Objective. To evaluate the effectiveness of spinal cord stimulation using multiple independent programmable electrode selections compared to simple continuous stimulation. Design. ⋯ Conclusions. Continuous stimulation was not selected by any patient in favor of multi-stimulation or patient-controlled stimulation. This study indicates that in spinal cord stimulation the use of multiple electrodes together with advanced programmability increases paresthesia overlap, reduces pain scores, reduces revision rates, and improves patient satisfaction with spinal cord stimulation therapy.

The aim of the present study was to evaluate the efficacy of EMLA cream (containing a eutectic mixture of local anaesthetics) in controlling pain due to arteriovenous fistula cannulation in teenagers undergoing chronic haemodialysis. The study was conducted in two phases, one prospective, the other a blind randomized trial, at the Paediatric Haemodialysis service of the Paediatrics Department of Padua University, Italy. ⋯ Results showed that: (1) the visual analogue scale calls for an adequate training period; and (2) the EMLA cream might be effective in controlling cannulation-related pain but emotional factors, such as uncontrolled fear and stress, can interfere with the global efficacy of the analgesic approach.

The aims of this study were: (1) to compare two groups of patients with chronic pain conditions (work-related muscular pain, mainly low back pain, and fibromyalgia) in general coping and pain-specific coping; (2) to examine the relationship between general and pain-specific coping and, (3) to examine the influence of state-trait anxiety on general and pain-specific coping. The sample included 80 individuals (range=19-70 years; mean=47; SD=9.9), who were patients at two pain management clinics for examination of their physical and psychosocial health conditions and consideration on disability pension. The patients were asked to respond to theStrategies to Handle Stress Questionnaire, theCoping Strategies Questionnaireand theState-Trait Anxiety Inventory. ⋯ Anxiety-prone patients with fibromyalgia might benefit from psychological support in the process of coping with pain.

Study Design. This is a retrospective study on 102 patients subjected to implantation of a spinal cord stimulation system for nonmalignant chronic pain management. The study was conducted through an extensive questionnaire and telephone interviews by a neutral third party. ⋯ Psychological screening contributed to the success of the procedure. Conclusions. With proper medical and psychological screening and with demonstrated initial pain relief, spinal cord stimulation remains an effective modality in the long-term management of severe chronic pain.

This paper is an overview of the results of computer modeling of spinal cord stimulation, started ten years ago at the University of Twente, The Netherlands. Results are given of the analysis of various geometrical factors, including spinal anatomy, which influence the effect of spinal cord stimulation on nerve fiber recruitment and paresthesia coverage. ⋯ Two new electrode types are presented: the narrow bi-/tripole and the transverse tripole. The latter also enables adjusting the body area affected with paresthesia by means of a dual channel pulse generator giving simultaneous pulses, thereby limiting surgical interventions for electrode repositioning.
