Successful ambulation at home and in the community is the main goal of gait training after incomplete spinal cord injury. Many different treatment approaches have been recommended to achieve this goal. One established intervention to achieve that in a clinical setting is body weight supported (BWS) treadmill training. However, recent studies have suggested that the most optimal gait training should be conducted overground with appropriate support conditions to enable a physiological gait pattern. The training has to be challenging and patients must participate as active as possible.
In addition becoming a functional walker in real world involves a variety of walking skills like walking on uneven surfaces, walking up and down slopes, climbing stairs and avoid obstacles. It has been shown in humans as well as in animals that greater improvements are achieved in walking function if the training is task specific. Thus a constrained task like BWS treadmill training may not be the optimal training intervention to become a functional community walker.
Even greater improvements can be expected if patients feel safe during the overground walking and train at their individual limits. With FLOAT there is now the possibility to conduct a task specific BWS overground gait training in a safe environment. The robotic device allows patients to perform different walking tasks like walking overground, avoiding obstacles, walking on uneven and sloped surfaces, climbing stairs, walking in narrow spaces. A virtual reality setup was integrated into the system that even can simulate specific walking tasks like target oriented walking or walking in crowded environment. Based on the promising results seen in preclinical and clinical research, the investigators assume that unrestricted transparent BWS overground training that allows task specific training of real world walking tasks will induce greater improvements than conventional BWS treadmill training.
The investigators will compare the effect of an intensive 4 weeks unrestricted BWS overground gait training to 4 weeks of intensive BWS treadmill training. Not only functional outcome like walking speed or capacity will be assessed but also detailed kinematics that will help to identify the mechanisms of the underlying improvements in walking function.

|Official Title:||Body Weight Supported Overground Gait Training to Promote Recovery of Walking Function in Chronic Spinal Cord Injury: a Randomized Clinical Trial|

|Estimated Study Completion Date :||May 31, 2021|
|Active Comparator: SCI-patients receiving overground training||
Other: BWS overground training
BWS will be provided with the goal to impose the maximal lower extremity weight bearing load without excessive knee flexion during stance phase and/ or toe dragging during the swing phase. The walking tasks will be roughly divided into different domains like skilled walking, balance, dual tasking, walking speed, walking endurance.
|Active Comparator: SCI-patients receiving treadmill training||
Other: BWS treadmill training
Training will be conducted on a standard treadmill with an overhead BWS system that can provide active BWS. Participants are allowed to hold the rails but weight bearing is not allowed. BWS will be provided with the goal to impose the maximal lower extremity weight bearing load without excessive knee flexion during stance phase and/ or toe dragging during the swing phase. Main walking tasks will be endurance (walking long distances at preferred speed) and speed (walking at maximal possible speed).
- Change of walking ability (6mWT) [ Time Frame: Prior, in the middle, at the end of and 1 month after the training intervention ]
