The TongueFlex Pro device is a specialized tool targeting tongue muscle strength to address swallowing difficulties. It employs two modes to fortify different tongue muscle groups. Mode one concentrates on intrinsic muscles like the superior and inferior longitudinal muscles, also enhancing tongue bone movements. It emphasizes training for transverse and vertical muscles, aiming to ameliorate swallowing function. Mode two involves exhaling and inhaling exercises, especially beneficial for those with severe swallowing strength decline. This mode focuses on tongue elevation movements.
