A visual analogue scale (VAS) and a 4-point scale (FPS) have been compared in patients suffering from prolonged constant pain due to chronic inflammatory or degenerative arthropathy. Each patient was treated with a constant low or high dose of paracetamol or dihydrocodeine throughout a four week period. The VAS was accurate, as reliable and more sensitive than the FPS in registering the intensity of chronic pain. Separate records of each estimate, sealed immediately on completion by the patient, resulted in omission of significantly more pain recordings on the FPS, whereas retention by the patients of their previous records did not systematically influence subsequent judgments. In this study, the VAS appeared to be more satisfactory than the FPS for patient self-rating of pain intensity.
在患有慢性炎症性或退行性关节病导致长期持续性疼痛的患者中，对视觉模拟量表（VAS）和四点量表（FPS）进行了比较。在四周的时间里，每位患者都接受了低剂量或高剂量的对乙酰氨基酚或二氢可待因的持续治疗。VAS在记录慢性疼痛强度方面准确、可靠且比FPS更敏感。每次评估的单独记录由患者在完成后立即密封，结果显示FPS上遗漏的疼痛记录明显更多，而患者保留其先前记录并未系统地影响后续判断。在本研究中，对于患者自我评估疼痛强度，VAS似乎比FPS更令人满意。
