【摘要】：研究目的:研究核心稳定性训练对上肢过顶项目运动员肩胛骨动力障碍康复效果的影响,包括肩胛带肌肉的激活程度和活动比率、肩胛骨静态位置、肩关节功能的变化,为上肢过顶运动员肩胛骨动力障碍的康复提供新思路和方法。研究方法:将肩胛骨动力障碍上肢过顶项目运动员24名,随机分成肩加核心组E组及肩组C组。C组进行单纯肩胛带训练,E组则在每次肩胛带训练之前均加入核心稳定性训练。训练5周前后测试肩胛系数SI、肩胛骨外侧滑动测试LSST、肩胛带肌肉在上肢过顶动作中激活程度(肌肉募集程度百分比MVC%和均方根肌电RMS)、肌肉平衡比率(UT/MT、UT/LT、UT/SA)、肩关节功能指标(DASH、Y-Balance)、核心稳定性,进行组内及组间差异性分析,比较两组治疗效果。研究结果:与训练前相比,1.两组SI均显著升高,组间无显著性差异;两组LSST中肩关节外展90°位外侧滑移显著减少。2.肩胛带肌电指标:(1)两组UT在W动作中的激活程度显著下降;两组MT在T动作中、LT在Y动作中、SA在推肩俯卧撑上升阶段的激活程度均显著提高;且E组SA在推肩俯卧撑上升阶段的激活程度显著高于C组。(2)肩关节屈曲和D2动作中,两组UT激活程度均显著降低,E组UT的激活程度显著低于C组;两组LT激活程度显著升高,且E组LT的激活程度显著高于C组,E组UT/LT、UT/SA显著低于C组。(3)在肩关节外展中,两组UT激活程度均显降低;两组LT激活程度升高,且E组显著高于C组;E组SA的MVC%显著升高;E组UT/MT、UT/LT显著低于C组。3.肩关节功能指标:(1)两组DASH得分均显著降低,且E组体育模块得分显著低于肩组。(2)E组Y-Balance得分显著升高,且显著高于C组,E组外上线距离显著增加。4.核心稳定性:E组核心稳定性显著提高,且显著高于C组。研究结论:上肢过顶运动员肩胛骨动力障碍康复中,核心稳定性训练的加入可降低上肢过顶动作中UT的激活程度,提高LT的激活程度,降低UT/LT及UT/SA肌肉活动比率;改善肩胛骨的异常位置,提升肩关节功能状态。
[Abstract]:Objective: to study the effect of core stability training on the rehabilitation effect of scapular dynamic disorder in upper extremity athletes, including the activation degree and activity ratio of scapular muscles, the static position of scapula, and the changes of shoulder joint function. To provide new ideas and methods for the rehabilitation of scapular dyskinesia in upper limb overtopping athletes. Group E was randomly divided into shoulder plus core group E and shoulder group C. C for simple scapular band training. Group E was given core stability training before and after each scapular band training. The scapular coefficient SIand lateral scapular slippage were measured before and after 5 weeks of training. Motion test LSST, the degree of activation of scapular muscles over the top of the upper limb (percentage of muscle recruitment degree MVC% and RMSM, muscle balance ratio of UTR / MTUTR / LTT / SAA, shoulder joint function index DASHY-Balancex, core stability, etc. The results showed that the SI of the two groups was significantly higher than that of before training, but there was no significant difference between the two groups. The lateral slip of 90 掳abduction of shoulder joint was significantly decreased in LSST group. The activation degree of UT in W motion was significantly decreased in two groups (EMG index of scapular band: 1). In both groups, the activation of LT in Y motion was significantly higher than that in group E, and the activation degree of SA in group E was significantly higher than that in group C and group D 2. The activation degree of UT in group E was significantly lower than that in group C, and the activation degree of LT in group E was significantly higher than that in group C (P < 0.05), and the level of activation of LT in group E was significantly higher than that in group C (P < 0.05), and the degree of activation of LT in group E was significantly higher than that in group C (P < 0.05). The level of UT activation in group E was significantly lower than that in group C (P < 0.05). The DASH score of group E was significantly higher than that of group C (P < 0.01), and the MVC% of group E was significantly higher than that of group C (P < 0.05), and the score of DASH in group E was significantly lower than that in group C (P < 0.05), and the score of DASH in group E was significantly lower than that in group C (P < 0.05). The score of sports module in E group was significantly lower than that in shoulder group. The score of Y-Balance in group E was significantly higher than that in group C. 4. The core stability of group E was significantly higher than that of group E, and the core stability of group E was significantly higher than that of group E. Conclusion: the addition of core stability training can reduce the activation of UT and increase the activation of LT. Reduce the ratio of UT/LT and UT/SA muscle activity, improve the abnormal position of scapula, improve the function of shoulder joint.
