Lesson 1Interpretation and clinical reasoning: integrating findings to plan prehab, immediate priorities, and referralsThis section explains how to synthesize subjective and objective findings into a clear problem list, set short‑term priorities, decide on prehabilitation focus, and determine when to refer urgently to orthopedic or medical specialists.
