The adult myopathy assessment tool (AMAT).

^†Denotes AMAT endurance subscale items.

General instructions: all AMAT items should be performed in order 1 through 13 with at least one-minute rest period after each item. Rest periods exceeding one minute are dictated by the transition time required to set up proceeding AMAT tasks. Test ending criteria should be provided prior to each task attempt. Standby assistance is required for all items requiring upright mobility. Duration for all timed tasks should be recorded. Required items: stopwatch, examination table, goniometer or inclinometer, and stairs with a handrail.

Scoring: Each AMAT item is scored immediately after the task attempt is completed. The AMAT functional subscale (range = 0–21), AMAT endurance subscale (range = 0–24), and AMAT total score (range = 0–45) are calculated after test administration.

Interpretation: AMAT functional level (categorical ranks are based on the AMAT total score)

1-low 0–24

2-moderate 25–34

3-high 35–45

PROM: passive range of motion.
