A wide range of relaxation techniques are used for therapeutic purposes. In Switzerland, researchers evaluated the anxiolytic effects of 10 minutes of progressive muscle relaxation and guided imagery in 39 pregnant women.31 Women randomly assigned to progressive muscle relaxation were instructed to systematically tense and then release muscle groups throughout their body in sequential order. Women assigned to the guided imagery intervention were told to imagine a safe place and to think of someone who could confer security and reassurance. The remainder of the women were assigned to a control group, where they sat quietly without any formal instructions. Researchers found that each group had a decrease in STAI scores and salivary cortisol levels immediately after the intervention.31
The relaxation response was first described in 1975 by Herbert Benson, MD, as a deep meditative state characterized by a decrease in tension, heart rate, and breathing rate. Several techniques can induce this state, including hypnosis, progressive muscle relaxation, yoga, and transcendental meditation.32 In a study of 15 healthy older adults (age 65 to 80), researchers randomly assigned participants to a relaxation response training group or to a control group.33 The relaxation response training included meditation, imagery, and relaxation techniques. After 5 weeks, participants who received the relaxation response training had marginally significant decreases in STAI scores compared with those in the control group.33
Consider these therapies as adjuncts
Our review of select positive RCTs (Table12-14,17,20,22,23,25,27,29-31,33) suggests that some nonpharmacologic/nonpsychotherapeutic adjunctive interventions may have beneficial effects for patients who have anxiety. Several of the controlled studies we reviewed demonstrated that these interventions are superior to placebo. The reductions in both anxiety severity as measured by the STAI and cortisol levels suggests that some of these complementary therapies deserve a second look as useful adjuncts to established anxiety treatments.
Bottom Line
A review of select randomized controlled trials suggests that some complementary therapies may be helpful as adjunctive therapy in patients with anxiety. These include yoga, massage therapy, aromatherapy massage, pet therapy, Qigong, auricular acupressure, reiki touch therapy, acupuncture, music therapy, and relaxation techniques.
