Pulmonary complications are the major causes of morbidity and mortality for persons with cervical spinal cord injury. Diminished ability to cough constitutes a major contribution to the high incidence of pulmonary morbidity in this population. This article reports preliminary results for a new technique for providing assisted cough in this population. In this study, efficacy of cough (as measured by peak expiratory flow rate) was measured under three conditions: volitionally with no assistance, with manual assist of a therapist, and with electrical stimulation of abdominal muscles. Coughs produced by electrical stimulation were approximately as effective as manually assisted coughs. The results suggest this technique is worthy of more detailed study and may be a potentially effective new modality for assisting spinal cord injured persons to clear their airways.
肺部并发症是颈脊髓损伤患者发病和死亡的主要原因。咳嗽能力下降是该人群肺部发病率高的主要原因。本文报告了一种为该人群提供辅助咳嗽的新技术的初步结果。在本研究中，在三种情况下测量咳嗽的效果（通过呼气峰值流速测量）：无辅助自主咳嗽、治疗师手动辅助咳嗽以及腹部肌肉电刺激咳嗽。电刺激产生的咳嗽效果与手动辅助咳嗽大致相同。结果表明，该技术值得更详细的研究，可能是协助脊髓损伤患者清理气道的一种潜在有效新方法。
