The New Standard in Strength Testing
- Faster than a handheld dynamometer.
- More accurate than a blood pressure cuff.
- Measure adduction and abduction in the same test.

“We use the NordBord and ForceFrame for preseason screening, weekly testing, training and rehab, and use the data we get from them in combination with our other key metrics such as running load and flexibility to inform our weekly training plans.”

Why do you use Vald Performance systems?
There are a few key reasons why we choose to use the NordBord and Forceframe:
Real-Time Biofeedback: Feedback is critical for educating our players and helping them understand their bodies, and ScoreBord allows us to provide this in a number of different areas.
Objective Data: We also rely more and more on data to drive our decisions, and the NordBord and ForceFrame provide us with objective data in several key areas of performance.
Ultimately, what I try to drill into my staff is that collecting data is all well and good, but only if we do something with it. The NordBord and ForceFrame give us data that we put to use every day.
How do you use Vald Performance systems at GWS?
We use the NordBord and ForceFrame in a few different ways:
Screening: Team-wide Nordic / glute-ham (NordBord) and adduction/abduction (ForceFrame) testing occurs at start/end of preseason, plus a few timepoints in-season.
Training: If a player has an imbalance, we’ll use ScoreBord to provide them real-time feedback as they train, helping them appreciate why they’re doing what we’re asking them to do.
Rehabilitation: We use the NordBord not only for hamstring injury rehab, but also for other injuries (for example, even ankle sprains!) where the athlete may be at risk of losing hamstring strength as a by-product of sitting on the sidelines.
Weekly Testing Battery: The ForceFrame forms part of our weekly tesing battery – we have players perform a ForceFrame 45° adduction/abduction test along with a Thomas Test, active leg raise, slump test and knee-to-wall test. In the ForceFrame test we’re looking primarily at peak force and percentage imbalance between limbs.
Are there specific numbers you’re looking for in your testing?
We primarily look to the published literature (for example, for the NordBord we reference Opar et al, 2015) to inform the targets we set for our players. We work off a couple of principles to ensure we’re setting smart, realistic guidelines:
Team-Wide: We want to see all our players above the published risk thresholds for hamstring and groin strength, and we add +10% to these numbers as we like to set the bar for our players a little bit higher.
Intra-Player: We also compare each player to themselves over time, and reference back to their preseason screening results as a baseline. We consider +/- 10% variation to be ok, and a drop of more than 10% is something we’ll take a look at.
Do you look for interactions between Vald Performance systems and other data you collect?
We would never intervene or change our plans based on one metric alone, so we’re constantly montioring how changes in our NordBord and ForceFrame results correlate with some of our other key metrics, such as:
running loads, wellness reports, and any existing injury concerns
