Reliability and differentiation capability of dynamic and static kinematic measurements of rearfoot eversion in patellofemoral pain
(Elsevier B. V., 2015)
Excessive rearfoot eversion is thought to be a risk factor for patellofemoral pain development, due to the kinesiological relationship with ascendant adaptations. Individuals with patellofemoral pain are often diagnosed ...
Optimal Trajectory and Solution of the Inverse Kinematics of a Robotic Manipulator by Genetic Algorithms
(Springer, 2011-01-01)
This paper presents the generation of optimal trajectories by genetic algorithms (GA) for a planar robotic manipulator. The implemented GA considers a multi-objective function that minimizes the end-effector positioning ...
Reduced knee flexion is a possible cause of increased loading rates in individuals with patellofemoral pain
(Elsevier B. V., 2015)
Stair ascent is an activity that exacerbates symptoms of individuals with patellofemoral pain. The discomfort associated with this activity usually results in gait modification such as reduced knee flexion in an attempt ...
Joint forces and torques when walking in shallow water
(ELSEVIER SCI LTD, 2011)
This study reports for the first time an estimation of the internal net joint forces and torques on adults` lower limbs and pelvis when walking in shallow water, taking into account the drag forces generated by the movement ...
The effect of muscle fatigue on the last stride before stepping down a curb
(2013-04-01)
The stride before landing may be important during stepping down. The aim of this study was to analyze variability of the kinematics and muscle activity in the final stride before stepping down a curb, with and without ankle ...

Kinematic Analysis and Performance of a Planar 3RRR Parallel Robot with Kinematic Redundancy using Screw Theory
(Institute of Electrical and Electronics Engineers Inc., 2018)
In this paper, a complete kinematic analysis of a planar 3-RRR parallel robot is presented. The position through the direct and inverse kinematics, velocities, jacobians and accelerations were developed using Screw Theory. ...
Redes neurais como alternativas ao Jacobiano na solução iterativa da cinemática inversa
(Universidade Federal de Santa MariaBrasilCiência da ComputaçãoUFSMPrograma de Pós-Graduação em Ciência da ComputaçãoCentro de Tecnologia, 2019-03-25)
The usage of robots has become a normal practice today thanks to large technological advances
in recent decades. The planning of robots’ movements in the environment is one of
the most important fundaments in the study ...
