Abstract
Background: School going children in the age group of 7-12 years have to spend long hours in sitting, and maintain adequate balance in order to use their upper limbs efficiently and functionally during play and in the performance of Activities of Daily Living (ADLs). Studies that have examined trunk control and the effect of underlying muscle tightness and spasticity that cause biomechanical constraints in children with Cerebral Palsy (CP) is scarce. Aim: This study aims to assess the effect of Hamstring muscle tightness on Sitting Balance in children with CP spastic diplegia. Materials and Methods: Thirty (30) children with CP spastic diplegia (n=30) belonging to GMFCS Levels I, II, and III, in the age group of 7-12 years, and thirty (30) age and sex-matched typically developing(TD) children were recruited for this study. Hamstring tightness was assessed by calculating the R2 angle using the modified tardieu scale. Pelvic tilt was measured in sitting using the pelvic inclinometer and sitting balance by Paediatric reach test & Trunk control measurement scale (TCMS). Centre of pressure excursion in forwarding direction was measured using the limits of stability protocol in sitting on the neurocom balance Master. Results: Children with CP spastic diplegia sat with a greater posterior pelvic tilt compared to TD children (p tilt in both groups of children (r value=0.6, p hamstrings spasticity with reach in forward as well as lateral directions (r value= 0.5, p tilt with reach in forward and lateral directions (r value = 0.6, p TCMS scores showed a moderate negative correlation with hamstrings tightness and posterior pelvic tilt (rho = 0.6). The maximum excursion of limits of stability showed a moderate negative correlation with hamstrings tightness and posterior pelvic tilt in the forward directions. Conclusion: Greater tightness of the hamstring muscles was associated with a posterior pelvic tilt and reduced sitting balance. Therapeutic interventions that manage hamstr

22 This interaction between the biomechanical and neural factors observed in this present study, as greater hamstrings muscle tightness was related to increased posterior pelvic tilt and impacting muscle recruitment and reduced functional sitting balance
Hamstrings tightness in children with Cerebral Palsy (CP) diplegia with increased posterior pelvic tilt, which in turn affects their sitting alignment/posture, sitting balance and hampers their prehensile and functional abilities
Summary
Aim: This study aims to assess the effect of Hamstring muscle tightness on Sitting Balance in children with CP spastic diplegia. There was a moderate positive correlation of hamstrings muscles tightness with posterior pelvic tilt in both groups of children (r value=0.6, p
