Evaluation of Swing-Induced Linear Vestibular Stimulation in Women with Premenstrual Syndrome Using Physiological, Psychological, and Biochemical Parameters

Abstract

Background: Premenstrual syndrome (PMS) is a common condition in women that affects physical,
psychological, and social well-being. Linear vestibular stimulation has been proposed as a non-pharmacological
intervention for managing PMS symptoms. Objective: This study aimed to evaluate the efficacy of linear
vestibular stimulation in the treatment of PMS. Materials and Methods: An experimental study was conducted
on 100 female volunteers aged 18–30 years. Linear vestibular stimulation was administered using a conventional
swing. Various physiological, hormonal, hematological, and psychological parameters were recorded before
and after the intervention and compared. Results: Serum cortisol, triiodothyronine, thyroxine, and thyroidstimulating hormone levels showed a gradual month-by-month decrease following linear vestibular stimulation.
Hematological analysis revealed a reduction and stabilization of monocyte counts in certain women compared
with controls. Females across different age groups and body mass index categories showed no stress-induced
increase. Lymphocyte counts significantly decreased while remaining within normal limits compared to baseline
values. Quality-of-life scores, including physical, psychological, social, and environmental domains, improved
after 2 months of stimulation. Depression anxiety stress scales (DASS-42) scores for anxiety, depression, and
stress showed a decrease. However, no significant difference was observed in DASS stress levels between control
and vestibular groups before and after stimulation. Conclusion: Linear vestibular stimulation appears to be an
effective non-pharmacological approach in controlling PMS-related symptoms and improving overall well-being.
