Overcome chronic knee pain

and regain the independence, freedom and strength of your younger years

There’s still hope!

The good news is that we have decades of research and knowledge on knee pain and how to manage and overcome it.

Since the beginning of time, the brightest minds in history have dedicated their lives to helping people treat and manage their pain.

With the right strategies and habits, overcoming pain is possible.

And that’s what you’ll get today with our physiotherapist-led Back to 25 Rehab Program.

We partnered with Mathieu Sonier, a physiotherapist with 11 years of clinical experience.

He is going to show you exactly how you can recover from knee pain with several simple yet effective exercises. No equipment needed. You don’t even have to leave your house.

Knee Clinic courses are designed to specifically address the root-cause of age-related chronic knee pain and joint degeneration.

As we age, we lose muscle mass and function. We also experience changes in our neuro-motor system, such as reduced sensorimotor coordination and lower body strength and stability.

Weakened or improperly functioning muscles place increased stress on our joints and cartilage as we move around, subjecting them to increased wear and tear and causing structural joint problems and pain.

Knee Clinic uses the Neuromuscular Physical Therapy (NPT) approach

to progressively rebuild strength in key muscle groups connected to the knee, and retrain your neuromuscular system.

With improved muscle strength and better muscle activation and coordination, we relieve pressure on the knee joints.

This in turn relieves cartilage decay, increasing joint stability and functioning and reducing knee pain.

NPT is different from traditional physiotherapy.

It focuses on quality over quantity

enhancing muscle activation through functional and proprioceptive training, rather than simply increasing reps to become stronger.

This in turn relieves cartilage decay, increasing joint stability and functioning and reducing knee pain.

This training has been proven

to relieve pain, improve function and biomechanics in the knees, as well as even reverse cartilage decay, which is the root cause of pain in conditions like osteoarthritis.

With just 6-8 weeks of consistent and deliberate NPT training, you can improve your osteoarthritis pain and reclaim your freedom and independence.

Living pain-free is possible

Rehabilitation is a journey—a lifelong process.
And to be honest: it won’t be easy.

But on the day when you finally find yourself doing the things
you could only dream of before, everything will be worth it.

You have to be patient
and take it step by step…

Don’t wait until your knees cross the line of no return, where you may have to rely on a wheelchair or walking aid to get around.

  • You have a medical condition and are advised by your doctor to avoid exercising or raising your heart rate;

  • You are not sure what the cause of the pain or inflammation is;

For many people, 25 was a time when they felt invincible.

The world was your oyster, full of opportunities and wonder.

So many things to do, see and experience. You were only limited by the number of hours in a day.

You could push your body to the limits, wake up the next morning like nothing happened. Any damage or illness would heal in a matter of days.

It all boils down to your personal choice: keep moving forward or simply drift along.

You decide.
