Background: Maintaining upright posture and balance is essential for all bipedal activities. Central nervous system in conjunction to peripheral nervous system, sensory system and neuromuscular system maintains the postural balance. The lower extremity kinetic chain plays a vital role in maintaining balance. Flat foot is one most common lower extremity malalignment. Abductor hallucis and gluteus maximus muscles are reported to control flatfoot. The aim of this study was to assess the effects of Gluteus maximus and Abductor hallucis muscle strengthening on balance in school going children with pronated foot. Material and Method: 40 healthy school going children of 7-10 years with either gender were selected on the basis of inclusion and exclusion criteria. Foot posture index and Pediatric berg balance (PBS) score were recorded prior and post exercise. Gluteus maximus and Abductor hallucis muscle strength training were prescribed for 5 days a week for 5 weeks. All variables were assessed post 5 weeks. Result: After the prescribed period of exercises, it became apparent that Foot FPI and PBS value scored significantly higher when analyzed using the paired t test at p≤0.05. Conclusion: Strengthening of Gluteus maximus and Abductor hallucis muscle has significant effect in improving balance in school going children with over pronated foot.
