Home treatment against fatigue in multiple sclerosis by a personalized, bilateral whole-body somatosensory cortex stimulation

Background: Fatigue in multiple sclerosis (MS) is a highly invalidating symptom with no pharmacological efficacious therapies, which furthermore present frequent severe side effects. In two previous randomized controlled trials we observed the efficacy of a personalized neuromodulation treatment consisting of a personalized transcranial Direct Current Stimulation (tDCS) for 15 min per day for 5 days (Faremus).Methods: By this medical-device phase II study, we aimed at assessing the feasibility, acceptance, safety and efficacy of Faremus treatment when applied at patients' home. We considered the efficacy as primary outcome assessed by a reduction of fatigue levels measured by Modified Fatigue Impact Scale (mFIS) scored before and after the treatment. Primary outcome determined the sample size estimate. Individual ad-hoc questionnaires quantified the acceptance, safety and side effects during the treatment.Results: : All 15 patients completed the treatment, reporting optimal acceptance and safety on using Faremus at their home without side-effects. The treatment ameliorated fatigue symptoms more than 20% of baseline in 10 out of the 15 patients and of 37% on average, with a corresponding effect size 1.21.Conclusions: : Faremus personalized electroceutical intervention, a 5-days anodal tDCS over the bilateral whole body somatosensory cortex, is well accepted and can be feasibly, safely, and efficaciously applied at patients' home, offering a comfortable treatment by reducing the need to travel when fatigue-related symptoms hamper the quality of life.

Automated summary

Faremus, a personalized neuromodulation treatment, was found to be safe and effective when applied at patients' home, improving fatigue symptoms and offering a comfortable treatment option.
