OBJECTIVES: To evaluate the characteristics and available evidence on the
measurement properties of the gait speed (GS) test, timed Up and Go test (TUG),
sit-to-stand (STS) test, and step test; to investigate their relation with
clinical outcomes in chronic obstructive pulmonary disease (COPD); and to provide
recommendations for clinical practice and future research. DATA SOURCES: Studies
were systematically identified from a literature search using PubMed, PEDro, CINAHL, and Cochrane Library databases and the reference lists of the included
articles. STUDY SELECTION: Studies including >/=1 of these 4 lower limb
functional tests (GS test, TUG, STS test, and step test) as an outcome in
patients with COPD were selected. No limits were applied for language and study
design. DATA EXTRACTION: Two researchers independently performed data extraction
and, by using the COnsensus-based standards for the Selection of health status
measurement INstruments, assessed the quality of those studies that described
measurement properties.
DATA SYNTHESIS: Forty-two articles met the selection
criteria. GS test, STS test, and step test are valid, reproducible, and
responsive tests, especially the 4-meter GS, 5-repetition STS test, and 6-minute
step test (6MST). The TUG is reliable; however, studies on other measurement
properties of this test are lacking. Outcomes of these tests are correlated with
mortality, physical activity in daily life, exercise capacity, dyspnea, and
quality of life. CONCLUSIONS: Simple and functional lower limb tests provide
information about important clinical outcomes in patients with COPD. The 4-meter
GS, 5-repetition STS test, and 6MST are tests with well-established psychometric
properties, whereas the properties of the TUG need to be studied further.
