Dynamic Systems Theory Framework in Physiotherapy Management of Children with Joubert Syndrome: A Case Study

Joubert Syndrome (JS) is a rare neurodevelopmental disorder characterized by cerebellar and brainstem malformations, resulting in hypotonia, motor delays, and poor coordination. Physiotherapy plays a key role in improving functional outcomes, yet standardized management strategies remain limited. This case study highlights the application of the Dynamic Systems Theory (DST) framework in physiotherapy management of a child with JS, emphasizing functional diagnosis and patient-centered care. A 5-year-old boy with JS presented with motor delays, hypotonia, and impaired postural control. Using the DST approach, a tailored physiotherapy program was designed addressing neuromuscular, sensory, cognitive, and environmental subsystems. Interventions included sit-to-stand training, gait activities, sensory integration, coordination tasks, and respiratory exercises. Outcome measures used were the Gross Motor Function Measure (GMFM) and Pediatric Berg Balance Scale and WEEFIM. Over five weeks, the child showed significant improvement in balance, coordination, and functional independence. GMFM and balance scores improved markedly. Active family involvement and a structured environment enhanced engagement and therapy outcomes. The DST framework proved effective in managing the complex motor impairments of JS by promoting adaptability and functional gains. Functional diagnosis enabled targeted, task-specific interventions, resulting in improved quality of life and independence. This approach holds promise for broader application in rare neurodevelopmental conditions. Key words: Joubert Syndrome, Dynamic Systems Theory, Functional Diagnosis, Paediatric Physiotherapy.
