⚡Could restricted tongue mobility really affect posture, breathing, and even cause numbness in the arms? 🤔👉 Let’s learn from this case study.
Thoracic Outlet Syndrome (TOS) occurs when nerves or blood vessels that pass from the neck into the arms become compressed — often between the collarbone and the first rib. This can lead to tingling, numbness, weakness, or even pain in the arms and shoulders.
Now here’s where it gets interesting. 👇
In patients with hypermobility, the connective tissue is looser and less supportive, which can lead to forward head posture and increased tension through the neck and shoulders.
A tongue-tie adds another layer to that tension. It’s a condition where a band of connective tissue under the tongue restricts its mobility and connects tightly to the floor of the mouth. That restriction can extend through the fascia of the neck and even the diaphragm, influencing posture, breathing, and overall body alignment.
When that restriction is released, the fascia can relax, the head and neck can come back, and compression patterns in the thoracic outlet often improve.
That’s why some patients notice immediate changes in posture, breathing, and arm symptoms after a tongue-tie release.
Many people ask me about the relationship between tongue-tie and hypermobility. The truth is, patients with hypermobility are more sensitive to restrictions. Their connective tissue is already loose, so a tongue-tie stands out more — and releasing it can make a profound difference.
✨ A small change in one area can have a big impact throughout the body.
Have you ever seen something like this in yourself or your patients?
