| 摘 要： | 目的：通过新型的肌肉无创诊断技术--肌肉功能状态分析仪（TMG），分析振动训练后下肢肌肉的机械收缩状态，评估振动训练的效果和慢性踝关节不稳（CAI）患者恢复过程中下肢肌肉功能状态的变化。方法：招募并筛选出慢性踝关节不稳患者13例，随机分为实验组（振动训练组，7人）和对照组（非振动训练组，6人）。振动训练组下肢功能训练在Power Plate振动台上进行，而对照组的训练在非振动台上进行。训练负荷及时间：持续时间30 min，刺激频率为45 Hz，一周两次，共8周。两组受试者者在病情、症状、体征、纳入标准上均无差异。测试指标：采用肌肉状态分析仪（TMG）测试肌肉的机械收缩指标，主要指标有肌肉收缩时间（Tc）、放松时间（Tr）、径向位移（Dm）。测试肌肉包括腓肠肌内、外侧（GM、GL）和胫骨前肌（TA）。结果：8周的训练后与实验前相比，振动训练组和对照组较实验前Tc都有所增加，但对照组增加的更多，两组较实验前都没有显著性差异。振动训练组GM的Tr时间缩短了12.3%，对照组增加了45.7%，较实验前有显著性差异，P＜0.05。对照组变化的比率较振动训练组也有显著性差异，P＜0.05, 而TA和GL虽有变化，但无显著差异。振动训练组TA的Dm增长13.52%，对照组却缩短了0.25%，但都没有显著性差异。振动训练组GL、GM的Dm分别增长了42.7%、38.4%，较对照组有显著性差异。实验组受试者睁眼单腿站立时间较实验前提高61.2%，差异显著，P＜0.05。对照组睁眼单腿站立时间较实验前提高44.9%，无显著性差异。结论：CAI患者在康复训练过程中，TA、GM和GL的收缩时间和径向位移均增加，而放松时间没有明显的一致性变化，这提示振动训练可以提高CAI患者的肌肉收缩能力。振动训练和常规训练均可以提高CAI患者的平衡能力，但振动训练的效果更显著。TMG可以作为CAI患者康复过程中肌肉功能状态的评估手段。

| Abstract: | Using a new type of muscle noninvasive diagnostic technique-muscle functional state analyzer (TMG) to analyze the mechanical contraction of the lower limb muscles after the vibration training to evaluate the effect of the vibration training and the changes of the functional state of the lower limbs during the recovery of the chronic ankle instability (CAI). Methods: 13 patients'' who are Zhengzhou university students with knee injury were recruited as participants. The participants were divided randomly into experimental group which included 7students, and the control group including six people. Muscles contraction indexes of the lower limb muscles function measured by TMG were: Contraction Time(Tc), Relaxation Time(Tr), and Maximum Radial Displacement (Dm). The standing time with or without eyes open were also tested. Results: after 8 weeks of training, compared with pre-experiment, the Tc time of experimental group and control group increased, and the control group increased much more. But there was no significant difference compared with pre-experiment. The Tr time of GM in the experimental group was shortened by 12.3%, but increased by 45.7% in the control group, which was significantly different from pre-experiment, P<0.05. The rate of change in the control group was also significantly different from that in the experimental group, P<0.05. Although the time of Tr of TA and GL all have changed, there is no significant difference. The Dm of TA in experimental group increased by 13.52%, while that in control group was shortened by 0.25%, and there was no significant difference. The Dm of GL and GM in the experimental group increased by 42.7% and 38.4% respectively, which was significantly different from the control group. The time of standing on one leg in the experimental group increased by 61.2% compared with pre-experiment, and the difference was significant, P<0.05. The standing time of the control group increased by 44.9% compared with pre-experiment, but there was no significant difference. Conclusion: During the rehabilitation training of CAI patients, the contraction time and radial displacement of TA, GM and GL all increased, while the relaxation time did not show a significant consistent change. This suggests that vibration training can improve muscle contraction in CAI patients. Both vibration training and routine training can improve the balance ability of CAI patients, but the effect of vibration training is more significant. The results of this study indicate that TMG can be used as a means to evaluate the muscle function state during the rehabilitation of CAI patients. |
