Masticatory Function in the Rehabilitation of the Cerebral Apoplexy Patient

在香川县的康复医院，对脑卒中患者进行了面对面调查。研究对象为21名正在接受日间服务的居家老人、10名有吞咽障碍的住院病人和46名无吞咽障碍的住院病人。调查项目为口腔及进食功能主观症状、口腔（牙齿、牙龈、舌）、口腔周径（唇、颊、颞下颌关节）、义齿、吞咽功能、唾液、咀嚼能力。从研究对象中选取了28例住院患者和14例日间门诊患者，均采用天然牙或义齿进行后牙咬合支持。比较两组患者唾液量、唾液缓冲能力、唾液中念珠菌数、咬合力、咀嚼效率。结果表明，住院病人组的唾液量和唾液缓冲能力有低于日间服务病人组的趋势。两组唾液中念珠菌的数量也比一般老年人多得多。唾液量的多少与进食能力等级和膳食形式有一定的相关性。住院患者组的咬合力和咀嚼效率低于日间服务患者组。但个体差异较大，有必要寻找影响因素。通过调查，掌握了康复医院脑卒中患者的咀嚼功能，并指出了影响咀嚼功能的因素。

In the rehabilitation hospital in Kagawa Pref., an encounter investigation of the cerebral apoplexy patient was carried out. The research objects were 21 staying home old people who were receiving day service, 10 hospitalized patients with dysphagia and 46 hospitalized patients without dysphagia. The survey item was subjective symptom on oral cavity and eating function, oral cavity (tooth, gums, tongue), oral cavity circumference (lip, cheek, temporomandibular joint), denture, swallow function, saliva, chewing ability. From the research object, the patient (28 hospitalized patients and 14 day service patients) with the occlusal support of posterior teeth by natural teeth or denture were chosen. Between two groups, the following were compared : Saliva quantity, buffering capacity of saliva, number of candida in the saliva, biting force, masticatory efficiency. As the result, saliva quantity and buffering capacity of saliva of the hospitalized patient group tended to be lower than that of day service patient group. The number of candida in the saliva on both groups was also very more abounding than the general old people. The quantity of the saliva tended to correlate with grade of eating ability and meal form. The hospitalized patient group showed the tendency which biting force and masticatory efficiency were lower than that of day service patient group. However, the individual difference was big, and it seemed to be necessary to search the influencial factor. From this investigation, chewing function of the cerebral apoplexy patients in the rehabilitation hospital was grasped and the influencial factor on it was indicated.
