Abstract

The objective of this study was to identify the effect of lumbar lordotic curve adjustment on head and neck posture in older adults. Methods Twenty healthy older participants (mean age 71.32) were photographed while watching monitor in sitting with or without lumbar roll support(length 28cm, diameter 10cm). The upper cervical angle and lower cervical angle were measured using the NIH ImageJ 1.32. Comparisons between upper and lower cervical angle with or without lumbar roll support were made using paired-t test analysis. Results Subjects demonstrated a significant difference in the mean upper and lower cervical angle. Mean difference of the upper cervical angle was about $2.83^{\circ}$ with and without lumbar roll support(p<0.005). Mean difference of the lower cervical angle was about $4.44^{\circ}$ with and without lumbar roll support(p<0.0001). Conclusions This study showed that healthy older adults demonstrated more ability to maintain an upright posture of cervical spine during lumbar lordotic curve maintenance with lumbar roll support than without lumbar roll support. When the clinicians consider improvement of the head and neck posture in older adults, they must incorporate adjustment in the lumbar region.
