It is harder to differentiate them on the basis of their theoretical model, as few describe one.
Models that do appear tend to describe the relationships between cognitions and performance but do not indicate what the technology for changing the relationship would look like .
The modeling process and the rehabilitation approaches have been influenced by approaches to the rehabilitation of traumatic brain injury.
For instance , the Spaulding et al(2003)model of cognitive recovery is relatively bottom-up model with basic cognitive functions being the prime target.
This is akin to some of the models of brain plasticity.
This is one of the few models that could drive technology for rehabilitation.
