A TheraTapper™ provides alternating bilateral stimulation (ABS) for DNMS and EMDR therapy. It consists of a control box connected to two small (hand-holdable) pulsers by six-foot wires. The pulsers vibrate in an alternating fashion to provide a gentle tactile stimulation which many find soothing and relaxing. The stimulation is comparable to the vibration of a pager or cell phone.
