Data Source
This dataset is derived from a publicly available dataset generated by Camargo et al. The dataset aimed to convert the exciting dataset to a format which is used for training and evaluation of machine learning models, specifically transformer-based model, proposed by the Sharifi et al study.
The dataset comprising comprehensive data, joint kinematics along with IMU data, from 19 healthy subjects, during various activities: LW (self-selected speeds), RA, RD, SA, and SD. Each subject was equipped with four six-axis IMUs attached to the foot, shank, thigh, and torso, as well as 32 motion capture markers. The dataset offers valuable insights into lower limb biomechanics, specifically focusing on the lower limb IMU data and sagittal plane joint kinematics at the hip, knee, and ankle.
