Key result
The effort-limited treadmill walk test provided reproducible and valid measures of functional ability in postpolio syndrome, with intrarater reliability of 0.91 and test-retest reliability of 0.85.

Is an effort-limited treadmill walk test reliable and valid for measuring functional ability in subjects with postpolio syndrome?
Effect estimate: intrarater 0.91; test-retest 0.85
The effort-limited treadmill walk test is a reproducible and valid measure of functional ability in postpolio syndrome when a standardized protocol is used.
Finch et al. (2004) conducted an observational in Postpolio syndrome (n=15). Effort-limited treadmill walk test was evaluated on Reliability (generalizability correlation coefficients) and construct validity (intrarater 0.91; test-retest 0.85). The effort-limited treadmill walk test provided reproducible and valid measures of functional ability in postpolio syndrome, with intrarater reliability of 0.91 and test-retest reliability of 0.85.
