I have had chronic pain and spine issues for over 25 years. I've lost count of how many therapists I've seen, but it must be around a dozen.
Focus is different. Very, very different. A therapist is committed to you for your full appointment. They also have approached my issues in an entirely different way than every PT has in the past.
Lastly, I am able to only walk short distances. Focus now has the AlterG anti-gravity treadmill. This was developed by NASA and is amazing. I can get "in/on" the treadmill and set my body weight at whatever I want. I walk in the AlterG at about 50% body weight. Well, guess what? I can walk over twice as long as I would on a normal treadmill. The machine is great and so is the whole experience at Focus.
