Myofibroblasts -differentiated fibroblasts in response to strain and increased interstitial fluid -similar to smooth muscle -lend structural support -paracrine/endocrine functions **Exist in short term to facilitate wound healing
Myofascial Point system Clinical diagnosing system/treatment based on locating specific points on the body's surface
4 point-based myofascial systems 1. Counterstrain tender points 2. Chapman's reflex point 3. Trigger point 4. Acupuncture point
Theory behind counterstrain tenderpoints (Jones) locally tender myofascial points that DO NOT refer pain beyond that location. **Found mostly in muscle bellies and musculotendinous areas due to high concentration nocioceptive fibers
Diagnosing and treating Counterstrain Tenderpoints Diagnosing: Palpating specific, defind points both anteriorly and posteriorly Treatment: Move patient into position of comfort for 90/120 seconds, then passively return them to neutral
Theory behind trigger points (Travell) myofascial point that REFERS pain in a specific muscle
Diagnosing and treating trigger points Diagnosis: taut bands that feel like contracted muscle fiber. Produce a twitch reaction Treatment: Dry needling or injection
Difference between Trigger and tender points Tender points don't have: 1. characteristic pain pattern 2. radiating pain pattern when pressed 3. Taut bands present 4. Twitch response 5. Dermographia of skin over point **Both elicit jump sign when pressed and are located primarily in muscle t
Theory and diagnosis Chapman's reflex points Gangliform contractions (small, stringy, tender) representing a viscero-somatic reflex (caused by visceral dysfunction) **often found on the deep fascia or periostium.
Theory behind acupuncture points Found in areas of Lower Electrical Skin Resistance -depressed b/w muscle groupd allowing direct access to lamellar flow. -areas of Loose CT (overlying neurovascular bundle) Causes CNS activation of Endogenous opiod receptors and non-opiod pain inhibit
Diagnosing acupuncture points Tender to deep palpation without radiation elsewhere. Produces a tissue response when needled (histamine) -Shu points (posterior wall. organ specific) -Mu points (anterior wall. segmentally specific)
Similarities between all 4 point systems 1. tender with palpation 2. causes palpable tissue texture change 3. Somewhat predictable in location 4. Paired diagnostically as Ant&Post 5. Associated with pain (local or referred)
Treating acupuncture points Using a needle with 3 microvolts of electrical potential at body temperature. **takes 10-15 min to reach equilibrium (when erythema/histamine response disappears)
Dispersion acupuncture used to treat excess or acute conditions -electric potential 3 microvolts -10-15 minutes equilibrium
Tonification acupuncture used to treat deficiency or chronic illness -electric potential 10-15 microvolts -equilibrium within 60-90 min
