Decreased functional mobility in individuals with mild to moderate expanded disability status from relapsing multiple sclerosis: Analysis of the Glittre-ADL test.

Abstract

Introduction: Multiple sclerosis (MS) is a chronic inflammatory and autoimmune disease that significantly limits an individual's activities of daily living (ADLs) and negatively affects their social participation as it progresses. The impact of activities and participation must be continuously assessed, and the Glittre-ADL is a validated test for MS to assess functional capacity in tasks similar to ADLs.

Objective: To evaluate whether the Glittre-ADL test is a valid method for assessing functional mobility in individuals with MS and moderate disability or those who use assistive devices.

Methods: This cross-sectional study enrolled 30 individuals in two groups: 1) MS group (n = 15); and 2) healthy control group (n = 15). The MS group underwent three functional mobility tests: 1) Glittre-ADL; 2) Timed 25-Foot Walk (T25FWT); and 3) Timed Up and Go (TUG) while the healthy group underwent only the Glittre-ADL test.

Results: An association was found between the Glittre-ADL time and T25FWT (r = 0.78, p < .001) and TUG (r = 0.56, p = .030) times. In the MS group, statistically significant differences were found in time (F = 2.88, p = .038) and speed (F = 5.17, p = .024) between laps. A statistically significant difference was observed between the total time in the MS and control groups (Area Under Curve - AUC: 0.982, p < .0001). A total time > 46.0s represents the reduction of functional performance during ADLs in individuals with MS (sensitivity: 93.3%; specificity: 92.2%).

Conclusion: The Glittre-ADL test is a valid tool for assessing functional mobility in individuals with MS and mild to moderate disability (EDSS score ≤ 6.5).
