Support our study that aims to improve knee joint health

Take part in this study comparing different foot orientations on knee joints during daily activities. You'll receive a biomechanical report for taking part.

How foot position during activities can affect your knee joint health

This is the first study comparing the effect of different foot orientation on knee joint biomechanics during a range of daily activities. Our researchers are using an advanced camera-based motion capture system to examine this.


The way in which we move influences the load placed on our joints and the progression of joint degeneration problems in later life. There is the potential that movement pattern changes such as altering foot orientation during daily activities (such as walking, sit-to-stand, stair climbing for example) could impact knee joint loading, which might reduce damage to joints and contribute to overall wellbeing and quality of life.

What's involved in the study

You will need to visit to the Applied Biomechanics Suite (ABS), at the University of Bath to take part.

The procedures involve:

  • body measurement (10 minutes)
  • preparation for data collection through attachment of motion analysis markers (20 minutes)
  • exercises trials (around 1.5 hours)

During the exercise trials, you will perform sit-to-stand, walking, and stair climbing, in three different foot orientations (parallel, toe-in, and toe-out). The markers attached on your body will be captured and recorded during trials by the motion capture system for analysis.

We will record video of your legs during the exercises. It will not be possible to identify you from the video. Videos and all data will be stored securely.

A copy of the end of study summary will be provided to you. We will explain the results of some of the measurements so you can find out more about your biomechanical feedback.

Eligibility

To take part in this research you must:

  • be aged between 45 and 65 years
  • be without knee osteoarthritis or other knee pain
  • not use orthotics

What you'll get for taking part

You will be given a report of your test results so you know more about your biomechanical feedback during daily activities.

The foot position and corresponding knee joint loading will be revealed in the feedback, which can provide a better insight of how to optimise your movement pattern in order to reduce loading during daily activities. These are specialist measures that would be difficult and expensive to access outside of a research setting.

Your personal information

Only the research team will have access to information that you provide. Any of your data collected or accessed for this study will be handled with the strictest confidence and in line with the General Data Protection Regulation.

You will not be identifiable in any publications. Your details will be stored securely on the University of Bath secure server and will only be accessible by the research team. This study has received ethical approval.
