Method : The search strategy was built on five databases: PubMed, Embase, Cochrane Library, SportDiscus and ClinicalTrials.gov. Only RCT in French or English corresponding to the PICOS criteria were included in this systematic review. Results : 14 articles out of 2285 were included in this systematic review. There is a favorable trend towards the use of strengthening protocols for the intrinsic foot muscles to increase their size and improve dynamic balance, foot rigidity and foot posture. With regard to strength measured on a dynamometer, the results are more mixed, with only one article in favor of intrinsic foot muscles strengthening. Conclusion : The clinical implications of the different results obtained in this systematic review are difficult to determine given the differences in protocols and populations. This is why it would be interesting in the future to carry out more studies on the subject with a uniformity of protocols and study populations.intrinsic foot musclesfoot coreminimalist shoesstrengthsizenavicular drop testfoot posture indexbalancetext::thesis::master thesisthesis:42028
