Bobath / neurodevelopmental treatment

After a stroke or in cerebral palsy, movement does not just become weak — it becomes wrong, locked into crude whole-limb patterns. Try to lift the arm and the whole limb may pull up in one stiff, stereotyped clench. The Bobath approach, developed in the mid-twentieth century by Berta and Karel Bobath, grew from the idea that these abnormal patterns should be discouraged and more normal movement coaxed out, rather than simply strengthening whatever the patient could do.

In practice the therapist uses hands-on guidance — careful handling, positioning, and key points of control such as the shoulder or pelvis — to inhibit the unwanted abnormal patterns and facilitate movement that looks and feels more normal, hoping the nervous system will adopt the better pattern. A therapist might, for instance, support and align a patient's trunk and shoulder so the arm can reach forward smoothly instead of yanking up into its usual spastic flexion. The original theory leaned heavily on old ideas that recovery recapitulates infant development and that tone could be normalized by handling.

Here honesty is essential. Bobath/NDT was enormously influential and is still widely taught and practised, and skilled handling clearly has value. But its original neurological theory has not held up well, and modern research has generally not found it superior to task-oriented, repetition-rich approaches — and on some measures it performs worse. The field has largely shifted toward training people in real, meaningful tasks with lots of practice. Bobath is best understood today as a foundational, still-evolving philosophy of handling rather than a proven recipe that beats the alternatives.
