Summary

Ischemic stroke, the most prevalent neurological disorder, is treated with medication and thrombectomy but with limited success, especially in chronic stages where traditional rehabilitation is the primary option. Stroke often leads to post-stroke autonomic imbalance, deteriorating functional outcomes and increasing recurrence risk. Emerging non-pharmacological treatments like Transcutaneous Auricular Vagus Nerve Stimulation (VNS) and Focused Transcranial Direct Current Stimulation (tDCS) offer new possibilities. VNS targets post-stroke tissue injury and promotes healing and neurogenesis, while tDCS aims to enhance motor learning by rebalancing brain activity. Both therapies seek to improve outcomes in both acute and chronic stroke stages.

Conditions

Interventions

DEVICE

tDCS stimulation

tDCS 1mA will be applied for 20min. tDCS will be applied around the infract area. taVNS or sham taVNS wil be applied before tDCS. The intervention will be applied before physical therapy. A total of 10 sections are applied during the intervention period of 2 weeks.

DEVICE

taVNS stimulation

taVNS will be applied for 30 min. The electrode will be placed on the left ear of the patient. The amplitude of taVNS will be adjusted under the patient's pain threshold. After taVNS, tDCS will be applied for 20 min. The intervention will be applied before physical therapy. A total of 10 sections are applied during the intervention period of 2 weeks.

DEVICE

sham tDCS stimulation

sham tDCS 1mA will be applied for 20min. sham tDCS will be applied around the infract area. The stimulation will be applied for only 10 seconds and no stimulation afterward. taVNS or sham taVNS wil be applied before sham tDCS.The intervention will be applied before physical therapy. A total of 10 sections are applied during the intervention period of 2 weeks.

DEVICE

sham taVNS stimulation

sham taVNS will be applied for 30 min. The electrode will be placed on the left ear of the patient. The amplitude of sham taVNS will be adjusted under the patient's pain threshold. The stimulation was only applied for 5 seconds and no stimulation afterward. After sham taVNS, tDCS or sham tDCS will be applied for 20 min. The intervention will be applied before physical therapy. A total of 10 sections are applied during the intervention period of 2 weeks.
