[Is pain therapy just an ethical-behavioral problem?].
Pain is a subjective sensation caused not only by pathological events which trigger signals perceived as algogenic (sensory component), but also by emotional mechanisms and critical assessments which modify its perception, both quantitatively and qualitatively. Therefore pain is an unique and unrepeatable experience resulting from the interaction of these three components. When faced with a patient suffering pain, it is fundamental to establish the respective quantitative incidences of these three components, in order to define the correct therapy of the pain in its totality. Whereas there are numerous therapies for dealing with the sensory component, the same cannot be said of the emotional and critical elements. We therefore suggest a number of guidelines for tackling the problem and for developing therapeutic strategies. In the literature there are few perspective and randomized studies that may evaluate the real effectiveness of the different treatments; it follows that the tested and accepted by scientific community therapeutical protocols are very few. Only recently some studies that intend to evaluate the different therapeutical strategies in connection with the different algesic syndromes are being published in the most important scientific journals.
