Therabody's $330 Back Belt Combines Vibration, Heat and Light Therapy

Therabody responded by expanding beyond vibration into broader wellness categories: red light therapy, thermal contrast, pneumatic compression, and microcurrents. The company also launched Therabody University, an educational division that trains athletes, physical therapists, and everyday users on recovery protocols.

The ThermaBack LED is the latest product in that push. Velcro straps and an elastic compression strap hold the belt in place. It can be worn under or over clothing. A smartphone app lets users adjust three levels each of heat and vibration. Therabody recommends 20-minute sessions; the device shuts off automatically after that. The built-in battery lasts up to three hours between charges.

Therabody says the belt is designed not just to relieve lower-back discomfort but to increase blood flow to the treatment area and speed recovery. The device is light enough to wear while sitting or moving around the house.

The ThermaBack LED costs $329.99 on therabody.com and £249 on therabody.co.uk, where it is currently on sale for £209.

Wersland framed the product as part of a larger mission. "Do we have technologies that we can apply in modalities that make it easier for the everyday person?" he said. "We can make some really cool things that would be really amazing in the physio room for ourselves. How do we take that and translate that to the everyday person? That's really the challenge."
