The Effect of Oral Facial Facilitation Therapy on Drooling: A Single Case Study
摘要
To evaluate the effectiveness of Oral Facial Facilitation (OFF) therapy in reducing drooling severity and improving oral motor control, swallowing, and facial tone in adults with neurological impairment. The study aims to address the limited evidence supporting OFF’s role in sialorrhea management within the Indian context. A single-case design was utilized, involving a 56-year-old adult referred for speech assessment and therapy. A comprehensive assessment was conducted, that included cognitive, speech and language, intelligibility rating scales as well as drooling severity/frequency scales. The patient underwent a six-day regimen of Oral Facial Facilitation therapy (icing, brushing, manipulation, and oral-motor sensory exercises), with daily sessions lasting 45–60 min. Baseline evaluation indicated poor oral sensory-motor coordination, weak swallow reflex, and severe drooling. Notable gains were documented in oral motor control, lip strength, tongue retraction, jaw stability, swallowing, and facial tone, indicating effective reduction in sialorrhea. Oral Facial Facilitation therapy, comprising four therapeutic methods, proved effective in controlling excessive saliva production and enhancing neuromuscular learning and sensorimotor control. The outcomes highlight OFF therapy as a practical, evidence-based intervention for adult neurological drooling, expanding its utility for speech-language pathologists and swallowing therapists.
