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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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 tested whether a device called MyotonPro can reliably measure the biomechanical properties of facial muscles in people with facial paralysis. Researchers compared it to standard electromyography (EMG) in 40 patients. The goal was to see if MyotonPro could be a useful tool for monitoring recovery after facial reanimation surgery.

What this could mean

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

What this could lead to
If successful, this could provide a new, non-invasive tool for doctors to track recovery of facial muscles after paralysis surgery.
What could go wrong
This is a small, completed study with only 40 participants, so results may not apply to everyone. The device is being compared to standard methods, and it may not prove more useful.

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 40 people

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

Started

Sep 2015

Finished

Apr 2019

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 75 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. unilateral peripheral facial nerve palsy 2. Mental capacity to give consent 3. The patient is able to sit independently Exclusion Criteria: 1. Adults who have undertaken strenuous exercise within the last twenty-four hours 2. Adults taking prescription medication with a known effect on the mechanical properties of muscle (e.g. benzodiazepines) or receiving antispasmodic medications (e.g. botulinum A toxin) 3. Adults with poor mobility (unable to lie prone). 4. Adults with a body mass index (BMI) \>30 kg/m2 . Muscle measurements may be inaccurate with excessive subcutaneous tissue
