Introduction: Patients with stroke often face cognitive impairments, they may find explicit learning challenging. Implicit learning, which unfolds unconsciously, offers an alternative approach. Purpose: This systematic review aims to provide a comprehensive overview of the effects of implicit motor learning in stroke rehabilitation. Methods: Following the PRISMA guidelines, an electronic search was conducted across five databases for studies published between January 2000 and December 2023. Results: A total of 1,096 studies were initially identified, with nine RCTs and crossover trials meeting the inclusion criteria. Notably, six out of nine studies reported positive effects of implicit learning on motor performance compared to explicit learning. Most studies focused on chronic stroke patients, with interventions ranging from 3 to 4 weeks or assessing immediate effects. Conclusion: Implicit learning shows promise in enhancing motor performance in stroke patients. Therapists should tailor interventions to individual cognitive abilities to maximize the benefits of implicit learning.
