    Comparative analysis of postural stability and risk of falling and developing disability among overweight and obese women over 40 years
    (Elsevier, 2024) Ucurum, Sevtap Gunay; Uzunlar, Hilal; Kirmizi, Muge; Altas, Elif Umay; Kaya, Derya Ozer
    Background: Increased body mass index (BMI) adversely affects the mechanics of the musculoskeletal system. It is known that obese people have poorer postural stability and mobility -related outcomes compared to normal weight people, but there is limited research comparing overweight and class 1 obese people, two consecutive and prevalent BMI categories. Aims: To compare postural stability, functional mobility, and risk of falling and developing disability between overweight and obese women, and to investigate the relationship of BMI and body weight with the outcomes. Methods: Thirty women with class 1 obesity and 30 overweight women were included. Standing postural stability with eyes -open and eyes -closed and stability limits were assessed using the Prokin system. The Timed Up and Go Test (TUG) was used to assess functional mobility and risk of falling ( >= 11 s) and developing disability ( >= 9 s). Results: The average center of pressure displacements on the y-axis (COPY) obtained during quiet standing with both eyes -open and eyes -closed were higher in obese women than overweight women (p < 0.05) and the effect sizes were moderate for the results. The COPY values in the eyes -open and eyes -closed conditions were correlated with BMI (r = 0.295 and r = 0.285, p < 0.05). Furthermore, the COPX value in the eyes -open condition and the TUG score were correlated with body weight (r = 0.274 and r = 0.257, p < 0.05). Conclusions: Obese women had poorer static standing stability in the anteroposterior direction than overweight women, while functional mobility and risk of falling and developing disability did not differ. Furthermore, BMI and body weight were related to poorer static standing stability.

    More neck pain, less spinal mobility, altered sitting posture: Sagittal spinal alignment and mobility in women with chronic neck pain
    (Elsevier, 2024) Unal, Nur Efsan; Ucurum, Sevtap Gunay; Kirmizi, Muge; Altas, Elif Umay
    Background: Increasing evidence suggests that people with chronic neck pain (CNP) may display altered biomechanics beyond the cervical spine. However, whether spinal alignment and mobility are associated with neck pain is not clarified. Objectives: To investigate whether there is a significant association between neck pain intensity and sagittal spinal alignment and mobility in people with CNP, and to examine whether sagittal spinal alignment and mobility differ according to pain intensity. Design: A cross-sectional study. Method: Forty-four women with CNP were included. The neck pain intensity at rest and during neck movements was assessed with the visual analogue scale (VAS). A skin-surface measurement device was used to assess sagittal alignment and mobility while sitting and standing. Linear regression analysis was used to assess associations. Participants were divided into two groups according to the pain intensity as group with mild pain (VAS <= 4.4 cm) and group with moderate to severe pain (VAS>4.4 cm) and compared using the analysis of covariance. Results: Greater resting pain was associated with a more forward trunk during sitting (Beta = 0.433, p < 0.05). Greater pain during neck movements was associated with increased lumbar lordosis during sitting (Beta = -0.376, p < 0.05). Classified by pain intensity at rest, trunk mobility while sitting was lower and forward trunk inclination and sacral kyphosis while sitting were higher in those with moderate/severe pain (eta(2)(p) = 0.093-0.119, p < 0.05). By pain intensity during neck movements, women with moderate/severe pain exhibited lower sacral mobility while sitting (eta(2)(p) = 0.129, p < 0.05). Conclusions: Addressing the entire spine in the assessment and management of CNP may help reduce pain.

    Sagittal spinal alignment and mobility and their relation to physical function in women with and without mild-to-moderate knee osteoarthritis
    (Elsevier Sci Ltd, 2023) Ucurum, Sevtap Gunay; Kirmizi, Muge; Altas, Elif Umay; Kaya, Derya Ozer
    Recent studies suggest that patients with lower extremity osteoarthritis may have altered spinal posture. We aimed to investigate age and body mass index-adjusted sagittal spinal alignment and mobility and their relation to physical function in women over 40 years of age with and without mild-to-moderate knee osteoarthritis (KOA). Thirty-two women with unilateral mild-to-moderate KOA and thirty-two asymptomatic women were included. A skin-surface device was used to assess sagittal alignment and mobility of the thoracic, lumbar, and sacral regions and trunk inclination angle. Physical function was assessed using the Timed Up and Go test. Analysis of covariance was used to compare groups and correlation coefficients were calculated separately for two groups. Women with KOA had higher thoracic kyphosis and lumbar lordosis compared to asymptomatic women (p < 0.05). The mean differences were 6.60 (%95 Confidence Interval 1.38;11.82) and-5.63 (-10.06;-1.20) for thoracic kyphosis and lumbar lordosis, respectively. Physical function score was moderately correlated with trunk inclination angle and lumbar, sacral, and trunk inclination mobility in asymptomatic women (r = 0.400,-0.504,-0.602, and-0.681, p < 0.05), but a significant correlation was not found in women with KOA (p > 0.05). In conclusion, women with KOA had altered spinal alignment. Spinal alignment and mobility were related to physical function in asymptomatic women over 40 years of age. Addressing sagittal spinal alignment in the clinical management of KOA may provide valuable data, especially for preventing possible spinal disorders.
