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 Bell's 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.
