Studies of low- and high-threshold reflex reactions evoked by dorsal root stimulation in different phases of real locomotion (swimming) in rat were performed. The pronounced facilitation of low- and high-threshold muscle responses in the period of particular muscle activity and their extensive depression in the period coupled with antagonist muscle activity were revealed. The low-threshold stimulation did not change the temporal and amplitude parameters of locomotor movements, but high-threshold one influenced the amplitude and frequency of locomotor movements. The functional significance and possible mechanisms of modulation of the influence of peripheral afferents are discussed.
对大鼠在真实运动（游泳）不同阶段由背根刺激诱发的低阈值和高阈值反射反应进行了研究。结果显示，在特定肌肉活动期间，低阈值和高阈值肌肉反应明显增强，而在与拮抗肌活动相关的时期则广泛受到抑制。低阈值刺激并未改变运动动作的时间和幅度参数，但高阈值刺激会影响运动动作的幅度和频率。文中讨论了外周传入神经影响调节的功能意义及可能机制。
