Walking speed is a highly valid test , both at habitual and maximum speed .
Both habitual and maximum walking speeds are valid instruments , and they predict death , hospitalization/institutionalization , and decline in mobility
The number of available walking tests has increased dramatically over the past decades .
Therefore , it is highly important to help clinicians choose the most appropriate walking test for a specific setting .
This systematic review aim ed to critically evaluate the reliability , validity , and responsiveness of clinical walking speed in a broad population of elderly persons living in the community , sheltered housing , or institutions .
A comparison of two time intervals for test-retest reliability of health status instruments.
Studies of test-retest reliability for health-related quality of life instruments have used varying intervals between test administrations . There is no evidence available to aid in the selection of the time interval between question naire administrations for a study of test-retest reliability for health status instruments . We compared the test-retest reliability at 2 days and 2 weeks for four knee-rating scales and the eight domains of the SF-36 . Seventy patients with disorders of the knee who were in a stable state were r and omly allocated to repeat the question naires at either 2 days or 2 weeks . There were no statistically significant differences in the test-retest reliability ( intraclass correlation coefficient and limits of agreement statistics ) for the two time intervals
