“Our goal in designing the MyoTool, was to create a tool that would reproduce as closely as possible the soft tissue and joint mobilization techniques that we use in the clinic.  These techniques have been proven to be effective and can now be performed at home, whenever needed, using the MyoTool.”

Matthew Johansen PT

Matthew graduated with his Masters in Physical Therapy degree from the University of Utah in 1999.  He worked in diverse patient treatment settings, including outpatient orthopedics, neurological rehabilitation, acute care, and wound care prior to specializing in orthopedic and manual physical therapy.  He participated in three year-long manual therapy courses and acquired training in Australian, Norwegian, McKenzie, and Osteopathic approaches.

“While inventing the Myotool, John and I spent countless hours modifying and improving its design.  The shape of the MyoTool and the size, position, and configuration of each knob is the result of these efforts and allows an incredibly versatile and individualized way to treat the stiffness, discomfort, and stress in our bodies.”

In January 2019 Mathew Johansen sold his half of the Myotool business back to John Seivert. John is now sole owner of the myotool.
