Immediate Effects of Plantar Fascia Release Combined With Foot Exercises on FMS Subscores in Young Adults With Pes Planus

This randomized crossover clinical study aims to investigate the immediate effects of plantar fascia release combined with foot exercises on Functional Movement Screen sub-scores in physically active young adults with pes planus. Participants aged 18-35 years with pes planus, determined by the Navicular Drop Test, will complete two different intervention protocols in a randomized order. Protocol A will include foot-core exercises combined with plantar fascia stretching. Protocol B will include the same foot-core exercises and plantar fascia stretching, with the addition of plantar fascia myofascial release. Each participant will receive both interventions on separate sessions, with a 24-hour washout period between sessions. Functional movement quality will be assessed using two Functional Movement Screen subtests: Deep Squat and Hurdle Step. These tests will be performed before and after each intervention session to evaluate acute changes in movement performance. The main hypothesis of the study is that plantar fascia myofascial release combined with foot-core exercises and plantar fascia stretching will produce greater immediate improvements in Functional Movement Screen Deep Squat and Hurdle Step scores compared with foot-core exercises and plantar fascia stretching alone.
