Abstract

Background: The Arm Function in Multiple Sclerosis Questionnaire (AMSQ) is the first validated disease specific patient-reported outcome measure (PROM) designed to assess upper extremity function in patients with multiple sclerosis (MS). Objective: To determine correlations between the AMSQ and established physician- and performance based outcome measures. Methods: In a cross-sectional cohort of 533 patients correlations between the AMSQ and the Expanded Disability Status Scale (EDSS), its functional systems, the 9-Hole Peg Test (9-HPT) and the Timed-25 Foot Walk (T25FW) were determined. Subgroup analyses were performed as well. Also, correlations were determined in 110 of 533 patients with available longitudinal data. Results: Strongest correlations were found in the cross-sectional cohort between the AMSQ and the EDSS (β 0.60, p<.001), the 9-HPT dominant hand (β 0.52, p<.001) and 9-HPT non-dominant hand (β 0.46, p<.001), the Pyramidal (β 0.57 p<.001) and the Cerebellar functional system (β 0.54, p<.001) of the EDSS. Conclusion: The moderate correlations between the AMSQ and several established physician- and performance based outcome measures underline that the AMSQ, an easily at long-distance administrable PROM, could be considered as a reliable outcome measure for the monitoring of MS in daily practice. Additional research is needed to support these findings.
