“The surgeon knew we were doing therapy using this device AND therapist! Chas is walking unassisted since surgery on the 13th last month and has amazing strength in his knee and leg! It works! Much more cost effect than hundreds of dollars in copays elsewhere. I am Chas’ wife E and RN 35 years. Sonya Briggs is a Physical Therapist that truly wants to make a difference! We are thankful be cause Chas has done so good we can get the other knee done before the years end. He had his post op appt last week and the PA was shocked by his progress! The video guides you through the exercises after Sonya came to eval him and teach him how to use the device! Chas is very active and has done these exercises at home! Now we go to PT at Sonya’s office to progress more with weights! Chas got the ok to drive too from the ortho PA and safely gets in and out of his truck! Thanks so much Sonya for your amazing device and therapy program! He would not be this far without you!! It has allowed him to get his life and functioning back!!
