The positioning section includes how to set up all of the most commonly used positions. From the ankle up to the shoulder through to the advanced options of the closed chain unit and trunk TMC module. The Full Tests section includes the software, hardware and interpretation of results this section includes commonly used tests and exercises and expands all the time. Other videos includes the advanced software functions including the settings menus, researchers toolkit and group screening modules.


Early stage physical therapy is all about motor control -- move a limb where you want, when you want, at the velocity you want. The HUMAC360 Exercise Guidance System provides a visual goal during exercise that clearly shows where one needs to move (Range-of-Motion), when one should move (Reaction), and a what velocity one should move(Speed).


This closed-loop approach during exercise makes it easy for patients to understand what is being asking of them, to self-correct their performance in real-time, and provides an objective training goal for their next visit. For the clinician implementing closed-loop training means less time will be spent explaining exercise and more time will be spent review performances and getting motivated patients to the next level.

CSMI History

Computer Sports Medicine International ( CSMI ) first became involved with isokinetics in 1980. President and CEO Rich Potash teamed with Cybex (a division of Lumex) to design a PC based computer system for the new Cybex II

In 1982 Cybex produced the Cybex II and started sales in over 20 countries. CSMI released the HUMAC System for the Cybex II

With installations at MIT, MGH, and the U.S. Olympic Training Center. Based on the Apple //e the HUMAC was the first computer/software system to replace the Cybex II Chart Recorder. HUMAC was the first computerized isokinetic data analysis system for the MAC computer system. 1983 CSMI releases the HUMAC Computer System for the IBM PC integrating into the Cybex II main systems

1986 CSMI releases HUMAC upgrades for the Cybex Orthotron II, KT-1, and KT-2 machines and starts exporting software.

The upgrades include custom torque and position sensors along with a modified version of the HUMAC program allowing the Orthotron and KT systems to provide isokinetic testing at a reduced cost. Cybex brand's international presence expanded and developed in the late 1980s. With sales agents in more than 40 countries, the company saw international sales increase 70 percent in 1988, exceeding projections. That year Lumex expanded its product offerings to international clients to include Cybex Back Systems and Cybex Fitness Systems

1988 Cybex Medical,asked CSMI to design and manufacture the Cybex 1000, 1100, and 1200, a low-cost line of isokinetic testing devices based on the Cybex Orthotron Actuator. At the same time they start to buy the HUMAC software for their extremity systems.

CSMI re-designed the actuator incorporating a strain gauge torque sensor and optical encoder position sensor. CSMI establishes manufacturing and testing of the new actuators at the Cybex Owatonna facility. CSMI provides manufacturing and support of the custom interface boards and HUMAC software. The HUMAC software is adapted to English, German, French, Spanish, Italian, and Japanese.

Lumex initiated advisory boards of medical and fitness professionals to help improve existing equipment designs as well as originate new designs. New products included the fourth generation of the Cybex Extremity Testing and Rehabilitation System (Cybex 6000), introduced in 1991.

1991 CSMI designs the Smart Analog Module (SAM) available to all isokinetic extremity system manufacturers.

1992 CSMI releases the HUMAC interface with automatic speed control allowing operators to create automated protocols.

The Cybex 6000 was a technological step forwards for Cybex as the system provided both powered (eccentric) and non-powered (concentric) options and continuous passive motion (CPM).

In 1995 Lumex released the Cybex NORM a single chair / dynamometer configuration, after extensive study of the industry design of T-base and elbow-based machines with tethered computer carts. The engineers and product specialists developed a superior and patented sliding chair / fixed dynamometer configuration with integrated computer system. This remains the industry standard into 2010.


Choosing to focus business operations in the fitness industry, Cybex sold its line of isokinetics testing and physical rehabilitation equipment in 1997. Henley Healthcare purchased the product line and licensed the Cybex brand for the equipment.

1997 CSMI buys the rights to the Cybex II and Cybex II+ systems offering full software and PC updates.

1998 CSMI releases new PC and software systems for the Cybex 300 and Back Systems. This means all previous versions of the Cybex isokinetics systems can now be fully upgraded to modern computers and software. This 'never obsolete' approach sets Cybex apart from the other equipment manufacturers and continues to this day.

1999 CSMI then acquired the rights to the complete Cybex isokinetic testing product line (Cybex II, 300, Back Systems, 6000, and NORM) from 2000 CSMI releases the HUMAC upgrade for the Cybex 6000. The HUMAC replaces the original 6000 DOS-based Computer, Software, DCB, and SCB with the HUMAC Windows software and high-speed, dual-processor, USB-based HUMAC Controller.

2001 CSMI releases the HUMAC upgrade for the Cybex NORM. The HUMAC replaces the original NORM Computer, Windows 3.1 Software, ATIC and NDCB with the HUMAC Windows software and high-speed, dual-processor, USB-based HUMAC Controller.

2002 CSMI purchases the Cybex NORM Systems product line from Znetics. The purchase includes all designs, patents, inventory, and tooling for the continued production and support of the NORM system.

2003 CSMI ships the first new NORM Extremity System powered by the HUMACComputer System.


2007 CSMI releases the new Norm with a  changed and developed software interface. Increased reporting capabilities. Proprioceptive modes. Stand alone modules for researchers and universities. A group screening module to continue to support the sports teams (including the NFL) using the systems world wide. The dynomometer is changed to a brush-less motor allowing the torque level to increase at the higher speed range. A new digital servo amplifier is released increasing data samples from 100 to 5000 samples per second available for the system and for external acquirement through a dedicated board.

2009 CSMI releases integration of touch screen technology and full EMG support.

2012 CSMI announces the new Norm2 at Medica in Dusseldorf Germany. The new system is incorporated into a smaller footprint and has been developed to work with the CSMI functional tool set. Set for release in 2013 this will include the new cable reel technology set.

NORM2-From-Above-with-Wheel Translucent

2013 CSMI releases the Norm2 complete with cable reel technology. This allows for 3 dimensional testing functionally whilst also providing a stable platform for ordinary isolated joint testing. The shaft is able to turn 360 degrees allowing for pulling, pushing and squatting motions as well as all of the functional tools normally only seen in the Occupational Health settings.

Top Tip:

Can't decide which isokinetic speed to use?

Remember for a standard strength test a medium joint speed delivers a good balance of results and comfort.

Simply use the same speed as the range of motion. e.g. with 45 degrees range of motion - then use 45 degrees per second as your speed.
