Negative values represent a decrease in the DC sorting position of the muscle in the hemiplegic group compared to the control group and positive values represent an increase in the DC position sorting

In simpler terms, negative values indicate that the muscle's sorting position in the hemiplegic group is lower than in the control group, suggesting a decrease in its performance. On the other hand, positive values indicate that the muscle's sorting position in the hemiplegic group is higher than in the control group, suggesting an improvement or increase in its performance.
