maximus and triceps muscle of the calf in the same group (the same state) (P>0.05). (2) There was no significant difference in the second peak frequencies of gluteus maximus and triceps muscle of the calf among 3 groups (P>0.05), and the natural frequencies between gluteus maximus and triceps muscle of the calf in the same group (same state) (P>0.05). Conclusion The first peaks of gluteus maximus and triceps muscle of the calf are their natural frequencies (8.25 and 8.12 Hz, respectively). The natural frequency of muscle tissue remains stable, and the state has trivial effects on the natural frequency of the same muscle tissue.
