Description of walking in the ReWalk: The ReWalk exoskeletal system requires the user to actively shift their body appropriately over their legs in order to maintain balance on the stance leg allowing the swing leg to clear the floor. This is accomplished with coordinated movements involving the upper extremity muscles in the trunk, arms, shoulder, back, neck, and head for the body to maintain balance dynamically as the system assists the legs to move in a normal walking pattern. Balance is maintained with the use of Loftstrand crutches. A mode selector, which is worn on the wrist, is used to select "walk mode" once the person is stable during standing. Following walk mode selection, the user shifts onto the left leg and slightly forward so that the right leg is offloaded. The tilting/leaning action triggers the device to swing the right leg forward and the user weight shifts so that their trunk is over the right leg as they step onto the right foot. This will then initiate the left leg to swing forward; the use weight shifts onto it and continuous walking is achieved if this coordinated weight shifting and stepping onto each leg is continued. The unit will stop walking in two ways. If the user does not shift their weight onto the front foot, then the ReWalk will time out after two seconds and return to the standing position. The second way is if the person does not shift their weight appropriately to have the swing leg clear the floor. This will cause the leg to have some additional external force that the ReWalk will sense and cause the system to return to standing mode. The stepping and walking gait pattern of the ReWalk is very similar to normal walking51. The gait pattern settings in the ReWalk can be preset in order to increase or decrease the step length, speed of the step and/or the amount of foot clearance the person will have during walking, permitting a velocity of 0.10 to 0.80 m/s.
