Runeasi Possibilities

Runeasi is a revolutionary wearable 3D gait analysis system that can be done anywhere and anytime. There’s no need for sophisticated treadmill for standardized assessments, as Runeasi technology opens doors to analyze real-world settings.

Designed not only for runners aiming to improve running technique, boost performance, and prevent or recover from injuries, but also as an invaluable tool for objective progress tracking and building confidence in post-operative rehabilitation.

Runeasi offers numerous benefits, including:

  • Access to high-quality kinetic data validated by the gold standard.
  • Streamlining assessments to fit seamlessly into daily practice.
  • Offering personalized recommendations to target and improve the weak links.
  • Providing objective data and reporting to show progress to your clients, improving training compliance.
  • Utilizing Runeasi Running Quality as an effective marketing tool to attract new clients.

Runeasi offers numerous benefits, including:

  • Receiving objective data to identify trainable weaknesses.
  • Receiving clear training guidelines to enhance their biomechanical profile.
  • Gaining a better understanding of their running technique through real-time biofeedback.
  • Ability to measure progress after completing a training program.

Here’s a preview of how you can enhance specific key parameters:

Yes. Runeasi is built upon a decade of published research collaboration between KU Leuven and Stellenbosch University. Our pelvic accelerometry has undergone validation against the gold standard for measuring whole-body kinetics. For further details, explore our resources here or request our scientific background sheet for a deeper dive into the research.

While 2D video analysis reveals how you move, Runeasi delves deeper to explain how those movements impact your body. It provides insights into how your movement patterns influence crucial biomechanical factors linked to injury risk and running efficiency.

Runeasi offers a comprehensive understanding of how we stress our bodies, serving as a valuable tool for our customers. By combining this information with observations from 2D video images, they gain clarity on why individuals may encounter difficulties in specific areas.

Moreover, in addition to this enhanced analysis, we furnish detailed information about each step you take. Recognizing the uniqueness of every step contributes to a holistic understanding of your movement. With our solution, you can now accurately assess biomechanical fatigue.

Runeasi is not limited to runners; it’s versatile and applicable to various sports involving running, including post-operative care such as Post-ACL rehabilitation. Incorporating Runeasi into rehabilitation and prevention offers numerous benefits, including:

  • Identifying weaknesses in the kinetic chain of your clients/patients/athletes
  • Assessing functional progress in rehabilitation programs
  • Determining optimal training speeds for return to running
  • Detecting biomechanical fatigue during a training session
  • Providing real-time biofeedback to correct compensatory gait strategies

These are just a few of the possibilities when utilizing Runeasi in the rehabilitation process.

No. Runeasi is designed to accommodate to a wide range of subjects, from recreational athletes and runners to elite/Olympic-level competitors.

Absolutely! Runeasi has carefully chosen its parameters to enable assessments for rehabilitation, prevention, and performance purposes. Moreover, enhancing your running efficiency through gait re-training and targeted strength training not only boosts resilience against injuries but also enhances performance.

Yes. Thanks to its ample storage capacity, the sensor can record 3D running data throughout long runs, interval sessions, and races. Once you initiate the assessment, you can run as far and as long as you wish, all without the requirement of a connected tablet.

Runeasi Technology

Runeasi is an advanced software technology that computes essential biomechanical components using pelvic accelerometry data from an IMU device (Inertial Measurement Unit). To ensure the acquisition of high-quality and reliable data, we have developed a specialized running belt featuring anti-slip material to eliminate motion artifacts. Explore further details about our hardware and software on our Science and Technology page.

To accurately capture whole-body kinetics, it’s essential to measure close to your body’s center of mass (COM). Over the past ten years of research, we’ve proven that using pelvic accelerometry with our specially designed running belt is effective. This method provides a practical alternative to force-instrumented treadmills, making it useful for various purposes.

Our innovative algorithms allow for the precise detection of left-to-right differences without the need for multiple sensors. This not only reduces setup friction but also streamlines data synchronization, eliminating the requirement of additional sensors on shoes or shins.

Moreover, our approach offers invaluable insights into how effectively lower limbs absorb shock—a crucial metric in assessing and enhancing patient rehabilitation progress. By providing this detailed biomechanical feedback, we empower practitioners to optimize rehabilitation protocols and encourage meaningful functional improvements.

Yes. Thanks to its ample storage capacity, the sensor can record 3D running data throughout long runs, interval sessions, and races with a ‘remote recording‘. Once you initiate the assessment, you can run as far and as long as you wish, all without the requirement of a connected tablet.

Yes, with the ‘real-time biofeedback‘ mode, you can walk or run while having the tablet positioned in front of you. This setup enables you to make real-time gait adjustments with every step you take.

Runeasi stands out as the fastest solution available on the market. With a setup time of less than 30 seconds, you can swiftly position the sensor and start your running assessment. This efficiency makes it an invaluable tool for daily practice, where time is of the essence and every moment counts.

Our advanced reports can be automatically generated right after your assessment. Whether it’s a session report or a speed-comparison report, delivering the data to your client takes only seconds.

Yes, both the sensor and the belt, made of neoprene material, are waterproof.

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.
