만성 요통 환자와 요통이 없는 건강한 대상자의 척추 뼈분절의 압통역치 수준 비교와 만성 요통 환자에 통증 수준, 요통 기능장애 및 심리 수준 간에 상관성 = Comparison of the pressure pain thresholds the vertebral segments between patients with chronic lower back pain and healthy individuals, and correlation between pain, lower back pain dysfunction, and psychological status in patients with chronic lower back pain Tests in Patients with Chronic Low Back Pain

다국어 초록 (Multilingual Abstract)

Purpose: This study aimed to compare pressure pain thresholds (PPTs)
in the vertebral segments between patients with chronic lower back pain - 37
- 38
(CLBP) and healthy participants without back pain and to determine the
correlation between vertebral bone-segment PPT and pain level, lower
back pain dysfunction, and psychological status in patients with CLBP.
Participants: The CLBP group included patients with persistent lower
back pain for >3 months, a diagnosis of CLBP by a medical specialist, and
a pain intensity score ≥3 on a numerical rating scale (NRS) with scores
ranging from 0 to 10. Participants aged between 18 and 65 years who did
not have back pain for >7 days in the past 12 months and did not have
lower back pain were recruited as healthy controls.
Methods: PPT was measured in 23 spinal bone segments using a PPT
device, and the CLBP group was subjected to a pain level test (NRS) and
a psychological test using the Korean version of the Pain Catastrophizing
Scale (KPCS). The functional level was assessed using the Korean version
of the Oswestry Disability Index (KODI).
Results: PPTs of the spinal sclerotomes were significantly lower in
patients with CLBP than in healthy participants. In the CLBP group, the
composite score of lumbar PPTs showed a high correlation with the
composite scores for all segments, but not with the pain level (NRS),
KPCS score, and spinal sclerotome PPT. Moreover, PPT in the sacral
sclerotomes showed a significant negative correlation coefficient with
function, with a KODI score of -.462 (p<.01).
Conclusion: In this study, PPTs in patients with CLBP were
significantly lower than those in healthy individuals in all spinal segments
including the lumbar region. PPT in the lumbar segment was significantly
correlated with PPT in other spinal regions. The findings in this study can
be used as a reference for future clinical research on central sensitization
in patients with CLBP.
