In this paper, batting motions between expert baseball players and beginner players are quantitatively compared and discussed, based on Kinetic and Kinematic analysis methods by using bio-instrumentation systems. We measure batting speed, center-of-gravity movements, a rotating angle of body trunk axis and a ground reaction force as kinematic data, and muscles power of the lower limb as kinetics data...
People with physical impairments often have asymmetric gait. To evaluate if their overall symmetry is improving during intervention, there needs to be a simple metric that can help classify gait patterns that includes multiple measures of gait asymmetry. The Combined Gait Asymmetry Metric presented here is based on the Mahalanobis distance of multiple step parameters. We tested able-bodied subjects...
This paper adopts guidance and control framework to address the problem of path following for an under-actuated autonomous underwater vehicle (AUV) moving in three dimensional (3D) space. First, based on the error dynamics in the moving path frame, the desired pitch angle and yaw angle are designed in kinematics by 3D Line-of-Sight (LOS) guidance law. Subsequently, the desired pitch and yaw angular...
β oscillations in local field potentials, electro-corticography (ECoG), and electroencephalograms (EEG) are ubiquitous in the motor cortex of monkeys and humans. However due to their lack of contributions, compared to other frequency ranges, to decode effector kinematics especially in ECoG signals, spatiotemporal dynamics of ECoG β oscillations has not been examined despite the larger areas that ECoG...
In this study the potential of decision tree (DT)specifically Classification and Regression Tree (CART) isinvestigated in classifying Parkinsononian gait pattern due to motor impairment. Firstly, gait features extracted duringwalking experiments namely basic spatiotemporal parameters,kinetic parameters and kinematic parameters by twelve PDpatients and twenty control group are acquired as database...
The status of motor function in stroke survivors and the effect of any therapeutic intervention are generally measured by physiotherapists using clinical assessment scales that probe specific aspects of a subject's motor behavior. Although they are widely accepted, these measurement tools are limited by interrater and intrarater reliability and are time-consuming to apply. This paper analyzes the...
LifeMOD is a set of commonly used simulation software. It might generate the biomechanics data because of the parameter hypothesis and the various parameter hypothesis would possibly have offset or wrong result. Therefore, the accuracy of these parameters are important. The objectives of this research was to compare experimental data with simulation results with various parameters. In the future,...
The injuries in the lower limbs are common at the sports, and one of the most common injuries is ankle sprain. Kinesio taping is one of the useful treatments of ankle sprain. The objective of this study is to investigate the biomechanical effects of ankle Kinesio taping on ground impacts during the landing of vertical jump, and the effect of ankle Kinesio taping on vertical jump in functional instability...
