Objective To evaluate the systematic reviews of efficacy ofconstraint-induced movement therapy (CIMT) in rehabilitation training for upper limb motor dysfunction in stroke patients, in order to provide more scientific and reliable evidence for the clinical rehabilitation of stroke. Methods Systematic reviews of the application of CIMT in patients with upper limb motor dysfunction after stroke was searched in domestic and foreign databases from the establishment to April 2024. The Risk of Biasin Systematic Review(ROBIS) scale, A measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2), Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 (PRISMA 2020) and Grading of Recommendations Assessment, Development and Evaluation System (GRADE) were respectively used to evaluate the risk of bias, methodological quality, reporting quality and evidence quality of the included studies. Results A total of 18 articles were included,and the methodological quality of 1 article was high, 1 article was medium, 10 articles were low, and the other 6 articles were very low. GRADE evidence quality evaluation involved 72 outcome indicators, in which 10 were of moderate quality, 32 were of low quality and 30 were of very low quality. CIMT has a positive impact on the rehabilitation of upper limb motor function, amount of use and quality of movement of the hemiplegic upper limb, and basic daily life of post-stroke patients,but in terms of disability and quality of life needs further research. Conclusion CIMT can effectively promote the recovery of upper limb motor function and daily living ability of stroke patients to a certain extent. However, the quality of the included systematic reviews is low, more high-quality studies are needed to further confirm the efficacy of CIMT in the rehabilitation of patients with upper limb motor dysfunction after stroke and provide strong evidence for clinical decision-making.
