Savarese Ch 11: Chapman's Points and Trigger Points Flashcards
What does a Chapman’s point represent?
Somatic manifestation of a visceral dysfunction.
They are thought to represent viscera-somatic reflex.
Describe what Chapman’s points feel like anteriorly:
Smooth, firm, discretely palpable nodules, approximately 2-3 mm in diameter, located within the deep fascia o on the periosteum of the bone.
Describe what Chapman’s points feel like posteriorly and where they are located:
Most are located between the spinous and transverse processes of vertebrae.
Described as rubbery, similar to tissue texture changes associated with the classic viscera-somatic reflex.
What happens if you push on a Chapman’s reflex
Gentle pressure at a Chapman’s point will usually elicit a sharp, nonradiating, and exquisitely distressing pain.
Anterior location of Appendix Chapman’s reflex point:
**At the tip of the right 12th rib
Only one bolded
Posterior location of the Appendix Chapman’s point:
At the transverse process of T 11 vertebrae.
**The presence of this particular reflex point helps to direct the differential diagnosis more toward ACUTE APPENDICITIS. **
Adrenal Chapman point
Anterior: 2” superior and 1” lateral to the umbilicus
Posteriorly: Between the spinous and transverse processes of T11 and T12
Kidney Chapman point
Anterior: 1” superior and 1” lateral to the umbilicus
Posterior: Between the spinous and transverse processes of T12 and L1
Colon chapman point:
On the lateral thiugh within the iliotibial band and the greater trochanter to just above the knee
What is a Trigger point? (Travell’s Myofascial Trigger Point)
It is a hypersensitive focus, usually within a taut band of skeletal muscle or in the muscle fascia.
-Painful upon compression
-Characteristic referred pain, tenderness, and autonomic phenomena
Key = reproducible referred pain upon compression!
What does a trigger point represent?
Bolded
Represents the somatic manifestation of a viscera-somatic, somato-visceral, or somato-somatic reflex.
How do you treat a trigger point?
All methods use a neurological or vascular method.
- *Spray and stretch using vapocoolant spray
- *Injection w/ local anesthetic or dry neeling
- Muscle energy
- Myofascial release
- Ultrasound, reciprocal inhibition, or ischemic compression
Who first introduced tenderpoints
Lawerence Jones, DO
How do Tenderpoints differ from Trigger points?
Tenderpoints DO NOT refer pain beyond the location compressed.
What is a tenderpoint?
Small, hypersensitive points in the myofascial tissues of the body -used as diagnostic criteria, and as a treatment monitor for counter strain.
