项目摘要
The purpose of this study was to clarify whether physical therapies and occlusal splints are effective against muscle fatigue of temporomandibular disorders (TMD) patients from the point of view of blood flow state.<Methods>Blood flow of masseter muscles were measured using 3-wave-length near-infrared spectroscopy, and the blood flow parameters were total hemoglobin volume (THb), oxygenated hemoglobin volume (OXHb), deoxygenated hemoglobin volume (deOXHb), and oxygen saturation level (StO2). Subjects for the physical therapies were healthy subjects with no history of muscle pain in the masticatory system, while subjects for the splint therapy were TMD patients with masticatory muscle symptoms who used stabilization splints. The physical therapies applied were 20-minite hot pack and 30-minite myo-monitor.<Results and discussion>1)THb,OXHb and StO2 after the hot pack application were significantly larger than those during resting. The deOXHb showed no significant difference between the values before and after the hot pack application. The results suggest that the blood flow state of human masseter muscles can be influenced by a hot pack, and that the effect of hot pack therapy is to increase regional blood volume and that it creates the advantageous conditions for aerobic energy metabolism.2)There was no no significant difference between the values before and after myo-monitor application in all parameters of blood flow.3)During resting, mean values of StO2 with the splint were significantly larger than those without the splint During and after clenching, THb with the splint was significantly larger than that without the splint. The results suggest that the blood flow of masseter muscles can be influenced by wearing stabilization splints in the short term. However, effect of longtime using of splints is still unknown. Further studies on longitudinal change in blood flow stale of masticatory muscles in wearing splints are needed.
这项研究的目的是澄清物理疗法和咬合夹板是否有效地抵抗颞下颌疾病(TMD)患者(TMD)患者的肌肉疲劳是否是从血流状态的角度进行的。 (OXHB),脱氧血红蛋白体积(DEOXHB)和氧饱和度(Sto2)。物理疗法的受试者是健康的受试者,没有咀嚼系统的肌肉疼痛病史,而夹板疗法的受试者是患有咀嚼性肌肉症状的TMD患者,这些患者使用了使用稳定夹板。应用的物理疗法是20平方米热包和30平方米的肌监测器。 DEOXHB在热包应用之前和之后的值之间没有显着差异。结果表明,人咬肌的血液流量可能会受热包的影响,并且热包疗法的效果是增加区域血液的体积,并且为有氧能量代谢创造了有利条件。2)2)2)在没有较大的血液中,在米诺循环中,在不重新启动的情况下,在较高的seprint中,在均值范围内均不明显的值。握紧夹板的THB明显大于没有夹板的THB。结果表明,在短期内佩戴稳定夹板可以影响咬肌的血流。但是,长期使用夹板的影响仍然未知。需要进一步研究穿着夹板中咀嚼肌的血液流量变化的进一步研究。
