THE PREVALENCE OF SYMPTOMS OF T M DISORDERS

我们对TM疾病的患病率的了解仍然存在差距， 北美人口。 本提案描述了一项关于 与这些疾病相关的体征和症状的患病率 加拿大社区。 它旨在测试方法和工具的各个方面， 用于更全面的研究并提供初步数据， 这是研究计划所必需的。 具体来说，它将确定 对电话访谈请求的响应率，测试可靠性 调查问卷和审查过程，确定答复率， 邀请有症状和无症状患者参加临床检查 并允许在访谈和临床期间收集信息 检查比较。 将采用随机数字拨号技术来识别随机 对1000名18岁及以上的人进行了抽样调查， 多伦多。 这些人将接受采访， 关于疼痛、关节音和 下颌运动受限，其严重程度和功能 后果 关于各种相关症状的问题也将 问道 为了检验问卷的可靠性， 被问到的人的子样本将被召回，面试 再读。 400名受访者将被要求参加一个临床试验， 检查，从有症状和有症状的患者中随机抽取相同数量的患者， 无症状人群。 考试将包括一个历史， 观察下颌运动和关节音， 关节和肌肉的咀嚼和测量 上下颌关系 10%的随机子样本将 重新检查以检查检查程序的可靠性。 长期目标是进行纵向流行病学研究， 记录TM疾病体征和症状的自然史， 调查各种一般和地方的相对影响 该病发病和病程的病因因素以及 寻求治疗。

There remain gaps in our knowledge of the prevalence of TM disorders in the North American population. This proposal describes a pilot study of the prevalence of signs and symptoms associated with these disorders in a Canadian community. It aims to test aspects of the methods and instruments to be used in a more comprehensive study and to provide preliminary data necessary for the planning of the study. Specifically, it will ascertain response rates to requests for telephone interviews, test the reliability of the questionnaire and examination process, determine response rates to invitation for clinical examination among symptomatic and non-symptomatic groups and allow information collected at interview and during the clinical examination to be compared. A random digit dialing technique will be employed to identify a random sample of 1000 persons aged 18 years and over living in the City of Toronto. These will be interviewed using a schedule designed to elicit information on the difinitional symptoms of pain, joint sounds and limitations in mandibular movement, their severity and functional consequences. Questions on a variety of associated symptoms will also be asked. In order to test the reliability of the questionnaire, a 10% random sub-sample of those questioned will be recalled and the interview readministered. Four hundred of those interviewed will be asked to take part in a clinical examination, equal numbers being drawn at random from symptomatic and non-symptomatic groups. The examination will consist of a history, observation of mandibular movement and joint sounds, palpation of the joints and muscles of mastication and measurement of the mandibular-maxillary relationship. A 10% random sub-sample will be re-examined to check the reliability of the examination procedure. The long term aim is to undertake a longitudinal epidemiological study to document the natural history of signs and symptoms of TM disorders and to investigate the relative influence of a variety of general and local aetiological factors on the onset and course of the disorder and the seeking of treatment.
