Vagus nerve stimulation combined with nerve rehabilitation therapy for upper limb paralysis after hemorrhagic stroke: a stroke-related epilepsy case

Abstract

Background: Hemorrhagic stroke has a high incidence, often leaving patients with significant complications such as limb mobility disorders after treatment. Traditional treatment methods for stroke patients mainly include limb function exercises and hyperbaric oxygen therapy, which have shown effective results. In recent years, there have been reports utilizing vagus nerve stimulation (VNS) to treat limb paralysis in ischemic stroke patients, achieving encouraging outcomes. However, there are rare related reports on hemorrhagic stroke. Case presentation: This report presents a case of a patient who developed left upper limb hemiplegia and recurrent seizures after a hemorrhagic stroke. The patient showed a poor response to standard anti-epileptic treatment and was diagnosed with stroke-related epilepsy. To manage the recurrent seizures, VNS was performed. After the device was activated, the patient reported a significant reduction in abnormal muscle tone and increased mobility impairment in the affected upper limb. Parameters were adjusted, and intermittent stroke electrical stimulation was combined with upper limb rehabilitation exercises. After three months of active treatment, the patient’s seizures were well controlled, and there was significant improvement in upper limb function. Conclusions: VNS has potential in the rehabilitative treatment of stroke patients with upper limb dysfunction. It is hoped that more patients will benefit from this advanced treatment method in the future, regaining their health and vitality. Additionally, future research needs to further explore the mechanisms and methods of brain remodeling to provide theoretical support and more effective treatment options for stroke patient rehabilitation.
