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.

본 연구는 요추 지지대가 노인의 머리와 목 자세에 미치는 영향을 분석하고자 하였다. 20명의 신체 건강한 노인(평균 나이 71.32세)을 대상으로 측정하였으며, 앉은 자세에서 모니터를 시청하는 동안 요추만곡을 요추 지지대 사용 유무에 따라 조절하였다. 측정은 측면에서 사진을 촬영하였다. NIH ImageJ 1.32 프로그램을 사용하여 상부경추 굴곡 각도와 하부경추 굴곡 각도를 측정하였고 분석은 대응 t 검정을 사용하였다. 그 결과, 상부경추 굴곡 각도와 하부경추 굴곡 각도는 요추 지지대 적용 여부에 따라 유의한 차이가 있었다. 상부경추 평균 굴곡 각도는 요추 지지대 적용할 때가 적용하지 않을 때보다 약 $2.83^{\circ}$ 증가하였다(p<0.005). 하부경추 평균 굴곡 각도 역시 요추 지지대를 적용할 때 약 $4.44^{\circ}$ 증가되었다(p<0.0001). 이는 요추 지지대를 적용하였을 때 상부경추와 하부경추 굴곡을 증가시킴으로 머리와 목 자세에 좋은 영향을 주는 것을 의미한다. 따라서 노인의 머리와 목 자세 개선시 요추만곡 조절을 고려해야 할 것이다.
