HeadX Duo

HeadX Duo combines a head-mounted crosshair laser with an inertial sensor and companion app. During a defined task it records angular head movement and presents the protocol-specific output, such as active movement range or head-repositioning error. A clinician selects the protocol and interprets the result.

HeadX Kross provides crosshair-laser visual feedback without digital data capture. HeadX Duo retains crosshair-laser feedback and adds app-connected inertial sensing, recording angular movement data for repeated-session review. The appropriate device depends on whether the clinician needs visual feedback alone or recorded measurement data.

The inertial sensor records angular head movement during a defined task. The app can present outputs for active cervical movement and angular error during a head-repositioning task. Movement quality, control, symmetry or impairment are clinical interpretations rather than diagnoses generated by the device.

A suitably qualified clinician may select Duo within a defined active cervical movement or head-repositioning protocol. The recorded output is interpreted alongside symptoms, history and other findings. Duo does not diagnose concussion, whiplash-associated disorder, vestibular dysfunction, neck pain or other conditions.

Session data is stored on the device running the HeadX Duo app and can be exported using the functions available in the app. Organisations remain responsible for consent, access control, backup and their own data-governance requirements. Review the current privacy policy and app-store disclosures before deployment.

HeadX Duo is intended for suitably qualified clinicians and researchers who require recorded cervical movement data to support assessment, repeated-session review or a defined research protocol.
