4 What is a Trigger Point? Trigger points are discrete, focal, hyperirritable spots located in a taut band of skeletal muscle. They produce pain locally and in a referred pattern and often accompany chronic musculoskeletal disorders. Acute trauma or repetitive microtrauma may lead to the development of stress on muscle fibers and the formation of trigger points. Patients may have regional, persistent pain resulting in a decreased range of motion in the affected muscles.

6 The Trigger Point

7 Where do TPs manifest? These include muscles used to maintain body posture, such as those in the neck, shoulders, and pelvic girdle. Trigger points may also manifest as tension headache, tinnitus, temporomandibular joint pain, decreased range of motion in the legs, and low back pain.

8 Physical exam of Trigger Points Palpation of a hypersensitive bundle or nodule of muscle fiber of harder than normal consistency is the physical finding typically associated with a trigger point. Palpation of the trigger point will elicit pain directly over the affected area and/or cause radiation of pain toward a zone of reference and a local twitch response.

9 Treatments to Consider for TPs OMT Soft Tissue: Ischemic Compression Strain/CS MFR FPR Still Spray and Stretch TPI (trigger point injections) Neural Therapy PT Posture education Watch for trigger point irritation Muscle relaxants

10 Treatments cont d NSAIDs Lidoderm patch Tylenol Narcotics Short term use is best Narcotic contract is a must Urine drug testing is a must Drug monitoring system eg pill counts HA Meds (BB, CCB, Antiepilectics, Triptans)

11 OMT Techniques to Treat TPs

12 OMT of the Trigger Point Soft Tissue Techniques Ischemic compression Hold pressure on the TP for 30 to 60 seconds Home teaching Home devices Massotherapy

13 OMT of the Trigger Point Strain/Counterstrain Locate the tender point. Place in a position of relief by wrapping the point Hold for 90 seconds Slowly return to neutral position

14 OMT of the Trigger Point Myofascial Release Locate Tender Point Take tissues surrounding the point to a position of ease Hold for 30 to 60 seconds or until you feel tissues release Return to neutral

15 OMT of the Trigger Point Facilitated Positional Release MFR + Vector compressive force Locate tender point. Take to a position of ease Add a vector compressive force through the TP for 5 seconds Return to neutral

16 OMT of the Trigger Point A.T. Still Technique FPR + a ROM around the compressive force. Locate Tender Point Take tissues surrounding the point to a position of ease Add a vector compressive force through the TP for 5 seconds Take the Tissue/Limb in a ROM around the point Demonstrate with C-spine

17 OMT of the Trigger Point Spray and Stretch Spray skin coolant in the direction of pain pattern and passively stretch in between sprays Ethyl Chloride

18 Adjunct to OMT: TP Injections

19 Equipment Needed for Trigger-Point Injection Rubber gloves Gauze pads Alcohol pads for cleansing skin 3- or 5-mL syringe Lidocaine (Xylocaine, 1 percent, without epinephrine) or procaine (Novocain, 1 percent) 22-, 25-, or 27-gauge needles of varying lengths, depending on the site to be injected Adhesive bandage

20 Contraindications to Trigger-Point Injection Anticoagulation or bleeding disorders Aspirin ingestion within three days of injection The presence of local or systemic infection Allergy to anesthetic agents Acute muscle trauma Extreme fear of needles

21 Complications of Trigger-Point Injections Vasovagal syncope Skin infection Pneumothorax; avoid pneumothorax complications by never aiming a needle at an intercostal space. Needle breakage; avoid by never inserting the needle to its hub. Hematoma formation; avoid by applying direct pressure for at least two minutes after injection

22 Needle Selection The choice of needle size depends on the location of the muscle being injected. The needle must be long enough to reach the contraction knots in the trigger point to disrupt them. A 22-gauge, 1.5-inch needle is usually adequate to reach most superficial muscles. For thick subcutaneous muscles such as the gluteus maximus or paraspinal muscles in persons who are not obese, a 21-gauge, 2.0-inch needle is usually necessary. A 21-gauge, 2.5-inch needle is required to reach the deepest muscles, such as the gluteus minimus and quadratus lumborum, and is available as a hypodermic needle.

