The Acuscope and Myopulse were developed over 30 years ago and were the first microcurrent devices approved by the FDA. The current output of these modalities is determined by the tissue it is treating. In other words the instruments' microprocessors continuously monitor tissue impedance and in turn provide a gentle microcurrent that is usually not felt by the patient. This proprietary microcurrent waveform is meant to stimulate tissue repair rather than muscle contraction and therefore accelerates our body's own healing mechanisms. The battery operated Acuscope and Myopulse are subtle balancing devices and are extremely safe and easy to use. They are one of a few modalities available that can be used on the head, neck and across the brain. Therefore they are extremely effective for whiplash, headaches and sleep disorders. Because the gentle current output of the Acuscope and Myopulse is meant to balance the body, there are no known contraindications.
