To observe the distribution characteristics and rules of pain sensitivity points on body surface in patients with knee osteoarthritis (KOA).
A total of 916 patients with KOA were selected in this study, the pain sensitivity points of local site of knee joint were probed by thumb palpation. Tape was used to measure the distance between the pain sensitivity points and the most nearby acupoints. The Wagner tenderness measuring instrument was used to measure the tenderness threshold of pain sensitivity points.
A total of 3618 pain sensitivity points were probed, among them, 3338 pain sensitivity points were sensitized. The minimum sensitization degree was 1.00, the maximum sensitization degree was 3.39, while the average sensitization degree was (2.16±0.60). Pain sensitivity points were distributed 0.37-1.73 around the acupoints, the average distance was (1.26±0.20) . Most of the pain sensitivity points (48.7%) were around Yingu (KI 10), Ququan (LR 8) and Xuehai (SP 10). The number and sensitization degree of pain sensitivity points were associated with McGill pain questionnaire score of patients with KOA (<0.001).
The pain sensitivity points of patients with KOA may be the expansion effect of acupoint areas in the disease states, pain sensitivity points are more likely to appear on the medial side of knee joint.
观察膝骨关节炎（KOA）患者体表疼痛敏化点的分布特征及规律。
本研究共纳入916例KOA患者，采用拇指触诊法探寻膝关节局部的疼痛敏化点。用卷尺测量疼痛敏化点与最近穴位之间的距离。采用瓦格纳压痛测量仪测量疼痛敏化点的压痛阈值。
共探寻到3618个疼痛敏化点，其中3338个疼痛敏化点出现敏化。敏化程度最小值为1.00，最大值为3.39，平均敏化程度为（2.16±0.60）。疼痛敏化点分布在穴位周围0.37 - 1.73处，平均距离为（1.26±0.20）。大部分疼痛敏化点（48.7%）位于阴谷（KI 10）、曲泉（LR 8）和血海（SP 10）周围。疼痛敏化点的数量及敏化程度与KOA患者的麦吉尔疼痛问卷评分相关（<0.001）。
KOA患者的疼痛敏化点可能是疾病状态下穴位区域的扩展效应，疼痛敏化点更易出现在膝关节内侧。
