Static and dynamic postural control of postpartum women of different delivery methods

Investigation of postural sensory organization in women with and without primary dysmenorrhea in three phases of the menstrual cycle

BACKGROUND

The effects of the menstrual cycle in women with and without primary dysmenorrhea on phase-related postural sensory organization are controversial.

RESEARCH QUESTION

This study was carried out to examine postural sensory organization in three phases of the menstrual cycle in women with and without primary dysmenorrhea and to evaluate whether there is a difference between women with/without primary dysmenorrhea in this regard.

METHODS

Women aged 18-30 years were divided into two groups as primary dysmenorrhea group (PDG, n = 14) and control group (CG, n = 15). Computerized dynamic posturography were applied to the participants on the follicular, ovulation, and luteal phases of the menstrual cycle. Outcome measures were antero-posterior and medio-lateral Sensory Organization Test (SOT-somatosensory, vestibular and visual scores) and Limits of Stability test (LoS). The findings obtained were analyzed with the two-factor ANOVA, paired samples t test, and independent samples t test.

RESULTS

In the PDG, follicular phase antero-posterior somatosensory scores were lower compared to luteal phase (p = 0.002). Follicular phase antero-posterior and medio-lateral vestibular scores were lower than ovulation (p = 0.003, p = 0.004, respectively) and luteal (p = 0.005, p = 0.001, respectively) phases. Follicular phase LoS scores were lower than ovulation (p = 0.001) and luteal (p = 0.002) phases. In the CG, ovulation phase antero-posterior somatosensory scores were lower than follicular phase (p = 0.003). Follicular phase LoS scores were lower than ovulation phase (p = 0.002). The PDG had lower follicular phase antero-posterior somatosensory (p = 0.019), vestibular (p = 0.031), and medio-lateral somatosensory (p = 0.019) scores than those of the CG. The PDG had lower luteal phase antero-posterior somatosensory scores than those of the CG (p = 0.029). The PDG showed lower follicular phase LoS scores than those of the CG (p = 0.009).

SIGNIFICANCE

This study revealed that primary dysmenorrhea impairs postural sensory organization. Decreased sensory organization may predispose women to injury. The risk of injury should be investigated and necessary precautions should be taken.

Plantar sensation, proprioception, and balance levels in pregnant women with gestational diabetes mellitus

BACKGROUND

The aim of the study was to compare plantar sensation, proprioception, and balance levels between pregnant women with Gestational Diabetes Mellitus and healthy pregnant women. Also, we aimed to investigate the relationship between parameters that were found to be different and sensory sensitivity, balance, and position sense.

METHODS

Seventy-two pregnant women (35 with Gestational Diabetes Mellitus and 37 controls) were included in this case-control study. Plantar sensory levels of the ankle joint (Semmes-Weinstein Monofilament-Test), position sense (digital inclinometer), and balance levels (Berg Balance Scale) were evaluated.

FINDINGS

The Gestational Diabetes Mellitus group could not detect small filament thickness in the heel region compared to the control group (p < 0.05). In the ankle proprioception measurements of the Gestational Diabetes Mellitus group, deviation angle values were higher (p < 0.05) and the balance level was lower compared to the control group (p < 0.001). In addition, there was a positive correlation between glucose metabolism parameters and plantar sense and proprioception and a negative correlation with balance level (p < 0.05).

INTERPRETATION

Plantar sense in the heel area, ankle joint position, and balance level of pregnant women with Gestational Diabetes Mellitus were lower than those of the healthy pregnant women. Disruption of glucose metabolite levels, which causes Gestational Diabetes Mellitus, is related to poorer balance, ankle position sense, and plantar sense in the heel. We recommend evaluating position sense and plantar sense for postural instability and risk of falling in pregnant women with Gestational Diabetes Mellitus.
