Senator Tim Johnson (D-SD) has now checked out of the Naitonal Rehabilitation Hospital and will now receive medical care at his Washington-area home. So reports his office in a press release.

The release quotes Michael Yochelson, Director of Brain Injury Programs, as follows: "Senator Johnson is aggressive in physical therapy sessions utilizing the Lokomat® gait orthosis, a highly advanced and unique system for robotic treadmill training whereon weight bearing is shared proportionately between the Senator and the machine. As the senator progresses in his outpatient therapy on the Lokomat®, the amount of weight bearing assumed by him will gradually increase."

We're not clear on what that means, or just how long it might be until Johnson can go back to work on the Senate floor, but it sure sounds positive.
