The higher the number of active trigger points (TPs), the greater the physical burden of headache and the higher the anxiety level. Gender differences in TP prevalence and TPI efficacy have been described in the literature. For example, the number of active TPs seems directly associated with anxiety levels in women but not in men.123 Although TPs appear to be more closely associated with anxiety than depression,124 depression associated with muscle tension does improve with TPIs. European studies have demonstrated a decrease in scores on the Hamilton Depression Rating Scale and Hamilton Anxiety Rating Scale following TPI treatment.125 The effect may be indirect, as when a patient’s pain is relieved, sleep and other psychiatric symptoms improve.126

A randomized controlled trial by Castro Sánchez et al127 demonstrated that dry needling therapy in patients with fibromyalgia syndrome (FMS) showed improvements in pain pressure thresholds, body pain, vitality, and social function, as well as total FMS symptoms, quality of sleep, anxiety, hospital anxiety and depression, general pain intensity, and fatigue.

Myofascial pain syndrome, catastrophizing, and muscle tension are common in patients with depression, anxiety, and somatization. Local TPI therapy aimed at inactivating pain generators is supported by moderate quality evidence. All manner of therapies have been described, including injection of saline, corticosteroids, local anesthetic agents, and dry needling. BT injections in chronic TPs are also practiced, though no specific injection therapy has been reliably shown to be more advantageous than another. The benefits of TPIs may be derived from the needle itself rather than from any specific substance injected. Stimulation of a local twitch response with direct needling of the TP appears of importance. There is no established consensus regarding the number of injection points, frequency of administration, and volume or type of injectate.128

Adverse effects of TPIs relate to the nature of the invasive therapy, with the risk of tissue damage and bleeding. Pneumothorax risk is present with needle insertion at the neck and thorax.129 Patients with diabetes may experience variations in blood sugar control if steroids are used.

Bottom Line

Interventional treatment modalities that may have a role in psychiatric treatment include IV administration of ketamine, aducanumab, lecanemab, brexanolone, magnesium, scopolamine, and clomipramine. Other interventional approaches include stellate ganglion blocks, glabellar botulinum toxin injections, and trigger point injections.
