Study – Physical Activity Verses Short-Term Disability

Physical Activity Verses Short-Term Disability – Study

 

Association between change in physical activity and short-term disability progression in multiple sclerosis

Objective:

 

This study examined change in physical activity as a behavioural 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 behavioural correlate, but not necessarily cause, of short-term disability progression in persons with multiple sclerosis.
