This well known and effective tool is used to 'wake up' the mouth by providiing gentle vibrationary oral stimulation and sensory input. It can be used to improve a variety of speech, feeding and sensory skills by providing targeted tactile cues within the mouth.Supervision from either an OT or a Speech Pathologist is highly recommended to establish a specific programme. Children can hold the Z Vibe themselves, or someone else can hold it for them. There is lots of information in the resource book - Tools and Techniques for the Z Vibe (see below). There are a variety of different attachment tips to choose from, all designed to achieve specific goals. The tool includes a medical grade, latex free plastic handle in light blue or royal blue, a preefer tip, and a battery.Please note: The unit comes with a special Vibe Battery not available in stores. We recommend buying a spare at the time of purchase. To turn the unit on, simply twist the Switch Tip just until it starts to vibrate (please do not over-tighten!). Caution: the Z-Vibe is NOT a toy. It is a therapeutic tool intended to be used by a professional therapist (or by parents trained by their therapist). It contains small parts (including a battery) that may pose a choking hazard: direct adult supervision is required at all times.
