OBJECTIVE: To review the literature for the criterion validity of pedometers for
use in child and adult populations with physical disabilities. DATA SOURCES:
Academic Search Premier, ERIC, SPORTDiscus, MEDLINE, AMED, Scopus, CINAHL, Web of
Science, and EMBASE databases, searched from inception to September 7, 2011.
STUDY SELECTION: Studies were included if they were peer-reviewed articles,
included populations with physical disabilities, and reported primary data for
pedometer validity in comparison with direct observation. A consensus approach
was used to apply the inclusion and exclusion criteria. Of the 163 articles
identified in the database searches (excluding duplicates), 7 studies met the
inclusion criteria. DATA EXTRACTION: The quality of the studies was assessed
independently by 2 reviewers, using a purpose-designed appraisal tool, with a
consensus approach used to settle disagreement. A single reviewer extracted data
relating to sample size, participant characteristics, pedometer model, main
variables tested, duration of tests, and method of direct observation. DATA
SYNTHESIS: The methodologic quality of the studies was generally high; however,
there was a wide variation of population and methodology between studies. The
correlation between pedometer step counts and directly observed step counts was
moderate to excellent (intraclass correlation coefficient, .52-.87), and percent
errors ranged from 0.5% to 24.7%. Secondary variables reported included the
effect of speed of movement, pedometer placement, comparison of pedometer
makes/models, and test-retest reliability. CONCLUSIONS: Available evidence
suggests that pedometers are valid for use in clinical and research settings in
people with physical disabilities. Further research examining the validity of
pedometers in less heterogeneous populations of people with disabilities is
warranted to determine validity for specific disability populations and to
determine optimal pedometer placement.
