Analyzing Muscle Coordination in Stroke Patients: A Weighted Recurrence Network Approach

The objective of this study was to assess the coordination of multiple muscles involved in postural control during standing and to identify any abnormal muscle function resulting from stroke. To achieve this, a weighted recurrence network (WRN) was constructed to analyze the dynamic coordination of the muscles responsible for maintaining balance during standing. The DC was used to determine the contribution of specific muscles in the WRN. The study aimed to test the hypothesis that stroke would alter the dynamic coordination patterns involved in postural control and that the responsible muscles for impaired coordination could be identified using this innovative method.
