Clinical Trial Summary

The purpose of this research is to gather post-market data regarding the effectiveness of the SPRINT Peripheral Nerve Stimulation (PNS) System for the treatment of chronic shoulder pain due to chronic degenerative changes of your shoulder. The System delivers mild electrical stimulation to the muscles in your shoulder. The System includes up to two leads (small wires) that are placed through your skin into your shoulder. The leads attach to a device worn on your body that deliver stimulation (called a Stimulator). The device is cleared by the FDA for up to 60 days of use for the relief of chronic or acute pain.

Description:

Background Chronic degenerative changes in the shoulder are a frequent source of debilitating chronic pain. In particular, osteoarthritis of the shoulder has been estimated to affect up to 32.8% of the adult population over the age of 60, and OA in general is one of the most frequent causes of disability in the United States.1 OA impacts the quality of life of tens of millions of Americans and carries a significant economic burden of over $60 billion in the U.S. each year.2 Degenerative joint disease in the shoulder is commonly managed with physical therapy and over-the-counter medications, but these modalities can be insufficient for pain management as degeneration progresses.3 Corticosteroid injections, radiofrequency ablations, and even partial or total shoulder arthroplasty are used to treat advanced cases3, and these interventions often either have limited long-term effectiveness or are associated with significant invasiveness or other side effects and complications. Peripheral nerve stimulation (PNS) is a neuromodulatory technique that seeks to provide pain relief through stimulation of the nerves that innervate the shoulder (e.g., the suprascapular nerve and axillary nerve). A novel, 60-day percutaneous PNS system that is FDA-cleared has shown effectiveness for chronic shoulder pain following stroke and shoulder impingement syndrome4-15, and has demonstrated the potential to provide sustained relief following the short-term, 60-day treatment.8, 15-18 The mechanism of action of neuropathic pain in osteoarthritis is proposed to be via peripheral sensitization (e.g., axillary and suprascapular nerves) that leads to subsequent upstream hypersensitization of the central nervous system; the proposed mechanism of long-term pain relief with 60-day PNS via reconditioning of the CNS to reverse hypersensitization therefore suggests that the treatment may be effective for degenerative shoulder including OA.19, 20 However, no study has prospectively evaluated the use of 60-day, percutaneous PNS for the treatment of debilitating pain associated with degenerative changes in the shoulder. The goal of this study is therefore to collect data on the use of 60-day PNS for the treatment of chronic pain associated with degenerative shoulder. Objectives The study objective is to gather post-market data regarding the effectiveness of the SPRINT PNS System for the treatment of chronic shoulder pain due to degenerative changes of the shoulder.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Reduction in average pain and/or reduction in pain interference	Average pain intensity is measured using the PROMIS-29 v2.0 profile. The measure assesses pain intensity using a single 0-10 numeric rating scale. Average pain interference is measured using Brief Pain Inventory--Short Form Question #9 (BPI-9). BPI-9 uses a 0-10 numeric rating scale across seven health domains (physical function, fatigue, pain interference, depressive symptoms, anxiety, ability to participate in social roles and activities, and sleep disturbance.)	3 months
Secondary	Changes in pain intensity	Changes in pain intensity will be assessed using the PROMIS-29 v2.0 profile. The measure assesses pain intensity using a single 0-10 numeric rating scale.	1 year
Secondary	Changes in pain interference	Changes in average pain interference are measured using Brief Pain Inventory--Short Form Question #9. The measure assesses pain interference using a 0-10 numeric rating scale across seven health domains (physical function, fatigue, pain interference, depressive symptoms, anxiety, ability to participate in social roles and activities, and sleep disturbance.)	1 year
Secondary	Changes in Shoulder Function	Shoulder function is measured using the Western Ontario Arthritis of the Shoulder (WOOS) index. The WOOS index is a patient-reported, disease-specific questionnaire for the measurement of the quality-of-life in patients with osteoarthritis.	1 year
Secondary	Changes in shoulder range of motion	Shoulder range of motion is measured as degrees of active range of motion (flexion, abduction, internal rotation, and external rotation) based on physical examination.	1 year
