Fall Risk Assessment in COPD
Validity and Reliability of Balance Screening Tests for Fall Risk Assessment in COPD
Study Overview

Detailed Description
COPD is a leading cause of death, disability and hospitalization in Canada. In addition to the primary lung impairment, secondary effects of the disease are well established including impairments in muscle function, mobility and exercise capacity. Individuals with COPD also have marked deficits in balance and an increased risk of falls.
The updated American Thoracic Society/European Respiratory Society Statement on PR recommended expanding the scope of outcome assessment in COPD to include balance however no specific tests are suggested. An examination of brief balance measures feasible for fall risk screening has not been conducted. Such information will inform clinicians as to those most likely to benefit from targeted intervention. This study aims to determine the optimal balance measure for identifying patients with COPD who are high risk for falling.
The specific objectives of the study are to: 1) Investigate the construct validity (convergent and known-groups) and reliability (inter-rater and test-retest) of three short balance screening measures in people with COPD; 2) Investigate the predictive validity of the balance screening tests for falls; and 3) Identify cut-off scores for identifying fallers with COPD on the balance screening tool with the strongest psychometric properties.
One hundred and twenty individuals with COPD will be recruited from two sites. Upon enrolment, participants will undergo a physical assessment session measuring balance, functional lower body strength and exercise tolerance. Participants will also complete questionnaires of balance confidence, perceived physical function limitations, fall risk, dyspnea, global cognitive impairment and executive function. Participants will then be followed for 12 months to measure incidence of falls.
To assess inter-rater reliability of the primary measures, two raters will simultaneously administer the balance tests with a subset of the first 32 subjects to agree to participate in this study. This subset will also be asked to return for repeat testing two-three days after the baseline assessment to assess test-retest reliability.
