OBJECTIVES: To assess the association of physical activity measures, derived with
an accelerometer and a self-reported questionnaire, with fear of movement in
patients with chronic nonspecific low back pain (LBP) and to investigate the
association between disability and fear of movement in this population. DESIGN:
Cross-sectional study. SETTING: Outpatient physical therapy university clinics.
PARTICIPANTS: Patients (N=119) presenting with nonspecific LBP of >3 months'
duration. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Physical activity
levels measured objectively with an accelerometer (ie, counts per minute, time
spent in moderate-to-vigorous and light physical activity per day, number of
steps per day, and number of 10-minute bouts of moderate-to-vigorous physical
activity per day) and subjectively with a self-reported questionnaire (Baecke
Physical Activity Questionnaire); fear of movement (Tampa Scale of
Kinesiophobia); pain (11-point numerical rating scale); disability (Roland Morris
Disability Questionnaire); and depression (Beck Depression Inventory). The
associations were examined with correlational, univariate, and multivariable
linear regression analyses. RESULTS: None of the objective physical activity
measures were associated with fear of movement.
The apparent association of
self-reported physical activity levels with fear of movement (correlational
analyses: r=-.18; P<.05; univariate regression analyses: beta=-.04; 95%
confidence interval [CI], -.07 to -.01; P=.04) was not confirmed in multivariable
analyses. Fear of movement was consistently associated with disability in both
correlational (r=.42; P<.01) and multivariable (beta=.21; 95% CI, .11-.31;
P<.001) analyses. CONCLUSIONS: Our data support one aspect of the fear-avoidance
model-that higher fear of movement is associated with more disability-but not the
aspect of the model linking fear of movement with inactivity.
