Thoracolumbar corsets are used to manage stable uncomplicated injuries of the spine. The effects of these corsets on breathing pattern either in normal individuals or in patients with spinal injuries are not known. This study determined the effects of wearing a thoracolumbar corset on breathing patterns. Eight healthy, young, non-smoking women students participated by fully informed voluntary consent. Selected ventilatory parameters were monitored in supine and sitting positions immediately before and after wearing the corset, after wearing the corset for 1 h and immediately after removal of the corset. Ventilatory variables were monitored by connecting the facemask to the Cortex MetaMax (Biophysik GmgH) data collection system. Normalized data were subjected to MANOVA (P<0.05). Wearing the corset for 1 h significantly decreased tidal volume (Vt) by 24% and increased breathing frequency (Fb) by 19% in the sitting compared to the control condition. Participants who had been wearing the corset for 1 h had significantly lower Vt in the supine position compared to the sitting position. We conclude that when a corset is worn for at least 1 h, Vt and Fb change to maintain the minute ventilation. More research is indicated to determine the effects of wearing a corset for longer than 1 h on pulmonary variables in patients.
胸腰段矫形器用于处理稳定且不复杂的脊柱损伤。这些矫形器对正常个体或脊柱损伤患者呼吸模式的影响尚不清楚。本研究确定了佩戴胸腰段矫形器对呼吸模式的影响。八名健康、年轻、不吸烟的女学生在充分知情并自愿同意的情况下参与了研究。在佩戴矫形器之前和之后、佩戴矫形器1小时后以及取下矫形器后立即，分别在仰卧位和坐位监测选定的通气参数。通过将面罩连接到Cortex MetaMax（Biophysik GmgH）数据采集系统来监测通气变量。对标准化数据进行多变量方差分析（P<0.05）。与对照情况相比，佩戴矫形器1小时后，坐位时潮气量（Vt）显著降低24%，呼吸频率（Fb）增加19%。佩戴矫形器1小时的参与者在仰卧位时的Vt显著低于坐位。我们得出结论，当佩戴矫形器至少1小时时，Vt和Fb会发生变化以维持分钟通气量。需要更多研究来确定佩戴矫形器超过1小时对患者肺部变量的影响。
