The basic hemodynamics of masseter muscle was investigated to clarify the cause of pain and fatigue of masseter muscle. The first purpose of this investigation is to confirm the application of near infrared spectroscopy (NIRS) in the human masseter muscle. Hemodynamics of masseter muscle is examined regarding the point of sensor positioning, circadian, ultradian rhythms, intergeneration sex difference and maximum voluntary clenching using NIRS. Simultaneously ultrasonographic appearances were studied in female patients with temporomandibular disorder (TMD) associated with myofascial pain in comparison with healthy volunteers. The ultrasonographic features were clarified and they might be related to muscle edema. Furthermore, changes of hemodynamics were examined with a NIRS after transcutaneous electrical nerve stimulation (TENS). In clinical cases, we verified efficacy of stabilization splint for patients with TMD. Coronoid process hyperplasia were also investigated with CT. In conclusion, the ultrasonography and NIRS appeared to be a promising tool for evaluation of the muscle in patients with TMD.

为阐明咬肌疼痛和疲劳的原因，对咬肌的基本血流动力学进行了研究。本研究的第一个目的是确认近红外光谱(NIRS)在人体咬肌中的应用。用近红外光谱检测咬肌的血流动力学，包括传感器位置、昼夜节律、超常节律、代际性别差异和最大程度的自主咬合。同时，对伴有肌筋膜痛的女性颞下颌关节紊乱病(TMD)的超声表现进行了研究，并与健康志愿者进行了比较。声像图特征明确，可能与肌肉水肿有关。用近红外光谱检测经皮神经电刺激(TENS)后血流动力学的变化。在临床病例中，我们验证了稳定夹板对TMD患者的疗效。同时行CT扫描，观察冠状突增生症。综上所述，超声和近红外光谱技术是评估TMD患者肌肉功能的一种有前景的工具。
