Trigger-point hypersensitivity in the gluteus maximus and gluteus medius often produces intense pain in the low back region.15 Examples of trigger-point locations are illustrated in Figure 1.16, Palpation of a hypersensitive bundle or nodule of muscle fiber of harder than normal consistency is the physical finding most often associated with a trigger point.10 Localization of a trigger point is based on the physician's sense of feel, assisted by patient expressions of pain and by visual and palpable observations of local twitch response.10 This palpation will elicit pain over the palpated muscle and/or cause radiation of pain toward the zone of reference in addition to a twitch response.

Endogenous opioid release may play a role in TPIs. Myofascial trigger points are self-sustaining hyperirritative foci that may occur in any skeletal muscle in response to strain produced by acute or chronic overload. The Spray and Stretch technique involves passively stretching the target muscle while simultaneously applying dichlorodifluoromethane-trichloromonofluoromethane (Fluori-Methane) or ethyl chloride spray topically.5 The sudden drop in skin temperature is thought to produce temporary anesthesia by blocking the spinal stretch reflex and the sensation of pain at a higher center.5,10 The decreased pain sensation allows the muscle to be passively stretched toward normal length, which then helps to inactivate trigger points, relieve muscle spasm, and reduce referred pain.5, Dichlorodifluoromethane-trichloromono-fluoromethane is a nontoxic, nonflammable vapor coolant spray that does not irritate the skin but is no longer commercially available for other purposes because of its effect in reducing the ozone layer.

After intra-articular injection, corticosteroids function to suppress inflammation and decrease erythema, swelling, heat, and tenderness of the inflamed joint.

Furthermore, manual methods are indicated for patients who have an extreme fear of needles or when the trigger point is in the middle of a muscle belly not easily accessible by injection (i.e., psoas and iliacus muscles).10 The goal of manual therapy is to train the patient to effectively self-manage the pain and dysfunction. 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.10, 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.

TPIs may be classified according to the substances injected, which may include local anesthetic, saline, sterile water, steroids, nonsteroidal anti-inflammatory drugs, botulinum toxin, 5-HT3 receptor antagonists, or even dry needling.1038 Although this chapter focuses on TPIs for chronic low back pain (CLBP), trigger points may occur elsewhere in the body. The agents differ according to potency (Table 3), solubility, and crystalline structure. A common diagnostic indication for placing a needle in a joint is the aspiration of synovial fluid for evaluation. Animal and human models suggest that the local twitch responses and referred pain associated with trigger points are related to spinal cord reflexes.34 Simons and Hong suggested that there are multiple trigger point loci in a region that consist of sensory (nociceptors) and motor (abnormal end-plates) components.63 By modifying the peripheral nociceptive response (desensitization), the nociceptive input to higher neurologic centers of pain and resulting increased muscle fiber contraction are blocked. It is used in the management of certain types of edema (fluid retention and swelling; excess fluid held in body tissues,) gastrointestinal disease, and certain types of arthritis. Before The number of trigger points injected at each session varies, as does the volume of solution injected at each trigger point and in total.
