Chronic pain is often difficult to explain on the basis of objective findings. Various theoretical models are available. The hypothesis advanced here is that chronic nonprogressive pain is primarily a neuropsychologic event and that it is in the same category as the emotions of anxiety and depression, with each emotional state having neurochemical correlates now achieving some definition. General systems theory and analogy are used to compare acute and chronic pain with the phenomena of fear and anxiety and also with grief and depression.
基于客观检查结果往往难以解释慢性疼痛。有多种理论模型可供参考。本文提出的假说是，慢性非进行性疼痛主要是一种神经心理事件，它与焦虑和抑郁情绪属于同一类别，现在每种情绪状态都有了一些明确的神经化学关联。运用一般系统理论和类比方法，将急性和慢性疼痛与恐惧和焦虑现象以及悲伤和抑郁现象进行比较。
