The development and preliminary validation of the Taiwanese manual ability measure for burns

Objective: To develop and validate the Taiwanese Manual Ability Measure for Burns (T-MAM for Burns), a task-oriented functional evaluation tool to assess self-reported manual ability in burn patients. Design: A longitudinal study. Participants: A sample of 45 burn patients from burn rehabilitation centers with varying degrees of hand involvement. Methods: The preliminary testing version was formed by adding burn specific items to the Taiwanese version of the Manual Ability Measure. A field test was then conducted for item reduction and psychometric properties testing. Results: Out of 55 initial items, 20 were selected into the final version of the T-MAM for Burns. Psychometric analyses indicated that it was reliable (test-retest ICC =.99), with adequate concurrent validity with various other hand function tests (r = -.79 with the short form Disabilities of the Arm, Shoulder, and Hand, or, the QuickDASH) and discriminative validity (significant difference (t = 2.99, P =.005) between groups with unilateral vs. bilateral hand burns), and responsive (ES =.24 and.44 at one- and 3-month evaluations). Conclusion: This study shows that the T-MAM for Burns has great potential to be a functional outcome measure for burn rehabilitation. Additional research with a larger sample should be conducted to further confirm its validity and reliability. ? 2013 Elsevier Ltd and ISBI. All rights reserved.
