The primary objectives of the proposed two studies are to ascertain the: a) interrelationships between sensorimotor functions and masticatory performance, food selection and patient satisfaction in dentate persons and denture wearers; and b) influence of an EMG biofeedback program to establish a chewing pattern of similar bilateral muscle activity in denture wearers and the effects of this change on their masticatory performance, food selection, and patient satisfaction. In Study 1, 140 denture patients with clinically acceptable dentures will be divided into two equal groups of low and high masticatory performance. A control group of 70 dentate persons with 28 or more teeth will provide the reference values and estimates of variability for assessing alterations of sensory, motor and perceptual functions, masticatory performance and other measures. Medical and dental histories, clinical orofacial and denture evaluations and subjective ratings of food preference and satisfaction will be collected. Objective measures of masticatory performance, masseter EMG activity, bite force, tactile and two-point discrimination thresholds, stereognostic ability, salivary secretion rates and oral clearance ability will be made. The comparisons between dentate subjects and denture wearers with high and low performance will be made to assess any alterations in oral sensory, motor and perceptual functions in denture wearers and their impact on masticatory performance, patient satisfaction and food selection. In Study II, the effects of an EMG biofeedback program, to produce a bilateral pattern of chewing effort on masticatory efficiency will be evaluated in 90 denture wearers with low masticatory performance. Patients will be randomized into a control group of 45 or an experimental biofeedback group of 45 persons. Bilateral masseter EMG activity will be recorded while the patients perform bite force and preferred side and swallowing threshold masticatory tests with peanuts. The experimental group will then participate in bi-weekly EMG biofeedback sessions for eight weeks. The biofeedback program will be designed to alter the chewing pattern so that patients learn to apply equal masseter muscle activity bilaterally. The control group will follow the same schedule of bi-weekly sessions for eight weeks. They will be given instructions to chew bilaterally and will not receive the biofeedback. The performance tests and subjective evaluations will be repeated after four weeks of training, at the end of the eight week training period and thereafter at three months.

拟议的两项研究的主要目标是确定 ：a）感觉运动功能与咀嚼性之间的相互关系 牙齿人的表现，食物选择和患者满意度 和牙齿佩戴者； b）EMG生物反馈程序对 建立在双侧肌肉活动中的咀嚼模式 义齿佩戴者及其对咀嚼性的影响 表现，食物选择和患者满意度。 在研究1中，有140名具有临床上可接受义齿的义齿患者 将分为两组低咀嚼性和高咀嚼性 表现。 一个由70个牙齿或更多牙齿的对照组组成 将提供参考值和可变性的估计值 评估感觉，运动和感知功能的改变， 咀嚼性能和其他措施。 医疗和牙科 历史，临床口面和义齿评估以及主观 将收集食物偏好和满意度的评分。 客观的 咀嚼性能，咬合EMG活性，咬合力的度量， 触觉和两点歧视阈值，立体认知能力， 将提高唾液分泌率和口服清除能力。 这 比较高和高的齿状受试者和义齿佩戴者 低性能将评估口服感觉的任何改变， 义齿佩戴者的运动和感知功能及其对 咀嚼性表现，患者满意度和食物选择。 在研究II中，EMG生物反馈计划的影响 咀嚼效率的咀嚼努力的双边模式将是 在90个牙齿佩戴者中进行评估，具有低咀嚼性的性能。 患者将被随机分为45或实验的对照组 45人的生物反馈小组。 双边咬合EMG活性将是 在患者执行咬合力和首选方面记录，并且 用花生进行吞咽阈值咀嚼测试。 实验 然后，小组将参加每两周一次的EMG生物反馈会话 八周。 生物反馈程序将旨在改变 咀嚼模式，使患者学会施加相等的咬肌 双侧活动。 对照组将遵循相同的时间表 每两周一次的会议八周。 他们将得到指示 双侧咀嚼，不会收到生物反馈。 表演 四个星期后，将重复测试和主观评估 培训，在八周的培训期结束时，此后 三个月。
