PMID 41144624WHAT IT FOUND
Adding action observation with motor imagery to routine rehab improved upper limb function scores, but did not improve daily self-care.
The evidence is low quality from small trials, so treat this as a potential add-on rather than a proven replacement for standard therapy.
Key findings
01Compared to routine rehabilitation alone, the combined intervention significantly improved upper extremity function (SMD 1.02, 95% CI 0.28 to 1.75).
02The intervention did not significantly improve activities of daily living compared to routine rehabilitation (SMD 0.06, 95% CI -0.35 to 0.47).
03There was no significant difference in upper extremity function outcomes between synchronous and asynchronous delivery modes.

What it does not show
The included studies were mostly small trials, leading to imprecise results. Many studies had a high risk of bias, particularly in how participants were randomized and whether staff were blinded. Interventions varied widely, with some studies mixing AO+MI with other therapies like mirror box therapy, making it hard to isolate the effect of the combined mental practice. The overall certainty of the evidence was rated as low to very low. Only English-language publications were included, potentially missing relevant data.
Declared interests
The authors declared no conflicts of interest.
The easy way to misread this
Do not assume that improved test scores for arm movement mean the patient will function better in daily life. The study found a significant gain in upper limb function metrics but no significant improvement in activities of daily living, meaning the clinical benefit for independence remains unproven.
