Condition(s) studied

Investigational drug(s) / intervention(s)

High-Frequency1: rTMS intervention: 20 sessions of 10-Hz rTMS at 90% resting motor threshold (RMT), 50 pulses per session with a 25-second interval between sessions, totaling 1,000 pulses. rTMS target: ipsilateral primary motor cortex. Total rTMS sessions: once a day, 5 days per week, for 2 weeks, totaling 10 sessions. Additional treatment: inpatient conventional rehabilitation therapy, consisting of occupational and physical therapy for 30 minutes each, twice daily, for 2 weeks, as well as the routine pharmacotherapy based on the guidelines for management of patients with stroke.

cTBS1: rTMS intervention: 40 seconds of cTBS at 70% RMT, totaling 600 pulses. rTMS target: contralateral primary motor cortex. Total rTMS sessions: once a day, 5 days per week, for 2 weeks, totaling 10 sessions. Additional treatment: inpatient conventional rehabilitation therapy, consisting of occupational and physical therapy for 30 minutes each, twice daily, for 2 weeks, as well as the routine pharmacotherapy based on the guidelines for management of patients with stroke.

High-Frequency2: rTMS intervention: 20 sessions of 10-Hz rTMS at 90% RMT, 50 pulses per session with a 25-second interval between sessions, totaling 1,000 pulses. rTMS target: ipsilateral premotor cortex. Total rTMS sessions: once a day, 5 days per week, for 2 weeks, totaling 10 sessions. Additional treatment: inpatient conventional rehabilitation therapy, consisting of occupational and physical therapy for 30 minutes each, twice daily, for 2 weeks, as well as the routine pharmacotherapy based on the guidelines for management of patients with stroke.

Study summary

The objective of this study was to determine the effects of protocols of repetitive transcranial magnetic stimulation (rTMS) therapy based on the functional reserve of each hemiplegic stroke patient in subacute phase, compared to conventional low-frequency rTMS therapy on contralateral M1. Investigators hypothesized that the functional reserve of each hemiplegic stroke patient will be different, and therefore an appropriate simulating target for rTMS therapy is needed. In addition, this approach could be more effective compared to conventional protocols applied to stroke patients regardless of their severity, predicted mechanism of motor function recovery, or functional reserves.
