PurposeThe目的本研究的目的是确定预测腭帆提肌（LVP）肌肉缩短和最大收缩速度在成年人正常anatomy.MethodTwenty-two高加索英语为母语的成年人正常的语音和共振被招募。参与者包括11名男性和11名女性（M= 22.8岁，SD= 4.1），解剖结构正常。使用三维静态成像协议获得静态磁共振图像。建立正中矢状面和斜冠状面，以观察静息时的帆和LVP肌肉。在制作“袢”的过程中，在斜冠状面获得动态磁共振图像。Amira 6.0.1可视化和体积建模软件和MATLAB被用来分析图像，并计算LVP缩短和最大收缩velocity.ResultsSignificant预测（p<0.05）的最大LVP缩短在腭咽闭合包括平均extravelar长度，LVP原点到原点的距离，软腭厚度，咽深度，和腭咽比。显著的预测因子（p< .05），最大收缩速度包括平均extravelar长度，intravelar长度，LVP原点到原点的距离，和软膜thickness. Conclusions本研究确定了6个real-time语音过程中预测LVP肌肉功能的real-time咽变量。这些预测因素应考虑在儿童和个人修复腭裂在未来的研究。
PurposeThe purpose of this study was to identify predictors of levator veli palatini (LVP) muscle shortening and maximum contraction velocity in adults with normal anatomy.MethodTwenty-two Caucasian English-speaking adults with normal speech and resonance were recruited. Participants included 11 men and 11 women (M= 22.8 years,SD= 4.1) with normal anatomy. Static magnetic resonance images were obtained using a three-dimensional static imaging protocol. Midsagittal and oblique coronal planes were established for visualization of the velum and LVP muscle at rest. Dynamic magnetic resonance images were obtained in the oblique coronal plane during production of “ansa.” Amira 6.0.1 Visualization and Volume Modeling Software and MATLAB were used to analyze images and calculate LVP shortening and maximum contraction velocity.ResultsSignificant predictors (p< .05) of maximum LVP shortening during velopharyngeal closure included mean extravelar length, LVP origin-to-origin distance, velar thickness, pharyngeal depth, and velopharyngeal ratio. Significant predictors (p< .05) of maximum contraction velocity during velopharyngeal closure included mean extravelar length, intravelar length, LVP origin-to-origin distance, and velar thickness.ConclusionsThis study identified six velopharyngeal variables that predict LVP muscle function during real-time speech. These predictors should be considered among children and individuals with repaired cleft palate in future studies.
