This study-A was to verify whether the EMS shoes act like a foot brace, and Study-B was conducted to examine the gait variables, fatigue, stress level and cytokine (inflammatory) response. The subjects of this study-A were only male students aged 20-23 who were enrolled in universities in D and C areas. The number of subjects was pre-estimated to be 42 people using the G*power3.1.9.4 program, and the same number of subjects was selected. It was divided into Control group (NEG n = 14), Foot Orthotics Group (FEG n = 14), and EMS Shoes Group (ESG n = 14). When the subjects of Study-A were classified by disease, 7 subjects with flat feet (Platypodia Group, PpG), 9 with Genu Varum (GvmG), and 11 with Genu Valgum (GvlG). They were classified according to method into Study-A and Study-B. The pre-test and post-test were conducted through body composition, blood sampling, and gait test in the same way, and exercise intervention was performed by wearing EMS shoes, except for the control group, NEG. This study-A verifies whether EMS shoes act like a foot brace, and study-B examines gait variables, blood fatigue, stress level, and inflammatory response when a walking exercise program after wearing EMS shoes was applied to patients with lower extremity deformity. To summarize the results of this study, the conclusion from Study-A was that it was verified that wearing EMS shoes had a corrective effect on the feet by further improving the gait process and reducing inflammatory response as well as systematic fatigue compared to wearing an orthotics or not. The conclusion from Study-B was that, when walking with EMS shoes, lower extremity deformity due to valgus improved the gait process more than flat foot or genu varum knee, and reduced overall fatigue as well as inflammatory response to some extent, so the stress level was significantly reduced was verified.
