Objective: Spinal cord stimulation (SCS) is an effective method to treat therapy-resistant neuropathic pain. A new wireless SCS technology, which was introduced in recent years, promises minimal invasive SCS as well as additional advantages such as a wide range of stimulation paradigms and 3-Tesla MRI compatibility. Here, we report on our single-center experience with this new wireless SCS technology and focus our report on handling of the device as well as on potential advantages and disadvantages of wireless SCS compared to conventional SCS.

Methods: We retrospectively evaluated 12 patients suffering from therapy-resistant neuropathic pain, who were implanted with a wireless Stimwave® SCS system from 2017 to 2019. Potential issues related to handling and usability of the SCS device were evaluated from a patients’ as well as from a surgeon’s perspective. Any surgical complications were recorded. To evaluate treatment response, we assessed changes in pain ratings according to a visual analogue scale (VAS) after SCS.

Results: Mean follow-up was 228 d (95% CI, 20 d – 518 d). After an average test period of 52 d (95% CI, 11 d – 104 d), n=9/12 patients (75%) had reached pain relief greater than 50% with an average pain relief of 69.5 % (95% CI, 50.0 % – 85.0 %). On average, patients tested 2.2 different stimulation paradigms, with frequencies ranging from 60 Hz to 10kHz but there was no preferred stimulation paradigm. There were no surgical complications and no reported incidents with the 3-Tesla MRI-compatibility. N= 3/12 patients reported discomfort from wearing the SCS antenna and one patient complained about a short battery life of the controller device. Other than that, we did not record any handling issues nor did we record any relevant local discomfort associated with the implanted SCS device. Hardware complications were seen in one patient, who suffered an epidural electrode displacement.

Conclusion: Minimally invasive implantation of wireless Stimwave® SCS systems was feasible. The device offered a broader range of stimulation paradigms compared to conventional SCS devices, an allowed for a prolonged testing phase and continuous adjustment of SCS programs.
