Below is Christine Chen's occupation-based, 20-question MAM hand assessment, as described in the cover story of the July 18, 2011, ADVANCE for Occupational Therapy Practitioners print edition. The author strongly urges clinicians not to just add up the ratings but use a Rasch-derived MAM measure which can be found in a conversion table (from raw sum scores to the MAM measures). The MAM measure is an interval measure calibrated by the Rasch computer software; it ranges from 0 (no ability) to 100 (high ability). The conversion table for the MAM-20 can be obtained from the author at ccc2114@columbia.edu.
