背景：手动压力触诊是一种用于肌筋膜疼痛综合征（MPS）和纤维肌痛（FM）分类的检查技术。目前，还没有经过验证的结果分类系统。一个有效和可靠的压痛阈值量表（PPTS）可以为临床医生提供一种方法来分级，记录和报告结果。本研究的目的是在诊断为MPS和FM的个体中验证PPTS。评估者内信度、同时效度、最小截止值和患者反应。帕拉;&帕拉;研究方法：符合入选标准的84名参与者被分为三组，每组28名（N= 84）：MPS、FM和无症状对照组。所有的参与者都进行了两部分的测试会议，使用美国流变学学院的标准分类FM。第1部分包括使用数字压力传感器进行手动触诊以确保压力一致性，第2部分包括痛觉测量。对于每个压痛点（共18个），参与者使用视觉模拟量表（VAS）对压痛进行分级，而检查员同时使用五点PPTS对反应进行分级。结果：PPTS具有良好的评定者内信度（ICC >= 88）。使用数字压力传感器和痛觉计的所有组的PPTS和VAS之间存在中度至极好的关系（rho >= .61）。PPTS的最小截止值2将MPS和FM参与者与无症状对照区分开来。讨论：结果提供了初步证据，验证个人与MPS和FM的PPTS。未来的研究应进一步研究PPTS与其他慢性疼痛和骨科疾病的临床特征。
Background: Manual pressure palpation is an examination technique used in the classification of myofascial pain syndrome (MPS) and fibromyalgia (FM). Currently, there are no validated systems for classifying results. A valid and reliable pressure pain threshold scale (PPTS) may provide a means for clinicians to grade, document, and report findings. The purpose of this investigation was to validate a PPTS in individuals diagnosed with MPS and FM. Intra-rater reliability, concurrent validity, minimum cut-off value, and patient responses were evaluated.& para;& para;Methods: Eighty-four participants who met the inclusion criteria were placed into three groups of 28 (N= 84): MPS, FM, and asymptomatic controls. All participants underwent a two-part testing session using the American College of Rheumatology criteria for classifying FM. Part-1 consisted of manual palpation with a digital pressure sensor for pressure consistency and part 2 consisted of algometry. For each tender point (18 total), participants graded tenderness using the visual analog scale (VAS) while the examiner concurrently graded response using a five-point PPTS.& para;& para;Results:The PPTS had good intra-rater reliability (ICC >= 88). A moderate to excellent relationship was found between the PPTS and VAS for all groups with the digital pressure sensor and algometer (rho >= .61). A minimum cut-off value of 2 on the PPTS differentiated participants with MPS and FM from asymptomatic controls.& para;& para;Discussion: The results provide preliminary evidence validating the PPTS for individuals with MPS and FM. Future research should further study the clinimetric properties of the PPTS with other chronic pain and orthopedic conditions.
