The Mayo-Portland Adaptability Inventory (MPAI-4) is the industry standard in measuring functional outcomes for post-acute brain injury rehabilitation programs. The tool measures outcomes based upon 29 functional measures in three areas: ability, adjustment and participation. This data represents 4,000 persons sample.
“With the gains being held for most individuals at 12 months post discharge from a residential rehabilitation program, the return on investment is evident even if the person does not receive additional therapy following residential care. The return is also evident as costs reduce with each subsequent level of care yet gains are maintained, or continue with improvement of functional skills (Lewis & Horn, 2024).
Key Findings
- On average, individuals demonstrated an increase in functional independence across all 29 items of the MPAI-4.
- On average, individuals improved one severity level on each of the three MPAI-4 subscales.

- National Reference Sample
Average Age = 46.9, Average Length of Stay = 152 days. Outcomes for all persons treated in active rehabilitation.
On average, our participants demonstrated an increase in functional independence across all 29 items of the MPAI-4.
