 UlterJ is one of the most advanced treadmill we have at our facility. It has variety of applications, mostly rehabilitating athletes after ligament injuries or it could be patients needing limited weight-bearing on lower extremities such as fractures or it could be even neurological patients requiring more training in terms of gait or learning to control their extremities. This machine works by controlling the effect of gravity, that means when you walk on this treadmill you could control the weight-bearing on your legs by decreasing the gravity as low as 20% of your body weight, that means if somebody has limited tolerance or they are following restricted weight-bearing on lower extremities, we could go safely to that percentage of weight-bearing and still have a patient to emulate and build up their strength and tolerance by controlling the weight on this treadmill.
