招募在校就读健康男大学生并通过肩胛骨动力障碍测试（SDT）筛选受试者。对入选受试者开展肩胛骨上提、下降、前移、后缩、上回旋、下回旋运动实验，探究在开链、闭链条件下，肩胛骨各个方向运动时肩部肌群的积分肌电值（IEMG）、均方根振幅（RMS）、肌肉贡献率及肌群协同作用。结果表明：（1）肩上提运动中，闭链条件下上斜方肌（UT）、下斜方肌（LT）、三角肌后束（PD）、三角肌前束（AD）的激活程度显著低于开链条件（P<0.05）;(2)肩下降和前移运动中，闭链条件下LT、AD、PD、冈下肌（IS）的激活程度显著低于开链条件（P<0.05）;(3)肩后缩和肩上回旋运动中，闭链条件下PD、IS的激活程度极显著低于开链条件（P<0.01）;(4)闭链条件下，UT在肩上提、前移运动中的贡献率显著大于开链条件（P<0.05），而PD在肩前移、后缩运动中的贡献率显著低于开链条件（P<0.05）;(5)肩胛骨下降运动时，开链与闭链条件下UT∶MT、UT∶LT的比值均小于1。研究表明，开链条件（OKC）适用于肌力强化和针对性肌群激活，闭链条件（CKC）在改善肌群协同性（UT∶MT/LT<1）、减少代偿（PD抑制）和增强稳定性方面更具优势。
Abstract：Healthy male college students were recruited for the study, and subjects were screened using the Scapular Dyskinesis Test(SDT). Selected participants underwent experiments involving scapular elevation, depression, protraction, retraction, upward rotation, and downward rotation to investigate the IEMG, RMS, muscle contribution rates, and muscle group coordination of shoulder muscles during scapular movements in both open kinetic chain(OKC) and closed kinetic chain(CKC) conditions. The results are as follows.(1) During scapular elevation, the activation levels of the upper trapezius(UT), lower trapezius(LT), posterior deltoid(PD), and anterior deltoid(AD) under closed kinetic chains are significantly lower than those under open kinetic chains(P<0. 05).(2) During shoulder depression and protraction, the activation of LT, AD, PD, and infraspinatus(IS) under closed kinetic chains is significantly lower than that under open kinetic chains(P<0. 05).(3) During scapular retraction and upward rotation movements, the activation levels of the posterior deltoid(PD) and infraspinatus(IS) under closed kinetic chains are significantly lower than those under open kinetic chains(P<0. 01).(4) Under closed kinetic chains, the contribution rate of the upper trapezius(UT) during scapular elevation and protraction is significantly greater than that under open kinetic chains(P<0. 05), while the contribution rate of PD during shoulder protraction and retraction is significantly lower than under open kinetic chains(P<0. 05).(5) During scapular depression, the ratios of UT to middle trapezius(MT) and UT to LT under both open and closed kinetic chains are less than 1. The study indicates that open kinetic chains(OKC) are suitable for strength enhancement and targeted muscle activation, while closed kinetic chains(CKC) are more advantageous for improving muscle synergy(UT∶MT/LT<1), reducing compensation(inhibition of PD), and enhancing stability.
