Abstract
Purpose
Repetitive Peripheral Magnetic Stimulation [rPMS] is a non-invasive tool that has a potential therapeutic role in many musculoskeletal disorders. We aimed to demonstrate the therapeutic efficacy of high frequency [rPMS] in acute Idiopathic Facial Nerve Palsy [IFP]. And to study the role of neuromuscular ultrasonography in acute idiopathic facial palsy.
Methods
Forty patients, aged above 18 years, diagnosed with unilateral acute [within 7 days of onset] idiopathic facial palsy were enrolled and randomly divided into intervention group [20 patients] and control group. Both groups underwent clinical examination, assessment of facial nerve disability by House-Brackmann grading [HBG] score and Facial Disability Index [FDI] score, ultrasonography of facial nerve of both normal and affected sides at baseline and after 6 weeks, medical treatment and routine rehabilitation therapy. The intervention group were subjected to 10 sessions of high frequency r PMS [5/week for 2 successive weeks] on the affected side.
Results
Both [HBG] and [FDI] showed more significant improvement in the intervention group in comparison to the control group after 6 weeks follow up. Ultrasonographic measures of facial nerve in the affected side were significantly larger than non-affected side at baseline. However, those measures significantly decreased after 6 weeks follow up. Surprisingly, the intervention group showed more significant decrease in facial nerve dimeter at proximal portion [without sheath] in comparison to control group.
Conclusion
high frequency r PMS have an adjuvant role in treatment of acute idiopathic facial palsy. Also, ultrasonography has beneficial role in evaluation and prognosis of [IFP].
