The CanDo® 14-inch Inflatable Balance Disc Blue is a vestibular, balance and proprioception training aid that can be used while sitting or standing. The round pad easily inflates using a standard air pump. For stimulating sitting balance reflexes, place the disc in a chair for imitating balance ball movements. This dynamic vestibular cushion activates major muscle groups for core, balance training. For stimulating standing balance reflexes and lower extremity strengthening, place the disc on the floor. The level of vestibular challenge can be adjusted by varying the inflation level of the disc. The disc has a smooth flat side and a textured “nubby” side for stimulation and tactile feedback. The disc measures 14 inches in diameter and 2.5 inches high. Other colors available by special request.
