Define the decision before opening the report
Begin with the practical question. Are you checking whether a measurement is repeatable, exploring a training response or supporting a broader clinical review? Each purpose requires different evidence. A model built to distinguish movement styles may be useful for descriptive feedback while offering no validated basis for restricting participation. Calling every output “prevention” obscures these differences.
A worthwhile decision process identifies who is responsible, what information is relevant and what could change after the result. If nobody can explain what a flag would trigger, the system may add anxiety without adding value. Avoid collecting sensitive information merely because it might become useful later. Purpose should guide both measurement and access.
Place the finding in its clinical and sporting context
Current symptoms, previous injury, recent exposure, recovery, training goals and the demands of the sport can all affect interpretation. A change after an unusually demanding week may have a different meaning from a stable pattern observed over months. Even then, the measurement cannot establish the reason for the change by itself. Ask the athlete what the session felt like and whether the recorded task resembled their usual movement.
Clinical assessment has a different role from statistical pattern recognition. Qualified professionals integrate a history, examination and other information when appropriate. A low model score should not be used to dismiss symptoms, and a high score is not a diagnosis. Return-to-sport decisions require a broader assessment than a successful movement screen or a favourable dashboard colour.
A difference is not automatically a deficit
Side-to-side differences are common in sport, especially when tasks and roles are asymmetric. A measured difference can reflect skill, anatomy, adaptation, fatigue, discomfort or noise. Its meaning depends on the feature, protocol and person. Applying a universal cutoff without evidence for that use can turn ordinary variation into an apparently medical problem.
Likewise, a group average is not a blueprint for every athlete. An individual may use a movement strategy that differs from a reference group while performing effectively and without symptoms. Before proposing a change, ask whether the feature is modifiable, whether modifying it is supported by evidence and whether the proposed action could create other difficulties. A tidier-looking movement is not necessarily a safer one.
Choose proportionate actions and explain the uncertainty
A flagged observation might justify checking the recording, repeating the task under comparable conditions or arranging a conversation with an appropriate practitioner. More consequential actions, such as restricting participation, need stronger justification and clear accountability. The threshold for action should reflect its likely benefit, burden and potential harm rather than the visual intensity of the warning.
Use language that distinguishes observation from inference. “The system estimated a different landing pattern today” is more faithful than “Your knee is at risk”. Explain what the tool was studied to do, what it has not established and why a particular next step is being considered. Invite questions and avoid presenting uncertainty as a failure: uncertainty is part of the evidence.
A short interpretation checklist
- Was the recording technically acceptable?
- Is the finding larger than expected measurement variation?
- Does the model apply to this person, task and setting?
- What do symptoms, history and exposure add?
- What proportionate action is supported, and who will review it?
Separate performance development from health claims
Coaches may reasonably use feedback to develop a skill without claiming that it prevents injury. Keep those objectives explicit. If a programme aims to improve technique, evaluate technique and relevant performance outcomes. If it claims to reduce injury, it needs injury outcomes measured with appropriate follow-up and exposure information. Success on the first objective does not demonstrate success on the second.
Public programmes such as FIFA 11+ provide examples of structured exercise approaches evaluated in defined sporting contexts. Their existence does not validate a separate AI screening product or prove that a personalised model adds benefit. Consider the evidence for the intervention itself, then ask whether selecting or adapting it through the model improves decisions beyond existing practice.
Protect trust as well as data
Athletes should understand who can see their results and how those results may influence selection, employment or care. Health-related inferences deserve particular care, even when they originate from an ordinary training video. UK GDPR and the Data Protection Act 2018 are relevant in the United Kingdom; organisations should obtain appropriate legal and governance advice rather than assuming consent resolves every issue.
Guidance from the International Olympic Committee, the British Association of Sport and Exercise Sciences and the Chartered Society of Physiotherapy can help frame professional responsibilities. No external body named here endorses this website. The central principle is practical: use the least intrusive information necessary, keep decisions explainable and allow the athlete’s voice to remain part of the process.
Limitation: a cautious process cannot make an unvalidated model valid
Good communication and professional oversight reduce some risks, but they do not substitute for evidence that a model measures and predicts what its provider claims.
