Early outcomes with a flexible ECAP based closed loop using multiplexed spinal cord stimulation waveforms—single-arm study with in-clinic randomized crossover testing
To evaluate the performance of a closed-loop spinal cord stimulation (CL-SCS) system in reducing overstimulation compared to open-loop stimulation (OL-SCS) and to assess pain-related outcomes, specifically focusing on metrics such as patient comfort and pain relief.
Key Findings:
89.3% of subjects reported reduction in overstimulation with CL-SCS at 1 month (P < .001).
At 3 months, 86% of subjects with low-back/leg pain reported ≥50% reduction in pain.
60% of subjects preferred below-perception waveforms for therapy during at-home use.
Interpretation:
The flexible CL-SCS system effectively reduces overstimulation and improves pain relief, offering a more consistent therapy experience.
Limitations:
Single-arm study design limits generalizability; further studies with larger, diverse populations are needed.
Short follow-up period of 3 months for primary analysis may not capture long-term efficacy.
Conclusion:
The study supports the efficacy of an ECAP-based CL-SCS system in enhancing patient comfort and pain management, suggesting potential for broader clinical application.
