OBJECTIVE
To assess the usefulness of a pressure algometer to measure pressure pain threshold (PPT) for diagnosis of myofascial pain syndrome (MPS) in the upper extremity and trunk muscles.
METHOD
A group of 221 desk workers complaining of upper body pain participated in this study. Five physiatrists made the diagnosis of MPS using physical examination and PPT measurements. PPT measurements were determined for several muscles in the back and upper extremities. Mean PPT data for gender, side, and dominant hand groups were analyzed. Sensitivity and specificity of Fischer's standard method were evaluated. PPT cut-off values for each muscle group were determined using an ROC curve.
RESULTS
Cronbach's alpha for each muscle was very high. The PPT in men was higher than in females, and the PPT in the left side was higher than in the right side for all muscles tested (p<0.05). There was no significant difference in PPT for all muscles between dominant and non-dominant hand groups. Diagnosis of MPS based on Fischer's standard showed relatively high specificity and poor sensitivity.
CONCLUSION
The digital pressure algometer showed high reliability. PPT might be a useful parameter for assessing a treatment's effect, but not for use in diagnosis or even as a screening method.
目的
评估压力痛觉计测量上肢和躯干肌肉肌筋膜疼痛综合征（MPS）压力疼痛阈值（PPT）的有效性。
方法
一组221名主诉上身疼痛的办公室职员参与了本研究。5名物理治疗师通过体格检查和PPT测量对MPS进行诊断。测定背部和上肢几块肌肉的PPT。分析了性别、左右侧和优势手组的平均PPT数据。评估了费舍尔标准方法的敏感性和特异性。使用ROC曲线确定每个肌肉组的PPT临界值。
结果
每块肌肉的克朗巴哈系数都非常高。所有测试肌肉中，男性的PPT高于女性，左侧的PPT高于右侧（p<0.05）。优势手组和非优势手组所有肌肉的PPT无显著差异。基于费舍尔标准对MPS的诊断显示出相对较高的特异性和较差的敏感性。
结论
数字压力痛觉计显示出高可靠性。PPT可能是评估治疗效果的有用参数，但不适用于诊断甚至作为筛查方法。
