简要总结
Post-stroke motor recovery is compelling but limited. Current rehabilitation has less impacts on the plateau that spontaneous biological recovery could be expected. The advances in non-invasive neuromodulation and neurophysiological characterization of critical motor recovery period enable breaking the proportional recovery limitation. Our pilot studies demonstrated the safety and responsiveness of combing dual transcranial direct current stimulation (tDCS) and motor training in subacute stroke patients. There is also strong evidence that selective serotonin reuptake inhibitors (SSRIs) can substantially increase the effects of tDCS and improve motor function after stroke, even in the absence of depression. This proposal aims to prove the potential of combining of tDCS and the commonly used SSRI citalopram to improve response to a daily motor training intervention in acute stroke patients (Co-STARS trial).
详细描述
This is a randomized, double-blind, sham-controlled study in 80 patients with first-ever, unilateral, subcortical ischemic stroke 0.5-4 weeks after stroke onset with moderate to severe hemiparesis. Participants were randomized into four groups underwent either real dual tDCS [ipsilesional primary motor cortex (M1) anodal stimulation and contralesional M1 cathodal stimulation; 2 mA for 20 mins; 10 sessions within 2 weeks] with citalopram or placebo, or sham stimulation with citalopram or placebo. All will receive concurrent hospitalized intensive rehabilitation of 2 daily sessions of 90-minute physiotherapy. Action reach am test (ARAT), Fugl-Meyer Assessment (FMA), multimodality MRI and EEG will be measured at baseline and after 2 weeks' tDCS modulation. The primary outcome is the ARAT at 3 months after intervention. The combination of tDCS and a SSRI will be expected to improve response to motor training more effectively than either intervention alone. The enhanced responsiveness will be correlated or predicted by biomarkers from multimodality MRI or EEG.
