A break from pain! Interruption management in the context of pain

Activity interruptions, namely temporary suspensions of an ongoing task with the intention to resume it later, are common in pain. First, pain is a threat signal that urges us to interrupt ongoing activities in order to manage the pain and its cause. Second, activity interruptions are used in chronic pain management. However, activity interruptions by pain may carry costs for activity performance. These costs have recently started to be systematically investigated.We review the evidence on the consequences of activity interruptions by pain for the performance of the interrupted activity. Further, inspired by literature on interruptions from other research fields, we suggest ways to improve interruption management in the field of pain, and provide a future research agenda.status: Published onlin

Operant learning theory in pain and chronic pain rehabilitation

The application of operant learning theory on chronic pain by Fordyce has had a huge impact on chronic pain research and management. The operant model focuses on pain behaviors as a major component of the pain problem, and postulates that they are subject to environmental contingencies. The role of operant learning in pain behaviors generally has been supported by experimental studies, which are reviewed in the present article. Subsequently, the rationale, goals, and methods of operant behavioral treatment of chronic pain are outlined. Special attention is paid to three therapeutic techniques (graded activity, activity pacing, and time-contingent medication management), which are discussed in detail with regard to their operationalization, effectiveness, and (possible) mechanisms of action. Criticisms of the operant model are presented, as are suggestions for the optimization of (operant) behavioral treatment efficacy
