Outcome Measures

Primary Outcomes (2)

  • Fugl-Meyer Assessment for Upper Extremity

    It is considered as gold standard and is the only impairment level measure recommended for stroke trials. It consists of 30 items assessing motor function and 3 items assessing reflex function. The score most applicable to task performance is given from "0, inability," "1, beginning ability," to "2, normal" (total score range, 0-66).

    Change from Baseline Fugl-Meyer Assessment for Upper Extremity at 4 weeks and 12 weeks

  • Stroke-Specific Quality of Life Scale

    The Stroke-Specific Quality of Life Scale assesses health-related quality of life specific to stroke survivors. 49 questions under 12 subscales. Scores range from 49-245. Higher scores indicate better functioning.

    Change from Baseline Stroke-Specific Quality of Life Scale at 4 weeks and 12 weeks

Secondary Outcomes (5)

  • Barthel Index

    Change from Baseline Barthel Index at 4 weeks and 12 weeks

  • Modified Ashworth Scale

    Change from Baseline Modified Ashworth Scale at 4 weeks and 12 weeks

  • Berg Balance Test

    Change from Baseline Berg Balance Test at 4 weeks and 12 weeks

  • Composite Autonomic Symptom Score (COMPASS-31)

    Change from Baseline Composite Autonomic Symptom Score at 4 weeks and 12 weeks

  • Pittsburgh Sleep Quality Index

    Change from Baseline Pittsburgh Sleep Quality Index at 4 weeks and 12 weeks

Device: Sham stimulation

Interventions

In addition to the conventional rehabilitation program, non-invasive vagus nerve stimulation will be applied to the participants through the left ear with the Vagustim™-Ear tens electrode. As a vagus stimulation protocol, 10 sessions, 30 minutes, noninvasive auricular stimulation will be applied, stimulation frequency is 10 Hz, pulse width is 300 µs, and biphasic.

Active Stimulation for left hemiparesis patientsActive Stimulation for right hemiparesis patients

In addition to the conventional rehabilitation program, sham vagus nerve stimulation (0 mA) will be applied to the participants in the control group. Non-invasive vagus nerve stimulation will be applied to the participants through the left ear with the Vagustim™-Ear tens electrode. As a vagus stimulation protocol, 10 sessions, 30 minutes, and noninvasive auricular stimulation will be applied.

  • Severe depression (Beck Depression Scale \> 29)
  • Current use of any other stimulation device, such as a pacemaker or other neurostimulator; current use of any other investigational device or drug.
  • Medical or mental instability (diagnosis of personality disorder, psychosis, or substance abuse) that would prevent the subject from following the protocol timeline.
  • Pregnancy or planning to become pregnant or breastfeed during the study period.
  • Botox injections or hemiplegia rehabilitation within 6 months before treatment.
  • Having a history of hemorrhagic stroke
  • Presence of ongoing dysphagia or aspiration difficulties.
