Startle (Moro) Reflex

What is the Startle (Moro) Reflex?

The Startle Reflex is present at birth. It’s an automatic movement in response to sudden sounds, touch, or movement.


This reflex helps Baby take their first breath at birth, releases adrenaline to support the birthing process, and begins the instinctive responses that keep Baby safe.

The Startle Reflex triggers both physical and auditory reactions—Baby’s arms and legs extend, and they often cry. This alerting cry signals to the caregiver that Baby needs comfort or protection.

Signs of a Retained Startle (Moro) Reflex

A retained or overactive Startle Reflex may show up in older children or adults as:

  • Anxiety or emotional regulation challenges

  • Motion sickness in cars or amusement rides

  • Balance or coordination issues

  • Hypersensitivity to sound, light, or touch

  • Startling or waking easily

  • Withdrawn, timid, or shy behavior

  • Discomfort rolling onto the back

An overactive Startle Reflex may also appear as significant startles, frequent crying, fussiness, or needing to be held constantly.

How Chiropractic Care Can Help

Dr. Melanie Beingessner, Dr. Laurence Dion, Dr. Leah Robinson from Blessingways Family Wellness in Airdrie and North Calgary, AB

At Blessingways Family Wellness in Airdrie and North Calgary, our chiropractors—Dr. Melanie Beingessner, Dr. Laurence Dion, and Dr. Leah Robinson—help families support healthy brain and body development through gentle, movement-based chiropractic care.

When retained primitive reflexes are suspected, we:

  1. Perform a thorough chiropractic and neurological examination.

  2. Review a detailed intake form to identify which reflexes may be active.

  3. Create a personalized care plan that includes gentle chiropractic adjustments and home-based movement activities.

  4. Recommend daily exercises to help the nervous system learn new, more coordinated patterns.

  5. Re-evaluate progress regularly to monitor changes and refine care.

Every nervous system is unique. While many people respond well to chiropractic adjustments and home movement activities, progress depends on each individual’s ability to adapt and integrate new information.
