Neurodevelopmental treatment(NDT) is a widely used technique by physical and occupational therapists in the treatment of neuromuscular disorders. Childeren with cerebral palsy are frequently referred for physical and occupational therapy, yet the effectiveness of treatment has not been well-documented. More than 40 years ago, the Bobath introduced a treatment concept for individuals with central nervous system impairment. A theoretical framework for the approach was based on the common belief in the 1940s that the nervous system functions in a hierarchy. Clinical aspects of the NDT approach have grown and changed during the past 40 years. This article details the original NDT concepts and looks at the concept with regard to newer theoretical frameworks of nervous system.
