Which of the following is an example of a Patient Reported Outcome Measure?

A Patient Reported Outcome Measure (PROM) refers to the types of evaluations that gather information directly from the patient about their health condition, treatment effects, and quality of life, capturing their personal perceptions and experiences. Functional scales such as the Lower Extremity Functional Scale (LEFS) or the Shoulder Pain and Disability Index (SPADI) specifically ask patients to report on their functional abilities and the impact of their condition on their daily life. This self-reported information provides valuable insights that are crucial for understanding the patient's perspective on their health status and treatment efficacy.

In contrast, the other options involve measurements that are typically clinician-administered and do not derive directly from the patient's own reports. Range of motion (ROM) scales, strength measurements, and endurance tests are all objective measures used to assess clinical performance that may help to evaluate treatment effectiveness, but they do not capture the patient's subjective experience or self-reported outcomes, which is the essence of PROMs.
