This study describes a single pediatric case with hemiparesis who received a specialized physiotherapy intervention based on the Vojta method. The child, aged 15 years, was treated in a clinical setting by a physiotherapist certified in Vojta therapy during one intensive treatment session. Upper limb function was evaluated before and after the intervention using the Box and Block Test, as well as electroencephalography (EEG) and electromyography (EMG) recordings to explore changes in motor control and brain activity. The main purpose of this study is to document the feasibility and short-term effects of a Vojta-based physiotherapy session on upper limb function and neurophysiological parameters in a child with hemiparesis

This single-case clinical study involves a 15-year-old child with hemiparesis who underwent a physiotherapy intervention using the Vojta method in an outpatient clinic. The intervention consisted of one intensive treatment session delivered by an experienced physiotherapist specialized in Vojta therapy, following standardized stimulation patterns tailored to the patient's motor profile. Upper limb function was assessed immediately before and after the intervention using the Box and Block Test, while simultaneous EEG and EMG recordings were obtained to characterize cortical and muscular activation during motor tasks. The primary objective is to evaluate short-term changes in manual function, and the secondary objective is to describe associated neurophysiological changes, to generate hypotheses for future clinical trials in pediatric patients with hemiparesis.

Inclusion Criteria:

• Hemiparesis, 0-16 years, cognitive ability to perform the Box and Block Test

Exclusion Criteria:

• Severe musculoskeletal deformities or pain in the upper limb that prevent the performance of the Box and Block Test, Severe visual or auditory impairment that prevents understanding or performing the Box and Block Test

Individual participant data will not be shared because this is a single-case study and the data are potentially identifiable, making it difficult to fully protect the participant's privacy.
