We found that, in addition to severity, treatment and MEPs significantly influenced arm motor recovery over time. Patients who were allocated to RAT+FES reached a higher level of arm recovery (β=+5.93; P=.016) compared with ICT, considering same impairment level and MEPs; whereas patients with MEP+ obtained a greater arm recovery at 6-month follow-up (β=4.35; P=.011) (fig 4).
