Objective. This study aims to evaluate the usefulness of peripheral nerve stimulation as a treatment option for patients with chronic low back pain. Materials and Methods. More than 12 months, we collected data on consecutive patients who had successful trials and were subsequently implanted with octrode percutaneous leads placed subcutaneously within the major area of pain. Eleven patients met diagnostic criteria for failed back surgery syndrome. ⋯ Pain relief was highly correlated with reduced analgesia and patient satisfaction. No complications were reported. Conclusion. This study demonstrates a treatment option that is safe, nonpharmacologic, reversible, and effective for patients with chronic low back pain that have exhausted other treatment options.

Objectives. This study aims to demonstrate the utility of spinal cord stimulation in a neuropathic pain syndrome and overall decline in health and functional independence following elapid envenomation in a morbidly obese, insulin-dependent diabetic. Materials and Methods. A two-lead, 16-electrode constant-current, independently controlled system is placed in the mid-cervical spine. Results. Noted were a improvement in overall health status with better glycemic control and return to work status in response to adequate pain control. Conclusions. The case serves as a model for other orphan pain cases with a seemingly esoteric etiology and adds to the existing body of literature that spinal cord stimulation and neuromodulation, in general, has a wide-ranging applicability peripheral neuropathic pain syndromes.

Objective. This study aims to assess peripheral nerve field stimulation as a treatment option for chronic pain and test for indicators of outcome. Materials and Methods. We reviewed all patients permanently implanted with peripheral nerve field stimulators over the past 24 months. A questionnaire was used to assess outcomes. ⋯ Most patients reported decreases in analgesic use after treatment. Pain relief was significantly and highly correlated with reduced analgesic intake and patient satisfaction. Conclusion. Peripheral nerve field stimulation is a safe, reversible, and effective treatment option for patients with chronic pain, particularly those under 60 years.

Introduction. The classic presentation of ankylosing spondylitis not only impairs spinal mobility but also imposes functional limitations, and fatigue is common. Methods. We report here the outcomes of spinal cord stimulation (SCS) in the case of a 47-year-old man with low back and hip/thigh pain due to ankylosing spondylitis, with failed responses to conservative therapies aimed at treating this pain. ⋯ SCS also resulted in improved socioeconomic outcomes with a return to work. Conclusions. With further research in patients with broader presentations of the disease, SCS may prove efficacious in suppressing intractable pain symptoms due to ankylosing spondylitis, thus improving quality of life measures.

Objectives. The pain associated with herpes zoster can be classified as acute phase, persistent phase, or chronic phase, but if it is prolonged, it becomes resistant to treatment. It is clinically important to prevent transition to postherpetic neuralgia after the onset of herpes zoster, and the outcome depends on whether continuous and potent pain management can be achieved between the acute and persistent phases. We evaluated the effect of pain management leading to quick termination of pain using temporary spinal cord stimulation (SCS) which does not require implantation of a device. ⋯ Less epidural analgesia was required and the adverse reactions of lowered blood pressure in three cases and urinary retention in seven cases disappeared soon. The self-rated satisfaction was higher with SCS than with CEB in all 14 cases, because it is highly controllable and has minimal activities of daily living-lowering effects. Conclusion. Temporary SCS, which does not require implantation of a device, may have a potent analgesic effect on severe pain in patients in the persistent phase after herpes zoster, and prevent transition to postherpetic neuralgia.
