Disability and Fatigue in Multiple Sclerosis: Can Rehabilitation Improve Them through a Structured Retraining...

Functional rehabilitation programs in multiple sclerosis have demonstrated their efficacy in improving fatigue. The assessment of functional impairment, however, is more difficult. The purpose is to assess fatigue and disability as a first study measure and to verify their improvement after a specific functional rehabilitation program. An analytical, longitudinal, prospective, and experimental study was carried out with 51 patients aged 18-55 years, with an Expanded Disability Status Scale (EDSS) between 2 and 6.5 who were being followed up in outpatient clinics of the Rehabilitation Service of La Princesa Hospital. The fatigue and disability outcomes before and after a structured exercise training program were evaluated, with each subject acting as their own control. The variables were measured using the Modified Fatigue Impact Scale (MFIS), Barthel Index (BI), and Functional Independence Scale (FIM). Differences according to recurrent or progressive course of the disease are assessed. Improvement in the FIM scale was observed after the retraining program (p = 0.016) and was maintained in the medium term (p = 0.042). This improvement is not statistically significant in Barthel Index. Improvement in MFIS is observed after the program (p < 0.001) and 4-6 months after the end. Both disease courses experience the same improvements with no statistically significant differences between them. The retraining program improves fatigue and multiple sclerosis-related functionality in the short and medium term. There are no differences according to disease course. Both experience the same positive changes with our intervention.
