About Us

At TheraSonic, we believe that everyone deserves to move through life without pain holding them back. Our mission is simple: to provide safe, effective, and easy-to-use therapy devices that bring real relief, from the comfort of home.

We created the TheraSonic Knee Massager because we saw how many people, from active adults to aging parents, were struggling with stiff joints, chronic knee pain, and limited mobility. Long clinic wait times, expensive treatments, and daily discomfort were getting in the way of doing what they love.

So we designed a smarter solution.
Combining red light therapy, soothing heat, and vibration massage, TheraSonic delivers targeted knee relief in just 20 minutes a day. It’s wireless, hands-free, and built for real people with real lives, whether you're recovering from an injury, managing arthritis, or simply want to feel more confident on your feet.

We’re proud to be a brand built on trust, comfort, and results. Backed by our 30-Day 100% Happiness Guarantee, we’re here to help you take the first step toward a life with less pain and more movement.

Thank you for being part of the TheraSonic family.
Let’s get you back to moving, living, and feeling your best.
