The current method used to estimate the balance a person has during the performance of Activities of Daily Life (ADLs) is through the application of standardized scales used by occupational therapists to evaluate a person's motor skills and performance quality during those activities, such as the Assessment of Motor and Process Skills scale (AMPS). In this paper, we propose a method to automate the evaluation of a person's balance during the stage of quiet standing still while a person is completing an ADL. Our proposal is aimed to first estimate the projection of the person's center of mass (CoM) from the 3D position of the body joints by applying theoretical and deep learning approaches. Then, we aim to predict a clinically validated objective balance score from previous estimations of the CoM and the Center of Pressure (CoP), using different neural network models. While there are other proposals in the literature, the lack of publicly available datasets makes it difficult to do an extensive comparison, so we compare our proposal with state-of-the-art results in two publicly available datasets, improving their results.
