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

Terminated

• Conditions: Back Pain; Neck Pain; Chronic Pain

• Registration Number: NCT02948049
• Lead Sponsor: Holy Cross Hospital, Florida

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.

Study & Design

• Study Type: OBSERVATIONAL
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
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.	Pre-implant to 8 weeks post permanent implant	A subject is considered to have met the primary objective if there is a statistically significant (p value \< .05) increase in physical function.

Secondary Outcome Measures

Name	Time	Method
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