23 Trigger Point Injections: Hypodermic Needles

24 Needle Selection Using a needle with a smaller diameter may cause less discomfort; however, it may provide neither the required mechanical disruption of the trigger point nor adequate sensitivity to the physician when penetrating the overlying skin and subcutaneous tissue. A needle with a smaller gauge may also be deflected away from a very taut muscular band, thus preventing penetration of the trigger point. The needle should be long enough so that it never has to be inserted all the way to its hub, because the hub is the weakest part of the needle and breakage beneath the skin could occur.

26 Accupuncture Needles

27 Trigger Point Injections Needle Diameter Hypodermic Gauge

28 Injection Solutions An injectable solution of 0.5 to 1 % lidocaine or 1 % procaine is usually used. Several other substances, including diclofenac (Voltaren), botulinum toxin type A (Botox), and corticosteroids, have been used in trigger-point injections. However, these substances have been associated with significant myotoxicity. Procaine has the distinction of being the least myotoxic of all local injectable anesthetics.

29 Trigger Point Injections 0.5% Lidocaine cc into each muscle 30ga 1.5 inch needle Avoid use in face Inject 4-10 sites per session, in same region 1% Lidocaine 27 G needle, 1.25"long 3 cc syringe Inject cc per site Avoid use in face Inject 4-10 sites per session, in same region

30 Injection Technique Once a trigger point has been located and the overlying skin has been cleansed with alcohol, the clinician isolates that point with a pinch between the thumb and index finger or between the index and middle finger, whichever is most comfortable.

31 Injection Technique Using sterile technique, the needle is then inserted 1 to 2 cm away from the trigger point so that the needle may be advanced into the trigger point at an acute angle of 30 degrees to the skin. The stabilizing fingers apply pressure on either side of the injection site, ensuring adequate tension of the muscle fibers to allow penetration of the trigger point but preventing it from rolling away from the advancing needle.

32 Injection Technique Before advancing the needle into the trigger point, the physician should warn the patient of the possibility of sharp pain, muscle twitching, or an unpleasant sensation as the needle contacts the taut muscular band. To ensure that the needle is not within a blood vessel, the plunger should be withdrawn before injection. A small amount (0.2 ml) of anesthetic should be injected once the needle is inside the trigger point. The needle is then withdrawn to the level of the subcutaneous tissue, then redirected superiorly, inferiorly, laterally and medially, repeating the needling and injection process in each direction until the local twitch response is no longer elicited or resisting muscle tautness is no longer perceived.

33 Post-injection Management After injection, the area should be palpated to ensure that no other tender points exist. If additional tender points are palpable, they should be isolated, needled and injected. Pressure is then applied to the injected area for two minutes to promote hemostasis. A simple adhesive bandage is usually adequate for skin coverage. One study emphasizes that stretching the affected muscle group immediately after injection further increases the efficacy of trigger point therapy. Travell recommends that this is best performed by immediately having the patient actively move each injected muscle through its full range of motion three times, reaching its fully shortened and its fully lengthened position during each cycle.

34 Post Injection Management Postinjection soreness is to be expected in most cases, and the patient's stated relief of the referred pain pattern notes the success of the injection. Re-evaluation of the injected areas may be necessary, but reinjection of the trigger points is not recommended until the postinjection soreness resolves, usually after three to four days. Repeated injections in a particular muscle are not recommended if two or three previous attempts have been unsuccessful. Patients are encouraged to remain active, putting muscles through their full range of motion in the week following trigger-point injections, but are advised to avoid strenuous activity, especially in the first three to four days after injection

35 Myofascial Pain Syndrome (MPS) Characterized by the development of Myofascial trigger points that are locally tender when active Refer pain through specific patterns to other areas of the body. Due to many causes like trauma, arthritis, deconditioning. Trigger points are usually associated with a taut band, a ropey thickening of the muscle tissue.

98 Documentation Because injections are considered surgical procedures, they require a procedure note. The procedure note should include a signed consent, documentation of the anatomic location, preparation of the site, local anesthetic administration, name and dosage of drug administered, and patient reaction to procedure. Documentation should also include all postoperative instructions related to the procedure.
