019 - Predicting Re-Injury After Return to Duty: Who’s Actually Ready?



38% of service members sustained another injury within a year of being medically cleared.


The Data-Proven Red Flags for Re-Injury

  • Poor movement & balance scores (Y-Balance, Functional Movement Screen, Triple Hop Test).

  • Slower 2-mile run timeseach extra minute = higher injury risk.

  • Asymmetries in ankle dorsiflexion & weight-carrying ability.

  • Pain during movement assessments.

  • Higher BMI, smoking, & prior deployments = increased risk.


Tactical Fixes: How to Reduce Re-Injury & Optimize Return-to-Duty

1. Integrate Injury Risk Screening Before Clearance

  • Use Y-Balance, FMS & Triple Hop Tests to flag mobility & strength deficits.

  • Identify asymmetries & inefficiencies before re-entry.

  • Slower run times = warning sign, not just a conditioning issue.

2. Strength & Mobility Interventions for High-Risk Personnel

  • Fix ankle dorsiflexion & balance deficits with targeted mobility drills.

  • Increase load-bearing endurance with structured carry-based strength training.

  • Shift from time-based clearance to performance-based reconditioning.

3. Monitor & Adjust Clearance Based on Performance Data

  • Reassess movement & strength metrics throughout the return process.

  • Use biomechanical data to refine injury prediction models.

  • Adopt phased reintegration instead of immediate full clearance.

Thick Necks, Strong Foundations, No Weak Links

A healed injury isn’t the same as being mission-ready. A checklist clearance doesn’t guarantee performance. If we’re not screening for movement quality, we’re sending warfighters back in unprepared.

  • Screen movement, not just medical history.

  • Train to eliminate asymmetries before they cause injuries.

  • Return-to-duty should be a performance standard, not just a timeline.

A thick neck with weak movement patterns is an injury waiting to happen.

Fix The Foundation. Stay Thick.
