Is the discovery call free?

Yes. The discovery call is completely free, takes about 15-20 minutes, and there is no pressure to book further care. It is how we make sure we are a good fit before you commit to anything.

Do I need a referral to see a chiropractor at RXN Performance?

No. You can come straight to us — no doctor referral or PT note needed.

Does RXN Performance take insurance?

We are an out-of-network practice, which lets us spend the full hour with you instead of rushing between rooms. We can provide a superbill you can submit to your insurance for potential reimbursement.

How is RXN Performance different from a regular chiropractor?

Traditional chiropractic often focuses on quick adjustments and short visits. RXN is built for active people who want lasting results — we combine chiropractic with movement assessment, soft-tissue work, and rehab so you do not end up back here every two weeks.

How long until I feel better?

It depends on what is going on, but most patients feel meaningful improvement within 2-4 visits. We will give you an honest timeline on the discovery visit, not a sales pitch.

Where is RXN Performance located?

We are inside Switch Fitness at 4812 Bryan St in Uptown Dallas. Parking is available and the front desk will direct you when you arrive.

What should I bring to my first visit?

Comfortable clothes you can move in (gym clothes are perfect). If you have recent imaging (X-ray, MRI), bring it. Otherwise, just yourself.

Functional Movement Screen in Dallas

The Functional Movement Screen (FMS) is a standardized assessment that grades how you move through seven fundamental patterns. It is one of the most widely used screens in sports medicine because it gives a clear, repeatable score of where your movement is strong and where it breaks down. At RXN Performance in Uptown Dallas, the FMS is part of our movement assessment offering.

What is the Functional Movement Screen?

The FMS is a seven-test screen developed by Gray Cook and Lee Burton, designed to identify movement asymmetries and limitations before they cause injury. It is widely used in professional sports, the military, and performance settings because the score has been shown to correlate with injury risk and movement efficiency.

What gets tested?

Deep Squat — full-body mobility and stability through a squat pattern
Hurdle Step — single-leg stability and stride mechanics
In-Line Lunge — split-stance stability and hip/ankle mobility
Shoulder Mobility — reciprocal shoulder range of motion
Active Straight Leg Raise — hamstring length and core control
Trunk Stability Push-Up — anterior core control under load
Rotary Stability — multi-planar core control and coordination

Who benefits from the FMS?

The FMS is especially useful for athletes preparing for a season, anyone returning to training after a layoff, lifters or runners with recurring issues they cannot pin down, and active adults who want a clear baseline of how their body moves. The score also gives us a way to re-test progress over time.

What happens after the screen?

You leave with your composite FMS score, a breakdown of which patterns scored well and which need work, and a short corrective routine targeted at your specific limitations. If you want ongoing care, we build out a treatment plan from there. If you just wanted the screen and the routine to work on independently, that is fine too.
