Associations between fatigue impact and physical and neurobehavioural factors: An exploration in people with progressive multiple sclerosis.

BACKGROUND

Fatigue is common in people with multiple sclerosis (MS). Understanding the relationship between fatigue, physical and neurobehavioural factors is important to inform future research and practice. Few studies explore this explicitly in people with progressive MS (pwPMS).

OBJECTIVE

To explore relationships between self-reported fatigue, physical and neurobehavioural measures in a large, international progressive MS sample of cognitively impaired people recruited to the CogEx trial.

METHODS

Baseline assessments of fatigue (Modified Fatigue Impact Scale; MFIS), aerobic capacity (VO

STATISTICAL ANALYSIS

Differences in individuals categorised as fatigued or non-fatigued were assessed (t-tests, chi square). Pearson's correlation and partial correlations (adjusted for EDSS score, country, sex, and depressive symptoms) determined associations with MFIS

RESULTS

The sample comprised 308 pwPMS (62 % female, 27 % primary progressive, 73 % secondary progressive), mean age 52.5 ± 7.2 yrs, median EDSS score 6.0 (4.5-6.5), mean MFIS
