Ten men with cervical spinal cord injury were studied using magnetometers to record surface motions of the chest wall during speech breathing. Individual speech breathing patterns reflected inspiratory and expiratory muscular sparing. Subjects compensated for expiratory muscle impairment by speaking at large lung volumes, presumably to take advantage of the higher recoil pressures available at those volumes. Similarly, subjects used larger lung volumes to increase loudness. Abnormal chest wall behavior was attributed in large part to loss of abdominal muscle function. Because of this, speech breathing in individuals with cervical spinal cord injury may be improved by the use of abdominal binders.
对10名颈脊髓损伤患者进行了研究，使用磁力计记录言语呼吸期间胸壁的表面运动。个体的言语呼吸模式反映了吸气和呼气肌肉的保留情况。受试者通过在较大肺容量时说话来补偿呼气肌无力，推测是为了利用这些容量下更高的回缩压力。同样，受试者使用更大的肺容量来提高响度。胸壁异常行为在很大程度上归因于腹肌功能丧失。因此，使用腹部束缚带可能会改善颈脊髓损伤患者的言语呼吸。
