On the IMS, what does a score of 0 represent?

• A. Walking independently without gait aid
• B. Sitting in a chair
• C. Lying in bed with no active movement
• D. Standing at edge of bed

Answer: (C)

IMS measures how much active movement a person can perform in a given position or task. A score of zero means there is no active movement at all in that domain—the person is bed-bound and cannot initiate movement. This is the lowest level of impairment on the scale. Higher scores reflect increasing ability: standing at the edge of the bed requires some weight-bearing and motor control; sitting in a chair requires maintaining an upright posture with some active movement; walking independently without a gait aid requires full locomotor function. So, zero corresponds to lying in bed with no active movement.
