I do have re-occurring injuries. I had the opportunity to be treated by Chris Mortensen – the main benefit for me was being able to stretch further – improve my function mainly of my hips.

I have been using my device on my ruptured Patella tendon. I have found the treatment to be highly and immediately effective. This treatment has really improved my recovery.

Your service, ethics, and prompt attention and answers to the many questions have been greatly appreciated.As you know, I LOVE, LOVE, LOVE, my Sanakey!   I have become quite possessive about it and told the kids they can come over and use it here, that way when WE need it, it’s here!

Peter and the team at Key Health Technology are knowledgeable and highly effective in supporting their practitioners and clients who purchase any of the Key devices. You will never be left alone to fend for yourself and can always ask questions.
