Unipolar phrenic nerve stimulation (diaphragm pacing) has been used for ventilation of patients with C2 tetraplegia. Four-pole sequential nerve stimulation delays muscle fatigue when compared with unipolar stimulation. This may help to achieve more frequently long-term full-time bilateral electroventilation. Four-pole sequential nerve stimulation also offers an opportunity to shorten the conditioning phase of the hypotrophic diaphragm from about 6 to 2 months. The new conditioning regimen was tested successfully in two patients with C2 tetraplegia. The new stimulation method and conditioning regimen remarkably shorten the time after injury during which mechanical ventilation is needed. This will give the patients earlier access to rehabilitation centres for spinal cord injuries and will diminish the work load of the personnel.
单极膈神经刺激（膈肌起搏）已用于C2四肢瘫痪患者的通气。与单极刺激相比，四极顺序神经刺激可延迟肌肉疲劳。这可能有助于更频繁地实现长期全时双侧电通气。四极顺序神经刺激还提供了一个机会，将萎缩膈肌的适应期从约6个月缩短至2个月。新的适应方案在两名C2四肢瘫痪患者中得到了成功测试。新的刺激方法和适应方案显著缩短了受伤后需要机械通气的时间。这将使患者能更早地进入脊髓损伤康复中心，并减轻工作人员的工作量。
