类似于具有非常短的反应时间的扫视眼球运动实验中的差距范例，我们假设在实验条件下，使用类似的间隙范例，通过视觉提示引导口咽吞咽运动的启动被鼓励。方法在计算机显示器上顺序地向11名健康人提供指示在口中保持药丸的红色视觉提示和指示吞咽药丸的蓝色视觉提示。参与者这些线索之间的差距周期从0到800 ms不等。吞咽动力学和运动学记录使用表面肌电图和激光位移sensors.ResultsIn相比，无间隙paradigm，延迟从肌肉活动的发病开始运动显着降低了100-（p< 0.01）和200-ms（p< 0.005）的间隙期。与其他间隙期间，没有显着的变化被检测到在delay.ConclusionsInitiation的视觉引导吞咽增强间隙范例100-200毫秒。以类似的方式增强腕关节屈曲。因此，差距效应可能是一种普遍的警告效应。
ObjectiveAnalogous to the gap paradigm in experiments for saccadic eye movements with very short reaction times, we hypothesized that the initiation of oropharyngeal swallowing movements guided by visual cues are encouraged under experimental conditions using a similar gap paradigm.MethodsA red visual cue indicating to hold a bolus in the mouth and a blue one indicating to swallow the bolus were sequentially provided on a computer display to 11 healthy participants. The gap period between these cues varied from 0 to 800 ms. Swallowing kinetics and kinematics were recorded using surface electromyography and a laser displacement sensor, respectively.ResultsIn comparison with the no-gap paradigm, the delay from the onset of muscle activities to initiation of movement significantly decreased with a 100- (p< 0.01) and 200-ms (p< 0.005) gap period. With other gap periods, no significant change was detected in the delay.ConclusionsInitiation of visually guided swallowing was enhanced by a gap paradigm of 100–200 ms. Wrist flexion was boosted in a similar manner. Thus, the gap effect may be a generalized warning effect.SignificanceOur findings might provide insights into the contribution of the basal ganglia to volitional swallowing.
