X-RTS, an acronym for "cross-reference testing system" is a cost-effective family of tools for use in physical therapy, industrial rehabilitation and athletic training facilities.  The X-RTS Hand Strength Assessment, the most accurate method on the market for assessing validity of effort during a hand strength test, is available in its standard, unlimited use CD version.  However, we are proud to announce our test is now also available for purchase on a "per test" basis on this site.  This product is backed by peer review which was published in the Journal of Hand Therapy in 2002.  The X-RTS Lever Arm, developed to assess validity of effort during a lifting evaluation, is our second testing tool.  The X-RTS Four-Wheeled Cart is a unique device that has both testing and physical training potentials.  A separate page on this site is devoted to each of these products.
