ARKs proBarbell is a fun and engaging way to work on lip closure and lip strength, fundamental skills needed for proper speech and feeding development. Using tongue depressors with quarters taped on either end has been a DIY oral motor exercise for many years. ARK’s proBarbell set offers a fun, high quality upgrade of that oral motor activity – no more small parts or tape to worry about! The blue barbell has the equivalent weight of 1 quarter on each en To use: Place the flat part of the blue barbell in between the lips. Instruct the individual to hold it there (using the lips only, no teeth) to work on lip closure, strength, and endurance. For increased difficulty, use the green barbell which is heavier. Working on lip closure can help improve feeding skills, drinking skills, saliva control, speech sound production, and more.
