Both underwent 20 one-hour sessions over 5 weeks. Participants of the experimental group observed goal-directed daily actions before replicating them in virtual reality, whereas participants of the control group viewed nature scenes before performing the same virtual reality tasks without action observation. Motor function was evaluated at baseline, postintervention, and 6-month follow-up using the Box and Block Test, with the primary estimand defined as the between-group difference in change in paretic hand scores. Secondary outcomes included measures of muscle strength, spasticity, global disability, and functional independence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>Both groups showed improvement in Box and Block scores for both hands. However, the experimental group demonstrated a greater gain in paretic hand function, with a between-group difference in change of 7.8 blocks at posttreatment (95% CI, 7.1\u20137.9) and 10.8 blocks at 6-month follow-up (95% CI, 10.6\u201310.9). Improvements in the nonparetic hand were comparable between groups. Similar improvements across both groups were observed in secondary outcome measures. A significant treatment\u00d7age\u00d7time-from-stroke interaction was observed for paretic hand dexterity, indicating that treatment effects varied according to these covariates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS:<\/jats:title>\n                    <jats:p>Action observation combined with virtual reality appears to be more effective than virtual reality alone for promoting upper limb motor recovery after stroke, particularly in enhancing fine motor function of the paretic hand.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>REGISTRATION:<\/jats:title>\n                    <jats:p>\n                      URL:\n                      <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/www.clinicaltrials.gov\">https:\/\/www.clinicaltrials.gov<\/jats:ext-link>\n                      ; Unique identifier: NCT05163210.\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1161\/strokeaha.125.054101","type":"journal-article","created":{"date-parts":[[2026,3,18]],"date-time":"2026-03-18T09:00:27Z","timestamp":1773824427000},"page":"1136-1148","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Action Observation Combined With Virtual Reality Promotes Motor Recovery After Stroke: A Randomized Controlled Trial"],"prefix":"10.1161","volume":"57","clinical-trial-number":[{"clinical-trial-number":"nct05163210","registry":"10.18810\/clinical-trials-gov"}],"author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0138-6369","authenticated-orcid":true,"given":"Antonino","family":"Errante","sequence":"first","affiliation":[{"name":"Department of Medicine and Surgery, University of Parma, Italy (A.E., C.R., S.Z., L.F.)."},{"name":"Diagnostic Department, Neuroradiology Unit, University Hospital of Parma, Italy (A.E., F.B.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donatella","family":"Saviola","sequence":"additional","affiliation":[{"name":"Centro Cardinal Ferrari KOS, Parma, Italy (D.S., M.C., K.I., C.M., D.
