Former NHL forward T.J. Oshie has shed new light on the trade that sent him from the St. Louis Blues to the Washington Capitals, revealing an unexpected reason behind the blockbuster move.

Speaking on the Spittin’ Chiclets podcast, Oshie explained that his use of Accelerated Recovery Performance (ARP)—an electrotherapy tool that combines electrical currents with active range-of-motion exercises—may have played a role in the Blues’ decision to move him.

“I actually got into it because I was so injured,” Oshie said. Noting that he was lifting heavy weights in the gym and his back was in rough shape as a result, “I used it before one game and my back pain disappeared.”
