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
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 This study
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 Results may not be published yet.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

Summary

This study tested whether using ultrasound during a nerve test (electroneuromyography) can reduce the electrical stimulation needed, making the test less painful. 290 adults were randomly assigned to receive the test with or without ultrasound guidance. The goal was to see if ultrasound helps find the best spot for stimulation, lowering discomfort while still getting accurate results.

What this could mean

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

Active substance
ultrasound guidance during electroneuromyography
What this could lead to
If it works, this could make nerve tests less uncomfortable for patients by using ultrasound to find the best spot for stimulation.
What could go wrong
This is a completed study, but the benefit may be small or not apply to all patients. The intervention is about comfort, not treating a disease.

Inclusion Criteria: * Patient requiring an electroneuromyogram whose indication allows the application of a standard protocol of examination. * Patient that has given his/her free and informed consent. * Patient that signed the consent form. * Patient with an health insurance plan. * The patient is at least 18 years old (≥). * he patient is under 80 years old (≤). Exclusion Criteria: * Patient with symptoms of neuropathy during the screening. * Patient whose Neurological severity score (NSS) score is ≥ 3. * Patient whose neurological examination is abnormal and suggestive of neuropathy. * Patient presenting a pathology that could cause neuropathy (e.g. diabetes, renal failure, etc.). * Patient already participating in a category 1 research study (Jardé law). * Patient in an exclusion period determined by another study. * Patient under the protection of justice, under guardianship or under curatorship. * Patient refusing to sign the consent form. * Patient for which it is impossible to provide information about the study. * Pregnant patient, parturient, or breastfeeding.
