Which statement best describes the use of normative values in PT assessment?

• A. Provide reference points for comparison
• B. Compare patient performance to normative data
• C. Determine legal compliance
• D. Diagnose disease

Answer: (C)

Normative values come from a reference group and establish what is typical for a given population. In PT assessment, the main use is to compare a patient’s performance to those normative data. This comparison shows whether their function falls within normal limits, is below expected, or exceeds typical performance. That understanding helps interpret test results, set realistic goals, and track progress over time. It’s not about legal compliance, and a single normative comparison by itself doesn’t diagnose disease—diagnosis relies on a broader clinical picture and additional information. So, the essential idea is to compare patient performance to normative data to judge how it stacks up against typical expectations.
