Noninvasive brain stimulation leads to fine motor improvement after stroke, shows study.

‘Non-invasive brain stimulation may have beneficial effects on fine motor movement in stroke patients.’

The investigators observed statistically significant gains in fine motor movement in stroke patients following tDCS and TMS; however, time since onset of stroke event, the severity of impairment, combination of non-invasive brain stimulation with other interventions, and risk of bias were all relevant factors. Fine motor improvement in healthy participants' non-dominant hand (a surrogate to an impaired hand) was also observed. 




"Encouragingly, research to refine these gains, understand their impact on lifestyle, and determine best responders to these types of treatments is happening now," said lead author Dr. Anthony O'Brien, of the Spaulding Neuromodulation Center, an affiliate of Harvard Medical School.
