An efficient and biomechanically precise method of acquiring reliable test data is necessary for advancements in modern spine research and the creation of novel therapeutic and curative approaches and technologies.
The FS20 Biomechanical Spine Test System, created by Applied Test Systems (ATS) in response to this challenge, can test cadaveric spine specimens for flexion/extension, lateral bending, and torsion under physiological loading conditions that mimic the natural range of motion of the human spine.
The FS20 has been developed in close collaboration with leading research universities in the United States to offer an enhanced testing setup that permits unrestricted movement and specimen access. This leads to better test data and more dependable testing across a more extensive range of specimens for accurate results that users and their teams can rely on.

Versatile Motion Capabilities
The FS20 employs two precise torque drives, allowing freedom of movement in all dimensions (X, Y, and Z; translational and rotational) to accurately represent the smooth, continuous motion of the human spine. This allows for a variety of test techniques.

Dynamic Test Data
The FS20 was explicitly created to gather dynamic motion data, which is far more precise and valuable than the static data produced by standard manual tests.

Why Should Users Choose the FS20?
Compared to other spine testers currently available on the market, the FS20 Biomechanical Spine Test System is a well-designed, flexible alternative.
The FS20, which was created in close collaboration with scientists and researchers who frequently use such equipment, aims to improve data acquisition, improve test setup processes, and provide unrestricted spinal motion simulation.
When these capabilities are combined with the FS20's smooth electromechanical actuation, accurate torque application, and computer control via proprietary ATS software, it is the only testing system of choice for modern spine research centers.
For example, the FS20 is currently in use and offers helpful data in studies employing cadaveric spine specimens with the entire ribcage attached. This removes the need for intricate follower load systems and streamlines testing processes. Spine testing has genuinely advanced with the FS20’s 360° access to the full ribcage.
