伤害性屈曲反射在收缩期受到抑制;这种抑制可能是由于压力感受器刺激增加。其他脊髓反射在心动周期中是否也受到类似的调制,这一点还有待确定。也有证据表明,拉伸和肌腱反射是促进增加唤醒。本研究探讨了心动周期时相和觉醒对肌肉牵张反射成分M1、M2和M3的影响。在休息、数字重复和心算过程中,在心动周期的六个时间间隔内,腿部肌肉引起牵拉反射。心算引起心血管觉醒增加,促进M1和M2相比,休息和数字重复。牵张反射不随心动周期时相变化。虽然牵张反射易受唤醒的影响,但在整个心动周期中,自然的压力感受器介导的调制可能对伤害性感受具有特异性。
The nociceptive flexion reflex is inhibited during systole; this inhibition may be due to increased baroreceptor stimulation. It is yet to be determined whether other spinal reflexes are similarly modulated across the cardiac cycle. There is also evidence that stretch and tendon reflexes are facilitated by increased arousal. This study investigated the effects of phase of the cardiac cycle and arousal on the muscle stretch reflex components M1, M2, and M3. Stretch reflexes were elicited in leg muscles at six intervals across the cardiac cycle during rest, number repetition, and mental arithmetic. Mental arithmetic provoked increased cardiovascular arousal and facilitated both M1 and M2 compared to rest and number repetition. The stretch reflex did not vary with the phase of the cardiac cycle. While the stretch reflex is susceptible to arousal, natural baroreceptor‐mediated modulation across the cardiac cycle may be specific to nociception.
