Factors Affecting Back Pain Of Women Sitting Inbreast Feeding Posture

บทคัดย่อ ( Abstract )

The benefits of breastfeeding are widely recognized and breastfeeding is being promoted worldwide. Sitting breastfeeding babies for a prolong period of time could result in considerable back pain. This paper examines the effects of breastfeeding sitting postures, as influenced by chair design, on back pain. Specific chair design variables investigated are backrest angle, lumbar support, and armrest. The participants, 12 Thai women, were asked to sit in variousbreastfeeding postures. The chair was adjustable so that the effects of backrest angle, lumbar support thickness, and armrest height on back pain could be studied. The percentage maximum voluntary contraction (MVC) of the back pain was measured by electromyography (EMG) in 90 min with 15 minutes breaks between different measurements.Follow up interviews were also conducted after each test. Sitting postures for breastfeeding as dictated by chair design, affect on back pain considerably. Increasing backrest angle from 90 to 110 degree resulted in a decrease in MVC value about 50% while increasing the angle further resulted in an increase in MVC value. Increasing lumbar support thickness from zero (no support) to 9 cm led to a reduction in MVC value of more than two thirds. Armrest height also had a large effect on MVC value. Using the armrest height of 21 cm resulted in almost 80% reduction in MVC value compared with the value when no armrest was used. Chair design affects back pain in women sitting in breastfeeding posture. Design variables; backrest angle, lumbar support thickness, and armrest height, all influence back pain. As back pain is important for the well-being of breastfeeding mothers, it is imperative to design chairs with proper design parameters in order to minimize back pain.
