19 Triceps Brachii Release
This module teaches the release of the Triceps, a powerful extensor muscle of the arm. Chronic spasm here can contribute to posterior arm pain and elbow restriction.
Step 1
Understanding the Problem
The triceps brachii is the primary extensor of the elbow.
It spans:
• the posterior humerus
• and, through its long head, the scapula
When functioning normally:
👉 it allows smooth extension and controlled flexion of the elbow
When it enters spasm:
👉 it creates resistance to flexion
👉 and begins to affect both elbow and shoulder mechanics
This is not just a local muscle problem.
It is a mechanical and neurological restriction.
Step 2
The Clinical Problem
A client arrives complaining of pain along the back of the upper arm or deep discomfort near the elbow.
They may notice that bending the elbow becomes painful, and extending the arm feels weak or difficult.
Even simple activities such as pushing open a door, rising from a chair, or lifting objects may become uncomfortable.
Despite treatment of the elbow or forearm, the symptoms often persist.
In many cases the source lies within the triceps muscle, the primary muscle responsible for extending the elbow.
The triceps consists of three heads, including the long head, which originates from the scapula and crosses the shoulder joint before attaching to the elbow.
Because of this attachment pattern, spasm in the triceps can affect both elbow movement and shoulder mechanics.
When the triceps enters spasm, the muscle remains locked in contraction and creates persistent tension along the posterior arm.
Clients may experience:
• deep pain along the back of the arm
• difficulty bending the elbow
• weakness or pain when extending the arm
• discomfort during shoulder abduction
The triceps region is also closely associated with important neural pathways.
The radial nerve travels along the posterior arm in close relationship to the triceps, and portions of the muscle form a protective sheath around this nerve.
When the triceps becomes chronically contracted, it can irritate or compress the radial nerve, particularly when the elbow is flexed. Because elbow flexion stretches the radial nerve, clients may feel sharp discomfort when bending the arm.
The long head of the triceps also participates in the anatomical region sometimes described as the axillary nerve passage, where the teres minor, teres major, and triceps long head surround the route of the axillary nerve as it travels toward the deltoid.
Spasm within this muscular corridor can contribute to irritation of the axillary nerve and produce discomfort in the shoulder region as well.
For these reasons, triceps spasm can interfere with several essential movements of the arm.
Clients often find that both bending and extending the elbow become painful, making routine daily tasks surprisingly difficult.
Releasing the triceps restores normal motion of the elbow, reduces pressure on nearby nerves, and allows the arm to regain its normal strength and range of movement.
Step 3
Why This Happens
The radial nerve travels through radial noose (space between tendons of Triceps, Teres Major and Teres Minor) before entering the radial nerve sheath within the lateral head of the triceps. This is where it passes through the back of the upper arm before passing underneath the brachioradialis muscle and entering the elbow and posterior forearm.
​
When the triceps enters spasm:
👉 it compresses the radial nerve along its pathway through its own sheath in the triceps.
​
This creates:
• localized pain in the triceps brachii
• altered signaling to the forearm and hand
• restricted flexion of the elbow
• weakness and pain while exerting force when trying to extend the elbow
​
At the same time:
The long head of the triceps attaches to the scapula.
Together with:
• teres major
• teres minor
​
it forms what we refer to as:
👉 the axillary noose
​
When these muscles are in spasm:
👉 they can compress the axillary nerve
​
Side note about the radial nerve:
• the radial nerve can also become impinged where it passes beneath the brachioradialis at the humerus bone just before the elbow where the radial nerve passes to the posterior forearm. The brachioradialis after crossing over the radial nerve heads to the other side of the forearm - the anterior forearm and inserts onto the distal end of the radius bone.
• The radial noose, the triceps brachii and the brachioradialis are all places where the radial nerve can get pinched and cause radiating pain down the back of the forearm and hand. Release them all and radial pain will be totally relieved.
​
When in spasm, the triceps brachii creates a combined effect:
👉 limited and painful elbow flexion
👉 restricted shoulder movement
👉 radial nerve compression
Step 4
Anatomy
The radial nerve travels along the posterior humerus through the triceps.
