The concept of a recovery "plateau" is widely misunderstood — both by patients and, increasingly, researchers are finding, by the healthcare system that communicates it. A plateau is not a biological ceiling. It is not evidence that the brain has exhausted its capacity to change. In the vast majority of cases, a plateau is simply what happens when repetition stops.
When OT sessions end, daily repetition drops dramatically. The neural signals that were beginning to rebuild lose their stimulus. Progress slows, then stops. The brain, deprived of the consistent input it needs, simply maintains the status quo. This is not permanence. This is physics.
The research on chronic stroke recovery — patients who are 6, 12, even 24 months post-stroke — consistently shows that meaningful functional improvement remains achievable long after the conventional recovery window has closed, provided that sufficient, consistent, task-specific repetition is reintroduced.
