Background/Objectives: Pediatric cerebral palsy (CP) is a neurological disorder that affects motor skills, posture, and muscle coordination, impacting children’s daily functioning and quality of life. Treatment approaches in occupational therapy aim to enhance motor function and functional independence through a variety of rehabilitative techniques. Recently, new technologies—such as virtual reality, robotics, and assistive devices—have emerged as promising tools in occupational therapy to complement traditional interventions and potentially enhance motor and sensory outcomes in children with CP. This systematic review aims to analyze the effectiveness of these innovative technological interventions in the rehabilitation of children with CP. Methods: A systematic review was conducted and different scales were used to assess the risk of bias and methodological quality. The degree of evidence and level of recommendation were established according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). The review adhered to PRISMA guidelines, with a comprehensive literature search performed across multiple databases, including Cochrane, Web of Science, and PubMed. This systematic review has been registered in the PROSPERO database with the registration number CRD42025630162. Results: The reviewed studies indicate that technologies such as functional electrical stimulation, robotic assistance, and adaptive devices have shown improvements in mobility, motor control, posture, strength, and autonomy in children with CP. Similarly, virtual environments support the correction of facial dysfunctions and enhance social interaction through video games and social networks. While these tools hold significant potential for rehabilitation, further adjustments are needed to achieve more consistent results. Conclusions: Emerging technologies appear to be effective tools in occupational therapy for pediatric CP, with positive impacts on motor skills and functional capabilities. Nevertheless, further studies with larger sample sizes and rigorous methodological designs are necessary to confirm these findings and establish more robust evidence on their long-term efficacy.
