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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 low level laser therapy can improve facial function in people with Bell's palsy, a condition that causes sudden facial weakness. Researchers will compare laser therapy to routine physiotherapy in 100 adults aged 18 to 80. The main goal is to see if laser treatment leads to better facial movement scores.

What this could mean

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

Active substance
Low level laser therapy
What this could lead to
If it works, this could offer a new, non-invasive treatment option to help people with Bell's palsy recover facial movement faster.
What could go wrong
This is an early-stage study with only 100 participants, so results may not apply to everyone. Laser therapy might not be more effective than standard physiotherapy.

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 100 people

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

Expected to start

Oct 2025

An estimate. Start dates often move.

Expected to finish

Dec 2025

An estimate. End dates often move.

Lead sponsor

Other sponsor

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

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

Inclusion Criteria: * • A confirmed diagnosis of idiopathic facial (Bell's) palsy by a certified neurologist or Physician is required (Heckmann, Urban, Pitz, Guntinas-Lichius, \& Gágyor, 2019). * Both male and female patients, aged between 18 and 80 years (Holland \& Bernstein, 2014). * Symptom onset within the range of 72 hours to 7 days (Petruzzelli \& Hirsch, 1991). * A baseline House-Brackmann score of 2 to 4 is necessary (Bylund et al., 2021). * Availability for the entire trial duration and all subsequent follow-up visits. * Absence of any prior treatments (e.g., corticosteroids) for the current Bell's palsy episode. Exclusion Criteria: * • Alternate diagnoses that can explain Bell's palsy (e.g., Lyme disease, Ramsay Hunt syndrome) (Crouch, Hohman, Moody, \& Andaloro, 2023). * History of recurrent Bell's palsy episodes. * Presence of severe medical conditions such as uncontrolled diabetes or autoimmune disorders. * Pregnancy or lactation. Use of concurrent medications that could interfere with facial nerve function. * Exposure to LLLT in the past 3 months. * Active skin infections or lesions in the targeted treatment area. * Conditions or medications that induce photosensitivity. * Cognitive impairments that may interfere with comprehension or feedback about the trial. * Participation in another trial in the past month. * Traumatic, inflammatory, or infectious conditions including trauma, nerve root issues, metabolic/spinal pathologies, previous spinal surgeries, or postpartum pain due to pregnancy (Singh \& Deshmukh, 2022)
