Manual Ability Measure (MAM-36)

The MAM-36 asks how hard everyday hand tasks feel — cutting meat on a plate, taking things out of a wallet, opening a childproof medicine bottle. Not how fast a person does them or how the movement looks, but how much difficulty they experience doing them.

Thirty-six tasks are rated on a four-point scale: easy, a little hard, very hard, or cannot do, with a separate option for tasks the person almost never does. Ratings cover the task however the person accomplishes it, regardless of which hand is used and without assistive devices. Raw ratings are converted through a Rasch-derived table into an interval-level measure, which is what allows change between intake and discharge to be compared meaningfully.
