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.

Keywords: ASLFRS-R; Reliability; Russian version; Validity.
