With the advent of rechargeable internal neural stimulators (rINS) for deep brain stimulation, our aim was to survey patient satisfaction and clinical efficacy in an early cohort of patients receiving this new technology. ⋯ Most patients were happy with their rechargeable internal neural stimulator. A reduction in efficacy was noticed in 22% of patients, which is similar to the proportion of patients noticing a reduction in efficacy when replacing with a non-rechargeable system. Thus, all patients require close monitoring post-replacement of rINS, in case possible adjustment of parameters is required.

Deep brain stimulation (DBS) is an effective modality of treating cardinal motor symptoms of several movement disorders such as Parkinson's disease, essential tremor, and dystonia. Although hardware-related complications of DBS have been reported, the cosmetic satisfaction and discomfort associated with infraclavicular subcutaneous implantation of the pulse generator has not been described. The authors adopted a technique of transaxillary subpectoral implantable pulse generator (IPG) placement and investigated the difference in the discomfort, cosmetic satisfaction, mean operation time for IPG implantation, and severity of postoperative pain between infraclavicular subcutaneous placement and transaxillary subpectoral implantation of IPG. ⋯ These results demonstrated that subpectoral transaxillary IPG implantation can provide better cosmetic satisfaction in patients undergoing DBS, with less discomfort and morbidity related to erosion and infection.

To determine the inhibitory effects of pudendal nerve stimulation (5 Hz) on bladder overactivity at early and late stages of spinal cord injury in dogs. ⋯ Pudendal nerve stimulation can increase the bladder capacity and compliance only during the early period before the bladder wall becomes fibrosit and can inhibit the nonvoiding contraction during two stages.

To compare larger diameter corkscrew-tined leads with previously described intracardiac pacing leads for temporary gastric neurostimulation in a canine model. ⋯ These results suggest that the current concept of temporary gastric electrical neurostimulation via a mucosal approach must be reevaluated, as the procedure most likely does not accurately mimic electrical stimulation in the muscularis.
