GyroStim and Safety

Uncompromising and committed to safety
GyroStim was inspired by necessity, designed for effectiveness, engineered and built with the highest quality state-of-the-art components, and rigorously tested to exceed industry safety standards.

Millions of spins
One of the strongest indications of GyroStim safety is that after millions of spins in locations around the world, rotating thousands of people from all walks of life, there have been ZERO reports of injury as a result of device malfunction.

Fail-safe design
The GyroStim employs a fail-safe design that returns it to a safe condition should a breakdown or malfunction occur. This design includes numerous hardware and software interlocks that prevent or stop motion of the GyroStim if they are interrupted.

Redundant stop controls
"Stop" buttons are located within easy reach, giving the subject ultimate control to stop the GyroStim and return to home position at any time. A software stop button on the operator screen will produce the same controlled stop routine. In addition, an emergency stop button is located at the operator station. Pressing this button will remove all power immediately from the rotation drive motors, causing the GyroStim to glide to a stop in a safe upright position.

GyroStim has passed rigorous safety testing
GyroStim has undergone safety testing with Intertek Testing Services NA, Inc., a leader in equipment and medical device safety testing. Among the tests GyroStim has passed:

Institutional Review Board Approvals
GyroStim has been approved by multiple Institutional Review Boards (IRBs) as a non-significant risk device for safe use in research using human subjects.

G-force Safety
At its maximum intensity and speed, GyroStim exerts less than 3 G-force: much less than the 5+ G-force of a typical theme park roller coaster ridden by thousands of people each day.

A high-tech spin on a familiar device
Multi-axis rotating chairs capable of producing motions similar to that of the GyroStim were developed and utilized as early as 1960 for use by NASA Mercury astronauts in their pre-flight training. Today they are a standard attraction at space camps and amusement parks all over the world. GyroStim's patented "pitch inside yaw" design sets it apart from all other multi-axis rotating chairs. It is this very specific and unique combination of axis of rotation that produces the unparalleled success of the GyroStim.


The GyroStim measures 8ft x 8ft x 7’8” (9’4” in height with optional patient transfer system). In addition, space is needed for an operator station (small desk or table to hold the interface computer) just outside of the safety perimeter. The recommended minimum room space is 12ft by 14ft.

GyroStim should be placed on a flat and level surface capable of bearing 1,600 lbs, preferably with a hard, non-absorbent finish such as wood, cement or vinyl.

Installation Requirements
Ideally, GyroStim is shipped fully assembled and rolled into place from the point of delivery.  Custom installation may be required if there is not a minimum of 48” clearance along the path from delivery to installation location or if there are multiple stairs. In that case, GyroStim is disassembled prior to shipment, crated and shipped in multiple crates, and reassembled once at the final installation location.
