Effect of Electrical Stimulation on Remyelination in Animal Models of Multiple Sclerosis
A systematic review of six animal studies found that electrical stimulation (ES) improved remyelination, indicated by reduced visual evoked potential (VEP) latency and increased myelin protein expression. Different types of electrical stimulation, such as transcranial direct current stimulation (tDCS) and vagus nerve stimulation (VNS), showed varying effects on oligodendrocyte maturation and inflammation modulation.

Results in cells or animals often do not carry over to people with MS.
Why it matters
These findings suggest that ES can potentially enhance remyelination in multiple sclerosis by acting on neuronal and inflammatory pathways, which is significant for developing future therapies.
What this does not prove
The evidence is limited and preclinical, and standardized protocols for stimulation and imaging are necessary for translating these findings to clinical practice. No human efficacy has been demonstrated yet.

subjectsin vivo studies investigating ES in demyelinating animal models.
sample sizeRESULTS: Six eligible studies met the inclusion criteria, comprising EAE, cuprizone, and lysolecithin lesion models.
findingsES was associated with improvements in indices of remyelination, evidenced by reduced VEP latency, and increased myelin protein expression.
findingsEffects of tDCS depended on polarity and timing, with anodal stimulation supporting oligodendrocyte maturation during recovery and cathodal stimulation attenuating glial activation during inflammation.
findingsVNS promoted remyelination through anti-inflammatory and trophic signaling, and PNS supported spinal remyelination via peripheral to central neuroimmune modulation.
limitationsLimited but convergent preclinical evidence suggests ES may enhance remyelination by modulating neuronal and inflammatory pathways.
limitationsHowever, standardized protocols of stimulation and multimodal imaging studies are needed for clinical translation in MS.
