Abstract
Objective
The aim of this study is to elaborate a valid and reliable Russian version of the ALSFRS-R.
Methods
Russian adaptation of the ALSFRS-R was applied twice in 50 ALS patients followed by the test–retest analysis with a 7-day interval between applications and internal consistency analysis.
Results
Test–retest analysis showed very strong correlation for all of the ALSFRS-R variables. The intra-class correlation coefficient was 0.83.
Conclusion
The elaborated Russian version of the ALSFRS-R has shown to be comparable with the original English version of the scale.
