Objective: To determine whether reflexology therapy--the application of manual pressure to reflex points on the ears, hands, and feet that somatotopically correspond to specific areas of the body--can significantly reduce premenstrual symptoms compared to placebo treatment.
Conclusion: These clinical findings support the use of ear, hand, and foot reflexology for the treatment of PMS.
