    摘要:

    目的:目的:本研究通过观察变频振动训练对功能性踝关节不稳 (Functional Ankle Instability, FAI)患者下肢肌肉爆发力、平衡能力和踝关节周围肌肉功能的变化,为FAI患者的临床康复训练方法提供实证依据。方法:共招募26例FAI患者,并随机分为振动组(14人)和对照组(12人),振动组接受8周的康复训练及振动干预,对照组仅接受8周的康复训练。本研究在训练前、后测量和对比了受试者患肢单腿纵跳最大功率、平均功率、最大速度和平均速度,立定跳远距离,睁、闭眼单腿站立时间以及内侧腓肠肌(GM),外侧腓肠肌(GL)和胫骨前肌(TA)处的肌肉收缩时间(Tc),放松时间(Tr)和径向位移(Dm)。结果:实验组受试者的患肢单腿纵跳最大功率和最大速度、单腿立定跳远成绩和睁、闭眼单腿站立时间均显著提高,且其增幅都高于对照组;实验组中所有肌肉的Tc增幅均低于对照组,但Tr和Dm并没有呈现规律性。结论:变频振动训练能够有效地提高FAI患者下肢爆发力和平衡能力,促进GL、GM和TA的Tc缩短,但对降低肌张力和促进肌肉放松效果尚不明确。

    Abstract:

    Objective: In this study, the effect of vibration training on changes in explosive force of lower limbs, balance and muscle function around the ankle joint of FAI patients was observed while the vibration frequency was regularly adjusted, to provide an empirical basis for the clinical rehabilitation training methods of FAI patients. Methods: 26 eligible FAI patients were randomly divided into the vibration training group and the control group for 8 weeks of rehabilitation training. Changes in maximum power, average power, maximum speed and average speed of the vertical jump with single leg, changes in the long jump distance, changes in standing time of one-leg balance with eyes open and closed as well as changes in Tc, Tr and Dm of GL, GM and TA before and after training. Results: In the experimental group, the maximal power and maximum speed of the vertical jump with single leg, the long jump distance with single leg and the standing time of one-leg balance with open and closed eyes were significantly improved, moreover the increase was higher than that of the control group. The increase of Tc of all muscles in the experimental group was lower than that of the control group, but Tr and Dm did not show regularity. Conclusion: Vibration training with regularly frequency adjusted can effectively improve the explosive force and balance ability of lower limbs of FAI patients, and promote the shortening of Tc of GL, GM and TA, but it is not clear about reducing muscle tension and promoting muscle relaxation.
