Accelerometer Based Objective Clinical Outcomes of Spinal Cord Stimulation (SCS) and Peripheral Nerve Stimulation (PNS)

Study Overview
=================
Brief Summary
-----------------
This study is a single site, prospective, observational trial utilizing a wrist-worn accelerometer to evaluate clinical outcomes of SCS and PNS in the treatment of chronic pain.

Detailed Description
-----------------
Up to 150 evaluable subjects will be recruited at this site on an ongoing basis. Evaluable subjects are defined as subjects that complete the End of Study visit. Each subject will be assigned an accelerometer and have data recorded for a seven-day period pre-implant trial to collect baseline data. The accelerometer will also be worn during the trial for a period of up to seven (7) days. If the trial is successful and the subject is implanted, the subject will wear the accelerometer for a seven-day period at least six (6) weeks post-permanent implant. The following assessments will be administered to subjects at the baseline (pre-implant trial) visit, the end of implant trial visit and the end of study visit (8 weeks post-permanent implant): the Numerical Rating Scale (NRS) 11-point scale for pain; the SF-36 Health Survey; the Oswestry Disability Index (ODI). Subjects treated for neck pain will also complete the Neck Disability Index (NDI). Additionally, the subjects will be asked to complete a subject diary to record average daily NRS scores for days the accelerometer is worn.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Assess whether there is an increase in objective measurements of physical function in subjects after treatment with an FDA-approved spinal cord stimulation device (SCS) or FDA-approved peripheral nerve stimulation (PNS) device compared with pre-implant. | A subject is considered to have met the primary objective if there is a statistically significant (p value < .05) increase in physical function. | Pre-implant to 8 weeks post permanent implant | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Determine if an increase in physical function obtained from objective assessments of data recorded by the wrist-worn accelerometer in subjects correlate with an improvement in subjective assessments as measured by the Numeric Rating Scale (NRS). |  | Pre-implant to 8 weeks post permanent implant | 
| Determine if an increase in physical function obtained from objective assessments of data recorded by the wrist-worn accelerometer in subjects correlate with an improvement in subjective assessments as measured by the Short Form-36 Health Survey (SF-36). |  | Pre-implant to 8 weeks post permanent implant | 
| Determine if an increase in physical function obtained from objective assessments of data recorded by the wrist-worn accelerometer in subjects correlate with an improvement in subjective assessments as measured by the Oswestry Disability Index (ODI). |  | Pre-implant to 8 weeks post permanent implant | 
| Determine if an increase in physical function obtained from objective assessments of data recorded by the wrist-worn accelerometer in subjects correlate with an improvement in subjective assessments as measured by the Neck Disability Index (NDI). |  | Pre-implant to 8 weeks post permanent implant |
