Abstract
Objective
To examine the intrarater and interrater reliability of a quick balance measure, the
Hierarchical Balance Short Forms (HBSF), in outpatients with stroke receiving rehabilitation.
Design
A repeated-assessments design (1wk apart) was used to examine the intrarater and interrater
reliability of the HBSF. The HBSF was administered by a single rater in the intrarater
reliability study and by 2 raters in the interrater reliability study. The raters
had sufficient working experience in stroke rehabilitation.
Setting
Seven teaching hospitals.
Participants
Two independent groups of outpatients (N=106; each group, n=53) with stroke in chronic
stages and in stable medical condition were recruited.
Interventions
Not applicable.
Main Outcome Measure
HBSF.
Results
For the intrarater reliability study, the values of the intraclass correlation coefficient
(ICC), minimal detectable change (MDC), and percentage of minimal detectable change
(MDC%) were .95, 1.02, and 16.3%, respectively, for the HBSF. The 95% limits of agreement
(LOA) of the HBSF ranged from −.69 to 1.19. For the interrater reliability study,
the values of the ICC, MDC, and MDC% were .91, 1.22, and 18.3%, respectively, for
the HBSF. The 95% LOA of the HBSF ranged from −1.01 to 1.35.
Conclusions
Our results suggest that the HBSF has satisfactory intrarater and interrater reliability
for assessing balance function in outpatients with stroke. The MDC values of the HBSF
are useful for both researchers and clinicians to determine whether the change in
balance function of an individual patient is real when administered by an individual
rater or by different raters.
