Introduction. Spinal cord stimulation voltage thresholds have been observed to change with body position, but previously have not been characterized in detail. Design. ⋯ Ninety-five percent of patients experienced an increase, primarily between 11 and 25%. Conclusions. These observations have implications for the design, implantation, and clinical application of spinal cord stimulators.

Objective. To examine the importance of posture on the efficacy of spinal cord stimulation in a population of chronic pain patients previously implanted with a spinal cord stimulator. Materials and Methods. ⋯ The mean range and SD of stimulation required to achieve paresthesia at all three posture levels was found to be 0.113 ± 0.062 μC for leads in the cervical region (N = 11) and 0.494 ± 0.297 μC for leads in the thoracic region (N = 19). Conclusions. To provide adequate stimulation at all postures, multiple stimulation settings (programs) would be required.

Introduction. At the present time, there is no reliable method or drug for effective relief of the severe pain caused by the amyloldotic polyneuropathy (AP). Objective. ⋯ The patient had the IT treatment for 867 days, of which 777 days (> 90%) were spent at home. Conclusion. Long-term IT administration of opioid and bupivacaine provided satisfactory long-term pain relief in a patient with refractory pain due to AP.
