It’s a well-established fact that the body heals better and faster with a structured therapy and exercise program. But often with lower extremity (hips, legs, ankles) injuries or fractures, the full weight of the body can literally be too much to bear. AlterG ® can help:

Alter G Testimonials

“The new Alter G anti-gravity treadmill is amazing! I think it must be what it is like running in heaven! If you are an injured runner, you have got to check it out. Thank you Chris for being the best most patient PT ever. Thanks to you I will be running again in no time. Here is to standing on one foot!”


–Sally W.

“I heard about Chris Kopp from my eye doctor.  I am a dedicated runner and the fact that Chris specializes in runners really appealed to me.  During our initial meeting, he asked questions about me and examined the different movements of my legs, ankles, and hips.  He quickly narrowed my problem down to the lack of strength and flexibility in my hips.  Over the course of four weeks, he showed me different exercises to do and printed forms for me to take home to also work on at home.  This homework is what really helped me.  The clinic time lasts 30 minutes to one hour, but I can work out at home anytime for as long as possible.  Eventually Chris allowed me to run on the AlterG.  I was nervous at first but he encouraged me to play with the machine, reinforcing that I could not hurt it.  The machine was great and I will be back for more.  Chris is the man and Premier is the place to be”
