ClinicalTrials.gov Identifier:
NCT01847885
First received: April 23, 2013
Last updated: October 13, 2016
Last verified: October 2016
  Purpose
The purpose of this study is to determine if electrical stimulation (small levels of electricity) reduces post-stroke shoulder pain. This study involves a device called the Smartpatch System. The Smartpatch System delivers mild electrical stimulation to the muscles in the shoulder. The Smartpatch System includes a small wire (called a "Lead") that is placed through the skin into the muscle of the shoulder. It also includes a device worn on the body that delivers stimulation (called the Smartpatch Stimulator).

Condition Intervention
Post-stroke Shoulder Pain
Hemiplegic Shoulder Pain
Device: Smartpatch Peripheral Nerve Stimulation (PNS) System

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Randomized, Double-Blinded, Placebo-Control Multicenter Pivotal Study of the Smartpatch Peripheral Nerve Stimulation (PNS) System for the Treatment of Chronic Post-Stroke Shoulder Pain

Primary Outcome Measures:
  • Change from Baseline Shoulder Pain Intensity at End of Treatment (EOT) [ Time Frame: Baseline, End of Treatment (4-weeks of Treatment/Control) ]
  • Device related adverse event rates in treatment and control groups [ Time Frame: 1-week ]
  • Device related adverse event rates in treatment and control groups [ Time Frame: 2-weeks ]
  • Device related adverse event rates in treatment and control groups [ Time Frame: 3-weeks ]
  • Device related adverse event rates in treatment and control groups [ Time Frame: End of Treatment (4-weeks of Treatment/Control) ]
  • Device related adverse event rates in treatment and control groups [ Time Frame: 1-week post-treatment ]
  • Device related adverse event rates in treatment and control groups [ Time Frame: 4-weeks post-treatment ]
  • Device related adverse event rates in treatment and control groups [ Time Frame: 12-weeks post-treatment ]

Secondary Outcome Measures:
  • Change from Baseline Shoulder Pain Interference at End of Treatment [ Time Frame: Baseline, End of Treatment (4-weeks of Treatment/Control) ]
  • Durability of change from baseline Shoulder Pain Intensity at 12-weeks beyond Treatment [ Time Frame: Baseline, 12-wks post-treatment ]
  • Change from Baseline Quality of Life at End of Treatment [ Time Frame: Baseline, End of Treatment (4-weeks of Treatment/Control) ]
  • Change from Baseline Average Pain Intensity at End of Treatment [ Time Frame: Baseline, End of Treatment (4-weeks of Treatment/Control) ]
  • Patient Global Impression of Change at End of Treatment [ Time Frame: End of Treatment (4-weeks of Treatment/Control) ]
  • Change in Pain Medication Usage at End of Treatment [ Time Frame: End of Treatment (4-weeks of Treatment/Control) ]
  • Clinical Global Impression of Improvement at End of Treatment [ Time Frame: End of Treatment (4-weeks of Treatment/Control) ]

Other Outcome Measures:
  • User Satisfaction with The Smartpatch System at End of Treatment [ Time Frame: End of Treatment (4-weeks of Treatment/Control) ]
    User satisfaction survey

  • User Satisfaction with The Smartpatch System at 12-weeks beyond Treatment [ Time Frame: 12-week post-treatment ]
    User Satisfaction Survey

  • Performance of the Smartpatch System at End of Treatment [ Time Frame: End of Treatment (4-weeks of Treatment/Control) ]
    Assessed through User Satisfaction Survey

  • Performance of the Smartpatch System at 12-weeks beyond Treatment [ Time Frame: 12-weeks post-treatment ]
    Assessed through User Satisfaction Survey


Estimated Enrollment: 180
Study Start Date: April 2013
Estimated Primary Completion Date: January 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Smartpatch Treatment Group
Subjects in the Treatment Group will have a Smartpatch Lead placed in the shoulder, will use the Smartpatch Peripheral Nerve Stimulation (PNS) System, and will receive electrical stimulation.
Device: Smartpatch Peripheral Nerve Stimulation (PNS) System
The Smartpatch System is an Investigation Device which delivers mild electrical stimulation to the muscles in the shoulder. The Smartpatch System includes a small wire (called a "Lead") that is placed through the skin into the muscle of the shoulder. It also includes a device worn on the body that delivers stimulation (called the Smartpatch Stimulator).
Other Name: Smartpatch System, Smartpatch
Sham Comparator: Smartpatch Control Group
Subjects in the Control Group will have a Smartpatch Lead placed in the shoulder, will use the Smartpatch Peripheral Nerve Stimulation (PNS) System, but will not receive any electrical stimulation.
