The effects of learning with various noise on Gait Kinematics in 3-to-5-year-old children: a randomized controlled trial

BMC Sports Science, Medicine and Rehabilitation, 2022
Background Lack of the neuromuscular control during locomotion in the knee joint leads to an increased risk of anterior cruciate ligament (ACL) injury in children. Hence, we aimed to explore the effects of a repetitive, model-oriented, and self-organized

Self-Organization of Lower Limb Motion in Human Locomotion

Journal of Robotics and Mechatronics, 1996
This project was undertaken to demonstrate the modal bifurcation displayed in human locomotion and the nature of motional self-organization found in the lower limb joints via the continuously measured walking and running of subjects on a treadmill for five minutes.

Incremental embodied chaotic exploration of self-organized motor behaviors with proprioceptor adaptation [PDF]

, 2015
This paper presents a general and fully dynamic embodied artificial neural system, which incrementally explores and learns motor behaviors through an integrated combination of chaotic search and reflex learning.

Self-rated health determinants in post-stroke individuals

Journal of Rehabilitation Medicine, 2020
Objective: To investigate whether variables of function and disability, which have potential to be modified by rehabilitation, are determinants of self-rated health in post-stroke individuals in the chronic phase.

Tissue self-organization based on collective cell migration by contact activation of locomotion and chemotaxis [PDF]

Proceedings of the National Academy of Sciences, 2018
AbstractDespite their central role in multicellular organization, navigation rules that dictate cell rearrangement remain much to be elucidated. Contact between neighboring cells and diffusive attractant molecules are two of the major determinants of tissue-level patterning, however in most cases, molecular and developmental complexity hinders one from

Chaotic exploration and learning of locomotion behaviours [PDF]

, 2012
We present a general and fully dynamic neural system, which exploits intrinsic chaotic dynamics, for the real-time goal-directed exploration and learning of the possible locomotion patterns of an articulated robot of an arbitrary morphology in an unknown

Mimicking Sub-Structures Self-Organization in Microtubules

Biomimetics, 2019
Microtubules (MTs) are highly dynamic polymers distributed in the cytoplasm of a biological cell. Alpha and beta globular proteins constituting the heterodimer building blocks combine to form these tubules through polymerization, controlled by the ...

A Quadruped Robot Exhibiting Spontaneous Gait Transitions from Walking to Trotting to Galloping

Scientific Reports, 2017
The manner in which quadrupeds change their locomotive patterns—walking, trotting, and galloping—with changing speed is poorly understood. In this paper, we provide evidence for interlimb coordination during gait transitions using a quadruped robot for ...

Kinematic Description of Self-Organized Leg Motion Transition in Human Locomotion Learning

Journal of Robotics and Mechatronics, 1998
Leg motion learning while walking backward with eyes closed on a treadmill was studied to gain information on self-organization in locomotion learning. Eight adults walked on a treadmill at a belt speed of 50 m/min for five minutes,, four times. The angles of the hip, knee, and ankle joints were calculated to describe lower limb motion transition with ...

A Game-theoretic Formulation of the Homogeneous Self-Reconfiguration Problem [PDF]

, 2015
In this paper we formulate the homogeneous two- and three-dimensional self-reconfiguration problem over discrete grids as a constrained potential game. We develop a game-theoretic learning algorithm based on the Metropolis-Hastings algorithm that solves ...
