The primary aim of this review was to determine the effects of CIMT (constraint-induced movement therapy) on gait, balance, and motor functions of the lower extremity in stroke. The secondary aim was to determine the optimal dosage, application time, and duration of CIMT in the lower extremity in stroke. PubMed (1999-July 2021), Pedro (2000-December 2020), Google Scholar (1999-Febraury 2022), and Cochrane Library (2000-Febraury 2022) were searched in February 2022. The risk of bias was calculated through the criteria outlined in the (Cochrane-Handbook for Systematic-Reviews of Interventions). Eight RCTs were included in this review. CIMT was found to be effective in improving balance, gait, and motor functions of lower limbs; however, its superiority in comparison to the control group was not significant, no specific dosage was mentioned for lower limb CIMT as different studies used different durations and intensities of CIMT. Key Words: Cerebrovascular accident (CVA), Balance, Lower-extremity constraint-induced movement therapy (CIMT), Motor functions.
