Erector spinae anticipatory postural adjustment latency

downin humans1

1 study

  1. Startling acoustic sound decreases erector spinae anticipatory postural adjustment latency in humans.

    “APAs of the ES were accelerated in older participants to a similar degree as in younger participants during the startling cue.”
