if you search pub med for Alina Fong under author you will find her three papers. Dr. Allen is the other neuropsych that has published many papers using fmri. I think these papers are free for viewing.

on cognitive's website you can request their latest paper under research/technical reports:
developing the standard of care for post concussion treatment: etc.

as you said, it mentions little about what the treatments are, but I can tell you generally. They consist of very specific cognitive, vestibular/occular and visual exercises that are known to target certain areas in the brain. They employ these exercises aggressively and alternating with periods of rest to 're-awaken' the areas of the brain that are poorly activating as shown on fmri. These exercises are a result of about a decades worth of trial and error research. They also incorporate neuromuscular therapy and psych therapy when needed.

Their treatment clinic used to take several months, but as they got better at targeting their desired areas, they found that they needed less time to achieve maximum benefit from the techniques, till they arrived at their current week long plan.
