What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

Stanford University is testing a wearable ultrasound device that targets peripheral nerves to reduce chronic pain. The device is placed on the skin over the painful area and delivers focused ultrasound waves. In this early study, 90 adults with nerve-related pain will attend a single visit to test safety and pain relief. The goal is to see if this non-invasive approach could become a practical, drug-free pain management tool.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
ultrasound device
What this could lead to
If it works, this could offer a non-invasive, drug-free option for managing chronic nerve pain.
What could go wrong
This is a very early study with only 90 participants and a single visit. It primarily checks safety, not long-term effectiveness, and may not work for everyone.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 90 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Jun 2026

An estimate. Start dates often move.

Expected to finish

Jun 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Stated willingness to comply with all study procedures and availability for the duration of the study 2. Persons aged 18 and older. 3. In good general health as evidenced by medical history 4. Chronic pain located in the distribution of any of the target nerves of interest, including the occipital, suprascapular, median, femoral/leg, stellate ganglion/vagus nerves, neuroma, or amputees. Exclusion Criteria: * Patients with compromised skin integrity for whom device placement would result in increased risk of harm (such as those with extensive burns, active dermatologic conditions, or wounds that would prevent safe device placement) * Pregnant patients, as the devices have not been validated in this population * Additionally, the treating clinician may exclude any patient if they determine that study participation would be inappropriate for the patient's clinical condition.
