To assess the longitudinal association between respiratory muscle strength and cough capacity in persons with recent spinal cord injury.
Longitudinal analyses.
Forty persons with recent spinal cord injury and impaired pulmonary function.
Measurements were performed 4 weeks after the start of rehabilitation, 9 and 17 weeks after the first measurement, and one year after discharge from inpatient rehabilitation. Peak cough flow was measured with a spirometer. Maximum inspiratory and expiratory pressures (MIP and MEP), expressed in cmH2O, were measured at the mouth.
Both MIP and MEP were significantly positively associated with peak cough flow. After correction for confounders and time 10 cmH2O higher MIP was associated with a 0.32 l/s higher peak cough flow, and a 10 cmH2O higher MEP was associated with a 0.15 l/s higher peak cough flow. The association between MIP and peak cough flow was mainly based on within-subject variance. The association between MIP and peak cough flow was stronger than between MEP and peak cough flow.
Improvement in respiratory muscle strength is associated with improvement in cough capacity in persons with recent spinal cord injury who have impaired pulmonary function.
评估近期脊髓损伤患者呼吸肌力量与咳嗽能力之间的纵向关联。
纵向分析。
40例近期脊髓损伤且肺功能受损的患者。
在康复开始后4周、首次测量后9周和17周以及住院康复出院后1年进行测量。使用肺活量计测量峰值咳嗽流量。在口腔处测量以厘米水柱（cmH2O）表示的最大吸气和呼气压力（MIP和MEP）。
MIP和MEP均与峰值咳嗽流量显著正相关。在校正混杂因素和时间后，MIP每升高10 cmH2O，峰值咳嗽流量增加0.32 l/s，MEP每升高10 cmH2O，峰值咳嗽流量增加0.15 l/s。MIP与峰值咳嗽流量之间的关联主要基于个体内差异。MIP与峰值咳嗽流量之间的关联比MEP与峰值咳嗽流量之间的关联更强。
对于近期脊髓损伤且肺功能受损的患者，呼吸肌力量的改善与咳嗽能力的改善相关。
