Quantitative Sensory Testing in pain assesment and treatment. Brief review and algorithmic management proposal. / Test sensitivos cuantitativos («Quantitative Sensory Testing¼) en el diagnóstico y tratamiento del dolor. Breve revisión y propuesta de protocolización de empleo.

ABSTRACT

Quantitative Sensory Testing (QST) is used to globally analyze the nociceptive system in order to obtain a more objective understanding of pain perception. In recent years, QST has become a common tool in many pain clinics and anesthesiology departments worldwide. In 2013, the Neuropathic Pain Special Interest Group of the IASP put forward the first recommendations for conducting QST in clinical practice and research. However, the wide variety of QST methodologies and standards in the literature make it difficult to generalize the used of this tool in clinical practice. In this study, we present the basic concepts of QST, the type of tests and devices used, how they are applied, and the role of QST in anesthesiology and pain management.
