Inside HITIQ / Our proprietary technology

Movement. Measured. Understood.

01 / Measure

Small enough to wear. Built to capture movement.

Start at the source.

A well-fitted mouthguard couples to the upper teeth, creating a practical location for measuring head movement. Embedded sensors record motion across three axes.

Linear acceleration
How quickly the head changes speed in a straight line. Often expressed in g value.
Rotational motion
How the head turns, and how quickly that turning changes. Adds information beyond a single peak g value.

The 2021 Nexus A9 laboratory study compared mouthguard measurements with reference sensors in a controlled headform test.

02 / Model

Turn recordings into useful context.

Two different questions: does the recording represent an impact, and what can its movement tell us?

ImpactIQ / Event classification

Find the signal.

Triggered recordings pass through quality checks and classification. Fit and movement artefacts matter: a sensor trigger alone does not establish a head impact.

    Detected events

    Recordings that meet capture thresholds.

  2. 02

    Quality & classification

    Processing distinguishes likely impacts from recording noise.

  3. 03

    Impacts for review

    Classified events provide a more useful starting point.

Published science / DAMAGE

More than a peak number.

Rotational movement unfolds over time. The published DAMAGE model uses that motion history to estimate maximum brain strain, the deformation that may occur during an impact.

PROTEQT presents this modelling through its DAMAGE Severity Index (DSI). It is an estimate based on recorded motion, not a direct measurement of injury.

03 / Review

Information for the people who need it.

The measurement becomes useful when it reaches the right person, with the right context.

In the wider context.

Cortex connects athletes, sessions, exposure and available video. Guardian assembles incidents for a welfare team’s review. Each workflow serves a different organisation.

Explore our systems

Sensors measure head movement. Models estimate aspects of the brain’s mechanical response. Clinical assessment determines injury and care. HITIQ informs review; it does not diagnose concussion or clear someone to play.

Evidence & development

Explore the research behind sensor measurement, impact classification and brain-strain modelling.

  1. 01 / Sensor testing

    Testing the mouthguard.

    Stitt and colleagues compared Nexus A9 recordings with reference measurements during controlled headform impacts. The study examines the tested hardware’s measurement performance.

  2. 02 / Classification

    Learning from verified events.

    Goodin and colleagues developed a classifier using Nexus A9 recordings and video-verified events from elite Australian football. The work evaluates identification of head and body impacts in that setting.

  3. 03 / Modelling

    Estimating the brain’s response.

    Gabler and colleagues developed DAMAGE to estimate maximum brain strain from rotational motion histories. This published model research underpins the calculation used in PROTEQT’s DSI.

Each study applies to the hardware, methods and conditions it tested. Measurement and modelling validation are distinct from evidence of clinical diagnosis. ImpactIQ is HITIQ’s proprietary technology; DAMAGE is a published research model.
