摘要:

文题释义:
交互抑制:是当支配一肌肉的运动神经元受到传入冲动的兴奋,而支配其拮抗肌的神经元则受到这种冲动的抑制,此种生理活动现象称为交互抑制。
闭锁延长:“闭锁延长”与“闭锁缩短”这一组词语是对主动肌与拮抗肌状态的一种修饰,《解剖列车》P124中提到闭锁延长状态的肌肉通常是“哭闹”那块,有痛感或活性触发点,解决根源却在闭锁缩短的肌群;肌筋膜以张拉整体结构为载体,主动肌与拮抗肌之间存在筋膜间的力学联系,其产生机制较多但生理角度并不能全面对此名词进行解释。同时作者认为闭锁延长并不单纯等同于生理学中的肌紧张,为防止起止点过度延长而产生持续的收缩,体现在“交互抑制”效应当中发现其有放电现象而定义为增加了关节的稳定性;其状态以肌丝滑行理论进行分析更为直观。
背景:足外翻激活练习是足踝康复领域重要的干预途径,在康复实践中广泛应用,但其对拮抗肌产生的交互抑制效应尚不明确。
目的:探究足外翻肌群激活练习后对拮抗肌产生的交互抑制效应。
方法:选择大学生自愿受试者18名。使用弹力带进行足外翻等长收缩练习,干预前后即刻采用手持肌肉状态测试仪MyotonPRO对标记区域肌肉弹性、张力及硬度进行测量,并进行疼痛、踝背屈活动度测定,对数据进行t 检验分析处理。研究方案的实施符合河北师范大学的相关伦理要求,所有受试者均已签署知情同意书。
结果与结论:①与干预前比较,干预后肌肉张力振荡频率值显著降低(P < 0.05),硬度分值和肌肉弹性分值显著升高(P < 0.05);压痛区域疼痛目测类比评分显著降低(P < 0.05);踝背屈活动度显著改善(P < 0.05);②结果说明,足外翻激活干预即刻可降低肌肉张力及硬度,增强肌肉弹性,对改善运动疲劳、提升运动表现具有促进作用;通过交互抑制效应可降低疼痛分值,改善踝背屈活动度,对缓解疼痛症状、降低损伤风险具有潜在意义。

Abstract: BACKGROUND: Exercise for activating foot valgus muscle is an important intervention approach in the field of foot and ankle rehabilitation. It has been widely used in rehabilitation practice; however, its interactive effect on antagonist muscles is still unclear.
OBJECTIVE: To explore the reciprocal inhibitory effect of foot varus muscle activation exercise on antagonistic muscle.
METHODS: Eighteen college student volunteers were selected. The elastic band was used for the isometric exercises of foot eversion. Muscle elasticity, tension and hardness of the marked area were measured using MyotonPRO before and after the intervention, and pain intensity and ankle dorsiflexion activity were measured. The data were analyzed and processed by t-test. The implementation of the study protocol complied with the relevant ethical requirements of Hebei Normal University, and all subjects signed an informed consent form prior to the participation in the trial.
RESULTS AND CONCLUSION: After intervention, muscle tension oscillation frequency was significantly decreased (P < 0.05); the hardness score and muscle elasticity score were significantly increased (P < 0.05); the pain score in tenderness area was significantly lower (P < 0.05); and the dorsal malleolus flexion activity was significantly improved (P < 0.05). To conclude, foot varus activation exercises can immediately reduce muscle tension and hardness, enhance muscle elasticity, and improve exercise fatigue and performance. This reciprocal inhibitory intervention have a potential to reduce the pain score, improve ankle dorsiflexion range of motion, relieve pain, and reduce the risk of sports injury.
