Revolutionising Knee Care at Home: How MAI Motion Lets You Assess Your Knees Using Just Your Phone Camera

Introduction

Monitoring your knee health is more important than ever, whether you're recovering from an injury or simply aiming to stay active as you age. But frequent clinic visits can be inconvenient, time-consuming, and expensive. Enter MAI Motion—an innovative technology that empowers you to assess your knee function right at home, using just your smartphone's camera. In this article, we’ll show you how MAI Motion makes knee self-assessment easy, affordable, and effective, so you can confidently take charge of your knee health.

What Is MAI Motion and How Does Marker-less Motion Capture Work?

MAI Motion uses what’s known as marker-less motion capture—a smart way to track your body’s movements without attaching any sensors or sticky markers. Traditionally, motion capture systems relied on placing reflective markers all over your joints, which required specialized equipment and professional setup. MAI Motion changes the game by using your phone’s built-in camera to record a video of you performing a simple movement, such as standing up and sitting down. The software then analyzes your movements to assess how well your knees are working. Research has shown that marker-less motion capture can reliably measure joint biomechanics, offering a convenient and affordable alternative to older systems. And since you can repeat the test whenever you want, you’ll get consistent, dependable results every time.

How MAI Motion Helps with Knee Care

The science behind MAI Motion is solid. Studies have found that just three repetitions of a sit-to-stand test are enough to produce accurate knee joint measurements—so you don’t need to tire yourself out with longer tests. This efficiency is perfect for at-home use, helping reduce fatigue and increasing the consistency of results. Reliable, repeatable tests allow you to track changes in your knee function over time and monitor your progress or recovery with confidence. MAI Motion brings meaningful, research-backed guidance straight to your living room, making it easier than ever to stay proactive about your knee health.

A Closer Look at Marker-less Motion Capture

So, how does this technology really work? When you record a video with your phone, MAI Motion’s advanced software analyzes the footage, tracking specific points on your leg—like your knee, hip, and ankle—as you move. The system uses powerful machine learning algorithms to reconstruct the three-dimensional movement of your knee from a simple two-dimensional video. This allows MAI Motion to provide you with a detailed, accurate picture of how your knee moves. The result? Reliable feedback you can trust, all from your own home.

How to Perform a Knee Self-Assessment at Home

Ready to try MAI Motion? Here’s a step-by-step guide to getting started:

1. Choose a Suitable Spot: Select a well-lit room with a plain background. Good lighting ensures the camera can clearly capture your movements—avoid harsh shadows or glare.
2. Set Up Your Phone: Place your phone on a stable surface or a tripod about one metre away, at knee height, and positioned to your side.
3. Wear Fitted Clothing: Opt for snug clothing so your leg movements are easy for the camera to detect—baggy clothes can make the analysis less accurate.
4. Perform the Sit-to-Stand Test: Sit on a standard chair (without armrests), stand up fully, and then sit back down again. Repeat this three times at a comfortable, steady pace.
5. Record Your Movement: Use your phone’s camera app or the MAI Motion app to film the entire sequence from start to finish.
6. Upload and Get Feedback: Follow the app’s instructions to upload your video. The system will analyze your movement and provide you with clear feedback about your knee function.

By following these simple steps, you’ll be able to carry out precise, repeatable assessments and gain valuable insights into your knee health.

The Benefits—and What to Keep in Mind

Using MAI Motion at home brings a host of benefits. It makes knee monitoring accessible to anyone with a smartphone, saving you time and money on clinic appointments. There are no sensors or complicated setups to worry about—just use your phone. MAI Motion makes it easy to check your knee function regularly so you can catch any changes early and stay on top of your well-being.

However, remember that self-assessment tools like MAI Motion are not meant to replace professional medical advice. If you notice persistent pain, swelling, or significant changes in how your knee moves, it’s best to consult a healthcare provider. Think of MAI Motion as a smart tool to help you stay informed and proactive—always in partnership with your healthcare team.
