Acupressure as a non-pharmacological treatment for depression: Neurophysiological, biochemical, and psychological...

Depression is a common and serious psychological disorder with high prevalence and recurrence rates. Still, there are treatment-resistant depression in the clinic, so exploring other treatments is necessary. Acupressure is a non-invasive therapeutic method based on the principles of traditional Chinese medicine, which promotes health and relieves symptoms by applying pressure to specific acupoints on the body. Modern medical research on acupressure has gradually deepened, explaining and validating it through multiple perspectives, e.g., physiology, neurology, and biochemistry. However, the mechanisms underlying the treatment of depression with acupressure, the adoption of a multidisciplinary model of collaboration in treatment, and the improvement of the quality of related research have not yet been thoroughly described. Therefore, the present review summarized the mechanisms, including the neurophysiological, biochemical, and psychological mechanisms behind the treatment of depression with acupressure, its strengths (e.g., no side effects, easy operation, and good patient compliance), and limitations (e.g., individual differences in effects and lack of large-scale systematic studies) in treatment of depression and researches, and its potential for collaboration with other therapies (e.g., acupressure with medication, psychotherapy, and other Chinese medicine), and multidisciplinary approaches.
