The aim of this study was the effect of internal and external attention on anticipatory motor plannig. in people with MS. Thirty patients with mean age of 34 (age mean= 34±2/43 , EDDS=4-6) with criteria for participation in the study. to prevent the effects of sequencing on task assignment to a subgroup The three focus groups were internal, external, and non-instructional. In this study, the Bar- transfer task was used for anticipatory motor planning. Interventions focused on the focus of attention on the thumb and on the external attention to the Bar. Analysis of variance with repeated measures was used to investigate the effect of different types of focus onanticipatory motor planning. The results showed that external focus in the Bimanual task led to an increase in comfortable end state and non-instructional effort resulted in better internal focus as well as Stroop test score, executive functions, and weksler test with most project conditions and assignments. There was a significant relationship between most conditions and assignments. Also, Pearson correlation coefficient test results showed that there is a significant negative relationship between Stroop test score and executive functions with predictive planning in two-handed and two-handed assignments in all attentional focus conditions, and also between the numbers of the number-calling test and the Predictive projection in the two-handed and two-handed assignments was significantly correlated across all attentional conditions.
