Assess how you move and identify risky knee biomechanics. Get insight, training tips and clinic location information to help reduce your chance of ACL injury.
Move Smarter. Improve Your Form.
ACL injuries can be devastating — especially for athletes who jump, pivot, and land as a part of their sport. But what if you could get an early look at how you move and where the injury risk might be hiding?
Hurtblocker gives you a simple, at-home movement check-up. No fancy gear. No complicated setup. Just clear, fast feedback on your landing mechanics and performance.
Whether you’re an athlete, a coach, or a parent, Hurtblocker helps you identify movement patterns that may be linked to a higher chance of ACL injury — particularly poor landing form, asymmetry, or instability.
What the App Does:
• Guides you through specific athletic stress tests
• Uses your phone or tablet camera to capture your movement
• Analyzes key joint positions during landing
• Flags movement patterns associated with elevated ACL injury risk
• Provides a simple summary of your results
• Offers curated links to expert resources, training programs, and clinics
Who It’s For:
• Athletes in high-impact sports (e.g., soccer, football, basketball, volleyball, etc…)
• Coaches and trainers who want a quick screening tool for their teams.
• Parents of young athletes looking to keep them safer.
• Rehabilitation professionals needing a first-line assessment.
• Anyone curious about how they move and where to improve.
Why It Matters:
• Most ACL injuries happen during non-contact events — landing awkwardly, cutting without control, or decelerating improperly. These moments often reveal weaknesses in neuromuscular control that can be trained — but only if you know what to look for.
• This app isn’t a diagnosis or a replacement for medical advice — it’s a movement awareness tool designed to highlight patterns that may need further attention.
Learn & Act:
After your assessment, the app connects you to:
• Research-backed neuromuscular training programs.
• Articles and videos to improve movement control.
• Local or virtual clinics and professionals for further support.
Quick. Easy. Insightful.
• All you need is space to jump, a smartphone, and a few minutes.
You’ll get feedback that helps you take the next step — whether that’s better training, safer habits, or further conversation with your coach or clinician.
Disclaimer:
This app is not intended to diagnose injuries or provide medical treatment. It is a performance screening tool to help identify movement trends and provide educational resources. Always consult a healthcare provider before starting a new training or rehab program.
