Improving the Function of the Foot by Core Foot System (CFS) Exercise Theory in Patients After Hallux Valgus Surgical Procedure

Study Overview
=================
Brief Summary
-----------------
The aim of the study is to identify the impact of CFS foot muscle training on time-space parameters, anthropometric parameters and bioelectrical activity (EMG) of the foot muscles during walking and to develop an algorithm for an effective therapeutic method in patients after hallux valgus correction. Achieving the purpose of the research will contribute to the answer to the following research questions: Does the CFS therapy used significantly change the arch of the foot in HV patients compared to the control group? Does the CFS therapy used significantly improve gait characteristics after HV surgery in relation to the control group? Does muscle stimulation and the moment of their activation differ in groups in which different therapies have been used? Will the results of the questionnaires and scale be significantly different in both groups?
