Design outcomes

Primary

MeasureTime frameDescription
Numeric Pain Rating Scale (NPRS) - Cohort 1Up to 5 monthsTo characterize the effect of different programmed settings on pain relief. The NPRS will be recorded once or daily over a period of time, where the subjects will rate their pain on a 11-point numeric rating scale of 0 to 10, with 0 representing 'No Pain' and 10 representing 'Worst pain imaginable'. The average overall NPRS pain score prior to the scheduled visit will be used for analysis.
Numeric Pain Rating Scale (NPRS) - Cohort 2Up to 2 monthsTo characterize the effect of different programmed settings on pain relief. The NPRS will be recorded once or daily over a period of time, where the subjects will rate their pain on a 11-point numeric rating scale of 0 to 10, with 0 representing 'No Pain' and 10 representing 'Worst pain imaginable'. The average overall NPRS pain score prior to the scheduled visit will be used for analysis.
Numeric Pain Rating Scale (NPRS) - Cohort 3Up to 3 monthsTo characterize the effect of different programmed settings on pain relief. The NPRS will be recorded once or daily over a period of time, where the subjects will rate their pain on a 11-point numeric rating scale of 0 to 10, with 0 representing 'No Pain' and 10 representing 'Worst pain imaginable'. The average overall NPRS pain score prior to the scheduled visit will be used for analysis.
Numeric Pain Rating Scale (NPRS) - Cohort 4Up to 5 monthsTo characterize the effect of different programmed settings on pain relief. The NPRS will be recorded once or daily over a period of time, where the subjects will rate their pain on a 11-point numeric rating scale of 0 to 10, with 0 representing 'No Pain' and 10 representing 'Worst pain imaginable'. The average overall NPRS pain score prior to the scheduled visit will be used for analysis.
Numeric Pain Rating Scale - Cohort 5Up to 5 monthsTo characterize the effect of different programmed settings on pain relief. The NPRS will be recorded once or daily over a period of time, where the subjects will rate their pain on a 11-point numeric rating scale of 0 to 10, with 0 representing 'No Pain' and 10 representing 'Worst pain imaginable'. The average overall NPRS pain score prior to the scheduled visit will be used for analysis.
Numeric Pain Rating Scale (NPRS) - Cohort 6Up to 7 monthsTo characterize the effect of different programmed settings on pain relief. The NPRS will be recorded once or daily over a period of time, where the subjects will rate their pain on a 11-point numeric rating scale of 0 to 10, with 0 representing 'No Pain' and 10 representing 'Worst pain imaginable'. The average overall NPRS pain score prior to the scheduled visit will be used for analysis.
Numeric Pain Rating Scale (NPRS) - Cohort 7Up to 8 monthsTo characterize the effect of different programmed settings on pain relief. The NPRS will be recorded once or daily over a period of time, where the subjects will rate their pain on a 11-point numeric rating scale of 0 to 10, with 0 representing 'No Pain' and 10 representing 'Worst pain imaginable'. The average overall NPRS pain score prior to the scheduled visit will be used for analysis.
Numeric Pain Rating Scale (NPRS) - Cohort 8Up to 0.5 monthsTo characterize the effect of different programmed settings on pain relief. The NPRS will be recorded once or daily over a period of time, where the subjects will rate their pain on a 11-point numeric rating scale of 0 to 10, with 0 representing 'No Pain' and 10 representing 'Worst pain imaginable'. The average overall NPRS pain score prior to the scheduled visit will be used for analysis.
Numeric Pain Rating Scale at Enrollment (NPRS) - Cohort 9Up to 1 monthTo characterize the effect of different programmed settings on pain relief. The NPRS will be recorded once or daily over a period of time, where the subjects will rate their pain on a 11-point numeric rating scale of 0 to 10, with 0 representing 'No Pain' and 10 representing 'Worst pain imaginable'. The average overall NPRS pain score prior to the scheduled visit will be used for analysis.

Outcome results

Primary

Numeric Pain Rating Scale at Enrollment (NPRS) - Cohort 9

To characterize the effect of different programmed settings on pain relief. The NPRS will be recorded once or daily over a period of time, where the subjects will rate their pain on a 11-point numeric rating scale of 0 to 10, with 0 representing 'No Pain' and 10 representing 'Worst pain imaginable'. The average overall NPRS pain score prior to the scheduled visit will be used for analysis.

Time frame: Up to 1 month

Population: Number analyzed refers to patients with measure available.
