It's often been said that necessity is the mother of invention. Sometimes, it's what's necessary for others that births a great idea. On this week's podcast, local physical therapists Sonya Briggs and Shehla Rooney share with us about their incredible device (invented and developed right here in Cookeville!!), GoKnee, which is revolutionizing knee replacement rehab. Along with Nikki Orazine, the three ladies operate MotusX, a private, movement based, physical therapy practice. In this episode, Sonya and Shehla shed light on the genesis of their invention, the struggles they have experienced (and help they have found) as budding entrepreneurs, and the passion they share for their patient's health which is the driving force behind all that they do. This is a must listen for anyone starting a business, one who has an invention, or those who are looking for ways to improve the health care system.
