Abstract

Background: Facial palsy (FP) is defined as an injury of the seventh cranial nerve pair, partial or total, which can be classified as central or peripheral. Proprioceptive neuromuscular facilitation (PNF) is primarily used in the functional recovery of upper and lower limb conditions, however the technique has also been used for FP.

Objective: To analyze the effect of PNF in the treatment of dysfunctions in FP.

Methods: Ten databases including BVS, CENTRAL Cochrane, CINAHL, PEDro, PubMed, Scielo, ScienceDirect, SCOPUS, Web of Science, and Google Scholar were comprehensively searched for dates prior to April 2021. Randomized controlled trials of PNF in individuals with dysfunctions caused by facial paralysis were eligible. Outcomes measures were recovery rate and clinical recovery, both measured by using the House Brackmann Scale. Recovery time was measured in days and synkinesis assessed with the Synkinesis Assessment Questionnaire.

Results: A total of 184 patients were included. In general, the included studies have low methodological quality. None of the five studies used PNF as the sole intervention. In all of the included studies PNF was used in combination with other interventions. Our findings show very low evidence that PNF is more effective than minimal intervention for treating FP.

Conclusion: We conclude that given the limited number of studies included and the low methodological quality presented, recommendations based on these studies should be interpreted with caution. The effects of PNF on facial paralysis are not clear.

Keywords: Facial paralysis; Kabat; PNF; Proprioceptive neuromuscular facilitation.
