The Relationship Between Neuropathic Pain and Spinal Alignment: Independent Risk Factors for Low Quality of Life in Middle-Aged and Elderly People

Study Design. Prospective research in middle-aged and elderly people. Objective. To investigate low back pain (LBP) and neuropathic pain (NeP); spinal alignment and range of motion (ROM); spinal degenerative changes in plain radiography; osteoporosis; muscle strength; and physical ability as possible risk factors for poor quality of life (QOL). Summary of Background Data. The aging of society has led to an increase in elderly people with chronic pain, including LBP and NeP. However, there has been no analysis of NeP and spinal sagittal alignment as potential risk factors for decreased QOL in the healthy general population. Methods. The subjects were 1128 people (male 473, female 655, average age: 64.3 yrs) who attended an annual health checkup in Yakumo study. The prevalence of LBP and sciatica were investigated using a visual analogue scale (VAS), and NeP was defined as more than or equal to 13 points on the painDETECT questionnaire. Sagittal spinal alignment with spinal ROM was also measured. Body mass index, muscle strength, physical ability, osteoporosis, and lumbar degenerative changes were measured, and 36-item short-form health survey (SF-36) was used for QOL analysis. Results. NeP was present in 113 people (10%). The NeP (+) subjects had significantly more severe pain, lower gait speed, higher osteoporosis rate, lumbar kyphosis, and larger spinal inclination (P
