HUMAC NORM – Isokinetic Dynamometer

The HUMAC NORM can be called a few different things, but no matter what you call it, it’s your BEST solution for measuring and improving human performance in the clinic, athletic training room, and research laboratory.

The ultimate in versatility

Sometimes referred to as an Isokinetic Machine, sometimes an Extremity System. In essence, in one machine, you’ll get 22 isolated-joint movement patterns, 4 resistance modes (isokinetic, isotonic, isometric, and passive), and numerous reports to meet the measurement and exercise needs of today’s clinicians and researchers.


Exercise modes include:

  • Continuous Passive Motion
  • Multi-Angle Isometrics
  • Proprioception Training
  • Standard & Eccentric-focused Isokinetic Strengthening
  • Deceleration Training
  • Dynamic Isotonic Training
  • Power Training

Testing modes include:

  • Proprioceptive
  • Isometric
  • Standard Isokinetic
  • Concentric/Eccentric Isokinetic
  • Interrupted Stroke Isokinetic Testing


Unparalleled Mechanical, Dynamometer, and  Software Design

Developed for the Exercise Science Lab and perfected in the Physical Therapy Clinic and Athletic Training Room the HUMAC NORM Isokinetic Extremity System is the machine of choice across all disciplines and around the world.

Mechanical Design

Patented inline design is space efficient, quick to set up, includes 22 standard test & exercise patterns, and is the most stable platform in the market.

Dynamometer Performance

State-of-the-Art Brushless motor offers the widest performance envelope from 1/10 ft/lb and 1/16 /deg/sec to 500 ft/lbs and 500 deg/sec. Ability to rotate the shaft 360+ degrees makes work simulation patterns possible.

Intuitive Software

Intuitive HUMAC Software makes it easy to learn and operate the HUMAC NORM Extremity System. Vivid and unique exercise displays help keep patients motivated. Full-page test, progress and group summary reports make it easy to communicate baselines, progress, and performance relative to local norms.

What’s included

The HUMAC NORM includes attachments to perform 22 isolated patterns covering the shoulder, elbow, wrist, hip, knee, ankle, and back. Optional attachments allow trunk extension/flexion, work simulation, and closed kinetic chain patterns.

The various applications of the HUMAC NORM will fit into your patient’s plan of care, no matter their current phase of rehab.

Longevity in the market

The HUMAC NORM derives from the Cybex NORM created by Lumex in 1995. Computer Sports Medicine Inc’s relationship with Cybex started in 1980 when founder, Rich Potash, designed the first computer software that Cybex paired with their machines to replace the chart recorder. By 2002, CSMi had acquired the rights to the entire Cybex isokinetic testing product line, and for the first time, the NORM machine and HUMAC software were produced by one company. The HUMAC NORM officially released in 2003. With such a stable and robust history you know you’re getting a quality product when you choose the HUMAC NORM extremity machine for testing and rehabilitation.
