Validation and reproducibility of the Glittre activities of the daily living test for evaluation of functional capacity after a stroke

ABSTRACT

To investigate the Glittre Daily Living Activity (ADL) test’s validity and reproducibility for assessing functional capacity in stroke patients.

Methods

Thirty patients with hemiparesis stemming from a stroke and 20 healthy peers were evaluated. Reproducibility was determined using the intraclass correlation coefficient (ICC), standard measurement error (SME), minimum detectable change (MDC), and Bland-Altman analysis. For construct validity, the Glittre ADL test was correlated with the Six-Minute Walk Test (6MWT), Timed Up and Go Test (TUG), and Functional Independence Measure (FIM), and analyzed based on convergent validity and the comparison of known groups (stroke survivors and healthy peers).

Results

Intra- and inter-observer reliability were excellent (ICC_3,1 = 0.98; 0.96, respectively). Intra-observer SME ranged from 0.27 to 0.31 minutes and inter-observer SME was 0.45 minutes. Intra-observer MDC ranged from 1.44 to 1.54 minutes and inter-observer MDC was 1.86 minutes. Strong statistically significant correlations were found between time on the Glittre ADL test and time on the 6MWT (rh = −0.91; p < .001) and TUG test (rh = 0.82; p < .001), whereas a moderate correlation was found with the FIM (rh = −0.47; p < .008).

Conclusions

The Glittre ADL test is valid for assessing functional capacity in stroke patients. It demonstrated good convergent and construct validity and excellent intra- and inter-observer reproducibility.
