FAQ

What does the HeadX Kross measure?

The HeadX Kross projects a patented crosshair laser onto a wall-mounted target, making head and neck position visible in real time across three planes of movement: pitch (flexion/extension), yaw (rotation), and roll (lateral tilt). It is used to identify and quantify joint position error, assess cervical proprioception, and guide sensorimotor retraining.

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

Joint Position Error (JPE) testing measures the accuracy with which a patient can reposition their head to a neutral or target position after an active cervical movement. The HeadX Kross supports JPE testing by projecting a precise crosshair laser onto a bullseye target, allowing the clinician to measure displacement in centimetres and convert it to degrees of angular error. A threshold of 4.5° is commonly used to identify proprioceptive impairment in clinical practice.

Which clinical conditions is the HeadX Kross indicated for?

The HeadX Kross is used in the assessment and rehabilitation of concussion, whiplash-associated disorder, chronic neck pain, cervicogenic headache, vestibular dysfunction, and post-stroke balance impairment. It is also used in sports performance settings to assess and retrain head and neck neuromuscular control.

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

The CROM device and goniometer measure passive or active range of motion in degrees. The HeadX Kross measures proprioceptive accuracy — the ability of the cervical system to return to a known position — which is a distinct and clinically meaningful variable. The crosshair laser also provides real-time visual biofeedback during exercise, which neither a goniometer nor a CROM device offers.

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. The HeadX Kross is designed for both clinic and home use. Its adjustable headband, simple single-button operation, and self-explanatory visual feedback make it suitable for unsupervised home rehabilitation when patients have been shown the protocol in clinic. The HeadX exercise library provides structured home programmes aligned to the device.

What laser class is the HeadX Kross?

The HeadX Kross uses a Class 1 laser, which is safe for use in clinical and home environments without the need for protective eyewear or specialist laser safety precautions.
