The Effect of Core Stabilization Exercises on Upper Extremity Function and Balance in Children with Cerebral Palsy: A Randomized Controlled Trial

<b>Aim:</b> This study explores the effects of core stabilization exercises on balance and upper extremity functions-both unilateral and bilateral-in children with cerebral palsy (CP). <b>Method:</b> Thirty-six children with CP (aged 5-12) were randomly assigned to a study group (<i>n</i> = 18) or control group (<i>n</i> = 18). Both groups received four weeks of physiotherapy and occupational therapy. The study group additionally performed ~45 min of daily core stabilization exercises. Outcome measures included the Box and Block Test (BBT), Assisting Hand Assessment (AHA), Pediatric Berg Balance Scale (PBBS), and Trunk Control Measurement Scale (TCMS). (ClinicalTrials.gov ID: NCT06973213). <b>Results:</b> No significant baseline differences were found between the groups (<i>p</i> > 0.05). Post-intervention, the study group showed significant improvements in PBBS (<i>p</i> = 0.011), TCMS static sitting (<i>p</i> = 0.003), dynamic reaching (<i>p</i> = 0.037), and total score (<i>p</i> = 0.044). Between-group differences remained non-significant for BBT, AHA, and TCMS selective movement control (<i>p</i> > 0.05). Within-group analysis revealed significant gains in BBT (median = 7), PBBS (median = 8), TCMS total (median = 12), static sitting (median = 3.5), and selective movement (median = 6) (all <i>p</i> < 0.001). AHA showed a near-significant trend (median = 6, <i>p</i> = 0.051). <b>Conclusions:</b> Core stabilization exercises significantly enhance balance and unilateral upper extremity function in children with CP. However, they show limited impact on bimanual function. Integration of these exercises into rehabilitation programs may optimize motor outcomes.
