HeadX

A small multicentre trial found greater improvements in pain and disability after six weeks of device-guided craniocervical exercise than after standard neck exercise or usual care. The result is promising,...

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.

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.

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.

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.
