How downhills could be triggering your Runner's knee (Patellofemoral Pain Syndrome)

Understanding the importance of shock attenuation and impact asymmetry

Patellofemoral Pain Syndrome (PFPS), commonly known as ‘runner’s knee’, is a prevalent overuse injury that regularly results in relapses after returning to running. Downhill running is a major risk factor in the incidence of patellofemoral pain. Research has shown that patellofemoral stress is a lot higher in downhill running compared to flat-ground and uphill running (French et al. 2018). Unfortunately, we can’t always avoid a hill when the terrain is various. Therefore, learning how to run downhill has its place in the return to sports trajectory of a client with patellofemoral pain.

Can you see in the graph below how the runner struggles to attenuate the shock (i.e., absorb the load) on his injured (right) leg when he runs down the hill? Assessing and improving his descent will be one of the key factors to reassure the runner of a habit he can change and help him succeed!

5 rEASONS TO USE OUR APP

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

2. individual recommendations

Get individual training and cueing recommendations to improve your client’s weakest link.

3. Real-time feedback

Engage your clients through visual gamification and watch how they self-optimize to your verbal cues.

 

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. 

3 REASONS TO CAPTURE DATA USING THE RUNEASI BELT

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.
