Innovating Since 1982

In 1982 CSMi was the first company to upgrade a CYBEX II Isokientic Extremity System with an Apple //e computer running our HUMan Assessment Computer Software (HUMAC). Since then over 2,000 CYBEX and Biodex Owners have upgraded to HUMAC for a fraction of the price of a new machine. Once updated, you will always have the option to keep your software current because the latest versions of HUMAC are always backwards compatible.

Find out just how useful your CYBEX or Biodex can be with HUMAC.
