Pain perception is a complex experience that entails somatic and psychological factors. This is especially true for chronic pain where increasing chronicity leads to a growing significance of psychological factors such as learning and memory processes or cognitive evaluation at the expense of nociceptive processes. ⋯ For the future of this research area, a differential analysis of the contribution of psychological factors to chronicity is important. For a mechanism-oriented treatment, the development of new treatment approaches and the analysis of specific subgroups for a better differential indication of treatments is needed.

Chronic and debilitating pediatric pain has a prevalence of 5% and as such constitutes a considerable health problem. The aim of this article is to provide an overview of current research activities on pediatric pain, available health care for children with chronic pain and education and training programs for health professionals. ⋯ Similar to international trends, research on chronic pediatric pain has also grown and advanced in Germany. Indeed, not only the amount of research has increased but also its scope. Nonetheless, there is clearly a need for more research efforts with regard to the understanding of (pediatric) pain mechanisms, clinical studies and, especially, investigations on health care services. It is particularly important to focus on the implementation, improvement and systematic evaluation of specialized health care services which would be available and accessible for children and adolescents with chronic pain and not be restricted to tertiary care.

Patients attend physiotherapy and physical therapy (PT) due to pain problems and/or functional impairments. Although the main focus for therapists has traditionally been physical examination and treatment of tissue structures and biomechanics, over the last few decades a growing body of research has highlighted the importance of central nervous system processing and psychosocial contributors to pain perception. Treatment with PT aims to reduce disability and suffering by reducing pain and increasing tolerance to movement. ⋯ However, there still remain substantial differences between therapists working in multidisciplinary pain clinics and those following medical referral in private practices. This article provides information on how national and international impulses have contributed to the development of different concepts of passive therapies and active/functional pain rehabilitation in Germany. In the future PT will need to provide more evidence about efficiency and modes of actions for different treatment options to selectively reason the application to patients with acute, subacute and chronic pain.

Pain research is based broadly on physiological disciplines and its development follows the methodological progress of the era, from classical psychophysiology to electrophysiological investigations at peripheral and central nociceptive systems, single cells and ion channels to modern imaging of nociceptive processing. Physiological pain research in Germany has long been part of an interdisciplinary research network extending beyond all political boundaries, and this situation has continued since molecular techniques started to dominate all biomedical research. Current scientific questions, such as intracellular nociceptive signal mechanisms, interactions with other physiological systems including the immune system, or the genetic basis of epidemic and chronic pain diseases can only be solved interdisciplinary and with international collaboration.
