The versatile GlideTrak High Percentage Unweighting System provides partial to full body unweighting, and meets the doctors orders for: non-weight bearing, touch down weight bearing, partial (50% or less) weight bearing, or weight bearing as tolerating. It removes impact to allow pain-free, functional exercise and gait training over any treadmill. The system is ideal form sports and orthopedic therapy, neurological rehabilitation, fitness, and cross training, geriatric conditions, weight los and adaptive sport training. The standard shoulder harness provides safe and secure exercise for balanced challenged patients. An optional balance harness upgrade offers added security, comfort and postural control. It also allows the option for safe, regular treadmill use with or without the GlideTrak saddle assembly.
