In a double-blind randomized controlled trial, 112 patients with hemiplegia after stroke were randomly divided into two groups: experimental and control. In experimental group, the patients received LF r TMS and VR training treatment, and those in control group received sham r TMS and VR training treatment. Participants in both groups received therapy of 6 days per week for 4 weeks. The primary endpoint including the upper limb motor function test of Fugl-meyer assessment(U-FMA) and wolf motor function test(WMFT), and the secondary endpoint including modified Barthel index(MBI) and 36-item Short Form Health Survey Questionnaire(SF-36) were assessed before and 4 weeks after treatment. Totally, 108 subjects completed the study(55 in experimental group and 53 in control group respectively). After 4-week treatment, the U-FMA scores [mean difference of 13.2, 95% confidence interval(CI) 3.6 to 22.7, P〈0.01], WMFT scores(mean difference of 2.9, 95% CI 2.7 to 12.3, P〈0.01), and MBI scores(mean difference 16.1, 95% CI 3.8 to 9.4, P〈0.05) were significantly increased in the experimental group as compared with the control group. The results suggested the combined use of LF r TMS with VR training could effectively improve the upper limb function, the living activity, and the quality of life in patients with hemiplegia following subacute stroke, which may provide a better rehabilitation treatment for subacute stroke.展开更多

Methods The largest N20-P25 response was recorded from postcentral gyrus by intraoperative monitoring of cortical motor evoked potentials in 10 patients with intracranial lesions near or in the central area. The muscles of upper extremity in all patients were activated by delivering stimulus to cortical areas continuously. Moving the cortical electrodes forward, the largest P20-N25 response, SEP phase reversal,was obtained as a motor center stimulus. In this site of cortex, a short train stimulation elicited reproducible muscle action potentials that could be observed from the oscilloscope without averaging.Results MEPs can be recorded, pre-and post-operatively, without motor deficits of upper limbs in all patients.Conclusion This technique seems to be preferable for intraoperative localization of motor evoked potentials in central sulcus lesions under total intravenous anesthesia.展开更多
