Test–retest reliability of the StepWatch Activity Monitor outputs in individuals with chronic stroke

Mudge, S., Stott, N. S.

The objective of this test was to examine the test—retest reliability of the StepWatch Activity Monitor outputs over two periods in participants with stroke.  Forty participants more than six months post stroke were included and total step count, number of steps at high medium and low stepping rates, sustained activity indices, peak activity index were measured.

Total step count, highest step rate in 1 minute, highest step rate in 5 minutes and peak activity index have good test—retest reliability over a three-day monitoring period, with lower reliability shown by the other StepWatch outputs. In general, monitoring over one or two days is less reliable.
