The table displays the individual values of the iSP measures for each participant. The status is indicated by the participant’s ID (PVL= participant with bilateral spastic CP/PVL; CTR = control). The second column gives the individual’s age in years and additional months. Age differed between the matching partners from 0 to 9 months (median difference was 2mo). Resting motor threshold is given as the percentage of stimulator output. The latency and the duration of iSP are given in milliseconds (MS), the extent of iSP in qmm. – indicates that iSP could not be elicited. p-values are derived by calculating the Mann-Whitney U test. F=female, M=male.
