Biomechanical analysis and modelling of sit to stand task: a literature review

Rising from the seated position is an activity carried out by most people many times daily. Physical disabilities ultimately express themselves as changes in the biomechanics of physical-task performance. Quantitative measures are sorely needed because they can serve as indicators of subtle changes in one´s functioning over time. The purpose of this paper is to present an overview of the literature related to the biomechanical aspect of sit-to-stand transfer in the able-bodied and the elderly population, and to highlight the determinant factors that affect the sit-to-stand transition
