Land and Underwater Gait Analysis Using Wearable IMU

Walking underwater reduces joint impacts, enhances stability and lowers the net body weight of patient during rehabilitation. It is a recent rehabilitation method few suitable methods exist to study gait kinematics. We propose an inertial measurement (IMU) system analogous those used in land-based investigate The objective this was test validate proposed two human trials by evaluating knee angle gait. In first trial, three-way performance analysis carried out between IMU, optoelectronic motion-capture systems traditional setting on land. second IMU compared with camera-based both inside outside water environment, using same subjects phases trial. This allows for evaluation walking air as well cross-comparison IMU-based estimates before after Gaussian Process Regression. major finding work that wearable provides reliable repeatable measurements gait, underwater.
