  • The high-end fitness recovery devices known as Theraguns and their specialized massager tips are at the center of a dispute between two former friends known as “Dr. Mike” and “Dr. Jason.” In a lawsuit filed on Tuesday in California, chiropractor Michael Wasilisin, known to his followers as Dr. Mike with MoveU, accused the company of leaving his name off two patents for thumb and wedge massage tips that he designed to deal with deep muscle knots in people’s lower backs. Therabody’s general counsel told Fortune in a statement the company believes the claims in the lawsuit are without merit.  

It started as a handshake deal between two guys who both believed in helping people deal with chronic pain, said Michael Wasilisin, known as Dr. Mike of MoveU on social media. Initially, after Wasilisin met and talked with Therabody founder and chiropractor Jason Wersland, the deal was for a boat, Wasilisin told Fortune.
