Prehabilitation: The Rehab You Do Before You Get Hurt

Every week I treat athletes who could have avoided my clinic entirely. The ACL tear that started as a weak glute. The shoulder injury preceded by months of poor thoracic mobility. The chronic ankle sprains rooted in a proprioceptive deficit that a 30-second balance test would have caught. In my clinical experience, the majority of non-contact youth sports injuries have precursors — identifiable movement deficits that, if addressed proactively, would have prevented the injury altogether. That proactive process has a name: prehabilitation.

Prehab Is Not Just Injury Prevention — It's a Clinical Mindset

Let me distinguish prehabilitation from general injury prevention programs like the FIFA 11+ or ACL-focused neuromuscular training. Those programs are excellent, but they target specific injury types with predetermined exercise protocols. Prehabilitation is different — it starts with assessment. We screen the individual athlete for their specific weaknesses, asymmetries, and movement deficits, then design a targeted program to address what we find. It's personalized prevention, not one-size-fits-all.

The evidence supporting this approach is robust. A landmark 2014 systematic review by Lauersen et al. analyzing over 25,000 participants found that exercise-based injury prevention programs reduced injury rates by 30-50% across all sports and injury types. Strength training alone reduced injuries by an average of 68%. The key finding: programs that included screening and individualization produced the best outcomes.

The FMS Simplified for Coaches

The Functional Movement Screen (FMS), developed by Cook et al. , is a validated screening tool that identifies movement deficits in seven fundamental patterns. The full FMS requires certification and takes 15-20 minutes per athlete. But coaches can use three simplified screens that capture the most critical information:

1. Deep squat. Have the athlete hold a dowel overhead with arms fully extended, feet shoulder-width apart, and squat as low as possible. Watch for: heels rising, knees caving inward, excessive forward lean, inability to keep arms overhead. These indicate ankle mobility restrictions, hip weakness, or core stability deficits.
2. Single-leg balance (eyes closed). Stand on one leg, close eyes, hold for 20 seconds. This tests proprioception — the nervous system's awareness of joint position. Athletes who can't hold 15 seconds with eyes closed have a significantly elevated risk of lower-limb injury, particularly ankle sprains.
3. Inline lunge. Place the front foot on a line, rear foot directly behind it, and lower into a lunge. Watch for: lateral trunk lean, knee valgus, loss of balance. This pattern reveals hip/glute deficits that predict knee and hip injuries.

The "Big 3" Prehab Areas Every Youth Athlete Needs

After screening thousands of young athletes, three areas consistently emerge as the universal weak links, regardless of sport:

1. Ankle stability and proprioception. The ankle is the foundation of the kinetic chain. Deficits here cascade upward — poor ankle control leads to compensatory knee loading, which eventually leads to hip and back issues. Prehab focus: single-leg balance progressions, ankle alphabet exercises, and band-resisted ankle eversion work.

2. Hip and glute activation. The gluteus medius is arguably the most important muscle in youth sport injury prevention. When it's weak or inhibited — which it is in the majority of desk-sitting adolescents — the knee drops inward during landing and cutting, creating the valgus position that tears ACLs and damages menisci. Prehab focus: clamshells, banded lateral walks, single-leg hip bridges, and Copenhagen adductor holds.

3. Thoracic spine mobility. A stiff upper back forces the shoulder and lumbar spine to compensate, leading to shoulder impingement in overhead sports and low back pain in rotational sports. Most youth athletes have thoracic mobility restricted by hours of hunching over devices. Prehab focus: thoracic rotations on all fours, foam roller extensions, and wall angels.

The 10-Minute Daily Prehab Routine

Here's a protocol I use with my youth athletes. It requires no equipment beyond a resistance band and takes 10 minutes:

1. Single-leg balance, eyes closed — 3 x 20 seconds each side
2. Banded lateral walks — 2 x 10 steps each direction
3. Single-leg hip bridge — 2 x 8 each side
4. Thoracic rotation on all fours — 2 x 8 each side
5. Banded ankle eversion
