The ZeroG robotic system allows patients to practice functional activities safely, with biofeedback that provides vital motivation and cues. The technology can compensate for a patient’s poor coordination or weakness while lowering the risk of injury to both the patient and the therapist. Besides helping patients rehab after orthopedic surgery, the ZeroG also has applications for patients who have had a stroke, spinal cord injury, traumatic brain injury, amputation, cerebral palsy or multiple sclerosis. The ZeroG technology is used in about 77 of the leading rehab hospitals in the United States, according to Michael Ranberger, president and owner of Evergreen. “It’s pretty unusual for ZeroG to be in a post-acute facility like ours, but Evergreen does a lot of return-to-home rehab,” said Ranberger.
