Human Gait Analysis and Prediction Using the Levenberg-Marquardt Method. [PDF]
J Healthc Eng, 2021 A high-accuracy gait data prediction model can be used to design prosthesis and orthosis for people having amputations or ailments of the lower limb. The objective of this study is to observe the gait data of different subjects and design a neural network to predict future gait angles for fixed speeds. The data were recorded via a Biometrics goniometer,
