1) Development of 2D motion analyze system for videofluorography.We made a 2D motion analyze system for videofluorography using personal computer to analyze the hyoid and jaw movement during mastication and swallowing.2) Analyze of normal swallowingDuring the mastication, hyoid movement on X-axis had high relationship with lower jaw movement on X axis (r=0.81), but hyoid and lower jaw movement on Y-axis had lower relation (r=0.52)At the initiation of pharyngeal phase, the upward and forward movement was remarkable, especially on X-axis. At that time, the lower jaw attached upper jaw and the jaw movement stopped.The swallowing that has mastication showed that the bolus penetrate to the pharyngeal area before pharyngeal swallow (pharyngeal penetration) in about 80 %.The swallowing of mixed material liquid and solid with mastication showed the pharyngeal penetration in 100 %.3) Analyze of dysphagia of CVA.In non aspiration group the swallowing of mixed material showed the pharyngeal penetration in 100 %.In aspiration group the swallowing of mixed material showed the pharyngeal penetration in about 60 %.

1)2）正常吞咽分析在咀嚼运动中，舌骨在X轴方向上的运动与下颌在X轴方向上的运动有很大的相关性（r=0.81），而舌骨与下颌运动在Y轴上的相关性较低（r=0.52）。在当时，有咀嚼的吞咽表现为食团在咽部吞咽前先进入咽部（咽部穿透率为80%），咀嚼混合物液、固吞咽时咽部穿透率为100%。CVA吞咽困难分析：非误吸组吞咽混合物100%表现为咽部穿透，误吸组吞咽混合物60%表现为咽部穿透。
