Rolland Morris Disability Questionnaire
Change in psychophysical capacity, calculated as the ratio between
physical capacity and perceived effort, may be a determinant of change in
perceived disability. The aim of this study was to identify determinants for
change in perceived disability, as measured with the Roland Morris Disability
Questionnaire (RMDQ), in patients with non-specific chronic low back pain after
rehabilitation. METHODS: Data were gathered for 84 outpatients. Psychophysical
capacity (psychophysical static leg lift, psychophysical static trunk lift, and
psychophysical dynamic lifting capacity), physical lifting capacity, perceived
lifting effort, aerobic capacity and RMDQ were assessed. Associations between
change in RMDQ and potential determinants were calculated. Variables associated
with change in RMDQ were entered in a multivariate linear regression analysis
(backward). RESULTS: Change in psychophysical static trunk lift (r = -0.51),
psychophysical dynamic lifting capacity (r = -0.53) and psycho-physical static
leg lift capacity (r = -0.23) were significantly associated with change in RMDQ.
The RMDQ score at baseline (beta = -0.438), change in psychophysical dynamic
lifting capacity (beta = -0.109), psychophysical static trunk lift capacity (beta
= -0.038), psychophysical static leg lift capacity (beta = -0.012) and static leg
lift capacity (beta = 0.007) all contributed significantly to the regression
model (r2 = 52%). CONCLUSION: Improvements in psychophysical lifting capacity are
determinants for a reduction in perceived disability.
