Virtual Reality - Gamma Sensory Stimulation for Improving Fatigue in People With Multiple Sclerosis

Gamma Sensory Stimulation (GSS) for Improving Fatigue in People With Multiple Sclerosis

Source: ClinicalTrials.gov · Last updated 22 Oct 2026

Brief summary (registry, in English)

This is a double-blind, parallel, randomized, sham-controlled pilot study evaluating the safety, feasibility, and efficacy of Gamma Sensory Stimulation (GSS) delivered via a Virtual Reality (VR) headset in individuals with Multiple Sclerosis (MS) who experience moderate to severe fatigue. Participants will be randomized (1:1) to 4 weeks of active GSS or sham stimulation, followed by a 4-week post-treatment follow-up. The primary objective is to determine whether GSS reduces fatigue, measured by the Modified Fatigue Impact Scale (MFIS). Secondary outcomes include additional fatigue scales, cognitive performance, quality-of-life measures, tolerability and safety.

  • Participation in other experimental studies within the previous 90 days prior to screening visit.
  • Patients having a pacemaker or other metal implants.

Other illness

  • Any condition or therapy impairing trial participation and assessments.
  • Severe systemic diseases or history of cancer or hereditary familiar cancer.
  • A history of seizure or epilepsy.
  • Dementia or severe psychiatric, cognitive or behavioral problems or other comorbidity that may interfere with the compliance to the protocol.

Who the study is looking for

  • Be between 18 to 65 years of age (inclusive) on the day of signing informed consent.
  • Have MS (McDonald criteria 2017) with Modified Fatigue Impact Scale (MFIS) score greater than 33 OR fatigue greater than 4 (out of 7) on the Fatigue Severity Scale (FSS).
  • Sufficient hearing and vision.
  • Any type of disease modifying therapy is allowed and should be stable in the last 3 months.
  • Not having received corticosteroids the previous month.
  • Each subject must sign the informed consent form, in accordance with local requirements, after the scope and nature of the investigation have been explained to the subject, and before Screening assessments.
