Magnetic stimulation of the abducens nerve reduces sixth nerve palsy after brain hemorrhage: case series

Magnetic stimulation has been explored for various neurological disorders, yet its application for abducens nerve paralysis, which often results from brain hemorrhage and severely impairs ocular mobility and quality of life, remains unclear. The report included three cases of eye abduction disorders secondary to brain hemorrhage: two brainstem and one temporal lobe hemorrhage. All cases were treated with 1 -Hz magnetic stimulation applied to the abducens nerve for 4–10 days, according to their medical history and clinical manifestations. All cases showed immediate significant improvements in ocular abduction movements following treatment. Walking function, hand-eye coordination, and daily living activities were also significantly enhanced, with a notable increase in self-reported life satisfaction. These cases suggest that magnetic stimulation might offer a promising avenue for treating abducens nerve paralysis, especially where traditional approaches prove ineffective. The observed outcomes highlight the versatility of magnetic stimulation as a treatment modality and its potential applicability to other cranial nerve dysfunctions. This case series underscores the potential efficacy of magnetic stimulation in treating abducens nerve paralysis, warranting more extensive studies to establish its safety, optimal parameters, and long-term benefits.
