Edições ISMAI.978-989-53655-5-5http://hdl.handle.net/10400.15/4657The Recurrence Quantification Analysis (RQA), applied to fine motor skills in children, may be used to observe the behavior of the state of the child, which allows to study and understand the process that he/she is going through. This study aims to analyze the evolution of the fine motor skills between 6 and 9 years old. An inertial sensor was used to collect 3D data during FTT from 60 primary school children and was calculated Recurrence (REC) and Determinism (DET) of the collected time series. Results shows a decrease of REC and DET along ages and higher values in non-preferred hand. RQA shows great sensibility to evaluate fine motor skills and its visible an onset of differentiation between hands through these ages.engrecurrence quantification analysisFTTchildrenfine motor skillsbook part
