At the back of the shoulder, the long head of the triceps brachii, the teres major and the teres minor intersect around a small triangular space. The axillary nerve passes through that space, and the radial nerve passes just below it. Releasology calls this the axillary-radial noose. When these three muscles tighten from pushing, pressing, carrying or holding the arm extended, the noose closes and pinches both nerves at once. This is one of the most likely places the radial nerve is compressed, and a pinched radial nerve throws every muscle downstream into spasm: the triceps itself, then the forearm extensors, the wrist and the hand. Bending the elbow becomes painful and limited, the back of the arm aches, and the forearm and hand lose signal. Releasology releases all three muscles of the noose, freeing both nerves at the source, and then the chain below them lets go.

What this release relieves

• Pain along the back of the upper arm. The deep ache behind the arm is the triceps in spasm; it eases as it releases.
• Painful, limited elbow bending. A triceps in spasm resists being lengthened, so every elbow flexion pulls against it. Released, the elbow bends freely.
• Radial nerve compression: spasm and pain down the forearm and hand. When the noose pinches the radial nerve, the triceps, the forearm extensors and the muscles of the wrist and hand all spasm downstream. Release the noose and the whole chain releases.
• Axillary nerve compression: shoulder pain and restricted shoulder movement. The axillary nerve passes straight through the noose; compressed, the deltoid and the back of the shoulder ache and weaken. Freed, the shoulder moves again.
• Deep discomfort at the elbow and weak arm extension. The triceps attaches at the point of the elbow; spasm keeps that attachment sore, and a muscle in spasm tests weak until it is released.
• Tennis elbow that keeps returning. Forearm extensors that will not stay released are often being driven by a radial nerve pinched at the noose above them. Release the source and the elbow finally settles.

El tríceps braquial es el principal extensor del codo.

Abarca:

• el húmero posterior

• y, a través de su larga cabeza, la escápula

Cuando funciona normalmente:

👉 Permite una extensión suave y una flexión controlada del codo.

Cuando entra en espasmo:

👉 crea resistencia a la flexión

👉 y comienza a afectar la mecánica tanto del codo como del hombro.

No se trata simplemente de un problema muscular localizado.

Se trata de una restricción mecánica y neurológica.

Frequently asked questions

What is the axillary-radial noose?

The triangular space at the back of the shoulder formed by the long head of the triceps, the teres major and the teres minor. The axillary nerve passes through it and the radial nerve passes just beneath it. When the three muscles tighten, the noose closes on both nerves. Releasing all three opens it.

Why does my elbow hurt when I bend it, not when I straighten it?

Because the muscle in spasm is the triceps, which has to lengthen for the elbow to bend. Straightening shortens it and feels fine; bending stretches it and hurts. Release the spasm and bending stops hurting.

My forearm and hand are the problem. Why work on the back of my shoulder?

Because the radial nerve that runs the forearm extensors and the hand is most likely pinched at the noose, near the shoulder. Everything downstream of a pinched nerve goes into spasm. Release the noose and the forearm and hand let go; work on the forearm alone keeps coming back.
