Abstract
BACKGROUND: Peripheral nerve stimulators (PNS) are currently used for refractory cases of neuralgia, and are associated with single manufacturer use. This is the first case report describing the novel scenario where a patient received 2 neuromodulation devices from 2 different manufacturers. CASE REPORT: We present a 32-year-old woman with spinal muscle atrophy type 2 who received a permanent PNS implant for chronic neuralgia. She experienced gradual treatment failure over 6 months, but continued to have pain relief with subsequent nerve blocks to the same nerves. She underwent semipermanent PNS placement to those same nerves. After the semipermanent PNS was removed, she experienced new, unexpected symptoms after trying to use her permanent PNS again. CONCLUSION: Instances of multiple PNS treating the same area in patients is likely going to be a recurring scenario. More research will be needed to document the potential effects that dual neuromodulation therapy may have. KEY WORDS: Case report, chronic pain, dual therapy, peripheral nerve stimulator
