Who is MD Systems?

MD Systems, Inc. is a product development company with a focus on improving health through technology innovations.  It has a history dating back to the mid 1960's and research related to physiological factors associated with pilots flying the new "fly-by-wire" F-16 aircraft. Results of that research revealed insights into the utility of controlled isometric exercise regimens to improve cardiovascular health. The company's first commercial product, CardioGrip, was released in 1997 following FDA review for improving cardiovascular fitness.


On-going research into physiological mechanisms associated with use of controlled isometric exercise regimens yielded a clear understanding of how these modalities could be utilized to significantly improve muscular strength, stamina,new interventions and provide markers predictive of future changes in health.  


The company's current DynX product is a portable battery powered hand-grip exercise device used for various test and exercise purposes within sports training, research, medical practices, functional capability evaluations, and by anyone seeking a scientific approach to exercise for upper body strength, general fitness and endurance.

Organized under the laws of Ohio, MD systems is a privately held corporation which retains ownership of numerous U.S. and international patents for its designs of controlled, interrupted, isometric, isokinetic, isotonic and isodynamic exercises including methids, hardware, firmware and utility.

The strength of a person’s hand-grip could be an indicator of their cardiovascular risk, suggest findings from a major study published in The Lancet.

The research, which included almost 140,000 people from 17 countries found that having a weak grip strength was associated with an increased risk of heart attack, stroke and shorter survival.