​
When the triceps enters spasm:
👉 it compresses the radial nerve along its pathway
​
This creates:
• localized pain in the triceps
• altered signaling to the forearm and hand
​
At the same time:
The long head of the triceps attaches to the scapula.
​
Together with:
• teres major
• teres minor
​
it forms what we refer to as:
👉 the axillary noose
​
When these muscles are in spasm:
👉 they can compress the axillary nerve
​
This affects:
• the deltoid
• shoulder abduction
​
This creates a combined effect:
👉 painful elbow flexion
👉 restricted shoulder movement
Step 5
Palpation & Tissue Assessment
Palpation is performed along the posterior upper arm.
Cross-Fiber Assessment
Move across the fibers of:
• long head
• lateral head
• medial head (deeper)
Spasm feels like:
• dense, rope-like bands
• resistance to compression
• clearly defined fibers
Healthy tissue:
• soft
• broad
• difficult to isolate
Functional Confirmation
• is elbow flexion restricted?
• is there pain when bending the arm?
• does the posterior arm feel tight and guarded?
👉 the triceps is involved
Step 6
Neurological Consequences
Radial n.
When the triceps brachii enters spasm, it can compress the radial nerve pathway through the upper arm.
The radial nerve is the nerve that supplies the posterior forearm and hand. When its compressed it will cause spasm of the extensor digitorum muscle. This is the muscle that extends the fingers, so compression of the radial nerve anywhere can lock the posterior forearm. This causes pain on the back of the forearm, hand and fingers, especially when trying to flex the fingers.
​
This produces symptoms such as:
• Loss of ability to freely flex the elbow, wrist and fingers
• Pain along the posterior upper arm, elbow, forearm, wrist, hand and fingers, especially during flexion
• Radiating along the same posterior route
• Weakness in all of these muscles resulting in difficulty adducting the shoulder, and extending the elbow, wrist, hand and fingers
​
Triceps spasm can be a real pain in the back of the arm, making it difficult to push off of a seat when trying to stand up, or perform movements that would normally be easy with the hand and arms. Understanding these neurological relationships allows the practitioner to identify the correct release protocol.
Step 7
Technique Demonstration
Pay attention to:
• practitioner stance and grounding
• hand placement along the posterior arm
• direction of pressure into the triceps
• coordination with arm positioning
• the Yang–Yin release cycle
​
Observe:
• slow, controlled compression
• no excessive force
• the moment the tissue softens
​
👉 this is the release point

Practice Assignment
Clinical Skill Development
Set up:
• client supine, prone or side-lying
• upper arm and shoulder should be totally accessable
​
Focus on:
• use your inside (hand that is closer to the clients body) hand to hold the forearm and wrist so it can guide it into flexion of the elbow
• isolating each head of the triceps with cross-fiber palpation using the other hand to locate its tightest fibers and tightest pointss iwthin those fibers- these are release points.
•while slowly flexing the elbow as far as possible with the inside hand, the triceps will reach its maximum ability to stretch.
• in this position the hand that has been palpating to find the tightest point needs to really sinki into the tightest one it finds, increasing pressure until it feels like a guitar string that cannot be bent anymore. Muscles are tough, so use firm pressure. The peak of pressure is the end of the yang phase. From here, wait for a sense of softening to occur after 15 seconds or so. When this happens, slowly make it feel like your pressure is not only not building, but almost creating a feeling of falling away, but here is the paradodx. Y0ou need to not give up any ground while very lightly making it feel like you are backing off. Creating these two sensations at the same time triggers the Yin phase. During the yin phase, the muscle fibers you are pressing on change in texture from a solid to liquid.
​
Remember:
👉 repeat this process until all three heads of the triceps brachi release
​
Practice until:
• full elbow extension has regained full mobility
• the triceps brachii feels pain free
• you feel that your body mechanics and hand positions are comfortable and properly aligned
Step 10
