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.

拟议两项研究的主要目标是确定 a) 感觉运动功能和咀嚼功能之间的相互关系 有齿患者的表现、食物选择和患者满意度 和假牙佩戴者； b) 肌电图生物反馈计划的影响 建立相似双侧肌肉活动的咀嚼模式 假牙佩戴者以及这种变化对其咀嚼功能的影响 表现、食物选择和患者满意度。 在研究 1 中，140 名假牙患者佩戴临床可接受的假牙 将被分为低咀嚼力组和高咀嚼力组 表现。 对照组由 70 名有 28 颗或更多牙齿的有齿人组成 将提供参考值和变异性估计 评估感觉、运动和知觉功能的改变， 咀嚼性能和其他措施。 医疗和牙科 病史、临床口面和假牙评估以及主观评估 将收集食物偏好和满意度的评分。 客观的 咀嚼性能、咬肌肌电图活动、咬合力的测量， 触觉和两点辨别阈值、立体认知能力、 将进行唾液分泌率和口腔清除能力。 这 有齿受试者和假牙佩戴者之间的比较 将进行低绩效评估口腔感觉的任何改变， 假牙佩戴者的运动和知觉功能及其对 咀嚼性能、患者满意度和食物选择。 在研究 II 中，肌电图生物反馈程序的效果，产生 咀嚼努力的双边模式对咀嚼效率的影响将是 对 90 名咀嚼能力低下的假牙佩戴者进行了评估。 患者将被随机分为 45 人的对照组或实验组 生物反馈组45人。 双侧咬肌肌电图活动将 记录患者执行咬合力和首选一侧以及 花生吞咽阈咀嚼测试。 实验的 然后小组将参加每两周一次的肌电图生物反馈课程 八周。 生物反馈计划将旨在改变 咀嚼模式，使患者学会使用均匀的咬肌 双边活动。 对照组将遵循相同的时间表 每两周一次，为期八周。 他们将收到指示 双侧咀嚼，不会收到生物反馈。 性能 测试和主观评估将在四个星期后重复 培训，在八周培训期结束时以及此后 三个月。
