Effect of Infrared and Myofascial Release in Bell’s Palsy: A Case Report

Abstract

Background: Bell’s palsy is a peripheral facial nerve paralysis characterized by unilateral facial weakness, impaired facial symmetry, and reduced facial muscle function. Infrared therapy and myofascial release are physiotherapy modalities that may support facial rehabilitation through tissue relaxation and neuromuscular facilitation.
Objective: This study aimed to analyze the effect of combined infrared therapy and myofascial release on facial function, pain intensity, and facial muscle strength in a patient with Bell’s palsy.
Methods: This case report involved a 65-year-old woman diagnosed with right-sided Bell’s palsy at RS Soerojo Magelang. The patient underwent six physiotherapy sessions over three weeks. Infrared therapy using non-luminous infrared radiation (780–1400 nm) was administered for 15 minutes, followed by 10–15 minutes of myofascial release using gentle sustained pressure and fascial stretching techniques. A home program consisting of mirror exercises was also prescribed. Outcomes were evaluated using the Numeric Rating Scale (NRS), Ugo Fisch scale, House–Brackmann grading system, and Manual Muscle Testing (MMT).
Results: Pain intensity decreased from 2–3/10 to 0/10 on the NRS. The Ugo Fisch score improved from 63 to 88, indicating improvement from fair to good prognosis. Facial muscle strength and facial symmetry also improved, particularly in the frontal and oral regions. No adverse effects were observed during the intervention period.
Conclusion: The combination of infrared therapy and myofascial release demonstrated potential clinical benefits in reducing pain, improving facial muscle strength, and enhancing facial symmetry in a patient with Bell’s palsy.
