I have a patient in need of an AAC device in order to maintain her PCA services. There is some urgency to getting a device and the state Rehab Commission is willing to pay for it. Looking for recommendations. I would like a Lingraphica but feel that the trial period and purchasing process may further jeopardize her access to personal care. Was thinking of suggesting a Go Talk20 for immediate purchase and then trying for a Lingraphica through her insurance. Any advice would be helpful.
