Once the test is performed with a client, the results will be shown in a chart.
The HFS is easily scored and yields a single "Rating of Perceived Capacity" which ranges from
zero to 248. Three "internal validity check" drawings are included which are similar to drawings
presented earlier.
Normative values for both healthy and disabled males and females are provided in the HFS
examiner's manual. Additionally, the Rating of Perceived Capacity score can be cross-referenced
to the U.S. Department of Labor's Physical Demand Characteristic of Work system.
The normative values allow the evaluator to compare functional test results, the HFS score, and
the target job's demands, providing a crucial three-way cross-validation of findings.
EPIC Spinal Function Sort
The purpose of the 50-item Spinal Function Sort (SFS) is to quantify the disabled person's
perception of their ability to perform work tasks that involve the spine. This can be useful to
provide a baseline measure of the client's perception of their functionality prior to the onset of
intervention.
The client is instructed to "Look at each drawing and read the description. On a separate answer
sheet, indicate your current level of ability to perform the task."
