Changes in brain response after transcranial electrical stimulation in stroke patients

Official title: Changes in Hemodynamic Response Following Transcranial Electrical Stimulation in Sroke Individuals

Run by Mahidol University · NCT07433972 · Data updated 2026-11-12

This study tests whether transcranial electrical stimulation added to rehabilitation can alter brain blood flow and oxygen use in adults who have had a stroke, from subacute to several years post-stroke.

Is this trial a fit for you?

Likely a good fit

Adults 18-80 years with a first-ever unilateral stroke 2 weeks to 5 years prior, able to walk with or without aids, and MoCA-T ≥ 20.

Probably not a fit

Individuals with unstable medical conditions, certain implanted devices, or contraindications to non-invasive brain stimulation may not benefit.

What this trial studies

This interventional study combines transcranial direct current stimulation (tDCS) or transcranial alternating current stimulation (tACS) with conventional physical therapy and cognitive-motor dual-task gait training. Participants include adults aged 18-80 with unilateral stroke occurring 2 weeks to 5 years prior, able to walk with or without aids, and with adequate cognitive function. Hemodynamic changes in the brain will be measured using functional near-infrared spectroscopy (fNIRS) to assess oxy- and deoxyhemoglobin during rehabilitation tasks. The study aims to understand how tES modalities influence cerebral blood flow and oxygen consumption when paired with rehabilitation in subacute to chronic stroke survivors.

Why it matters

Potential benefit: If successful, the approach could improve brain function and potentially enhance motor and cognitive recovery after stroke when paired with rehab.

How similar studies have gone: Previous research suggests that combining non-invasive brain stimulation with rehabilitation can yield functional and neurophysiological benefits in stroke care, though specific fNIRS-based hemodynamic changes with tES are less established.
