Abstract
OBJECTIVE: To observe the distribution characteristics and rules of pain sensitivity points on body surface in patients with knee osteoarthritis (KOA). METHODS: 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. RESULTS: <0.001). CONCLUSION: 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.
