HeadX

In a study of 156 elite and pre-elite female athletes, those with a recent concussion history more often had selected cervical examination findings. Flexion joint-position error was also higher, even...

Illustrative cyanotype scene of an adult using a generic head-mounted laser with a small HeadX Bars I wallchart, red crosshair and three-dimensional movement arcs. Campaign artwork, not the study setup.

When the laser stays on target: what a three-pl...

HeadX

A 2026 study compared a head-mounted laser with three-dimensional inertial measurement. The laser represented small flexion, extension and rotation reasonably well, but lateral flexion told a more complicated story.

Layered paper-cut clinical scene of a seated person wearing a HeadX-style crosshair laser and facing the HeadX Bars I straight-line wallchart while a clinician observes.

HeadX

Thirty people with chronic neck pain repeated four laser-guided head-movement paths 24 hours apart. The straight paths produced more consistent results than the curved path, although the study only tested...

HeadX

A 2026 clinical review argues for profile-guided assessment of vestibular symptoms after sports concussion: screen the likely source, examine it properly and match rehabilitation to the findings.

Linocut-style cervical profile with a global movement arc divided across separate vertebral segments.

Global and Segment-Level Cervical Motion Answer...

HeadX

Global cervical ROM provides an accessible view of overall movement, while specialist imaging investigates how that movement is distributed between vertebral levels. A small 2026 study helps clarify the difference.
