目的：研究口腔精细运动咬合任务中振动刺激对咬肌的影响。方法：16 名健康个体（年龄：24.5 +/- 2.4 岁）参与实验 I，实验中要求参与者用前牙“握住并劈开”半个放在力传感器上的烤花生。参与者进行了十个系列，其中十次试验“保持和分开”行为任务，同时每个交替系列对咬肌施加振动刺激。此外，14 名参与者（年龄：25.2 +/- 4.8 岁）参与了实验 II，在此期间，他们在基线、调整后的基线（无振动和有振动以及有或没有视觉反馈）下执行了一系列行为任务。测量了保持力和分裂力，以及保持力和持续时间的变化以及分裂过程中的力速率。结果：研究结果表明，保持力的大小 (P = 0.002)、分裂过程中的力速率 (P
Purpose: To investigated the effect of vibratory stimulus on masseter muscles during oral fine motor biting tasks.Methods: Sixteen healthy individuals (age: 24.5 +/- 2.4 years) participated in experiment I during which the participants were asked to "hold and split" half a roasted peanut placed on a force transducer with their front teeth. The participant performed ten series with ten trials of the "hold and split" behavioral task while vibratory stimulus was applied on the masseter muscle every alternate series. Further, fourteen participants participated (age: 25.2 +/- 4.8 years) in experiment II during which they performed a series each of the behavioral task at baseline, an adjusted baseline without and with vibration as well as with and without visual feedback. Hold and split forces along with the variability of hold force and duration and force rate during the split were measured.Results: The results of the study showed an increase in the magnitude of the hold force (P = 0.002), force rate during the split (P
