Health Care Professionals

Physical Therapists, Neurologists, Neurotologists, Audiologists, and many other doctors and health care professionals face numerous challenges in addressing the need for evaluating patients in the office or on the sidelines, including objective benchmarking for athletes or newly arrived physical therapy patients.

  • Portability is key. Only NKI’s I-PAS™ offers portable, precise and multi-modal clinical eye tracking technology for field use in vestibular testing.
  • Precision. No other tools have published papers comparable to NKI’s precision and sensitivity.
  • Access. Easy to use software on a variety of platforms provides clinicians, doctors, physical therapists with the access the critical, objective and repeatable, clinical data they need to help their patients.
  • Objectivity. Current testing methods rely on subjective, inconsistently applied methods. I-Portal produces objective data for informed decisions and insurance support.

I-PAS offers professionals a portable solution to objectively baseline and monitor patients and athletes by measuring a wide variety of OVRT (oculomotor, vestibular and reaction time) abnormalities associated with concussions and vestibular dysfunctions.

Sports Organizations

Athletic Directors, coaches, and school administrators are charged with managing safe and successful sports programs, and must juggle issues including:

  • Liability. Increasing incidence of concussions during practice and play has increased liability exposure, and can taint reputations.
  • Recruitment. Concern over concussions has escalated parent/player resistance.
  • Access. PT’s lack objective measurement tools for baselining or testing concussion patients.
  • Objectivity. Current tests rely on subjective, inconsistently applied methods to measure neuro-functional impairment. Not NKI…

I-PAS™ enables Sports Organizations to limit liability, increase trust from parents and players, and provide precise benchmarking and post-injury information on a wide variety of physiological metrics.


Inherent health deficits or external forces, such as a blow that results in a concussion, put athletes at risk. Once injured, their passion to play may be at odds with managing their short- and long-term health. Their challenges include:

  • Self-Assessment. Inability to self-determine impairment if the affected physiology includes cognition or is subtle.
  • Objectivity. Popular concussion assessment tools are imprecise, mostly subjective, and subject to sandbagging.
  • Return to Play. Premature return-to-play puts athletes at greater risk for subsequent injury. And, certain repetitive injuries, for example sustaining multiple concussions, can confound the path to recovery.
  • Benchmarking. Extraordinary performers are less suited to comparisons to the average population (norms).

NKI’s I-Portal® systems provide objective and precise information on a wide variety of physiological metrics important to athletic performance, including OVRT (oculomotor, vestibular and reaction time) function.

Research Solutions


Research has shown that 5 to 6 OVRT tests can collectively separate concussions from controls, and NKI’s technology is the tool upon which this exciting concussion research is based. The sensitivity obtained when testing with I-Portal technology opens exciting opportunities for exploring other injuries and illnesses that are or may be correlated with irregular eye movements, and or to validate drug and rehabilitation therapies to heal patients. Research has shown that abnormal eye movements are correlated with over 200 diseases and medical conditions.

NKI is constantly developing new tests, discovering new variables, and helping researchers profiling new clinical indications, independently, in collaboration with major universities, and government research laboratories. Please contact us with your research interests in the following fields:
