What is the purpose of the ICU Mobility Scale (IMS)?

• A. It predicts length of stay.
• B. It provides a standardized score (0–10) reflecting mobility level and guides progression and safety decisions.
• C. It measures respiratory rate.
• D. It grades pain severity.

Answer: (B)

The main idea is that the ICU Mobility Scale is used to quantify how mobile a patient is in the ICU so you can progress activity safely. It gives a standardized score from 0 to 10 that reflects the current mobility level, from minimal or passive movement to independent activity. This score helps the care team decide when it’s appropriate to advance to more challenging mobilization tasks, set realistic rehab goals, and monitor safety—such as tolerance to activity and need for assistive support. It isn’t designed to predict how long the patient will stay in the ICU, measure respiratory rate, or grade pain; those aspects are separate. Instead, mobility level and safe progression are the focus, and the IMS provides a clear, communicable way to track and guide rehabilitation decisions.
