Objective To explore the effective method at different times of the early treatment of acupuncture and rehabilitation therapy on motor dysfunction after cerebral infarction. Methods According the course of disease ,97 patients with motor dysfunction after cerebral infarction were divided into two groups:the observation group (48h after onset) and the control group(48h after stable vital signs). The two groups were given to the same acupuncture and rehabilitation treatment at 48h after onset and stable vital signs using 48h after respectively in the premise of conventional treatment. The treatment outcomes after three courses were compared,and each course was 7 ～ 10d. Results The Fugl-Meyer motor function score and FMA motor dysfunction assessed in the observation group were better than that in the control group (P <0.01, P < 0.05 ). Conclusion The acupuncture and rehabilitation treatment for motor dysfunction after cerebral infarction at 48 h after onset was better than that at 48h after stable vital signs.

In order to more accurately and effectively understand the intermuscular coupling of different temporal and spatial levels from the perspective of complex networks, a new multi-scale intermuscular coupling network analysis method was proposed in this paper. The multivariate variational modal decomposition (MVMD) and Copula mutual information (Copula MI) were combined to construct an intermuscular coupling network model based on MVMD-Copula MI, and the characteristics of intermuscular coupling of multiple muscles of upper limbs in different time-frequency scales during reaching exercise in healthy subjects were analyzed by using the network parameters such as node strength and clustering coefficient. The experimental results showed that there are obvious differences in the characteristics of intermuscular coupling in the six time-frequency scales. Specifically, the triceps brachii (TB) had relatively high coupling strength with the middle deltoid (MD) and posterior deltoid (PD), and the intermuscular function was closely connected. However, the biceps brachii (BB) was independent of other muscles. The intermuscular coupling network had scale differences. MVMD-Copula MI can quantitatively describe the relationship of multi-scale intermuscular coupling strength, which has good application prospects.
