This study determined whether kinesiophobia levels were different
among older adults with chronic low back pain (LBP) and varying body mass index
and whether kinesiophobia predicted perceived disability or walking endurance.
DESIGN: This study was a secondary analysis from a larger interventional study.
Older adults with obesity with LBP (N = 55; 60-85 yrs) were participants in this
study. Data were stratified on the basis of body mass index: overweight (25-29.9
kg/m), obese (30-34.9 kg/m), and severely obese (35 kg/m). The participants
completed a battery of surveys (the modified Tampa Scale of Kinesiophobia
[TSK-11], the Fear-Avoidance Beliefs Questionnaire, the Pain Catastrophizing
Scale, and the perceived disability measures of the Oswestry Disability Index and
the Roland Morris Disability Questionnaire). Walking endurance time was captured
using a symptom-limited graded walking treadmill test. The peak LBP ratings were
captured during the walk test. RESULTS: Walking endurance times did not differ by
body mass index group, but the peak LBP ratings were higher in the moderately and
severely obese groups compared with the overweight group (3.0 and 3.1 vs. 2.1
points; P < 0.05). There was no difference in the kinesiophobia scores (the
TSK-11, the Pain Catastrophizing Scale, and the Fear-Avoidance Beliefs
Questionnaire work and activity subscores) or the perceived disability scores
(the Oswestry Disability Index and the Roland Morris Disability Questionnaire).
However, adjusted regression analyses revealed that the TSK-11 scores contributed
10%-21% of the variance of the models pain with walking and perceived disability
caused by back pain. Kinesiophobia was not a significant contributor to the
variance of the regression model for walking endurance. CONCLUSIONS: In the older
population with obesity with LBP, the TSK-11 might be a quick and simple measure
to identify patients at risk for poor self-perception of functional ability. The
TSK and the Oswestry Disability Index may be quick useful measures to assess
initial perceptions before rehabilitation. Kinesiophobia may be a good
therapeutic target to address to help affected older adults with obesity fully
engage in therapies for LBP.
