Figure 4From: Effects of early and intensive neuro-rehabilitative treatment on muscle synergies in acute post-stroke patients: a pilot studyMetrics to compare weight coefficients. Mean and standard deviation of the metric adopted to describe intra-group (i.e., dot intra ) and inter-groups (i.e., dot inter ) similarity between homologous synergies. Labels on the horizontal axis refer to: 0 w, pre treatment; 2 w, 2 weeks; 4 w, 4 weeks; 6 w, post treatment. The label * highlights when values for post-stroke subjects are significantly different from healthy control group (p < 0.05).Back to article page
