Comparison of linear accelerations from three
نویسندگان
چکیده
Given the increased use of accelerometers in movement analysis, validation of such inertial sensors against conventional 3D camera systems and performance comparisons of different sensors have become important topics in biomechanics. This paper evaluates and compares linear acceleration trajectories obtained from two different accelerometers and derived from Vicon position data for an upper limb “reach & grasp” task. Overall, good correspondence between the three measurement systems was obtained. Sources of error are discussed. Keywords-accelerometry; accelerations; inertial measurement; validation; movement analysis; camera systems; error; accuracy

Developmental expression of tyrosine kinase b in rat vestibular nuclear neurons responding to horizontal and vertical linear accelerations
Brain-derived neurotrophic factor (BDNF) is known to be crucial for the development of peripheral vestibular neurons. However, the maturation profile of the BDNF signal transducing receptor, tyrosine kinase B (TrkB) in functionally activated otolith-related vestibular nuclear neurons of postnatal rats remains unexplored. In the present study, conscious Sprague-Dawley rats (P4 to adult) were sub...
متن کاملPrediction of Body Center of Mass Acceleration From Trunk and Lower Limb Joints Accelerations During Quiet Standing
Purpose: Predicting body Center of Mass (COM) acceleration is carried out with more accuracy based on the acceleration of three joints of lower limb compared to only accounting joints of hip and ankle. Given that trunk movement during quite standing is noticeable, calculating trunk acceleration in model might increase prediction accuracy of COM acceleration. Moreover, in previous research studi...
متن کاملA biomechanical modeling of an automotive passenger body to investigate the vertical vibration in various road profiles using transmissibility analysis
In the current paper, a biomechanical model of human body with unique structure is developed for evaluating the biodynamic responses, the vibration transmissibility and the transmitted accelerations to vertical vibration for the seated position with ignoring backrest support. In this regard, the 6-DoF Lumped-parameter model with six concentrated masses which are connected with linear springs an...

متن کاملTransmitted vibrations to the wrist and arm of a chainsaw operator: The effect of wood cutting process
Introduction: Due to the non-developed mechanization situation, chainsaw is a widely used tool in Iranian forests. This tool can trigger unwelcome disorders (e.g., white finger syndrome) due to the transmitted vibrations from its handle to the body members. Characterizing these vibrations can result in minimizing the intensity of these disorders. This study aims to investigate the effect of dif...
