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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This study tests whether giving a mild electrical stimulation to the nerve a week before surgery can improve hand function recovery in people with severe cubital tunnel syndrome. Thirty adults with severe nerve damage will be randomly assigned to receive either real stimulation or a sham (fake) treatment before their operation. Researchers will measure nerve fiber counts and hand strength to see if the stimulation helps.

What this could mean

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

Active substance
electrical stimulation
What this could lead to
If it works, this could lead to a simple, low-cost way to boost nerve recovery after surgery for severe cubital tunnel syndrome.
What could go wrong
This is a small, early-stage trial with only 30 people, so results may not apply to everyone. The benefit may be small or not show up at all.

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 30 people

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

Started

Apr 2022

Expected to finish

Jun 2028

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 to 79 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

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. Patients aged \>18 yr, 2. If signs and symptoms of severe CuTS (ie, McGowan-Goldberg grade 3) were observed, 3. If needle EMG examination showed evidence of chronic motor axonal loss and reduced recruitment in the ulnar-innervated intrinsic hand muscles, and 4. If electrophysiologic evidence of severe motor axonal loss with motor unit number estimation (MUNE) greater than 2 standard deviations below the normative mean. Exclusion Criteria: 1\) Patients were excluded if they had concurrent nerve injury, prior surgery for CuTS or coexisting neurologic conditions
