Intrathecal administration of opioids is a very efficient tool in the long-term control of intractable nonmalignant pain. However, despite the well known role of opioids in endocrine regulation, few data are available about possible effects on hypothalamic-pituitary function during this treatment. Seventy-three patients (29 men and 44 women; mean age, 49.2(More)
STUDY DESIGN Systematic review. OBJECTIVES To assess efficacy and safety of spinal cord stimulation in patients with chronic leg and back pain and failed back surgery syndrome and to examine prognostic factors that predict spinal cord stimulation outcome. SUMMARY OF BACKGROUND DATA A previous systematic review of spinal cord stimulation in patients with(More)
OBJECTIVE The objective of this prospective, open-label, multicenter European clinical trial was to quantify the efficacy and safety of a spinal cord stimulation (SCS) system that utilizes high-frequency (up to 10 kHz) waveforms, which do not produce paresthesia, for the treatment of chronic, intractable pain of the back and/or limbs. MATERIAL AND METHODS(More)
Spinal cord stimulation (SCS) is an effective technique for the relief of neuropathic pain. Biologic complications are more prevalent within the first 3 months after implantation, are generally minor and reversible, and do not affect patients' acceptance of the treatment. Technically, hardware-related complications are uncommon and occur more frequently in(More)
OBJECTIVE The aim of this study was to investigate the long-term efficacy and safety of paresthesia-free high-frequency spinal cord stimulation (HF10 SCS) for the treatment of chronic, intractable pain of the low back and legs. DESIGN Prospective, multicenter, observational study. METHOD Patients with significant chronic low back pain underwent(More)
In this systematic review, we identified and evaluated studies of the cost effectiveness of spinal cord stimulation (SCS) for the treatment of chronic pain. Published reports were identified from a systematic search of a number of general medical electronic databases (Medline, CINAHL, and EMBASE), and specialist economic databases (NHS Centre for Reviews(More)
OBJECTIVES This multicenter prospective trial was conducted to evaluate the clinical performance of a new neurostimulation system designed to treat chronic pain through the electrical neuromodulation of the dorsal root ganglia (DRG) neurophysiologically associated with painful regions of the limbs and/or trunk. MATERIALS AND METHODS Thirty-two subjects(More)
Spinal cord stimulation is a minimally invasive mode of treatment in the management of certain forms of chronic pain that do not respond to conventional pain therapy. Several authors have reported encouraging findings with this technique. Over a 10-year period in a single centre, 254 patients were subjected to a trial period of spinal cord stimulation with(More)
OBJECTIVE To review the clinical and cost-effectiveness of spinal cord stimulation (SCS) in the management of patients with complex regional pain syndrome (CRPS) and identify the potential predictors of SCS outcome. DESIGN Systematic review of the literature and meta-regression. METHODS Electronic databases were searched for controlled and uncontrolled(More)
Although opioid therapy has been accepted for the treatment of patients with cancer pain, its use for nonmalignant pain is still regarded as controversial due to concerns about the development of tolerance and psychological dependence. However, recent studies indicate that there is a low incidence of addiction in patients who do not have a history of(More)
