OBJECTIVES: To examine the convergent validity, sensitivity to change, floor and
ceiling effects of the Community Balance and Mobility Scale (CB&M) in
community-dwelling stroke survivors. The secondary objective was to determine the
correlations between the CB&M and lower-limb motor recovery and strength.
DESIGN: Validity study. SETTING: Two university-based research centers. PARTICIPANTS:
Community-dwelling persons after stroke (N=44; 24 men, 20 women; mean age,
62.6+/-12.6y). Baseline measures were taken 3 months after the onset of stroke
(98.6+/-52.6d); participants were reassessed 8 months poststroke (246.8+/-57.2d).
INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: CB&M, Berg Balance Scale
(BBS), Timed Up & Go (TUG), Chedoke McMaster Stroke Assessment (CMSA) Impairment
Inventory for leg and foot, concentric bilateral isokinetic strength of the
lower-limb flexor and extensor muscle groups using a dynamometer. The magnitude
of the associations and the standardized response means (SRMs) among the CB&M,
BBS, and TUG were used to examine the convergent validity and sensitivity to
change, respectively. RESULTS: Moderate to high convergent validities (rho=.70 to
.83, P<.001) were observed among the CB&M, BBS, and TUG. The CB&M was moderately
correlated with the CMSA leg and foot scores (rho=.61 and .63, respectively,
P<.001) and the paretic limb strength (rho=.67, P<.001). The CB&M demonstrated
the greatest ability to detect change between the baseline and follow-up
assessments (SRM=.83). CONCLUSIONS: The CB&M is valid and sensitive to change in
assessing functional balance and mobility in ambulatory stroke survivors with
moderate to mild neurologic impairments.
