"I used BACK4 to treat Red Bull Cliff Diving athletes. I’ve had incredible results with it, both in preparation and in recovery. Some of these extreme divers have named it the “magic machine”! The ability to mix the currents and work on several areas makes me much more effective.

At my practice, I use it for all types of patients: ortho, elderly, athletes.

Apart from the design which is superb, this ability to mix and play with the currents is great."
