To target specific cervical segments (Figure 1A), an electrode configuration of 1 x 3 (Figure 1B) was used wherein stimulation was provided simultaneously to 3 adjacent electrodes within a single row, spanning the midline. The sensors used were calibrated at regular intervals using standard weights (Supplementary Figure S1).
Increase in muscle activity and force after tSCS. (A) The force generated by the left D1 IP joint in case of participant CTS01. * indicates a significant difference (Two-sample t-test with Bonferroni correction for multiple comparisons). (B) The AUC of the EMG activity recorded from the left APB muscle during the task of force generation using the D1 IP joint.
