“…Since then, the MSWS-12 has been translated and validated in a variety of countries and languages. [8][9][10] In the last decade, item response theory (IRT) models have been extensively applied to develop new instruments; evaluate the quality of existing measurement instruments (developed using classical test theory (CTT)), or refine existing scales by optimally shortening the scale; and evaluate the performance of the reduced scale. 11 IRT models include a trait level for an individual, represented by θ.…”

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.

“…7,8 The 12-item Multiple Sclerosis Walking Scale (MSWS-12) is a commonly adopted patient-reported outcome measure used to assess the extent to which MS impacts the walking ability, 9 and it is currently the only qualitative, patient-based test that specifically measures walking disabilities. The MSWS-12 is easy to administer in a clinical setting for measuring walking difficulties in daily life, and it has been translated into various languages and validated as a useful tool in MS. [10][11][12][13][14] However, the MSWS-12 has not been validated for Korean MS patients, and moreover its applicability has not been evaluated for patients with NMOSD. The aim of this study was to adapt and validate a Korean version of the MSWS-12 for the Korean population with MS and NMOSD.…”

Background and Purpose Gait problems are a primary complaint in patients with multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD). The 12-item Multiple Sclerosis Walking Scale (MSWS-12) is a patient-reported measure assessing the impact of MS on the walking ability. We aimed to adapt and validate the Korean version of the MSWS-12 for the Korean population with MS and NMOSD. Methods Thirty-four MS and 35 NMOSD patients were recruited. The MSWS-12 questionnaire was translated into the Korean language and evaluated for its validity and reliability in these patients. Results The MS and NMOSD patients had mean ages of 35.9 and 42.1 years, respectively, median disease durations of 5.6 and 7.2 years, median Expanded Disability Status Scale (EDSS) scores of 2.75 (range, 0-6.5) and 3.5 (range, 0-7.5), and median baseline MSWS-12 total scores of 25 [interquartile range (IQR), 2.60-53.65] and 25 (IQR, 7.29-50.00). The baseline MSWS-12 total score in the patients with MS showed strong correlations with scores for the EDSS, timed 25-foot walk (T25FW), Multiple Sclerosis Impact Scale-29 (MSIS-29) physical dimension, and 36-item Short-Form Health Survey (SF-36) physical component summary (PCS), with Spearman's correlation coefficients (ρ) of 0.922, 0.756, 0.933, and-0.874, respectively. In patients with NMOSD, the baseline MSWS-12 total score showed strong correlations with scores for the EDSS, MSIS-29 physical dimension, and SF-36 PCS (ρ=0.769, 0.910, and-0.852, respectively), and moderate correlations with scores for the T25FW and Fatigue Severity Scale-9 (ρ=0.597 and 0.630, respectively). Conclusions The Korean version of the MSWS-12 appears to be a valid and reliable scale that can be used for Korean patients with MS. The MSWS-12 can also be applied to patients with NMOSD.
