We use our own unique systematic assessment program called PERPOS (Pate Environmentally Relevant Program Outcome System) as the basis for much of our research. This approach accurately and precisely measures an individual’s distraction and structure tolerance and culminates in a plan that helps patients prepare for the next step in their lives.

PERPOS is a measurement tool that focuses on the complex interactions of the environment and ability.  It is comprised of three items: two primary environmental ratings (the amount of structure needed and distraction tolerated) and one rating of overall functioning/deficit.  Lower PERPOS scores represent a greater degree of impairment, while higher scores represent a lesser degree of impairment.

PERPOS scores are determined during biweekly treatment team meetings, which include neuropsychologists, physical therapists, occupational therapists, speech language pathologists, case managers and other members of the clinical team.

Below are images showcasing the various structures and distraction levels of PERPOS.

High-level Structure, Low-level Distraction – Therapist directed activity provides patient with limited choices in a quiet environment with only the therapist and patient.
Mid-level Structure, Mid-level Distraction – Therapist aided activity in an environment with more people around and more to see.
Low-level Structure, High-level Distraction – Replication of real life situations such as grocery shopping that provides a highly distractive environment in which the patient may be structuring him/herself with little to no input from the therapist.

How We Can Use PERPOS Information

The chart shown at the left is a backdrop that an individual patient’s data can be superimposed upon.  This can be used for:

  • Forecasting effective length of stay
  • Therapists’ treatment planning
  • Justification of progress to payor
  • Patient insight development
  • Progress monitoring (data bi-weekly)
