Define Myofascial Trigger Point (TrP) | A firm, palpable, highly irritable spot in a taut band of muscle fibers or fascia characterized by exquisite tenderness, referred pain and loss of range of motion. |
Define Pain Referral Zone (PRZ) | The specific regions of the body at a distance where phenomena (sensory, motor, and/or autonomic) caused by the TrP are observed. |
What is an Essential Pain Zone (area) | The region of referred pain present in nearly every client when the TrP is active. |
What is the Spillover Pain Zone (area) | The region where some, but not all, clients experience referred pain. |
The intensity and extent of the referred pain pattern is depentant more on what than on the size of the muscle and/or TrP. | Level of irritability. |
What is named as the most common reason for the formation of a TrP | Musculoskeletal Dysfunction |
What are the two most common patterns occuring as a result of soft tissue dysfunction | Sustained Hypertonicity and Sustained Inhibition |
What are the two classifications of trigger points | Active and Latent |
Describe Sustained Hypertonicity | Continuous muscle tightness |
Describe Sustained Inhibition | Continuous muscle weakness |
What is an active TrP | A trigger point that is currently causing pain at the site of the dysfunction, and usually in the PRZ. (A.K.A. Awake TrP) |
What is a latent TrP | A trigger point not currently causing pain unless activated by palpation |
What are the two types of trigger points | key/primary and satellite |
What are common causes for Sustained hypertonicity and inhibition | Static Stress; Muscle Injury; Joint Dysfunction; Emotional/Psychological Stress; Chronic Overuse; Disuse (Atrophy); Viscerosomatic Reflexes; Muscle Imbalance |
What is a myofascial adhesion | Bound up tissue(s) within a muscle |
What are the three most common pathways for a PRZ to follow | Fascial Pathways; Nerve Pathways; Meridian Pathways |
Name the pre-20th century author who did research in or about 1843 and found "muscle calluses" or tender, tight cords/bands in the muscles | Froriep |
Name the American in 1900 coining the term "muscular rheumatism" | Alder |
From 1904 - 1915, who intorduced the new term "fibrositis" describing the ame symproms? | Four Englishmen (unnamed) |
