Biofeedback is a direct feedback of a physiological function. The aim of biofeedback is to change the physiological function into a required direction. To manage this, the physiological function has to be fed back visually or acoustically and it has to be perceived consciously. ⋯ Biofeedback has proved to be successful in non-medical treatment of pain. According to more recent meta-analyses biofeedback reveals high evidence in the treatment of migraine or tension-type headache. In these headaches biofeedback procedures are considered highly effective.

The aim of this study was to investigate how sex differences affect psychological measures and coping with pain of patients with fibromyalgia. Gender differences in pain coping strategies would require different gender-specific interventions. ⋯ No gender differences were found in pain measures. Differences were found regarding psychological measures and coping strategies. Women showed more psychological strains and used more adaptive coping strategies on the scales "cognitive restructuring", "perceived self-competence", "mental diversion" and "counterbalancing activities" than men. This implies that women need more treatment for psychological aspects and men need assistance in pain management.

[Altered pain thresholds during and after opioid withdrawal in patients with chronic low back pain].
Opioids as the strongest pain drugs are often used for chronic pain although their long-term efficacy has not yet been clarified. In this longitudinal study, we compared the pain sensitivity of patients with chronic low back pain (cLBP) under long-term opioid use and treated with multidisciplinary pain therapy. ⋯ Our findings suggest that long-term use of opioids intensifies the peripheral sensitisation of cLBP. The MDPT can counteract this process.

The purpose is to clarify if comorbidity of depression reduces health-related quality of life (SF-36) in patients with chronic low back pain (CR) and if those comorbid patients (CR+DE) benefit from multimodal pain treatment. Two groups (CR and CR+DE) each with 29 patients are compared over 6 months on study days 0, 21 (inpatient) and 180 (outpatient). ⋯ The comorbid group is more severely affected by their illness, but improves very constantly. The outpatient improvement suggests a good long-term prognosis.

Neuropathic pain syndromes are characterised by the occurrence of spontaneous ongoing and stimulus-induced pain. Stimulus-induced pain (hyperalgesia and allodynia) may result from sensitisation processes in the peripheral (primary hyperalgesia) or central (secondary hyperalgesia) nervous system. The underlying pathophysiological mechanisms at the nociceptor itself and at spinal synapses have become better understood. ⋯ These mechanisms include reorganisation of cortical somatotopic maps in sensory or motor areas (highly relevant for phantom limb pain and CRPS), increased activity in primary nociceptive areas, recruitment of new cortical areas usually not activated by nociceptive stimuli and aberrant activity in brain areas normally involved in descending inhibitory pain networks. Moreover, there is evidence from PET studies for changes of excitatory and inhibitory transmitter systems. Finally, advanced methods of structural brain imaging (voxel-based morphometry, VBM) show significant structural changes suggesting that chronic pain syndromes may be associated with neurodegeneration.
