In rehab decisions, swelling imaging such as ultrasound is used to:

• A. Guide progression by assessing tissue damage extent and healing
• B. Determine the need for surgery
• C. Replace clinical assessment entirely
• D. Assess cardiovascular endurance

Answer: (A)

Swelling imaging like ultrasound is used to guide rehab progression by showing how much tissue damage exists and how healing is progressing. It lets clinicians visualize soft tissues, edema, fiber integrity, tissue thickness, and changes in blood flow, so they can judge whether the healing trajectory supports moving to higher loads and more functional activities. If the scan shows reduced swelling and more organized fiber structure, it supports advancing rehabilitation; if edema persists or fibers remain disrupted, progression is slowed to protect the tissue. This imaging complements clinical assessment—pain, range of motion, strength, and functional tests remain essential. It isn’t used to decide on surgery on its own, nor does it replace clinical evaluation or measure cardiovascular endurance.
