Novel Stimulation Patterns to Improve the Effectiveness of Spinal Cord Stimulation
Ashwin Viswanathan
Summary
The goal of this study is to compare pain outcomes achieved by spinal cord stimulation (SCS) using time varying stimulation patterns with pain outcomes achieved by current standard of care SCS.
Description
The researchers will conduct a traditional exploratory feasibility study using an investigational device to compare the clinical outcomes using time varying pulse (TVP) waveforms against time-invariant pulse (TIP) waveforms using both paresthesia and paresthesia-free SCS therapies. The therapy longevity of TVPs and TIPS will also be evaluated by tracking therapy efficacy through a long-term follow-up phase, using multiple pain assessments and at-home digital data collection.
