一些学者认为,关节病早期特点是出现关节杂音,当时疾病还未出现明显临床症状及X线变化。(?)-根据其频率特点评价关节杂音,发现在关节病时测得低振幅波及伴有大的长波形,而关节炎时出现一些单个的高振幅尖波。但目前尚没有关于正常及有病变时关节杂音情况的报道。材料和方法测定10名无关节疾病(对照组),5名急性关节炎,6名慢性关节炎和20名颞颌关节病患者的关节杂音。与可以听到关节声音的听诊器不同,
Some scholars believe that the early characteristics of joint disease is the emergence of joint noise, when the disease has not yet obvious clinical symptoms and X-ray changes. (?) - To evaluate joint noise based on its frequency characteristics and to find low-amplitude waves with large long waves at arthropathy and some single high-amplitude sharp waves at arthritis. However, there are no reports of joint noise in normal and diseased cases. MATERIALS AND METHODS Joint noise was measured in 10 non-joint disease (control group), 5 acute arthritis, 6 chronic arthritis and 20 temporomandibular joint patients. Unlike stethoscopes that hear articulation,
