Análisis de la Morfología del Raquis Torácico y Lumbar en Mujeres Trabajadoras de una Cooperativa Hortofrutícola

The aim of this study was to analyze the sagittal spinal morphology of thoracic and lumbar spine in standing and sitting in women workers from a cooperative in the production, handling and marketing business of vegetable and fruit products. A total of 50 women (mean age: 43.62±8.43 years old) were evaluated. The Spinal Mouse system was used to mesasure the sagittal thoracic and lumbar curvatures in standing and relaxed sitting. The values for thoracic and lumbar curvatures were 32.74±8.76 and -21.66±19.12 in standing and 36.32±10.55 and -1.08±18.14 in sitting. A high frequency (86.0% and 68.3%) of normal thoracic kyphosis and lumbar lordosis were found in standing posture. While sitting the 74.0% and 20.0% presented thoracic hyperkyphosis and lumbar kyphosis. In conclusion, a high percentaje of women workers presented normality values in standing posture, although a high percentage of women were found with thoracic hyperkyphosis and lumbar flexed while sitting relaxed. It is recommended that these women carry out a program to improve their actitudinal postures in their work place.

Comodidad materna y reducción del dolor en mujeres con posición fetal occipitoposterior durante el parto con el uso de las posturas de decúbito lateral y manos-rodillas: Ensayo clínico aleatorizado

Objective: To assess the maternal comfort and reduction of pain associated with contractions during labor with “hands-knees” (HK) maternal posture compared with “lateral maternal postures toward the fetal back” in pregnant women with occipitoposterior (OP) fetal position. Methods: In the multicenter trial by randomization, 70 women with OP fetal position during labor took the lateral posture and 65 women the HK posture for at least 30 minutes. We analyzed maternal comfort, perceived pain, influence of epidural analgesia and use of fit-ball on posture HK. Results: Back pain and abdominal pain reduction was higher with HK posture. With lateral posture 78.6% of women expressed comfort versus 73.8% of women with HK posture. Regarding the lateral posture, the comfort with HK posture reduces in multiparous women, with an odds ratio (OR) of 0.29, for a confidence interval (CI) 95% 0.12 to 0.76, and epidural analgesia (OR= 0.39; CI 95%: 0.15-1.03), comfort with K posture is higher with reduction of pain (OR= 4.13, 95% CI: 1.34- 12.72) and abdominal pain compared with back pain (OR= 4.05, 95% CI: 1.36-11.85). Conclusions: Women consider comfortable lateral and HK maternal postures during labor. The lateral posture is most comfortable for multiparous and epidural analgesia. The reduction of pain during labor is higher with HK posture, recommending this posture in primiparous women without epidural analgesia.
