Pneumatics Provide Tight Position Control

Published: August 5, 2008

Spinal cord injury (SCI) has potentially devastating consequences. As of June 2006, over 253,000 people in the U.S. had structural or Functional issues related to spinal cord injuries. Evaluation of spinal implant devices requires testing systems that can replicate the complex motions and loads human joints commonly undergo. Continually improving equipment that can perform tests of strength, range-of-motion, and endurance contributes to breakthroughs in the treatment of SCI patients.

The Datum Spinal Joint Endurance Testing Machine – recently designed and built by Datum Industrial Design, Inc., North Bergen, New Jersey – evaluates how spinal joints will function in human bodies. The machine can be programmed for specific operating parameters so that it can test a variety of spinal joints in a range of scenarios. The machine demanded tight force or position control, but its loads did not justify hydraulics.
