Whether you’re a seasoned competitive marathoner, or just lacing up your shoes for the first time, understanding your running style and making necessary improvements can significantly improve your running experience and prevent those frustrating sports injuries. A Running Gait Analysis is a key service that allows you to measure your running form, understand your unique gait, and reduce the risk of injury. In the first part of this series, we discussed what Running Gait Analysis is, how it is usually performed, and the benefits of doing a Running Gait Analysis. In this second part, we will look at the Runeasi 3D technology we use, its benefits, and the unique and unparalleled insights it delivers. 

What is Runeasi?

Runeasi is a revolutionary 3D gait analysis instrument that uses a scientifically validated, state-of-the-art biomechanics sensor to track the acceleration of your body’s centre of mass during running or walking (Fig 1). By doing so, Runeasi captures the impact your body is subject to during running (Fig 2) and uses AI technology to assess how your body responds to this impact. Through this process, it detects issues such as poor movement control, instability, overload and asymmetry.

Additionally, this AI technology will give you an overall Running Quality Score to grade your running. It will give specific recommendations on exercises and running techniques to improve your running quality. At Podiatry Quest, a full report with the findings and recommendations will be provided at the end of the session. 

Figure 3:  To grade your running, a holistic Running Quality Score synthesises all the most essential biomechanical components and transcribes it as weakest links.

Runeasi provides real-time objective data that measures a runner’s weakest links that are invisible to the naked eye (Figure 4). This allows data-driven personalised training recommendations to be made and progress to be measured. All of this is interpreted and synthesised into a convenient, easy-to-understand report for you.

3 Components of Runeasi

Runeasi’s Running Quality Score comprises three biomechanical components. This allows you to dissect your running form and understand your weakest links accurately. They are: 1) dynamic stability, 2) impact loading, and 3) symmetry 

1. Dynamic stability

Dynamic stability represents the amount of side-to-side hip movement during the ground contact phase of running. It captures the amount of energy not contributing to forward movement. 

A low dynamic stability score represents an inefficient running gait that also increases the risk of injury. Recent research showed that this parameter is linked to energy cost of running (Schutte 2018) and is an important biomechanical risk factor in overuse injuries (Pla et al. 2021)

2. Impact loading 

Impact loading is measured by the amount of force and the time this force takes to reach your lower back immediately after the foot hits the ground. 

The magnitude of impact is the peak value of this force and is the indicator of the total amount of running load.

Impact duration is the amount of time that this force takes to reach your lower back. It demonstrates the rate of loading and explains how well load is absorbed by the lower legs. 

Both parameters are strongly linked to patients with running-related injuries (Burke et al. 2022) and are most accurate to measure cumulative impact load (Vanwanseele et al. 2020).

3. Gait Symmetry 

Measuring gait asymmetry is very important for any runner. Movement dysfunctions during running and walking can prolong for years with an injury (White et al. 2013; Thomson et al. 2018)

Gait asymmetry is directly linked with energy cost in running gait (Melo et al. 2020)
