Purpose. People with Multiple Sclerosis (PwMS) tent to have increased levels of fatigue which can impact on their balance and increase risk of falls. However, the relationship between fatigue and balance is poorly understood. The aim of the present study was to assess if an experimentally induced fatigue had an immediate effect on balance. Methods. 37 inpatients with multiple sclerosis were recruited; the mean age (standard deviation) was 48.7 (9.6) years. The average onset of the pathology was 15.3 (9.8) years before the start of the study. The median (1°–3° quartile) Expanded Disability Status Scale (EDSS) score was 5.5 (4.5–6.0). Before and after a fatiguing treadmill, session, subjects were assessed with the Berg Balance Scale and Dynamic Gait Index. Results. After the treadmill, no statistically significant differences were found in balance before and after a treadmill session (monopodalic stance: before 5.3s (10.3) and after 7.7s (13.9); walk with horizontal head turns: before 11.6 (6.9) seconds and after 11.3 (7.7)). There was no correlation between the EDSS score and the difference in balance skills before and after treadmill. Conclusion. After treadmil PwMS were mentally and physically fatigued; however, their balance performance did not change, indicating no increase in risk of falling with fatigue.
