What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Researchers test whether ultrasound-guided electrical stimulation of the gluteal nerves can improve hip muscle strength in people who have had low back pain. The study enrolls 24 adults with a history of low back pain and signs of gluteal muscle weakness. Participants receive electrical stimulation through a needle placed near the nerves, using higher frequencies than a standard protocol. The goal is to see if this approach increases muscle strength and control.

What this could mean

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

Active substance
ultrasound-guided percutaneous electrical stimulation of the gluteal nerves
What this could lead to
If it works, this could offer a targeted way to restore hip muscle strength after low back pain, helping people move better and reduce the chance of recurring problems.
What could go wrong
This is a small, early study with 24 people, so results may not apply broadly. The electrical stimulation can cause discomfort, and the approach requires precise needle placement under ultrasound.

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 24 people

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

Expected to start

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

Inclusion Criteria: * Patients over 18 years of age * Healthy patients at the time of inclusion selection. * Patients with a history of low back pain, without acute episodes at the time of the study. * Patients who show an alteration in the function of the gluteus maximus and gluteus medius by EMG. * Patients who show a decrease in the strength of the gluteus maximus and gluteus medius by dynamometry. * Patients who have signed the information and consent document for participation. Exclusion Criteria: * Patients with belenophobia. * Pregnant patients. * Patients with cardiac pathologies or with pacemakers that do not allow electrical stimulation. * Patients with low back pain in the acute phase. * Patients with chronic low back pain. * Patients with skin or immune disorders with contraindications for the application of invasive techniques. * Patients who refuse to sign the informed consent or to participate in the study. * Individuals who are planning a change in their lifestyle that involves a change in relation to physical activity or training.
