About this study
Official title: A Post-Market Observational Case Series Study of Percutaneous Peripheral Nerve Stimulation (PNS) for the Treatment of Chronic Shoulder Pain
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.
Read the detailed 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Subjects That Experienced ≥30% Reduction in Average Shoulder Pain Intensity
All subjects completed PROMIS-29 Profile v.21 and BPI-9 at Baseline and at 3-months after the start of treatment. Average pain intensity is measured using the 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). Average pain interference was calculated utilizing PROMIS-29. The average score for the PROMIS-29 pain interference assessment for the general population in the United States is 50, with a standard deviation of 10. The raw score for pain interference ranges from 4 to 20. Higher scores on PROMIS measures indicated more of the concept being measured. For example, a score of 60 is one standard deviation above the average population.
Measured: 3 months
Secondary outcomes (3)
Percent Change in Pain Interference Score
Changes in average pain interference are measured using PROMIS-29 v2.1, Pain Interference domain. This domain includes four questions intended to capture a patient's ability to function in daily life living with pain. Questions assess pain interference with: day to day activities, work around the home, social activities, and household chores. Patients report the degree of pain interference via five-point Likert scale, from "Not at all" to "Very much." A positive change would indicate an increase in pain interference in activities of daily living from baseline, while a negative change would indicate a decrease in pain interference.
Measured: 3 months
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.
Measured: 1 year
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.
Measured: 1 year

Questions about this trial
What is this clinical trial studying?
An observational study of Shoulder Pain and Shoulder Injuries, run by International Spine, Pain and Performance Center at 2 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 6 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 6 Nov 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Subjects That Experienced ≥30% Reduction in Average Shoulder Pain Intensity (time frame: 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05649917, which also lists 20 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Nov 2026.
