NMES with corrective exercises improved standing foot alignment by static footprint analysis, while orthotic interventions enhanced radiological alignment (talus control insoles) and pain relief (traditional insoles) compared to conventional footwear. Outcome measurement differences between intervention types limited direct comparisons. Ten studies measuring gait, functional, or developmental outcomes were excluded due to insufficient outcome overlap.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
