Background:
Action observation combined with motor imagery (AO+MI) training is considered a potentially effective approach for improving motor function in patients after stroke. Therefore, it is important to review and analyze the existing research evidence of its effectiveness.
Objective:
This study aims to evaluate the effectiveness of AO+MI training on the limb motor function of patients with stroke.
Methods:
A systematic search was conducted in PubMed, Cochrane Library, Web of Science, Embase, Proquest, Physiotherapy Evidence Database, ClinicalTrials.gov, and ChiCTR. The last search was performed in June 2025. Three reviewers independently screened the articles, and 2 reviewers extracted data. Quality assessments of randomized controlled trials were done using the Cochrane Risk-of-Bias Tool. The certainty of evidence was evaluated with GRADEpro GDT (Evidence Prime, Inc). A meta-analysis was performed using RevMan 5.3 (The Cochrane Collaboration) software and Stata software.
Results:
A total of 13 articles were included with 399 patients with stroke. The results of the meta-analysis showed that compared with routine rehabilitation, AO+MI could improve the upper extremity function (standard mean difference [SMD]=1.02, 95% CI 0.28-1.75; P=.007) and the lower extremity function (SMD=6.31, 95% CI 4.75-7.87; P<.001) of patients with stroke. There was no significant difference between AO+MI and routine rehabilitation for improving activities of daily living (SMD=0.06, 95% Cl -0.35 to 0.47; P=.06). AO+MI could promote the recovery of upper extremity function in patients compared with MI independently (SMD=0.97, 95% Cl 0.13-1.80; P=.02). There was no significant difference between synchronous combination and asynchronous combination in upper extremity function rehabilitation of patients after stroke (SMD=-1.04, 95% Cl -2.56 to 0.48).
Conclusions:
AO+MI can improve the motor function of limbs and can be considered an effective limb rehabilitation therapy for patients after a stroke.
