There is an ongoing debate about whether pain can be classically conditioned, but surprisingly, evidence is scarce. Here, we report 3 experiments investigating this idea. In a virtual reality task, healthy participants were approached and touched near or on their hand with a coloured pen (blue or yellow). ⋯ There was no evidence for conditioned pain in experiment 1, but there was some evidence in experiments 2 and 3. Our findings indicate that conditioned pain may exist, albeit most likely in rare cases or under specific situations. More research is needed to understand the specific conditions under which conditioned pain exists and the underlying processes (eg, response bias).

This article summarizes the many initiatives and achievements of the International Association for the Study of Pain (IASP) in pain education worldwide since 1973. These range from major events such as the World Congress on Pain that attracts thousands of attendees to the more intimate and focused Pain Schools and Pain Camps. ⋯ The unique contribution of IASP to the study of pain is reflected in its consistent focus on a biopsychosocial approach to pain, the promotion of interactions between basic scientists and clinicians, as well as multidisciplinary and interdisciplinary collaborations. Details of these rich offerings can be found on the IASP web site, and this article provides a guide for those seeking to access them.

The International Association for the Study of Pain (IASP) has become the leading professional association dedicated to promoting pain research and management. Through its many activities, including research funding, educational programs, advocacy initiatives, and global collaborations, the Association has significantly contributed to the understanding and treatment of pain. Looking into the future, the IASP is determined to continue its mission of reducing the burden of pain on individuals and societies worldwide. Here, we explore how current and past activities of the IASP will shape the future of pain research, treatment, education, and advocacy as well as provide a valuable service to its members across the world.

Historical Article
Introduction and a brief historical overview of the International Association for the Study of Pain.
The mission of the International Association for the Study of Pain (IASP) is "to bring together scientists, clinicians, healthcare providers, and policymakers to stimulate and support the study of pain and to translate that knowledge into improved pain relief worldwide." The IASP will celebrate its 50th anniversary next year, and the series of articles published in this special issue of its flagship journal PAIN highlights the IASP's achievements over the past 5 decades. This article provides a brief historical overview of the IASP's 50-year journey, including the key "players," events, and initiatives leading to its formation and contributing to its progress. It complements the other articles outlining the contributions that the IASP has made and likely will continue to make to advances in pain education, research, management and advocacy, and its value to the IASP members.

Parkinson disease (PD) affects up to 2% of the general population older than 65 years and is a major cause of functional loss. Chronic pain is a common nonmotor symptom that affects up to 80% of patients with (Pw) PD both in prodromal phases and during the subsequent stages of the disease, negatively affecting patient's quality of life and function. Pain in PwPD is rather heterogeneous and may occur because of different mechanisms. ⋯ This is also in line with the International Classification of Disease-11 , which acknowledges the possibility of chronic secondary musculoskeletal or nociceptive pain due to disease of the CNS. In this narrative review and opinion article, a group of basic and clinical scientists revise the mechanism of pain in PD and the challenges faced when classifying it as a stepping stone to discuss an integrative view of the current classification approaches and how clinical practice can be influenced by them. Knowledge gaps to be tackled by coming classification and therapeutic efforts are presented, as well as a potential framework to address them in a patient-oriented manner.
