A light stroke along the lower back, and the baby curls like a comma. Here is what this reflex prepares, and why its persistence comes up so often in the stories of children who can't sit still.
Hello to you, movement professional,
The spinal Galant reflex is one of the most talked-about whenever the topic turns to children who fidget, who can't stand clothing tags, or who wet the bed. It's also a reflex that attracts plenty of shortcuts. So let's lay out clearly what it is, what it prepares, and stay honest about what we can really pin on it.
The Galant is a primitive reflex, an automatic motor response triggered by a precise tactile stimulus. When you stroke the skin along one side of the spine, in the lumbar region, the baby lying on its belly curves the trunk toward that side, as if folding toward the finger touching it. It's a lateral, asymmetric reflex, driven by the lower levels of the nervous system rather than by will.
It carries the name of the neurologist who described it, and it belongs to the list of reflexes clinicians check to gauge the maturation of a newborn's nervous system. Its response, a lateral flexion of the trunk, already tells you what it's for: it works the sideways mobility of the pelvis and the spine. What's left is to understand why nature wired this in.
The Galant appears early in pregnancy, and it's credited with two main roles. During life in the womb and at the moment of birth, these alternating movements of the pelvis from one side to the other help the baby position itself and move forward, a kind of primitive crawling. After birth, it helps kick-start trunk mobility, the ability to separate the upper and lower body that will later serve crawling, then walking.
Like all primitive reflexes, it isn't meant to stay. It normally integrates in the first months, most often between three and nine months depending on the source, as voluntary control of the trunk comes online. And because it fires when you touch the back, it's easily confused with a neighbor.
The mix-up is common, because both reflexes respond to stimulation of the back. The difference is clear, though. The Galant responds to a lateral stroke, along one side of the lumbar spine, and bends the trunk to that side: it's lateral and asymmetric. The Perez reflex responds to stimulation along the axis of the spine, from bottom to top, and extends the whole body: it's axial and symmetric.
Holding on to this distinction means aiming at the right sensory input when you read a child. One speaks to the lateral mobility of the trunk, the other to straightening the axis. Which brings us to the awkward question: what happens when the Galant doesn't fade?
This is where you have to be useful without overselling. In the field, a persistent Galant is linked to several observations that come up often: a child who can't sit still, constantly bothered by the waistband of their pants, the back of the chair, or the fabric of a t-shirt, as if their back were endlessly tickled. There are also reported links with restlessness, attention difficulties, and nighttime bedwetting, because, according to some clinical observations, stimulation of the lower back may be tied, in the very young child, to emptying the bladder.
The key word, once again, is 'linked.' These connections come largely from practitioners' observations, not solid studies, and at best they're correlations. In the same way, the idea that a cesarean or instrument-assisted birth would prevent the reflex from integrating is a hypothesis some put forward, not a proven fact. The reflex is an indicator, not a culprit. No serious practitioner will tell you that integrating the Galant cures an attention disorder or bedwetting. What we can say, cautiously, is that a back constantly stirred by a reflex that was never properly put away means less attention left for everything else.
Our approach to the Galant is the same as for every reflex. We don't try to 'integrate' it with a recipe applied blindly. We use it as an indicator: a lingering Galant points to the tactile sensitivity of the back and the mobility of the trunk, and that's the input we rework, through deep contact, floor-based movement, and the gradual dissociation of the trunk. Integration becomes a consequence, never a promise on display.
This is the grid that ties each reflex to a sensory system and to posture, the one that separates rigorous reading from promises of instant cures. The Galant is neither a curiosity nor the cause of all a child's troubles. It's a window into how their back got wired, and into what's left to recalibrate.
It's a primitive reflex: a light stroke along one side of the lumbar spine makes the baby's trunk curve toward that side. It contributes to trunk mobility and to primitive crawling before and after birth.
It most often fades between three and nine months, as voluntary control of the trunk takes hold. These markers vary from one source to another, and an assessment by a trained professional is still needed to draw conclusions.
Links are reported between its persistence and bedwetting or restlessness, but these are associations observed by practitioners, not proof of cause. Integrating it is not a treatment for these difficulties.
The Galant is lateral: it bends the trunk to one side after a lateral stroke. The Perez is axial: it extends the whole body after stimulation along the spine, from bottom to top.
You slide a finger along one side of the lumbar spine, with the baby lying on its belly, and observe how the trunk curves and how symmetric it is. Interpretation is up to a trained professional.
