OBJECTIVE: To compare the test-retest reliabilities of the scores of the Balance
Computerized Adaptive Test (CAT) and the Biodex Balance System in patients with
stroke. DESIGN: A repeated-measures design (at a 1-wk interval) was used to
examine the test-retest reliabilities of the scores of the Balance CAT and the
Biodex Balance System. SETTING: One rehabilitation unit in a local hospital.
PARTICIPANTS: Patients (N=50) with stroke for more than 6 months and undergoing
outpatient rehabilitation completed the Balance CAT and the eyes open (EO)/closed
(EC) tests, but only 17 patients finished the Limit of Stability (LOS) test
because they were unable to reach all the targets. INTERVENTIONS: Not applicable.
MAIN OUTCOME MEASURES: The Balance CAT and 2 computerized tests of the Biodex
Balance System, namely the EO/EC test and the LOS, were used to evaluate balance
function. RESULTS: The test-retest reliabilities of the scores of the Balance CAT
(Pearson r=.92, minimal detectable change [MDC] percent=12.8%) was excellent.
Those of the EO/EC and LOS tests were poor to good (Pearson r=.56-.85,
MDC%=50.8%-126.9%). CONCLUSIONS: The test-retest reliabilities of the scores of
the Balance CAT were sufficient for assessing balance function in patients with
stroke. Moreover, the test-retest reliabilities of the scores of the Balance CAT,
one of the functional balance measures, were superior to those of the Biodex
Balance System, 1 type of computerized posturography instrument. Therefore, the
Balance CAT may be a more reliable measure for clinicians and researchers to use
in assessing the balance function of patients with stroke for more than 6 months.
