Table 3 Summary of clinical studies on post-stroke patients using tACS.
| Study | No. | Targeted lesion | Study design | Frequency | Peak current intensity | Location | Schedule | Follow-up | Outcomes |
|---|---|---|---|---|---|---|---|---|---|
| Gall et al, 2015 []68 | 20 (20) | Unilateral occipital stroke | RCT | 30 Hz | 1.5 mA | Frontal pole midline point | 20 min daily for 10 days | 2 months | Visual field change positively |
| Wu et al, 2016 []66 | 60 (30) | Subacute stroke | RCT | 20 Hz | 400 μA | bilateral mastoids | 30 min daily for 3 weeks | N/A | NIHSS and the TCD parameters (MFV, PI) in MCAs, ACAs, and PCAs positive |
| Räty et al, 2021 []67 | 9 (9) | Hemianopia after chronic stroke | RCT | 5–15 Hz | 1.5 mA | Bilateral frontal pole | 30 min during days 1–5 and 40 min during days 6–10 | 2 months | No difference in the median detection accuracy |
| NIHSS – NIH Stroke Scale; TCD – Transcranial Doppler; MCA – middle cerebral artery; ACA – anterior cerebral artery; PCA – posterior cerebral artery; MFV – mean flow velocity; PI – pulsatility index. | |||||||||
