Trigger Point Compression

Classification

Element	Detail
Category	Non-Swedish — Static Pressure / Neuromuscular
Subcategory	Trigger point deactivation
FOMTRAC	PC 3.2m
Fritz method	Compression (sustained, focal)

Purpose

Deactivate myofascial trigger points by interrupting the metabolic crisis at the motor end plate
Reduce referred pain patterns associated with active trigger points
Restore normal muscle length and function by resolving the taut band

Mechanism

Trigger points are regions of sustained sarcomere contracture at dysfunctional motor end plates, creating a localized energy crisis: the contracted sarcomeres compress local capillaries, reducing blood flow and oxygen delivery, while simultaneously increasing metabolic demand. Sustained compression at 5-7/10 pain tolerance creates temporary ischemia in the already-compromised tissue. When pressure is released, reactive hyperemia floods the area with oxygenated blood, breaking the energy crisis cycle. The ischemia also stimulates local nociceptors, triggering an endorphin-mediated analgesic response. Over 30-90 seconds, the sustained input reduces motor end plate activity and allows the contracted sarcomeres to release.

Indications

Palpable taut band with a tender nodule (the defining feature of a trigger point)
Active trigger points producing referred pain (client recognizes the referral pattern as "their pain")
Latent trigger points limiting ROM or contributing to chronic dysfunction
Tension headaches from upper trapezius, SCM, or suboccipital trigger points
Myofascial pain syndrome
Low back pain with quadratus lumborum or gluteal trigger points
Rotator cuff dysfunction with infraspinatus or subscapularis trigger points

Contraindications

Acute inflammation over the treatment site
Anticoagulant therapy (modify pressure significantly; deep compression risks bruising)
Client unable to tolerate sustained pressure (use muscle approximation or indirect approaches instead)
Infection in the treatment area
Caution: over areas with superficial neurovascular structures (e.g., anterior triangle of the neck)

Effects

Immediate:

Local ischemia during compression → reactive hyperemia on release
Reduction or elimination of referred pain pattern
Decreased nodule tenderness and taut band tension
Endorphin-mediated analgesia

Cumulative (repeated sessions):

Progressive deactivation of the trigger point
Restored normal muscle length and ROM
Decreased frequency of referred pain episodes
Resolution of the taut band

Risks and Side Effects

Post-treatment soreness (24-48 hours) — common and expected; advise client in advance
Bruising if pressure is excessive or if client is on anticoagulants
Autonomic responses during treatment: nausea, sweating, lightheadedness (monitor and reduce pressure if these occur)
Aggravation if applied too aggressively or for too long
Referred pain increase during compression — this is expected (reproducing the referral pattern confirms you are on the correct point)

Expected Outcomes

Short-term (within session):

Reduced nodule sensitivity (tenderness drops from 5-7/10 to 2-3/10)
Decreased referred pain
Improved ROM in the associated muscle

Medium-term (over 3-6 sessions):

Progressive reduction in nodule size and irritability
Resolution of the referred pain pattern
Restoration of full muscle length

Execution

Step	Detail
Client position	Position that allows comfortable access to the target muscle with the muscle in a relaxed (not stretched) position
Locate the trigger point	Palpate for the taut band first, then slide along it to find the most tender nodule; confirm with the client ("Does this reproduce your familiar pain?")
Hand placement	Reinforced thumb or fingertip directly on the nodule
Action	Apply gradual, progressive pressure until the client reports 5-7/10 pain; hold at that intensity
Pressure	Moderate — enough to reach 5-7/10 on the client's pain scale (this varies by muscle depth and client sensitivity)
Duration	30-90 seconds; wait for the tissue to soften or the client to report a decrease in pain intensity
Release	Gradually release pressure; do NOT suddenly remove your thumb
Follow-up	Apply effleurage or gentle stripping to flush the area; follow with stretching of the treated muscle
Lubricant	None during compression (need grip); lubricant for follow-up effleurage

Parameters

Parameter	Range	Clinical Reasoning
Pressure	Client's 5-7/10 pain	Below 5 may be insufficient to create ischemia; above 7 triggers protective guarding that counteracts the technique
Duration	30-90 sec	Minimum time for ischemia/hyperemia cycle and motor end plate reset
Repetitions	1-3 per trigger point	Reassess after each application; stop if tenderness has significantly reduced
Total points per session	3-5 active trigger points	Treating too many in one session increases post-treatment soreness
Session frequency	1-2x/week	Allow 48-72 hours between sessions for tissue recovery

Clinical Notes

Most common error: Bouncing on and off the trigger point. Sustained, steady pressure is essential — intermittent pressure does not create the continuous ischemia needed for the reactive hyperemia response.
How to know it is working: The client reports a gradual decrease in pain intensity during the hold (e.g., "It started at 7 but now it's a 3"). You may also feel the nodule soften or the taut band release under your thumb.
When to stop: When the client reports significant pain reduction, when you feel the tissue release, or after 90 seconds (whichever comes first). If no change occurs after 90 seconds, the point may require multiple sessions.
Clinical pearl: Ask the client "Does this reproduce your familiar pain?" when you locate the nodule. If they say yes (recognition of their usual pain pattern), you have confirmed an active trigger point. If they say "That hurts but it's not my pain," it may be a latent trigger point.

Verbal Script

> "I've found a tight spot in the [muscle]. I'm going to hold sustained pressure on it — you should feel a 'good hurt,' ideally about 5 to 7 out of 10. Let me know when you feel a change or release. If it becomes too much, just say 'lighter' or raise your hand."

Distinguishing Features

Feature	Trigger Point Compression	GTO Release
Target	Hyperirritable nodule in a taut band (muscle belly)	Musculotendinous junction
Mechanism	Ischemia → reactive hyperemia; motor end plate reset	Autogenic inhibition via Ib afferents from GTO
Pressure	Moderate (5-7/10 pain)	Light (~2 lbs; minimal pain)
Pain during technique	Expected and diagnostic (referred pain reproduction)	Minimal to none
What you palpate	Nodule within a taut band	Transition zone where muscle becomes tendon
Goal	Deactivate a specific hyperirritable point	Reduce overall muscle tone

Feature	Trigger Point Compression	Pressure Point Technique
Target	Always on a taut band with a palpable nodule	Any point that produces ischemia/hyperemia — not necessarily a taut band
Diagnostic criteria	Taut band, nodule, referred pain pattern, jump sign	Pain on pressure at a specific point
Scope	Specific to myofascial trigger point pathology	Broader concept including acupressure points, tender points, motor points

Key Takeaways

Trigger point compression targets a palpable nodule within a taut band — always confirm the taut band and referred pain pattern before applying sustained pressure
Hold pressure at the client's 5-7/10 pain level for 30-90 seconds; the ischemia/hyperemia cycle requires sustained, steady compression (no bouncing)
Distinguished from GTO release by location (muscle belly vs. MTJ), pressure intensity (moderate vs. light), and mechanism (ischemia vs. spinal reflex)
Expect post-treatment soreness for 24-48 hours; treat 3-5 trigger points maximum per session
Follow compression immediately with effleurage and stretching to capitalize on the release and restore muscle length
