Core Strength for Head Control and Quality of Life in Cerebral Palsy

The goal of this observational study is to examine the effect of an 8-week therapist-assisted core muscle strengthening program on head control, trunk stability, functional core strength, quality of life, and automatic righting reactions in non-ambulatory children with spastic cerebral palsy. The main questions it aims to answer are: * Does head control improve over time in supine, prone, and supported sitting? * Does segmental trunk control improve across static, active, and reactive tasks? * Does functional cervico-trunk strength improve? * Do automatic righting reactions change after the intervention? Participants will: * Take part in 24 therapy sessions over 8 weeks. * Receive therapist-assisted core activation exercises such as bridging, modified quadruped over a bolster, supported sitting on a therapy ball with multidirectional perturbations, and assisted pull-to-sit. * Complete assessments at baseline, week 4, and week 8 for head control, trunk control, functional strength, and righting reactions. Researchers will compare participants' outcomes across baseline, mid-intervention, and post-intervention time points to see whether the program is associated with improvements in motor control and function.
