Fig. 2From: Design, development, and evaluation of a local sensor-based gait phase recognition system using a logistic model decision tree for orthosis-controlAverage knee angle (degrees) and standard deviation from a single participant for each surface condition (rows) and walking speed (columns), showing classified gait phases: Loading Response (blue), Push-Off (red), Swing (cyan), Terminal Swing (teal) for the training set. Shaded areas behind the signatures show true classes along the stride and vertical lines represent gait eventsBack to article page
