The authors present a system for nomenclature and documentation of symptoms and signs associated with pain. The system was compiled in a staged process by the study group for methods and documentation of pain-associated symptoms and signs (Arbeitsgemeinschaft für Methodik und Dokumentation von Schmerzbefunden [AMDS]). The suggested items were elaborated from terms used in current national and international guidelines and classifications and in part integrated into superordinate terms. ⋯ The items for the description of pain-associated symptoms and signs are divided into the areas of algesiomotor, psychoalgesiological and somatoalgesiological findings. The aim is the documentation of a multidimensional algesiological description of findings with defined terminology, which can serve as a comparable and unified standard, particularly in the field of pain assessment. The AMDS system should enable a systematic description of pain, which is a reliable foundation for diagnostics, therapy planning and expert case evaluation.

Randomized Controlled Trial
[Neuromodulation using matrix stimulation : A treatment for acute pain?]
There is currently a lack of studies that evaluate the effects of matrix electrode neuromodulation on acute pain. In this prospective and randomized cross-over study, we investigated the efficacy of 4 Hz-matrix stimulation on venipuncture-induced pain in 30 healthy subjects. ⋯ The results of this study showed for the first time that pre-emptive matrix stimulation could be an effective way to reduce acute pain. The duration of stimulation seems to play a key role in the effectiveness of the neurophysiological mechanism of action. Matrix stimulation is a therapeutic intervention with very few side effects, which could, in the future, expand our pain-management options for the treatment of acute pain.

In 2009 the diagnosis chronic pain disorder with somatic and psychological factors (F45.41) was integrated into the German version of the International Classification of Diseases, version 10 (ICD-10-GM). In 2010 Paul Nilges and Winfried Rief published operationalization criteria for this diagnosis. In the present publication the ad hoc commission on multimodal interdisciplinary pain therapy of the German Pain Society now presents a formula for a clear validation of these operationalization criteria of the ICD code F45.41.
