The Bobath approach, developed by K. and B. Bobath in the 1940s, focuses on treating cerebral palsy and adult hemiplegia by retraining normal movement patterns and normalizing abnormal tone. It emphasizes the avoidance of activities that increase abnormal muscle tone, incorporates the hemiplegic side into treatment, and aims to improve postural control and coordination. Key treatment techniques include reflex inhibiting patterns, handling methods, and sensory stimulation to facilitate normal motor control and functional independence.
