Field, T., Hernandez-Reif, M., Hart, S., Theakston, H., Schanberg, S., Kuhn, C. & Burman, I. (1999). Pregnant women benefit from massage therapy. Journal of Psychosomatic Obstetrics & Gynecology, 20, 31-38.

Twenty-six pregnant women were assigned to a massage therapy or a relaxation therapy group for 5 weeks. Both groups reported feeling less anxious after the first session and less leg pain after the first and last session. Only the massage therapy group, however, reported reduced anxiety, improved mood, better sleep and less back pain by the last day of the study.
