DC使我们能够从肌肉的整体功能性协调中关注单一肌肉的作用。从均一化DC值结果来看下肢两侧肌肉均会受到脑卒中的影响但最终表现却不一样。患者患侧GM的DC值相较于非患侧值和健康人的相应值显著降低而患者非患侧GMA、GME和TA的DC值相较于患侧值及健康人的相应值则显著升高表2。除此之外我们还注意到DC值的排序结果与上述结果有异曲同工之妙表现为患者患侧的LO、GME、TA和GM的DC值排序显著降低非患侧

DC allows us to focus on the role of individual muscles in the overall functional coordination of muscles. From the homogenized DC value results, both sides of the lower limbs are affected by stroke, but the final performance is different. The DC value of the affected side GM is significantly lower compared to the unaffected side value and the corresponding value of healthy individuals, while the DC values of the unaffected side GMA, GME, and TA are significantly higher compared to the affected side value and the corresponding value of healthy individuals (Table 2). In addition, we also noticed that the sorting results of the DC values are similar, with the affected side LO, GME, TA, and GM having significantly lower DC values, and the unaffected side GMA, GME, and TA having significantly higher DC values (Fig. 5). These results indicate that stroke significantly affects the role of muscles in multi-muscle cooperation. The decrease in the synergistic action of the affected side hip and calf muscles is related to the lower level of neuromuscular control, which may be due to hemiplegia. A more interesting finding is that the sorting of the DC values of the affected side LO is significantly reduced, which is consistent with the results of previous studies that improving core muscles in hemiplegic patients can promote the recovery of motor function. The involvement and contribution of the unaffected side muscles, especially the hip and calf muscles, in maintaining standing balance are significantly increased, which may be due to compensation. Our study reaffirms the previous conclusion from the perspective of overall muscle dynamic coordination, that the unaffected side muscles are subject to more central regulation, showing a greater degree of activation and playing a more central role in upright posture control [35, 37, 38]. In future treatment and rehabilitation, the compensation of the unaffected side muscles with higher involvement should be reasonably eliminated or utilized. On the contrary, the muscles with lower involvement on the affected side deserve more consideration from clinical doctors, and their activation in motor control should be improved through relevant training
