    Instant Feedback

    Immediate crosshair-laser feedback lets the person and clinician observe target error and unwanted tilt during the selected task.

    Three-Plane Visual Feedback

    The crosshair makes head position and orientation visible across pitch, yaw and roll. Kross provides visual feedback rather than recording digital movement data.

    Clinician Designed

    Clinician-led design supports practical fitting and consistent exercise delivery in clinic or, after appropriate instruction, at home.

FAQ

What does the HeadX Kross measure?

HeadX Kross projects a crosshair laser onto a wall-mounted target, making head position and orientation visible across pitch, yaw and roll. It does not record digital movement data. A clinician can use a consistent target-and-distance protocol to observe movement quality and manually calculate head-repositioning error.

What is Joint Position Error testing and how does the HeadX Kross support it?

Joint Position Error testing assesses how closely a person returns the head to a reference position after active movement. Kross projects a crosshair onto a target so displacement can be read in centimetres and converted to angular error using the test distance. A mean error of approximately 4.5° has historically been used as a reference in some protocols, but it is not a universal diagnostic, recovery or discharge threshold.

In which clinical settings might HeadX Kross be used?

A suitably qualified clinician may select Kross when cervical movement, head-repositioning, gaze-control, balance or head-control tasks are relevant to an assessment or rehabilitation plan. Kross does not diagnose concussion, vestibular disorders, neck pain or neurological conditions.

How does the HeadX Kross differ from a CROM device or goniometer?

CROM devices and goniometers are used to quantify cervical range of motion. Kross provides crosshair-laser feedback for head-repositioning and exercise tasks; any displacement or angular error is read and recorded manually. HeadX Duo adds app-connected digital movement recording.

What planes of movement does the HeadX Kross assess?

The HeadX Kross provides feedback across all three rotational planes: pitch (nodding — flexion and extension), yaw (turning — left and right rotation), and roll (tilting — lateral flexion). Research indicates it is most appropriate for assessment in the sagittal and transverse planes; the coronal plane requires additional consideration in clinical interpretation.

Can the HeadX Kross be used for home-based rehabilitation?

Yes, after appropriate fitting and instruction. A clinician should confirm that home use is suitable and select the exercise, dose and progression. The HeadX exercise library provides a graduated framework rather than an individual treatment prescription.

What laser class is the HeadX Kross?

HeadX Kross uses a Class 1 laser. Use it according to the supplied instructions, do not deliberately stare into the beam, and check the product guidance if you have any safety questions.
