During the acute phase (first seven days), a critical neuroplastic window exists where interventions may significantly influence recovery. This systematic review and meta-analysis aimed to evaluate the effectiveness and safety of electrical stimulation\u2014specifically Functional Electrical Stimulation (FES) and Neuromuscular Electrical Stimulation (NMES)\u2014on upper limb functional recovery and complication prevention during the acute phase of stroke. Methods: A systematic search was conducted across eight databases (including Medline, PEDRo, and Cochrane) for randomized and non-randomized clinical trials published between 2016 and 2025. Methodological quality was assessed using the PEDRo scale. Quantitative synthesis was performed via meta-analysis using a random-effects model, focusing on the Fugl-Meyer Assessment (FMA-UE). Results: Eight randomized clinical trials were selected with a total of 384 participants. The meta-analysis results showed a positive and statistically significant effect in favor of the experimental group compared to the control group (Z = 2.39; p = 0.02), with a combined Standardized Mean Difference of 0.53 (95% CI: 0.10 to 0.96), indicating a moderate effect size on the Fugl-Meyer Assessment Upper Extremity scale. Although high heterogeneity was detected (I2 = 74%), the analysis suggests that Functional Electrical Stimulation (FES) and Neuromuscular Electrical Stimulation (NMES) improve manual dexterity, prevent disuse atrophy, and reduce glenohumeral subluxation. Conclusions: Electrical stimulation shows a positive trend in early stroke recovery; however, it should be considered a promising adjunct rather than a definitive treatment. Further research into standardized protocols is required to confirm their clinical significance.<\/jats:p>","DOI":"10.3390\/neurolint18050091","type":"journal-article","created":{"date-parts":[[2026,5,25]],"date-time":"2026-05-25T08:06:26Z","timestamp":1779696386000},"page":"91","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Effectiveness of Electrical Stimulation on Upper Limb Function During the Acute Phase of Stroke: A Systematic Review and Meta-Analysis"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1684-1416","authenticated-orcid":false,"given":"Sagrario","family":"P\u00e9rez-de la Cruz","sequence":"first","affiliation":[{"name":"Department of Nursery, Physiotherapy and Medicine, University of Almer\u00eda, 04120 Almer\u00eda, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,13]]},"reference":[{"key":"ref_1","unstructured":"World Stroke Organization (WSO) (2022).
