The laryngeal function of 19 severely closed head-injured subjects with a perceptible dysarthria was assessed using electrolaryngography and a computerized airflow/air pressure analysis system (Aerophone II). Variables measured included parameters of the Lx waveform (Fo, duty cycle and closing time) as well as aerodynamic parameters such as subglottal pressure, glottal resistance, average phonatory sound pressure level, phonatory flow rate and ad/abduction rate. Values were compared to those recorded from a non-neurologically impaired control group matched for age and sex, and correlated with the findings of a perceptual speech analysis. The findings are discussed in relation to the effects of a severe closed-head injury on laryngeal function. The clinical implications of the findings for the assessment and treatment of vocal dysfunction in head-injured subjects are also discussed.
使用电子喉描记法和计算机气流/气压分析系统（Aerophone II）对19名有明显构音障碍的重度闭合性颅脑损伤患者的喉部功能进行了评估。测量的变量包括Lx波形的参数（基频、占空比和闭合时间）以及诸如声门下压力、声门阻力、平均发声声压级、发声流速和内收/外展率等空气动力学参数。将这些值与来自年龄和性别匹配的无神经功能障碍对照组记录的值进行比较，并与感知语音分析的结果相关联。讨论了这些发现与重度闭合性颅脑损伤对喉部功能的影响之间的关系。还讨论了这些发现对颅脑损伤患者声带功能障碍评估和治疗的临床意义。
