Adductor injury football player linked to unilateral instability

By Matyáš Uzlík – Runeasi expert

In this insightful use case, provided by Matyáš Uzlík, we illustrate the importance of evaluating a football player’s loading pattern during the return-to-sport phase. Given the player’s extensive injury history, including knee and ankle ligament injuries requiring surgery, as well as meniscal and cartilage tears over four years, Matyas recognized the need for a cautious approach in gradually reintroducing the player to full training loads.

Loading pattern before injury

The football player exhibited a significant difference in dynamic stability, with lower stability on the left leg. Despite displaying reduced shock absorption on the left leg, there was a consistent observation of lower impact magnitude and shorter ground contact time. This suggests a protective gait pattern, and be therefore cautioned with going back to full training load.

Running data before injury

Despite the potential risks, the player went back to full training load with an overuse injury a few weeks later on the adductor muscles. Matyas acknowledges the importance of objective data to estimate the risks and be more cautious with this protective gait pattern.

“We’ve got to listen to these warning signs and focus on improving stability, mobility, and strength. We can’t rush this process.” Matyas also pointed out, “With Runeasi’s help, we can detect compensation strategies and keep track of how we’re progressing, making sure we’re moving forward safely and steadily.”

5. Quick comparisons

Compare pre-post data to show intervention effects on the movement quality. 


1. No motion artifacts. The Runeasi belt is secured tightly against the body and the skin to capture the actual movements of the body’s center of mass. Attaching or clipping the sensor directly to the pants would allow the sensor to wobble from side to side (i.e., measuring the wobbling of the pants, and not the human body.

2.  Easy to standardize the sensor’s positioning. The Runeasi belt makes it easy to consistently position the sensor close to the center of mass. Attaching the sensor directly to the pants would dramatically affect the reliability of the outputs as the height and tightness of the pants will affect the results. Moreover, these pants attachments often shift sideways while running which further decreases the data quality. 

 3. Comfortable to wear.  Hundreds of runners confirmed that they immediately forget about our belt while running. This allows them to move without any restrictions and allows us to capture movements that are representative of a client’s true biomechanics.
