Abstract

Background: Neuromodulation is the alteration of neuronal and synaptic properties by neuronsthemselves or by substances released by neurons.Objective: To evaluate the effectiveness and safety of peripheral nerve stimulation and pulseradiofrequency in the management of Bell's palsy.Patients and methods: A clinical therapeutic trial study was conducted in Al Arabi Private Hospital, Iraqduring the period from the 1st of January to the 1st of December 2023. A convenient sample of 50patients who presented with unilateral Bell's palsy were enrolled. Inclusion criteria included patientsaged≥18 years and those who did not respond to medical conservative therapy. The interventionincluded sensory nerve stimuli, motor nerve stimuli, and pulse radiofrequency for two sessions at threemonth intervals.Results: There was a notable enhancement in facial symmetry during periods of rest, voluntarymovements, synkinesis, and sensory impairment following the initial session, as well as after the secondsession in comparison to the first session. The first session resulted in a notable reduction in thepercentage of patients exhibiting normal facial expressions and those experiencing mild paralysis, ascompared to their pre-intervention condition. Following the second session, there was a notable rise inthe percentage of patients exhibiting normal facial expressions in comparison to the initial session.Conclusion: Sensory stimulation, motor stimulation, and pulse radiofrequency are viable and securemethods for managing patients with Bell's palsy
