The Babinski reflex is perhaps the best-known reflex. It is sometimes used during the assessment of neurological damage after accidents that may result in lower extremity dysfunction. It is described as a "slow, majestic elevation of the big toe" after stimulation of the outer edge of the foot.

In babies, this reflex is very useful and is activated in many situations:

• It helps the baby propel itself when crawling or walking on all fours
• It prepares the baby to stand up and strengthen the arch of the foot
• It participates in the implementation of the gravity reflex
• ...

The Babinski stays active for a very long time. On average, it disappears around the age of two, but it is not uncommon to find it active for up to three years.

Observation

Run your finger (or a pen) along the outer edge of your baby's foot. If there is little or no reaction, the Babinski is properly integrated. Conversely, if the foot moves away from the stimulation or your child has an irresistible urge to rub the foot after the test, the reflex is still active and should be integrated.

Consequences of non-integration

People who do not have a properly integrated Babinski reflex tend to walk on the inner or outer edge of the foot. This tendency is sometimes visible in shoes that are worn much more on one side than the other. This edge walking caused by the Babinski reflex can lead to muscle pain, especially in the hips.

Integration exercises

Walking barefoot in the sand and letting your toes sink into the sand will help to integrate the Babinski reflex.

It is also possible to wedge a ball between your feet and gently crush it, controlling its force, for the time of an exhalation. After a few repetitions, it is advisable to do the opposite. Wedge a rubber band around your feet and gently pull them apart.
