The pain threshold was measured in patients with osteoarthrosis of the hip. The pain threshold was significantly lower in patients who required surgery than in controls. After successful surgery the threshold rose to normal levels. In patients with few or no symptoms from their osteoarthritic hips the pain threshold was high. Insensitivity to pain does not predispose towards osteoarthrosis of the hip. Indeed, the severity of symptoms can be directly related to an increased sensitivity to pain in osteoarthritic subjects.
对髋骨关节炎患者的疼痛阈值进行了测量。需要手术的患者的疼痛阈值明显低于对照组。手术成功后,阈值升至正常水平。髋骨关节炎症状较少或无症状的患者疼痛阈值较高。对疼痛不敏感并不会导致髋骨关节炎。实际上,在骨关节炎患者中,症状的严重程度可能与对疼痛的敏感性增加直接相关。
