Kinematic analysis is a powerful method for objective assessment of movement performance, and is increasingly employed as outcome measure after stroke. The number of studies investigating natural, goaloriented daily tasks is however small. Likewise, little is known how the actual movement performance measured with kinematics is related to the traditional clinical assessment scales. Furthermore,...

We present a system to automatically assess the functional performance of stroke survivors along axes defined by the Arm Motor Ability Test (AMAT). The upper body motion of seven stroke survivors was measured in a laboratory environment using a commercial motion capture device and a novel kinematic tracker of our design. Statistics generated by each individual were related to expert-determined ...

26 It is unclear how the variability of kinematic errors experienced during motor training affects 27 skill retention and motivation. We used force fields produced by a haptic robot to modulate the 28 kinematic errors of 30 healthy adults during a period of practice in a virtual simulation of golf 29 putting. On Day 1, participants became relatively skilled at putting to a near and far target b...

Cyclic motion is at the core of many sports such as running, swimming, or cycling. The study of corresponding kinematic variables is fundamental for the evaluation of training routines and the assessment of performance. Conventional kinematic analysis of human cyclic locomotion derives characteristic features from a few single cycles (e.g., average peak, average difference between peaks, as in ...

The overall goal of our research is to create a low-cost, home-based computer-based tool to monitor and assist the functional recovery of people with Upper Limb (UL) dysfunction. Our framework, implemented in the form of a Networked Virtual Driving Environment, takes advantage of manipulation of an instrumented manipulandum along prescribed movement patterns to create a sensitive and quantitati...

Dynamic knee alignment is speculated to have a stronger relationship to medial knee loading than radiographic alignment. Therefore, we aimed to determine what frontal plane knee kinematic variable correlated most strongly to the knee adduction moment. That variable was then compared with radiographic alignment as a predictor of the knee adduction moment. Therefore, 55 subjects with medial knee ...

The aim of this study was to develop new strategies based on virtual reality that can provide additional information to clinicians for the rehabilitation assessment. Virtual reality system Toyra has been used to record kinematic information of 15 patients with cervical spinal cord injury (SCI) while performing evaluation sessions using the mentioned system. Positive correlation, with a moderate...

The present contribution is motivated by recent studies on the assessment of the fluency of body movements during complex motor tasks. In particular, we focus on the estimation of the Cartesian kinematic jerk (namely, the derivative of the acceleration) of the hips’ orientation during a full threedimensional movement. The kinematic jerk index is estimated on the basis of gyroscopic signals acqu...

introduction we aimed to introduce a 6-universal-prismatic-spherical (ups) parallel mechanism for the human jaw motion and theoretically evaluate its kinematic problem. we proposed a strategy to provide a fast and accurate solution to the kinematic problem. the proposed strategy could accelerate the process of solution-finding for the direct kinematic problem by reducing the number of required ...
