Product Fundamentals

HoweRT® resonance-based devices are designed by InspirStar, Inc. of Chandler, Arizona. As a microcurrent device, the unit generates an electrical current in the millionths of an amp. InspirStar created the first FDA approved programmable microcurrent stimulation machine and was chosen to create the HoweRT® devices due to their high quality and excellent customer service. HoweRT® microcurrent devices are FDA approved and offer Resonance-Based Microcurrent. The units feature an LCD screen to make accessing the dozens of programmed options quick and easy. This ease of use supported the development of very comprehensive units for both the Sport and Home Wellness arenas.

The Programming Makes the Difference!

The programs were developed for the active therapy clinic of Vanessa Howe, MSPT. For more than a decade, Vanessa has been developing programs to better meet the needs of her Physical Therapy practitioners and patients. This has involved an on-going process of clinically-based program refinement across more than 7,000 individual patients.

HoweRT® Micro-Sport® devices are FDA approved micocurrent electrical stimulation units offering Resonance Programmed Microcurrent. These specific devices are approved for pain use. Other uses in this FDA category include wound healing and bone stimulation. Other general uses of microcurrent include aesthetics and general wellness. Our unit is a small, portable machine, which is designed to treat pain in a training room, doctor's office, clinic or hospital, and can also be safely and easily self-administered at home under a doctor's prescription.

HoweRT® Microcurrent devices are high-end precision medical instruments. These products can generate low-current intensity pulses at microampere level and frequency of pulses.

Programming these devices allows for control of the following parameters: current intensity, frequency, time, modulated wave period, wave slope, and polarity. The programs for these specific devices were developed over a decade of active use for pain treatments at a physical therapy clinic in the northern suburbs of Detroit, MI by a national instructor in Resonance Based technologies. Practitioners or users do not need any programming background or skill to use these devices. The programs are easily accessed with a few pushes of a button. Current intensity can be adjusted to maximize comfort.
