The purpose of this study was to compare upper limb function and quality of life in preschool children with complications of birth injuries to the cervical spinal cord and spine. Research methods: the study used a clinical neurological examination and the results of the Pediatric Outcomes Data Collection Instrument (PODCI) scale, neurofunctional (electroneuromyography - ENMG), neuroimaging (ultrasound - ultrasound of the cervical spinal cord and spine) research methods. Results and discussion. Upper extremity dysfunction is an area that primarily reduces quality of life in children with HSDD. This result highlights how difficult it is to manipulate objects with the upper limbs during certain activities, such as lifting heavy books, pouring milk, opening a previously opened can, using cutlery, combing hair, buttoning clothes, putting on a coat, and writing with a pencil. All of these may be related to the limited range of motion in these children, which is impaired by muscle weakness, simultaneous activation of antagonists, differences in the length of the affected limb, and contractures. Subsequently, children with HSDD demonstrate limitations in performing functional tasks that are necessary for independence in daily activities and quality of life, as well as tasks requiring fine motor skills. Conclusion. Thus, the quality of life of preschool children before treatment was reduced on all scales. When the results for each domain were analyzed separately, both groups showed poor results in the domain that reflects hand activity among all domains. Impaired hand function is the main area that reduces the quality of life in children with complications of PTSD. This domain has the lowest score compared to other domains, which has also been confirmed by other studies. As a result of the course of rehabilitation measures, a positive statistically significant dynamics of quality of life indicators was noted
