Your kid just passed their sports physical. Heart sounds fine, blood pressure is normal, growth is on track — cleared to play. That form tells you your athlete is healthy enough for sports. It doesn’t tell you whether their shoulder rotates evenly, whether last year’s ankle sprain ever fully healed, or whether a growth spurt has thrown off the strength balance between their hips and knees.
Those are the things that actually cause the injuries you see mid-season: the non-contact ACL tear in October, the shoulder that finally gives out in week six, the hamstring that pulls again for the third time. A preseason movement screen is built to find that stuff before the season does. It takes about 20 minutes.
Why a Sports Physical Alone Doesn’t Catch Everything
A sports physical is a medical clearance, not a performance evaluation. A doctor is checking for conditions that would make it unsafe to play at all — heart abnormalities, uncontrolled asthma, unresolved concussion symptoms. That’s essential work, and it should never be skipped.
But a physical isn’t designed to assess how your athlete moves. It won’t tell you if they land a jump with their knee caving inward, if one leg is noticeably weaker than the other, or if an old injury changed the way they run without anyone noticing. Those are mechanical issues, and they need a mechanical evaluation — not a stethoscope.
What a Real Preseason Movement Screen Actually Looks At
A functional movement screen looks at how your athlete’s body actually performs under load, not just at rest. At our 14 locations across Texas, that typically includes:
- Squat, lunge, and single-leg balance patterns, watched for compensation or instability
- Side-to-side strength comparisons at the hips, knees, shoulders, and core
- Range of motion in joints that took a hit from a prior injury
- Landing and jumping mechanics for field, court, and gym sports
- A quick history review flagging past injuries, recent growth spurts, and training load
None of it requires imaging or needles. It’s hands-on, it’s fast, and it gives you a clear picture of where your athlete stands going into the season.
Common Red Flags Screening Catches Before They Become Injuries
Most of what shows up in a screen isn’t dramatic. It’s small, fixable stuff that gets ignored until it isn’t small anymore.
- A quad noticeably stronger than the hamstring on the same leg — a classic setup for a hamstring strain
- A knee that drifts inward on landing — one of the more consistent warning signs tied to ACL injuries
- Limited ankle mobility on the side of a prior sprain, months after the athlete says it “feels fine”
- A hip or shoulder that hasn’t caught up in strength after a fast growth spurt
- Compensation patterns that developed while an athlete was favoring an old injury, and never went away
None of these show up on a stethoscope. All of them show up in 20 minutes of movement testing.
Who Benefits Most From Preseason Screening
Every athlete benefits from knowing their baseline, but a few groups have the most to gain:
- Athletes coming back from a prior injury. “Fine” and “fully recovered” aren’t the same thing. A screen tests strength and control directly instead of relying on how a joint feels.
- Athletes in the middle of a growth spurt. Bones lengthen faster than muscles and tendons can keep up, which temporarily throws off strength ratios and coordination — a well-known driver of overuse injuries in early and mid-teens.
- Athletes new to a sport or a higher level of competition. New movement demands expose gaps that didn’t matter in a less demanding sport or division.
If your athlete falls into any of these categories, screening matters even more than usual — it’s the difference between guessing and knowing.
What Happens If Something Turns Up
Finding an issue isn’t a diagnosis and it isn’t a reason to panic. Most red flags caught in a preseason screen are addressed with a targeted strength or mobility plan — a handful of specific exercises aimed at the exact imbalance found, not a generic program. Most athletes can start those in the weeks before the season even opens, working the fix in alongside normal training.
Occasionally a screen points to something that needs a closer look before clearance — a joint that’s still guarding from an old injury, for example. In that case, you get a straightforward next step, not a runaround. Families near our Austin, DFW, and Houston clinics can usually get a screen and a follow-up plan finished well before the first practice.
A physical answers one question: is it safe for your athlete to play? A movement screen answers the one that actually determines their season: are they set up to play without breaking down? Both take less time than a single practice. Only one of them is optional right now — and it shouldn’t be.
