80% of people with MS experience fatigue without any effective treatments. This type of fatigue is different from being tired — it’s neurological, persistent, and often disabling.
How Phototherapy Helps
How NB-UVB Light Supports Immune Regulation and Energy
Cytokind, in collaboration with the Kids Research Institute of Australia and Octave BioSciences, Inc., is the first to correlate MS fatigue to inflammation and measure the beneficial effects of NB-UVB—offering the promise of a non-drug option for patients.
-
Measurements of FatigueThere are numerous questionnaires to qualify MS fatigue. Our research used the Fatigue Severity Scale (FSS) score, a 9-question online survey.
-
NB-UVB Therapy & FatigueIt helps balance the immune response, including reducing inflammation and fatigue. NB-UVB significantly expanded regulatory T-cells, reduced switch-memory B-cells. In the PhoCIS trial, the FSS was significantly correlated with NB-UVB and reduced MS disease activity.
