Clinical decisions around concussion, fatigue, and return-to-play currently rely heavily on symptom self-report — and self-report is exactly what players under pressure to return quickly have an incentive to minimise. EchoDepth Sport gives medical staff a continuously-updated, objective baseline that doesn't depend on a player choosing to disclose.
Every player's facial Action Unit profile is captured pre-season and re-established across the first 3–4 weeks of sessions, creating an individual neurological and emotional reference point. After any head-impact event, post-collision AU patterns are compared directly against that baseline — not a population norm — surfacing deviation in blink rate, gaze tracking, and brow suppression that are established physiological correlates of neurological disruption. This is designed to supplement your existing concussion assessment process with additional objective evidence at the moment of assessment, not replace clinical judgement — the decision to withdraw a player always rests with qualified medical staff.
For the full detection methodology, including the specific Action Unit combinations tracked and how they map to VAD emotional scores, see The Science and Research & Evidence Base.
What Medical Staff Get
Pre-Season Baseline Capture
Every player's AU profile, VAD scores, and micro-expression patterns captured and stored as their neurological baseline under normal conditions. The reference point for all post-impact comparisons.
Post-Impact Evidence Packs
Following a head collision, EchoDepth delivers a full timestamped AU divergence report to medical staff. Richer evidence. Faster. At the critical moment.
Return-to-Play Readiness
Post-concussion AU patterns monitored across training sessions. Support return-to-play clearance with objective evidence that baseline neurological patterns have been restored.
Fatigue & Overtraining Signals
VAD-modelled arousal suppression identifies psychological overtraining markers before they become physical injuries. Inform training load decisions with emotional as well as physical data.
Medical Staff FAQs
How does EchoDepth Sport support medical staff in elite sport?
EchoDepth provides medical staff with pre-season emotional and neurological baselines, concussion protocol support via emotional baseline comparison at each return-to-play stage, and continuous psychological monitoring that identifies players who may be concealing distress related to injury or recovery. The objective signal supplements clinical assessment without replacing it.
Can EchoDepth support concussion return-to-play decisions?
Yes. EchoDepth captures pre-season emotional baselines for each player. Post-concussion, these baselines enable objective comparison at each stage of the graduated return-to-play protocol. Persistent deviation from pre-injury baseline — even when SCAT5 performance has normalised — provides additional clinical evidence to support conservative return-to-play decisions.
Is EchoDepth data admissible in clinical documentation?
EchoDepth produces timestamped, session-level emotional state reports with signal evidence for each assessment. These reports are structured for inclusion in clinical documentation and can form part of the evidenced record for duty of care and concussion protocol compliance purposes.
