Walking adaptability for targeted fall-risk assessments

...taking steps towards a better identification of (future) fallers

Walking adaptability is defined as the ability to modify walking to meet behavioural task goals and  demands of the environment. Walking-related falls often occur due to trips, slips or misplaced steps,  suggesting that people have problems adapting walking. Walking adaptability therefore seems to be  related to fall risk and appears to be an important component of safe walking. 

The Interactive Walkway is an 8- or 10-meter walkway instrumented with an integrated multi-Kinect  v2 set-up for markerless registration of 3D full-body kinematics during walking. The Interactive  Walkway is equipped with a projector to augment the entire walkway with (gait-dependent) visual  context, such as obstacles, sudden-stop-and-start cues and stepping targets. Using the real-time  processed integrated Kinect data, obstacles can suddenly appear at the position one would step next,  demanding a step adjustment under time pressure demands. The so-elicited gait-environment interactions allow for assessing various walking-adaptability aspects (e.g., the ability to avoid  obstacles, suddenly stop or start, perform accurate goal-directed steps) in a safe manner.
