2021年2月15日 更新者：Amol Soin、Kettering Health Network
Multi-Center Evaluation of Clinical Outcomes of Pulse Widths <500 μsec and >1000 μsec During a Temporary Spinal Cord Stimulation Trial
The purpose of this study is to evaluate the effect of pulse widths <500 μsec and >1000 μsec on clinical outcomes during a temporary SCS trial.
研究概览
详细说明
The proposed study is a prospective, multi-center, two-arm, randomized, crossover design to be conducted at up to 10 sites.
The study will enroll up to 100 subjects in order to include up to 10 subjects in the study per site.
Subjects selected to participate in the trial have back and/or leg pain, have been evaluated as a candidate for SCS and have agreed to undergo a temporary SCS trial using the Algovita® system with percutaneous leads.
Each subject will be followed during the trial period of approximately 7+/-2 days.
The study will end when the last subject has completed the trial period and exited.
The expected enrollment period for this study is approximately six months.
After exit from the clinical study, subjects will continue to be followed by their physician per usual care.
All device and procedure-related AEs will be collected and reported per the study protocol.
