Background: 85% of multiple sclerosis patients suffer from impaired motor function and 65% from cognitive impairment. Therefore The main purpose of this study is to improve the cognitive and motor function of patients using dual tasks.Methods: The study samples were 60 women with MS (20-50 years) with an Expanded Disability Status Scale 2-4 and the duration of the period (10-14 years) who were divided into 4 groups and for eight weeks each week including two sessions 45 They practiced dual cognitive, motor, and individual training for 45 to 60 minutes. Data were analyzed by composite variance analysis at significance level of P <0.05.Results: The results of compound analysis analysis showed that the training of cognitive-motor tasks improved the significance of motor function (p = 0.0005) and cognitive performance (p = 0.0001) compared to the other three groups.Conclusion: The results of this study suggest that the physical benefits of training are always superior to cognitive changes. Dual-task training can be considered a good way to improve cognitive and cognitive function.Trial registration: This study was registered in the Iranian Clinical Trial Center with the number IRCT20200812048384N1, http://www.irct.ir/trial/50300, registered 26 August 2020.
