GyroStim Science and Technology

Relative Intensity Protocols

In a 2015 study, Klatt et al. propose that a structured, progressive exercise framework has the potential to maximize postural control and decrease symptoms of dizziness/vertigo in patients with balance and vestibular dysfunction. They also emphasize the importance of addressing boredom and plateaus. GyroStim provides a library of protocols of relative intensity that serves as a framework for data-driven progression of individualized treatment programs.


Relative intensity protocols are a series of motion profiles stored in a the library within GyroStim software. There are 30 levels of protocol intensity. The protocols provide precise control of all motion parameters and exploit the full range and fidelity of GyroStim’s treatment capabilities. The library of protocols makes it easy and quick for the clinician to select, load, and run a profile with a desired level of intensity.

Each run protocol is identified with nomenclature denoting its level of relative intensity, which many clinicians refer to as the “dosage” of intensity. The relativity of one level to the next is based on the intensity of stimulation, which is a function of quantifiable motion parameters programmed into each profile, including the chair’s rate of motion, degree of off-vertical axis tilt, and the exclusion or inclusion of full inversions and continuous rotations:



  • Level 2 protocols generate a relatively low level of stimulating motions at a rate of 2 RPM. The motions are of a repeating pattern (predictable motions), and the patient does not invert.

  • Level 19 protocols generate a relatively high level of stimulating motions at a rate of 19 RPM. The motions are randomized (unpredictable motions), and the patient will rotate continuously through 360 degrees, and inversions will occur.

Relative intensity protocols allow clinicians to administer clinical applications of precise dosages of controlled intensities of motion induced stimulation. The precise dosages provide clinicians with a means for administering a series of incrementally advancing dosages of stimulation at a progression rate specific to the individual needs of the patient, resulting in treatment sessions that are structured, efficient, and effective.
