OBJECTIVES: To systematically review the instruments used to assess postural
control and fear of falling in people with chronic obstructive pulmonary disease
(COPD), and to synthesize and evaluate their breadth of content and measurement
properties. DATA SOURCES: MEDLINE, EMBASE, Web of Science, CINAHL, CENTRAL,
PsycINFO, PEDro, and OTSeeker databases searched in September 2012. STUDY
SELECTION: Two independent reviewers performed the selection of articles, the ICF
linking process and quality assessment. Only quantitative studies were included,
irrespective of language or publication date. DATA EXTRACTION: This systematic
review comprised two phases. Phase 1 aimed to identify the commonly used
instruments to assess postural control and fear of falling in the COPD
literature. The breadth of content of each instrument was examined based on the
International Classification of Functioning, Disability and Health (ICF). In
phase 2, a measurement property search filter was adopted and used in four
electronic databases to retrieve properties reported in the COPD population. The
COSMIN checklist was used to assess the methodological quality of each
measurement property reported. DATA SYNTHESIS: Seventeen out of 401 publications
were eligible in phase 1. Seventeen instruments were identified including 15 for
postural control and 2 for fear of falling assessment. The Berg Balance Scale,
the Short Physical Performance Battery, and the Activities-specific Balance
Confidence (ABC) scale were the most frequently used instruments to assess
postural control and fear of falling respectively. The ICF categories covered
varied considerably among instruments. The Balance Evaluation Systems test and
ABC presented the greatest breadth of content. Measurement properties reported
included criterion predictive validity (4 instruments), construct validity (11
instruments) and responsiveness (1 instrument), with inconsistent findings based
on 'fair' and 'poor' quality studies. CONCLUSIONS: Different instruments with
heterogeneous content have been used to assess postural control and fear of
falling outcomes. Standardized assessment methods and best evidence on
measurement properties is required in the COPD literature.
