Abstract

Introduction: Studies that have examined the upper limb function of children with cerebral palsy and hemiplegia have mostly used single-handed tasks, including the constraint of the healthy hand technique; however, this method led to emotional problems in the child. This study aimed to investigate hand function after bimanual handball training in children with hemiplegic cerebral palsy.
Methods: Five children referred to Fakhr e Sadegh Clinic with a mean age of 10.2±2.28 years were selected via convenience sampling. Parents of the children completed the consent form. Each participant was tested once before and once after the training using the Purdue pegboard test, and one-handed, simultaneous bimanual, and sequential bimanual performance were assessed. The participants performed two 30-minute bimanual exercise sessions per week for a total of six weeks.
Results: The results were analyzed using SPSS 27 software. Paired t-test showed that performance of the less affected hand (p=0.03) and sequential bimanual coordination (p=0.00) increased significantly, while simultaneous bimanual coordination (p=0.08) did not improve significantly. Also, the Wilcoxon test did not show a significant improvement in the more affected hand (p=0.06).
Conclusion: It seems that the use of bimanual handball catching exercises can be effective in improving sequential bimanual coordination and the function of the less affected hand in children with hemiplegic cerebral palsy and can be used as an intervention method in motor rehabilitation of these children.
