Vitascans' Touchstone Electronic Muscle Tester

The Touchstone is priced for the health aware consumer as well as the healthcare professional.

Today, Santa Cruz, California-based health tool developer Vitascans announced the availability of the Touchstone, the world’s first dual-purpose Electronic Muscle Testing (EMT) device ( see video ) for the mind and body, designed for the healthcare professional and well priced for the the health conscious consumer. This portable microprocessor-controlled, two-ounce and two-and-a-half-inch disc, is based on the principles of Applied Kinesiology (AK) and was developed in response to the growing number of people who want to have a better understanding of their bodies and have more control over their health and wellness.

The Touchstone tests not only an individual body’s physical response to foods, products and supplements, but also gauges one’s emotional response to a personal statement or thought. The Touchstone stores and compares two thumb pressure readings to indicate whether a person’s physical or emotional response is beneficial, detrimental or neutral, determined through the flashing of green, red or amber lights.


Once the one/off button has been pressed, a single orange light will flash. Then the Touchstone is set to one’s personal level of strength (described in the simple instruction booklet ) and a single orange light will flash. When the center button is firmly pressed, until the flashing light remains solid, then the user picks up either a food or vitamin and then presses the center button again until either ‘red’ lights appear, suggesting that the substance is potentially negative, or ‘green’ lights appear suggesting that the product is beneficial, or ‘orange’ lights appear suggesting that the effect is neutral to the body.


The Touchstone development team included, Franklyn Eventoff, the inventor of the force-sensing resistor and Peter Mackeonis, an international consumer design and marketing professional for over 25 years for companies such as: GLOtoSLEEP, YAHOO!, Triangle Publishing, LG, IBM, Atari and Commodore Amiga.


Applied Kinesiology (AK) is an alternative medicine practice used for diagnosis and determination of therapy. According to practitioners using Applied Kinesiology techniques, it provides feedback on the functional status of the body. In 1979, George Goodheart, the Founder of Applied Kinesiology, accompanied the US Olympic team to Lake Placid, NY in the XIII Olympic Winter Games, as the first official US Olympic team chiropractor.


While primarily used by chiropractors, muscle testing is now also used by a number of other alternative health practitioners. Many medical doctors, nurse practitioners, dentists, naturopaths, physical therapists, massage therapists, nutritionists and nutritional supplement distributors use this technique. In 2003, it was the tenth most frequently used chiropractic technique in the U.S, with 38% of chiropractors employing this method and 13% of patients being treated with it.
