Effects of qi therapy (external qigong ) on premenstrual syndrome: a randomized placebo-controlled study.

Abstract

To assess the effects of qi therapy on premenstrual symptoms in women with premenstrual syndrome (PMS). A randomized placebo-controlled trial. Thirty-six (36) college women with symptoms of PMS. After 2 months of screening, subjects with PMS were randomized to receive real qi therapy (18 subjects) or placebo (18 subjects). The subjects were informed that they would receive one of two types of treatment. They did not know which treatment they received. Each intervention was performed eight times during the second and third cycles with subjects completing a PMS diary. There were significant improvements in the symptoms of negative feeling, pain, water retention, and total PMS symptoms in subjects receiving qi therapy compared to placebo controls. Qi therapy may be an effective complementary therapy for managing the symptoms of PMS.
