Variations in spinal motoneuronal excitability were assessed during wakefulness and non-REM sleep in hyperkinetic and normal children by determining the recovery cycle of the H-reflex following a conditioning stimulus. Reflex facilitation which generally occurs 100-300 msec after a conditioning stimulus was markedly reduced during sleep in both groups and during wakefulness as well in hyperkinetic subjects. Among possible mechanisms which might underlie the observed reductions in facilitation, emphasis is placed on decreased central excitability resulting from depressed fusimotor activity.
通过确定条件刺激后H反射的恢复周期，评估了运动亢进儿童和正常儿童在清醒和非快速眼动睡眠期间脊髓运动神经元兴奋性的变化。在两组睡眠期间以及运动亢进受试者清醒时，通常在条件刺激后100 - 300毫秒出现的反射易化明显降低。在可能导致观察到的易化降低的潜在机制中，重点强调了由于梭内肌运动活动降低导致的中枢兴奋性降低。
