Validated intruments for measuring coping in children and adolescents with chronic pain are rare in Germany. Using a sample of 180 out-patient children with chronic pain, a main component analysis was performed as well as cross-validations with out-patient and in-patient treated children. ⋯ Different alterations were found in the PPCI-R scales in children with migraine and those with tension-type headache. The PPCI revised is therefore a validated instrument for measuring coping an can be implemented e.g. in treatment studies for children suffering from chronic pain.

It has been shown that long-term treatment with opioids does not necessarily impair driving ability in patients suffering from chronic pain. However, few studies are so far available on how increases in daily opioid dosage affect driving ability. ⋯ Seven days after an increase in the daily dose of an opioid or after the initiation of opioid therapy there was no general deterioration in patients' driving ability at group level.

The results of conventional chronic back pain therapy are unsatisfactory. Deconditioning, psychosocial disorders and prolonged disability are common sequelae. ⋯ Patient selection by a health fund, interdisciplinary assessment and severity adapted treatment resulted in significant reduction in pain and functional improvement in disabled back pain patients.

Elektrophysiological methods provide objective data about the function of the somatosensory system. Broadly established methods like neurography, myography, sensory evoked potentials and electrically evoked reflexes are in contrast to less well known techniques as laser-evoked potentials and microneurography. ⋯ Unlike, laser-evoked potentials and microneurography describe the functionality of nonmyelinated, small diameter nerve fibers, which transmit pain and temperatures as sensory signals. Investigation of the sympathetic sudomotoric system can provide evidence for lesions within sympathetic nerves.
