The WorkAbility Rate of
Manipulation Test (WRMT), an adaptation of the Minnesota Manual Dexterity Test
(MMDT), contains a revised board and protocols to improve its utility for therapy
or fitness assessment. PURPOSE OF THE STUDY: To describe the development and
preliminary psychometric properties of WRMT.
METHODS: Sixty-six healthy
participants completed MMDT and WRMT in a random order followed by a user
experience survey. We compared tests using repeated-measures analysis of
variance, test-retest reliability, and examined agreement between tests. RESULTS:
Despite the similarities of these 2 instruments, the different administration
protocols resulted in statistically different score distributions (P < .001).
Results supported good test-retest reliability of WRMT (placing test ICC =
0.88-0.90 and turning test ICC = 0.68-0.82). The WRMT correlated moderately with
MMDT (r = 0.81 in placing test and r = 0.44-0.57 in turning test). Bland-Altman
plot showed that the differences in completion time were 3.8 seconds between
placing tests and 19.6 (both hands), 0.3 (right hand), and 3.9 (left hand)
seconds between turning tests. Overall, participants felt that the instruction of
WRMT was easier to follow (44%) and preferred its setup, color, and depth of the
test board (49%). Time required to complete 1 panel of 20 disks correlated highly
with the time needed to finish a complete trial of 60 disks in both MMDT (r =
0.91-0.97) and WRMT (r = 0.88-0.95). CONCLUSIONS: Caution is warranted in
comparing scores from these 2 test variants. LEVEL OF EVIDENCE: 3b.
