Quantifying Pain: A Validated Approach to Assessing Pain Perception 

The objective of this webinar is to address the need for a better way of measuring heat pain perception, especially in relation to assessment of opioid induced hyperalgesia and other chronic pain disorders. In this session, a longstanding method with population derived normative values provides which meets this need, will be introduced.

Learning Objectives:

  • To discuss use of the CASE IV system in prospective research involving adults with chronic pain with an emphasis on measuring alterations in HP perception attributed to opioid induced hyperalgesia.
  • To explain the testing methodology used in this research to determine heat pain (HP) perception.
  • To provide information about the three key parameters of heat pain perception including HP 0.5, HP 5 and HP 5-0.5 and the value of using these parameters.
  • To demonstrate the advantages of using a robust reporting system with regard to generating standardized scores of HP perception based on population derived normative values.
