Phase 1 may last up to how many days?

• A. 2 days
• B. 4 days
• C. 7 days
• D. 14 days

Answer: (B)

Phase 1 is the initial, acute stage after injury when inflammation and tissue protection are the focus. The body's inflammatory response dominates, causing swelling, pain, and guarded movement. This phase typically lasts up to about four days, though it can vary with the individual and injury. Four days is the practical upper limit used in many rehab models because it aligns with the peak acute inflammatory window before transitioning toward subacute healing. A shorter window, like two days, wouldn’t capture the full acute response; a duration around seven or fourteen days would indicate progression into subacute or proliferative phases rather than Phase 1. In this stage, management centers on protecting the area, reducing swelling, modulating pain, and initiating gentle, tolerance-based movements rather than aggressive loading.
