One problematic and undertreated consequence of spinal cord injury (SCI) is urinary dysfunction. Treatment is usually conservative, involving regulation of fluid intake and scheduled bladder emptying through intermittent catheterization. These interventions provide symptomatic relief but are associated with recurrent urinary tract infections and increased risk of kidney disease. Neuromodulation has been used to counteract aberrant signals, such as bladder overactivity, but has yet to address other symptoms, such as urethral sphincter tonic activity or poor bladder compliance. Combining rehabilitation with vagus nerve stimulation (VNS), which is known to engage neuromodulatory nuclei to promote synaptic neuroplasticity and recovery, has emerged as a potential therapy to restore function after neurological injury including SCI. Our perspective is that a congruent strategy of pairing VNS with bladder function after incomplete SCI can promote neuroplastic changes in spared neural pathways to strengthen neural control of bladder function.
脊髓损伤(SCI)的一个存在问题且未得到充分治疗的后果是排尿功能障碍。治疗通常是保守的,包括调节液体摄入量以及通过间歇性导尿定期排空膀胱。这些干预措施可缓解症状,但与复发性尿路感染及肾病风险增加有关。神经调节已被用于对抗异常信号,如膀胱过度活动,但尚未解决其他症状,如尿道括约肌紧张性活动或膀胱顺应性差。将康复与迷走神经刺激(VNS)相结合,已知VNS可激活神经调节核以促进突触神经可塑性和恢复,已成为一种在包括SCI在内的神经损伤后恢复功能的潜在疗法。我们的观点是,在不完全性SCI后将VNS与膀胱功能配对的一致策略可以促进保留神经通路中的神经可塑性变化,以加强对膀胱功能的神经控制。
