背景和目的。触诊常用于腰痛患者的体格检查。本研究的目的是比较慢性腰痛（CLBP）患者和无疼痛受试者的压力疼痛检测阈值（PPDT）。研究对象和方法。从初级保健医生和物理治疗师的办公室招募了30名患有CLBP的女性受试者，并与30名没有疼痛的女性志愿者在6个部位进行了双侧PPDT测试。结果。与无疼痛的受试者相比，CLBP受试者的所有测试部位组的平均PPDT均显着降低。与无疼痛的受试者相比，CLBP受试者的整体PPDT较低(5.6 lb/cm（2) vs 6.9 lb/cm(2)）。与腰椎无关的PPDT组(5.1 lb/cm（2) vs 6.1 lb/cm(2)）和与腰椎相关的PPDT组(5.9 lb/cm（2) vs 8.0 lb/cm(2)）也是如此。讨论与结论。神经生物学或生物心理社会影响可能是CLBP患者PPDT明显降低的原因。与无疼痛的受试者相比，CLBP受试者的整体PPDT较低，在解释触诊的疼痛或压痛时应考虑到这一点。
Background and Purpose. Palpation is often utilized in the physical examination of patients with low back pain. The purpose of this study was to compare the pressure pain detection threshold (PPDT) of people with chronic low back pain (CLBP) and subjects without pain. Subjects and Methods. Thirty female subjects with CLBP were recruited from the offices of primary, care physicians and physical therapists and compared with 30 female volunteers without pain for differences in PPDT at 6 sites tested bilaterally. Results. A significantly lower mean PPDT was found for all test site groups in subjects with CLBP compared with subjects without pain. A lower global PPDT was found in subjects with CLBP compared with subjects Without pain (5.6 lb/cm(2) versus 6.9 lb/cm(2)). This also was the case for PPDT for the group of test sites unrelated to the lumbar spine (5.1 lb/cm(2) versus 6.1 lb/cm(2)) and for PPDT related to-the lumbar spine (5.9 lb/cm(2) versus 8.0 lb/cm(2)). Discussion and Conclusion. Neurobiological or biopsychosocial influences may have contributed to the lower PPDT evident in subjects with CLBP. Subjects with CLBP demonstrated a lower global PPDT compared with subjects without pain, which should be taken into account when interpreting findings of pain or tenderness from palpation.
