Parameters were considered abnormal when their value fell outside the 95% confidence interval recorded in the healthy controls.
cSP1, contralateral early silent period; cSP2, contralateral late silent period; iSP1, ipsilateral early silent period; iSP2, ipsilateral late silent period; N, normal values; T0, baseline assessment; T2, 20-month follow-up; ↑, increased values; ↓, reduced values.
