Behind the Scenes: Our Initial Assessment of Runeasi Running Gait Analysis

 by AJ Cohen (Up & Running)

1. Introduction

Welcome to this presentation featuring our Runeasi Expert, AJ Cohen, from Up & Running in the United States. In this video, join us as AJ conducts his initial assessment with Runeasi and explores the exciting possibilities with runner Joey.👇

2. My first Test with the Runeasi Platform: Evaluating Running Metrics

“Welcome, everyone! In today’s video, we’re testing the Runeasi platform, an exciting tool from Belgium. It combines a 3D Gait lab, a sophisticated device, and powerful software that allows us to measure various running metrics. These metrics include impact magnitude, impact duration, dynamic stability, ground contact time, and more. This data, in conjunction with clinical reasoning, can help us better understand injuries and aid in the recovery process. Join us as we explore this technology for the first time!”

Introducing Joey, Our Talented Runner:

“Allow me to introduce Joey, an exceptional runner with an impressive 70-minute half-marathon personal record. According to the Runeasi chart, Joey falls into the category of a high-level runner, scoring between 80 and 90, just shy of the Olympic-level runners😉. Today, we’re curious to see where he falls within this range. Let’s dive in!”

Preparing the running test (Belt placement)
Proper belt placement for accurate data

“With Joey all warmed up, we’re ready to start the test. As he runs, the device captures data and provides real-time feedback. Initially, we noticed that Joey’s impact duration was shorter than optimal. Ideally, the foot should spend more time on the ground, allowing the body to absorb forces gradually. However, as the data accumulates, the graph starts turning greener, indicating improvement. Dynamic stability looks good, while impact magnitude shows a slight difference between his legs. Joey adjusts his speed, resulting in increased impact magnitude. It’s important to note that impact duration on the right side still lags slightly, causing some asymmetry.”

Assessing Joey's Running quality and identifying his weakest link

“To address the impact duration issue, we decided to provide Joey with live biofeedback. The device displays new data points every five seconds, allowing Joey to make real-time adjustments and improve his impact duration. While this is just a test, the technology shows promising potential.”

3. Evaluating the Results and Generating a Report

“Based on the data gathered during this session, Joey achieved a running quality score of 80, indicating a solid performance. The system identifies symmetry as Joey’s weak link, primarily due to the sub-optimal impact duration on the right side. This observation aligns with Joey’s own feelings and physical condition leading up to the test.

By examining the details, we can generate a comprehensive report through the app. The report explains impact duration and suggests incorporating plyometric training to address this specific issue. It provides a framework of recommendations, including running drills, tips, and cues for Joey to practice during his treadmill sessions. This personalized approach aims to enhance Joey’s running score and overall performance.”

Turning Data into Action: Runeasi's Training Recommendations

4. Looking forward to doing more assessments with Runeasi

Finally, we showcase the technology in action, demonstrating how the TV and treadmill work together to provide live feedback during training sessions. We’re thrilled about the possibilities this technology offers and are excited to explore it further. That concludes our teaser for today. Thank you for joining us on this journey with Runeasi. Stay tuned for more exciting updates!

1. Global movement quality

Track and improve your client’s Runeasi running quality. Identify their weakest link with our advanced visualisation.

2. individual recommendations

3. Real-time feedback


4. Session trends

Learn more about your client’s running quality during daily training. Our session trends show when and where the quality drops with fatigue.

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.
