Abstract：
UNASSIGNED: The main objective of this study is to test the reliability of a non-invasive objective method for the measurement of biomechanical parameters of cervicofacial muscle groups, with the purpose of diagnosis and evaluation of voice disorders\' treatments, especially focused on muscle tension dysphonia.
UNASSIGNED: Prospective study.
UNASSIGNED: The device used is a handheld myotonometer (MyotonPRO) that measures biomechanical and viscoelastic properties in superficial soft tissues frequency, stiffness, elasticity, relaxation time and creep. It is used in the field of medicine, sport and research. This pilot study includes 10 subjects, who have been measured in the masseter, sternocleidomastoid, orbicularis oris, semispinalis capitis, suprahyoid, infrahyoid and trapezius muscles on each side. Measurements were performed by 2 evaluators to assess inter-evaluator reliability. Subsequently, one of them repeated the measurements to assess intra-evaluator reliability.
UNASSIGNED: The results revealed good to excellent inter-rater reliability for the masseter, sternocleidomastoid, trapezius and suprahyoid muscles, with lower ICCs for the stiffness and creep properties. Intra-rater reliability was good to excellent for the masseter, sternocleidomastoid, semispinalis capitis and suprahyoid muscles. The lowest ICCs were found in the stiffness and creep properties.
UNASSIGNED: The use of a myotonometer to measure the mechanical properties of selected cervical and orofacial muscles is a reliable and reproducible method. Future research is needed to establish an association between the properties of these muscles and their role in voice disorders, as well as to determine whether this tool can aid diagnosis with quantifiable and objectifiable indicators, and for monitoring and treatment efficacy.

摘要：
■这项研究的主要目的是测试一种用于测量颈面部肌群生物力学参数的非侵入性客观方法的可靠性，以诊断和评估嗓音障碍的治疗为目的，特别是集中在肌肉紧张的发声障碍。
■前瞻性研究。
■使用的设备是手持式肌测量计（MyotonPRO），用于测量浅层软组织频率中的生物力学和粘弹性特性，刚度,弹性,放松时间和蠕变。它用于医学领域，体育和研究。这项试点研究包括10个主题，在咬肌中测量过的人，胸锁乳突,口轮匝肌,半壁肌炎，舌骨上,舌骨下和斜方肌每侧。由2名评估者进行测量以评估评估者间的可靠性。随后，其中一个重复测量以评估评估者内部的可靠性。
■结果显示，咬肌的评分者间可靠性良好，胸锁乳突,斜方肌和舌骨上肌，刚度和蠕变性能的ICC较低。对咬肌来说，评分器内部的可靠性很好到很好，胸锁乳突,半壁肌头炎和舌骨上肌。在刚度和蠕变性能中发现最低的ICC。
■使用肌压计测量选定的颈部和口面部肌肉的机械性能是一种可靠且可重复的方法。未来的研究需要在这些肌肉的特性和它们在语音障碍中的作用之间建立关联，以及确定该工具是否可以通过可量化和客观的指标来帮助诊断，以及监测和治疗效果。
