Italian Validation of the 12-Item Multiple Sclerosis Walking Scale

الملخص EN

Objective.

Gait impairment is commonly in people with multiple sclerosis (MS).

The 12-item MS walking scale (MSWS-12) assesses patients’ measurement of walking quality.

The aim of this study was to cross-culturally adapt and validate the MSWS-12 for the Italian population with MS.

Methods.

Six MS out-patient clinics across Italy enrolled subjects between June 2013 and December 2013.

Construct validity of MSWS-12 was determined by examining correlations with the Italian version of the EDSS, the timed 25-foot walk (T25FW), and the Fatigue Severity Scale (FSS).

Results.

321 MS subjects were enrolled.

Mean age was 47.55 years and mean disease duration was 13.8 years.

Mean EDSS score was 4.46.

185 subjects had a relapsing-remitting course, 92 were secondary progressive, 43 were primary progressive, and 1 had a clinically isolated syndrome.

The mean total score of the MSWS-12 was 49.6 (SD: 31) with values ranging between 0 and 100.

Correlations between the MSWS-12 with age, disease duration, and disease course were found but not with gender.

Values of the MSWS-12/IT were significantly related to EDSS (0.71), to the T25FW (0.65), and to the FSS (0.51).

Conclusion.

MSWS-12/IT has been adapted and validated, it is a reliable and reproducible scale for Italian patients with MS.
