The 7-module battery

A clinician-grade concussion battery,
scored by the phone in their pocket.

Seven modules, fifteen minutes per athlete, zero computer lab. Every score is objective — voice recognition handles the cognitive modules and motion sensors handle the balance modules.

Module by module

Every test, one tap away.

HQ Baseline delivers a full seven-module concussion battery and makes every item self-administrable. Here is what the athlete actually does on their phone.

  1. 01

    Orientation

    ~60 seconds

    The athlete answers five short questions about time, date, and place. HQ uses a date-aware validator that accepts natural language, not just rigid strings.

    Month, date, day, year, approximate time.

  2. 02

    Immediate memory

    ~3 minutes

    The athlete hears a list of ten common words, three trials in a row, and repeats them back after each trial. Voice recognition scores recall in real time with a fallback tap-to-confirm.

    10 words · 3 trials · standardized word lists.

  3. 03

    Concentration

    ~2 minutes

    Digits backward and months-of-the-year backward. Voice recognition parses the answers; response time and errors are recorded automatically.

    Digit span backward + months backward.

  4. 04

    mBESS (modified Balance Error Scoring System)

    ~3 minutes

    Double-leg, single-leg, and tandem stance for 20 seconds each on firm ground. The phone's accelerometer and gyroscope detect sway errors objectively — no proctor counting.

    3 stances × 20 seconds · motion-scored.

  5. 05

    Tandem gait

    ~90 seconds

    The athlete walks heel-to-toe along a three-meter line, turns, and walks back. Three timed trials. The phone's motion sensors time each trial and flag missteps.

    3 × 3m heel-to-toe walk.

  6. 06

    Delayed recall

    ~60 seconds

    After a five-minute delay (filled by the other tests), the athlete recalls the original ten-word list one more time. Voice-scored, no writing.

    Same 10 words · one final trial.

  7. 07

    Simple reaction

    ~90 seconds

    Five trials with randomized 2–5 second delays. The athlete taps as soon as a target appears. We record millisecond reaction times and variability.

    5 trials · randomized delay.

After the test

Scoring, storage, and subtype comparison.

Results land in the athletic trainer’s dashboard within seconds. Every module is scored automatically — word-recall accuracy, digit span correctness, months-backward time, sway error counts, tandem gait time and variability, delayed recall, and simple reaction time. There is no manual scoring step.

When an injury is suspected later, the athlete retakes the same battery on the sideline or in the clinic. HQ automatically compares post-injury values to the personal baseline, not a population average. Symptoms (PCSS) are mapped across four subtypes — cognitive, vestibular-ocular, anxiety/mood, and cervical/headache — so clinicians can see which dimension changed most.

That subtype-aware comparison is what separates HQ from legacy paper SCAT5 and single-dimension tools. You don’t just see a number that’s worse; you see whereit’s worse.

How it works — frequently asked

Can athletes really self-administer the whole thing?
Yes. Every module is voice-prompted. The athlete follows on-screen instructions, speaks answers aloud, and places the phone against their body or on the floor for balance tests. No clinician is needed during the test itself — though an athletic trainer reviews results afterward.
What if an athlete has a learning difference or can't hear a prompt?
Every voice prompt has a text fallback on-screen, each audio clip can be replayed, and reading speed is adjustable. We also support Spanish voice prompts, with more languages on the way.
Does the app use the camera?
No. Balance is scored by accelerometer and gyroscope, not video. That keeps the test private and means the phone can sit in a pocket or against the chest during stance tests.
How is tandem gait timed?
The athlete holds the phone against their sternum. Motion onset detects step start, return-to-origin detects completion. Three trials are averaged and variability is reported.
