This study examined change in physical activity as a behavioral
correlate of short-term disability progression in persons with multiple sclerosis
over a 6-month period. DESIGN: Panel design. SUBJECTS: The sample included 292
persons with multiple sclerosis. METHODS: Participants wore an accelerometer for
7 days as a measure of physical activity and then provided demographics and
clinical information and completed the Patient Determined Disease Steps scale as
a measure of disability. After a 6-month period, participants provided
information about the occurrence of a relapse in the previous 6 months and again
wore an accelerometer for 7 days and completed the Patient Determined Disease
Steps scale. RESULTS: Panel analysis indicated associations between baseline
physical activity and disability (path coefficient= -0.41, p<0.001) and 6-month
change in physical activity and disability progression (path coefficient= -0.09,
p=0.025). CONCLUSION: Such findings provide preliminary support for a reduction
in physical activity as a behavioral correlate, but not necessarily cause, of
short-term disability progression in persons with multiple sclerosis.
