Questions and Answers

What is the expanded integrated hypothesis of trigger point formation?

Muscle contraction, hypoperfusion, sympathetic nervous system activity, ischemia, hypoxia, and CGRP release (correct)

Muscle contraction and hypoperfusion

Muscle contraction and sympathetic nervous system activity

Muscle contraction and ischemia

What are the primary culprits of trigger point chronicity according to the integrated hypothesis?

Elevated levels of acetylcholine (ACh) and CGRP (correct)

Sympathetic nervous system activity and CGRP release

Muscle contraction and hypoperfusion

Ischemia and hypoxia

What is the mechanical coupling theory?

A theory that proposes that muscle contraction is regulated by the conversion of chemical energy to mechanical energy

A theory that proposes that an energy crisis ensues when Ca2+ levels at the sarcoplasmic reticulum are high and ATP levels are low

A theory that proposes that thick myosin protein filaments mechanically couple and uncouple with thin actin protein filaments to produce muscular contraction

A theory that proposes that somatic dysfunction is produced and maintained through metabolic, neurochemical, and proprioceptive influences that produce structural dysfunction of the fusimotor complex (correct)

Study Notes

Clinical Guide to Positional Release Therapy

The expanded integrated hypothesis of trigger point formation includes muscle contraction, hypoperfusion, sympathetic nervous system activity, ischemia, hypoxia, and CGRP release.
Elevated levels of acetylcholine (ACh) and CGRP drive trigger point chronicity by producing and enhancing the presence of ACh, resulting in a flood of nociceptor signals at the dorsal horn.
The mechanical coupling theory proposes that somatic dysfunction is produced and maintained through metabolic, neurochemical, and proprioceptive influences that produce structural dysfunction of the fusimotor complex.
Thick myosin protein filaments mechanically couple and uncouple with thin actin protein filaments to produce muscular contraction, regulated by the conversion of chemical energy to mechanical energy.
When calcium levels are low, actin filament binding to the myosin head is blocked, impairing the ability of the actin–myosin proteins to produce a strong crossbridge connection.
An energy crisis ensues when Ca2+ levels at the sarcoplasmic reticulum are high and ATP levels are low, which may result in the recalcitrant taut band or knot observed with osteopathic lesions.
Palpation of specific tissue structures is emphasized in PRT, and practitioners should explore the entire tissue during examination to avoid missing critical dominant tender and trigger points.
PRT is a versatile and powerful tool for facilitating the resolution of somatic dysfunction, but it should not be treated as a panacea.
During the acute inflammatory process, PRT can be used to limit muscle spasm, improve blood flow, and limit the neurochemical cascade that results in the formation of osteopathic lesions.
Controlling the formation of lesions early may reduce the propensity for central sensitization, ischemia, and tissue atrophy.
During the repair phase, tissues need adequate blood flow to receive nourishment, and pain must be controlled to permit the range of motion needed for encouraging phagocytosis and fibroplasia.
For patients who do not progress through the repair phase and fall into a state of chronic inflammation, PRT can assist in freeing them from its grip by decreasing the gamma gain, interrupting the myotatic reflex, and increasing perfusion to blood-thirsty tissues.Foundational Neurophysiological Underpinnings of Somatic Dysfunction and the Implications for Positional Release Therapy
Understanding somatic dysfunction and pain is crucial for the clinical practice of positional release therapy (PRT)
Pain travels throughout the somatic system and can permeate the entire body
Direct painful therapies may not always be necessary and indirect techniques like PRT can be more appealing
Pain, either felt or caused, can activate spinal reflexes and produce tender and trigger points in unintended areas of the body
Multiple metabolic, neurochemical, and proprioceptive factors can contribute to somatic dysfunction and structural dysfunction of the fusimotor complex
Korr's proprioceptive theory laid the foundation for other theories of somatic dysfunction
Simons and colleagues' integrated hypothesis of trigger point formation highlights motor end plate dysfunction and central sensitization as primary culprits
Gerwin and colleagues' expanded model proposed additional mechanisms that may lead to the development and maintenance of trigger points
Speicher's mechanical coupling theory emphasizes how metabolic, neurochemical, and proprioceptive influences may work together to develop and sustain a dysfunctional fusimotor complex
PRT is a nonpainful therapeutic intervention that limits pain and spasm and restores range of motion
PRT can be integrated into the overall treatment plan for both acute and chronic maladies
Evidence is mounting to support the efficacy of PRT for the treatment and prevention of somatic dysfunction in all populations and clinical settings
