We tested the hypothesis that the pattern of chest wall configuration during speech production correlates with the pattern of chest wall motion during resting breathing. Twenty-one men (age 40 +/- 8 years) with ankylosing spondylitis and varied degrees of ribcage involvement participated in the study. None of the patients had an obvious speech abnormality. Ribcage and abdominal displacements during quiet breathing and during reading were measured with a respiratory plethysmograph. Measurements were taken in the sitting and standing body positions. In each body position, ribcage or abdominal displacements during quiet breathing correlated with the corresponding chest wall displacements recorded during reading (P < 0.001). In addition, linear regression analysis showed that the slope of the chest wall motion loop during quiet breathing correlated with the ratio of ribcage to abdomen contribution to lung volume displacement during reading (r = 0.78, P < 0.001 for sitting and r = 0.64, P = 0.002 for standing position). The slopes of the regression lines did not differ between the sitting and standing body position (P > 0.05). We conclude that the relative contribution of the ribcage and abdomen to lung volume displacement during speech production correlates with the relative ribcage and abdomen contribution to tidal volume during quiet breathing; our data support the notion that the pattern of chest wall configuration during quiet breathing largely predicts the pattern of ribcage and abdomen displacement during speech.
言语产生过程中胸壁构型模式与静息呼吸时胸壁运动模式相关。21名患有强直性脊柱炎且胸廓受累程度不同的男性（年龄40±8岁）参与了该研究。所有患者均无明显的言语异常。使用呼吸体积描记器测量静息呼吸和阅读过程中的胸廓及腹部位移。测量在坐姿和站姿下进行。在每种体位下，静息呼吸时的胸廓或腹部位移与阅读过程中记录的相应胸壁位移相关（P<0.001）。此外，线性回归分析表明，静息呼吸时胸壁运动环的斜率与阅读过程中胸廓与腹部对肺容积位移的贡献比相关（坐姿时r = 0.78，P<0.001；站姿时r = 0.64，P = 0.002）。回归线的斜率在坐姿和站姿之间无差异（P>0.05）。我们得出结论，言语产生过程中胸廓和腹部对肺容积位移的相对贡献与静息呼吸时胸廓和腹部对潮气量的相对贡献相关；我们的数据支持这样一种观点，即静息呼吸时胸壁构型模式在很大程度上可预测言语过程中胸廓和腹部的位移模式。
