What is key to performing passive ROM for the knee safely?

• A. Move the joint slowly within a pain-free range, support the limb, do not force beyond limits
• B. Move the joint rapidly within a pain-free range
• C. Force beyond limits if there is resistance
• D. Only move the joint if resident requests it

Answer: (A)

Safe knee passive range of motion focuses on moving the joint slowly within a pain-free range, while supporting the limb and never forcing beyond what the joint can tolerate. Moving slowly helps tissues stretch gradually, reducing the risk of injury and guarding, and proper support keeps the knee aligned and protects surrounding structures. Forcing through resistance or moving rapidly increases the chance of tissue damage, ligament strain, or irritation to the joint. Passive ROM is performed by the caregiver as part of the recovery plan, not only when the resident asks for it, to maintain mobility and circulation while respecting limits.
