Trial Outcomes & Findings for OPTIONS Spinal Cord Stimulation Programming Parameters (NCT NCT02503787)

NCT ID: NCT02503787

Last Updated: 2017-09-19

Results Overview

Self reported daily average overall pain score 5 days prior to baseline and at 3 months post device activation in subjects receiving programming options in spinal cord stimulation. The question is scored 0-10 (0=no pain; 10=pain as bad as can be).

Participant Flow

All enrolled subjects will undergo a Spinal Cord Stimulation device trial that includes an intraoperative programming trial. Subjects experiencing a positive response (improvement in average overall pain relief) during the trial will move forward with a permanent implant. Those not reporting a positive response will be exited from the study.

PRIMARY outcome

Timeframe: From baseline to 3 months post device activation

Self reported daily average overall pain score 5 days prior to baseline and at 3 months post device activation in subjects receiving programming options in spinal cord stimulation. The question is scored 0-10 (0=no pain; 10=pain as bad as can be).

SECONDARY outcome

Timeframe: From baseline to 3 months post device activation

Evaluate study subject impression of change as measured by the Patient Global Impression of Change questionnaire. The questionnaire encompasses change in ACTIVITY LIMITATIONS, SYMPTOMS, EMOTIONS, and OVERALL QUALITY OF LIFE, scored on a scale of 1-7 (1=no change or the condition has gotten worse: 7=A great deal better, and a considerable improvement that has made all the difference).
