What is this study studying for Bell's palsy?

This study is comparing different laser treatments to see how they affect nerve healing in people with Bell's palsy. Researchers want to learn which laser type may improve facial nerve recovery and support better rehabilitation. The study is sponsored by Kafrelsheikh University and focuses on improving care for this condition.

Who may be eligible for this Bell's palsy clinical trial?

Adults aged 18 and above with a diagnosis of unilateral Bell's palsy may be eligible. Both men and women can join if they have facial paralysis on one side and meet certain nerve function levels. People with central nervous system problems, facial sensory loss, or severe high blood pressure are not eligible. Please review eligibility criteria for more details.

Is there any cost to participate in this Bell's palsy clinical trial?

Study-related care, including the study devices and all trial visits, is provided at no cost. However, personal travel expenses to attend the visits may vary and are not guaranteed to be covered.

What this Trial Is About

This research aims to compare how different laser wavelengths 808 nm, 980 nm, and 1064 nm affect nerve healing in patients with Bells palsy, a condition causing facial paralysis and movement problems. By studying these laser treatments, researchers hope to improve clinical care, rehabilitation methods, and quality of life for people with this nerve disorder. Participants are randomly assigned to one of four groups a sham laser device group, a Low-Level Laser Therapy group, a gallium arsenide diode laser group, or a high-intensity laser treatment group. Each group receives 18 treatment sessions over six weeks, with three sessions each week. All participants also receive facial muscle massage and exercises to support nerve recovery. During the study, researchers will assess the facial nerve function using compound motor action potential tests at the start and after six weeks of treatment. Other assessments include facial disability scoring and monitoring of therapy sessions. The total study period includes the six-week treatment phase, with safety and progress tracked throughout.
