NCT02928055

Brief Summary

The primary objective of this RCT is explore the mechanism for Hemiplegic Shoulder Pain (HSP) reduction due to treatment with peripheral nerve stimulation. We will explore the association of subject-specific clinical and demographic information and pain relief from PNS. We will explore the possible role of central sensitization mechanisms in perpetuating pain via measures of sensory and pain perception. Lastly, we will explore the dose-response association of muscle-contraction from PNS and pain reduction, completion of activities of daily living (ADLs), and improvement in quality of life.

Outcome Measures

Primary Outcomes (1)

  • Brief Pain Inventory (BPI)- Short Form (SF) Question 3 (BPI-SF3)

    Brief Pain Inventory(BPI) Short Form 3: The BPI has excellent psychometrics and is recommended for the assessment of pain in clinical trials. The developers of the BPI recommend BPI SF-3, the "pain worst" rating, as the primary response metric. The question asks participants to rate their worst pain in the prior 7-d on a 0 to 10 numeric rating scale, where "0" indicates "No pain" and "10" indicates "Pain as bad as you can imagine." A lower score is better.

    End of Treatment (EOT), EOT + 3 mo

Other Outcomes (1)

  • Adverse Events (Related)

    Electrode Implant, Start of Stimulation, 1 week after start of stimulation, 2 weeks after start of stimulation, end of treatment (EOT), EOT + 1mo, EOT + 2 mo, EOT + 3 mo

Study Arms (3)

PNS (3 hr/day)

EXPERIMENTAL

The PNS (3 hr/day) Group will receive peripheral nerve stimulation treatment for three weeks (3 hours daily) with an Intramuscular Electrical Stimulator following a one week electrode stabilization period.

Device: Peripheral Nerve Stimulation

PNS (6 hr/day)

EXPERIMENTAL

The PNS (6 hr/day) Group will receive peripheral nerve stimulation treatment for three weeks (6 hours daily) with an Intramuscular Electrical Stimulator following a one week electrode stabilization period.

Device: Peripheral Nerve Stimulation

PNS (9 hr/day)

EXPERIMENTAL

The PNS (9 hr/day) Group will receive peripheral nerve stimulation treatment for three weeks (9 hours daily) with an Intramuscular Electrical Stimulator following a one week electrode stabilization period.

Device: Peripheral Nerve Stimulation

Interventions

The stimulation system includes an external stimulator, percutaneous lead and pad. The stimulator snaps onto the pad. The pad has an embedded power source but also serves as the anode. The 1-channel stimulator outputs a biphasic current waveform with current pulse parameter ranges suitable for PNS. The percutaneous lead is inserted using an introducer (like a hypodermic needle) which is withdrawn and the lead is retained in the muscle by a barb at its tip. After a 1-week stabilization period, stimulation is initiated (daily dose is Group-dependent). Stimulus parameters may be adjusted by the research staff as deemed appropriate. The treatment period is 3 weeks after which the lead will be removed. Total time of electrode implantation is no more than 29 days.
