It is important to know the factors that will influence animal models of neuropathic pain. A good reproducibility and predictability in different strains of animals for a given test increases the clinical relevance and possible targeting. An obligatory requirement for enabling comparisons of results of different origin is a meticulous definition of the(More)
UNLABELLED Transcutaneous electrical nerve stimulation (TENS) is an easy to use non-invasive analgesic intervention applied for diverse pain states. However, effects in man are still inconclusive, especially for chronic pain. Therefore, to explore the factors predicting result of TENS treatment in chronic pain we conducted a prospective, randomized,(More)
A retrospective analysis of 51 patients with cancer pain treated with a continuous i.t. morphine infusion through a tunnelled percutaneous catheter was undertaken. Because of insufficient pain relief with morphine only, 17 of these patients received a morphine/bupivacaine mixture. Pain relief subsequently improved significantly in 10 patients and a moderate(More)
The efficacy of radiofrequency lesion treatment of the cervical dorsal root ganglion (RF-DRG) in cervicobrachialgia was investigated in 61 patients by a randomized prospective double blinded study. Before lesion treatment the putative pain provoking spinal root was identified by diagnostic blocks with a local anesthetic agent. One group of patients (n = 32,(More)
In many healthy subjects, sensory thresholds for touch using Semmes-Weinstein monofilaments appear to be higher than the 2.83 filament, which some authors have suggested as a screening instrument. The currently proposed normal values, the interpretation of results, as well as the calibration of the filaments are questioned. A normative study of 20 normal(More)
OBJECTIVES Multidisciplinary treatment approaches have been found to be effective for chronic pain patients although there are large individual differences in outcomes. To increase overall treatment effects, tools are needed to identify patients most likely to benefit from tailored, comprehensive modular treatment schemes. DESIGN The present study(More)
BACKGROUND AND OBJECTIVES Selective spinal nerve infiltration blocks are used diagnostically in patients with chronic low back pain radiating into the leg. Generally, a segmental nerve block is considered successful if the pain is reduced substantially. Hypesthesia and elicited paresthesias coinciding with the presumed segmental level are used as controls.(More)
Stressful stimuli can activate the hypothalamo-pituitary-adrenal-axis and the endogenous opioid system. In addition, corticosterone and opioid release might cause analgesia. This rat study used adrenalectomy for corticosterone withdrawal and naloxone administration for opioid antagonism in order to study pain behavior and hypophyseal hormone release in the(More)
The aim of this study was to test the efficacy of shortterm transcutaneous electrical nerve stimulation (TENS) treatment in chronic pain with respect to pain intensity and patients' satisfaction with treatment results. We therefore performed a randomised controlled trial comparing TENS and sham TENS. Patients, researchers and therapists were blinded for(More)
The results obtained by percutaneous cervical cordotomy (PCC) were analysed in 43 terminally ill cancer patients treated in our institution from 1998 to 2001. We wished to determine whether there is still a place for PCC in the actual clinical situation with its wide choice of pain therapies. All patients had severe unilateral pain due to cancer, resistant(More)
