“…In another study by Fridén et al (13), a tendency towards greater postural sway in the midluteal phase was detected among women with premenstrual syndrome. Darlington et al (53) found that the menstrual cycle phase had no significant effect on anterior-posterior sway, but it did significantly affect lateral sway. They further declared that sway on day 5 was significantly greater than on days 12 and 21, and that sway was significantly greater on day 25 than on day 21.…”

Background/aim: To investigate differences in state anxiety, spinal posture and mobility, postural competency, and stability across the menstrual cycle in active women. Materials and methods:Thirteen physically active women (18-25 years) with a regular menstrual cycle were recruited. Anxiety with the Spielberger State Trait Anxiety Inventory; spinal posture, mobility, and competency with a Spinal Mouse device (Idiag, Fehraltorf, Switzerland); and postural stability with a Biodex Balance System SD (Biodex Medical Systems, Inc., Shirley, NY, USA) were evaluated across phases of the menstrual cycle.Results: No significant differences were observed between phases of the menstrual cycle for state anxiety, spinal posture, mobility, or competency (P > 0.05). No differences were found for static postural stability (P > 0.05); however, a significant difference was detected in dynamic postural stability within three phases of the menstrual cycle (P < 0.05). The highest values of overall stability, anterior-posterior and mediolateral indexes were at menses; the lowest values were at the midluteal phase. Conclusion:State anxiety, spinal posture, mobility, and postural competence did not change across the menstrual cycle. However, dynamic stability declined in menses. Improving awareness of dynamic stability impairment during menses may be important toward injury prevention in active women.

“…PMT affects about 75% of women in the reproductive age. [8][9][10] A decreased CAL latency and an increased SM precision during the postmenstrual period diverge from the findings of a study 11 that monitored two menstrual cycles of 12 subjects and concluded that hormone changes within the cycle had no significant effect on the optokinetic function, and that only lateral postural stability was affected.…”

Hormonal disorders in the menstrual cycle can affect labyrinthine fluid homeostasis, causing balance and hearing dysfunctions. Study Design: Clinical prospective. Aim: compare the results from vestibular tests in young women, in the premenstrual and postmenstrual periods. Materials and Methods: twenty women were selected with ages ranging from 18 to 35 years, who were not using any kind of contraceptive method for at least six months, and without vestibular or hearing complaints. The test was carried out in each subject before and after the menstrual period, respecting the limit of ten days before or after menstruation. Results: there was a statistically significant difference in the menstrual cycle phases only in the following vestibular tests: calibration, saccadic movements, PRPD and caloric-induced nystagmus. We also noticed that age; a regular menstrual cycle; hearing loss or dizziness cases in the family; and premenstrual symptoms such as tinnitus, headache, sleep disorders, anxiety, nausea and hyperacusis can interfere in the vestibular test. Conclusion: there are differences in the vestibular tests of healthy women when comparing their pre and postmenstrual periods.

“…Postural control in premenopausal women during the menstrual cycle has been less investigated. Darlington et al [11] detected a greater postural sway in the LP and the early FP of the menstrual cycle. However, in the study by Darlington et al [11], PMS scores were not included.…”

Altered Postural Control during the Luteal Phase in Women with Premenstrual Symptoms

et al. 2005

The purpose of this study was to investigate postural control in women with and without premenstrual symptoms (PMS) in three hormonally verified phases of the menstrual cycle. Thirty-two women were recruited to participate in the study and 25 of these women were included in the results. Menstrual cycle phases were determined by sex hormone analyses in serum and LH detection in urine. A prospective rating of PMS was used to divide the subjects into two groups: one with PMS (cyclic) and one without (non-cyclic). For measurement of postural control, subjects stood on a force platform (AMTI^®) in two-legged stance (eyes open and closed) and one-legged stance (eyes open and closed). There were no significant differences in the two-legged stance between the phases of the menstrual cycle or between groups. In one-legged stance with eyes open, there was a significant increase in postural displacement in the mid-luteal phase in the cyclic group, but no differences were detected between phases in the non-cyclic group. These findings may be related to the previously reported increased injury rate and psychomotor slowing in the luteal phase in women with PMS.
