Make head movement visible.

In clinic and at home.

Two images showing a person with a headlamp labeled 'Duo' and a woman sitting in a room labeled 'Kross'.

Two tools, two levels of feedback

Both make head and neck movement visible. The difference is whether you need immediate laser feedback alone or angular movement recorded in the companion app.

Immediate visual feedback

HeadX Kross

Makes crosshair position and unwanted tilt visible relative to a target during clinician-selected tasks. No app or digital recording is required.

Understand Kross

Visual feedback plus recorded movement

HeadX Duo

Adds app-connected angular recording for defined active-movement and head-repositioning tasks, with session outputs available for review.

We have been integrating the HeadX Kross into our rehabilitation and have found it a highly valuable tool. Giving immediate feedback, it has been useful across a wide spectrum of clients - from subtle head positional sense and vestibular issues, to clients presenting with significant motor, sensory and postural control challenges following larger brain injuries

The HeadX Kross is a standardised part of our assessment in the Concussion Clinic at ISEH. Over the past few years, the work conducted here at UCL, alongside research from our peers globally, has highlighted the importance of assessing cervical proprioception following rapid head accelerations.

Feedback of head position in space using head torches or lasers has become an integral part of our vestibular and cervical rehabilitation. The new HeadX Kross gives feedback in the roll (lateral tilt) which adds a new dimension to our ability to train head and neck control.

I like the HeadX Kross as it provides so much more feedback on quality of movement than a single point laser. A single point laser will show if the patient is able to return the head to the starting position but won’t give feedback about head tilt like the HeadX Kross."

Make movement visible. Make progress measurable

HeadX designs two head-mounted devices for clinician-selected head and neck assessment and exercise tasks.

HeadX Kross projects a crosshair laser so head position can be observed relative to a target. It does not record movement data.

HeadX Duo combines the same visual feedback with an inertial sensor and companion app that record angular movement during defined tasks for session review.

Both devices display or record movement; a suitably qualified clinician selects the protocol and interprets the result within the wider assessment.

What is cervical proprioception training?

Cervical proprioception is the ability to sense the position and movement of the head and neck in space, informed by cervical, vestibular and visual inputs.

Head-repositioning performance may be explored through a defined task in which a person moves away from and attempts to return to a reference position.

Kross makes crosshair position visible relative to a target so a clinician can record displacement manually. Duo can record angular repositioning error in the companion app. Neither result is a diagnosis or a stand-alone recovery or discharge threshold.

What is cervical range of motion measurement?

Cervical range of motion describes neck movement across flexion, extension, lateral flexion and rotation.

Published adult reference values vary with age, method, device and population. Range-of-motion testing can document baseline performance and change over time, but a single value is not diagnostic and should not be used alone as a recovery or discharge criterion.

HeadX Duo records cervical movement digitally across the available assessment planes using its integrated inertial sensor, supporting repeated-session review in the companion app.

What is cervical motor control training?

Cervical motor control describes the coordinated activity used to regulate head and neck movement during a task.

A clinician may select precision positioning, active movement, gaze or dual-task exercises after assessing the individual. Kross shows crosshair position relative to a target; Duo can also record angular movement during a defined task.

The devices do not identify an impairment or determine treatment response. Task selection, dose, progression and interpretation remain clinician-led.
