Does aerobic exercise work better than vestibular stimulation for PMS?

Objective: To determine the effect of aerobic exercise versus vestibular stimulation on lipid profile in premenstrual syndrome. Subjects and Methods: Sixty patients with premenstrual syndrome had regular menstrual cycles were participated in this study. Their ages were ranged between 23-30 year. Their body mass index did not exceed 30 kg/ m2. They were not participating in physical therapy exercise program at the last 3 months. Patients with cardiovascular problems, pulmonary problems and endometriosis are excluded from the study. All patients were divided randomly into two equal groups (A&B). Group A: It consisted of thirty patients with premenstrual syndrome. They were treated by aerobic exercises in the form of treadmill training at moderate intensity of 60- 70% of the maximum heart rate, 3 times per week for 2 months. Group B: It consisted of thirty patients with premenstrual syndrome. They were treated by vestibular stimulation, 3 times per week for 2 months. Outcome measures: Total cholesterol level, HDL, LDL, triglycerides were assessed for all patients before and after treatment in both groups (A&B). Premenstrual syndrome scale was used to confirm the diagnosis of PMS before study and to evaluate the severity of PMS symptoms for all patients in both groups (A&B) before and after treatment. Results: Results revealed that, between groups; pretreatment, there was no significant difference between both groups A and B in total cholesterol, triglycerides, HDL, LDL and premenstrual syndrome scale. While post treatment, there was significant difference between both groups A and B in total cholesterol, triglycerides, HDL, LDL and premenstrual syndrome scale (with favour of group A; more decrease in total cholesterol, triglycerides, LDL and premenstrual syndrome scale and more increase in HDL). Conclusion: Aerobic exercise was found to be effective more than vestibular stimulation on lipid profile in premenstrual syndrome, in relieving stress and symptoms of PMS.
