Current approach
✗Subjective symptom reporting
✗Brief cognitive tests — point-in-time only
✗No pre-injury objective baseline
✗Player may mask symptoms under pressure
✗Return-to-play based on symptom resolution
EchoDepth Sport
✓Objective personal baseline per player
✓Regular voluntary check-ins keep the baseline current
✓Post-impact delta against baseline
✓Objective signal alongside player self-report
✓Return-to-play with objective baseline restoration evidence
The 5-Step
Protocol
01
Pre-Season Baseline Capture
Each player's AU profile, VAD scores, and micro-expression patterns are captured and stored as their individual neurological baseline under normal conditions. This is the reference point for all future comparisons.
02
Regular Check-Ins
Players complete short voluntary check-ins through the season, keeping each baseline current. No interruption to warm-up, play, or half-time — so when an impact event occurs, there is recent data to compare against.
03
Post-Impact Check-In
Following a head collision, a post-impact check-in is compared against the player's baseline. EchoDepth flags deviations in blink rate, gaze tracking (AU 41/42), brow suppression (AU 4), and asymmetric facial activation — all established physiological markers of neurological disruption.
04
Medical Staff Alert & Evidence Pack
If deviation exceeds threshold, medical staff receive an immediate alert with a full timestamped AU divergence report. This supplements — not replaces — clinical concussion assessment. Richer evidence. Faster.
05
Return-to-Play Readiness Tracking
Post-concussion, AU patterns are monitored across training sessions. Return-to-play clearance can be supported with objective evidence that baseline patterns have been restored — not just symptom self-report.
Key Post-Impact Signals
AU 41/42
Gaze Tracking
Lid droop and slit — deviations indicate oculomotor disruption consistent with concussive impact
AU 4
Brow Suppression
Brow lowerer — suppression patterns linked to neurological stress response
Blink Rate
Blink Frequency
Significant deviation from baseline blink rate is an established physiological concussion marker
Asymmetry
Facial Symmetry Delta
Asymmetric AU activation post-impact indicates possible neurological disruption to motor pathways
Concussion Protocol FAQs
Does EchoDepth Sport replace clinical concussion assessment?
No. EchoDepth Sport supplements clinical concussion assessment — it provides medical staff with additional objective evidence at the critical moment. The decision to withdraw a player always rests with qualified medical professionals.
How long does pre-season baseline capture take?
Meaningful baselines are typically established across 3–4 weeks of pre-season sessions. The more sessions captured, the more robust the baseline profile.
Can EchoDepth Sport detect post-concussion symptoms during training?
Yes. AU patterns are monitored across post-concussion training sessions, enabling medical staff to track neurological recovery with objective data rather than symptom self-report alone.
Is EchoDepth Sport validated for use in concussion assessment?
EchoDepth Sport's AU detection is built on the peer-reviewed FACS framework. The specific AU markers tracked are established in academic literature as physiological correlates of neurological disruption. Deployment is always as a supplement to — not replacement of — qualified medical assessment.
