A physiological analysis of the lip and tongue function of a group of 18 severely closed-head injured (CHI) subjects was performed using lip and tongue force transduction systems. Lip and tongue strength, endurance and rate of repetitive movements were assessed on four non-speech tasks: maximum strength, sustained maximum strength, repetition of 10 maximum strength compressions, and maximum repetition rate. The values recorded were compared to those achieved by a group of 18 non-neurologically impaired subjects, matched for age and sex, who served as the controls. The results of the study indicated that the CHI subjects demonstrated a significant impairment of lip and tongue function based on strength, endurance and rate of repetitive movements, compared to the controls. While lip function was found to be significantly impaired on several measures of strength and endurance, tongue function was noted to be more severely compromised. The CHI subjects were found to exhibit a significantly reduced rate of repetitive movements of the lips and tongue. The results are discussed in relation to the effects of CHI on neuromuscular function and differential subsystem impairment in dysarthria. The clinical implications of these findings are also discussed in relation to the treatment of articulatory disturbances following severe CHI.
使用唇部和舌部力传导系统，对一组18名重度闭合性颅脑损伤（CHI）患者的唇部和舌部功能进行了生理分析。在四项非言语任务中评估了唇部和舌部的力量、耐力及重复运动速率：最大力量、持续最大力量、10次最大力量压缩的重复动作以及最大重复率。将记录的值与一组18名年龄和性别匹配的非神经功能受损受试者（作为对照组）所取得的值进行比较。研究结果表明，与对照组相比，CHI患者在力量、耐力和重复运动速率方面表现出唇部和舌部功能的显著受损。虽然在力量和耐力的多项测量中发现唇部功能有显著受损，但舌部功能受损更为严重。发现CHI患者唇部和舌部的重复运动速率明显降低。结合CHI对神经肌肉功能的影响以及构音障碍中不同子系统损伤对研究结果进行了讨论。还结合重度CHI后发音障碍的治疗对这些发现的临床意义进行了讨论。
