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.

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 will check if an artificial intelligence (AI) system can accurately measure facial paralysis in people with Bell's palsy. Currently, doctors use subjective scales that can vary between observers. The AI analyzes facial movements using a camera and compares its scores to the standard clinical method. If successful, this could lead to more consistent and objective monitoring of recovery.

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

Inclusion Criteria: * Patients with unilateral Bell's palsy. * Patients must be within one month of onset of Bell's palsy symptoms at the time of enrollment. * Body mass index (BMI) less than 30 $kg/m\^2$. * Patients must be cooperative and able to follow simple verbal instructions during facial movement tasks. Exclusion Criteria: * Bilateral facial paralysis or recurrent Bell's palsy. * Facial nerve palsy due to known secondary causes (e.g., trauma, neoplasm, infection, stroke, Ramsay Hunt syndrome, or otitis media). * Facial deformities, scars, or burns that interfere with facial motion detection. * Uncooperative or cognitively impaired individuals unable to follow instructions or maintain required facial postures.
