Approximate analytical solutions to the double-stance dynamics of the lossy spring-loaded inverted pendulum.
Bioinspiration & biomimetics
Dec 5, 2016
This paper introduces approximate time-domain solutions to the otherwise non-integrable double-stance dynamics of the 'bipedal' spring-loaded inverted pendulum (B-SLIP) in the presence of non-negligible damping. We first introduce an auxiliary system...
Application of Machine Learning Approaches for Classifying Sitting Posture Based on Force and Acceleration Sensors.
BioMed research international
Oct 27, 2016
Occupational musculoskeletal disorders, particularly chronic low back pain (LBP), are ubiquitous due to prolonged static sitting or nonergonomic sitting positions. Therefore, the aim of this study was to develop an instrumented chair with force and a...
A new 3D center of mass control approach for FES-assisted standing: First experimental evaluation with a humanoid robot.
Medical engineering & physics
Sep 28, 2016
This paper proposes a new control framework to restore the coordination between upper (functional) and lower (paralyzed) limbs in the context of functional electrical stimulation in completely paraplegic individuals. A kinematic decoupling between th...
Development and reliability of a measure evaluating dynamic proprioception during walking with a robotized ankle-foot orthosis, and its relation to dynamic postural control.
Gait & posture
Jul 15, 2016
BACKGROUND: Proprioception is important for proper motor control. As the central nervous system modulates how sensory information is processed during movement (sensory gating), proprioceptive tests performed at rest do not correlate well with perform...
A new biarticular actuator design facilitates control of leg function in BioBiped3.
Bioinspiration & biomimetics
Jul 1, 2016
Bioinspired legged locomotion comprises different aspects, such as (i) benefiting from reduced complexity control approaches as observed in humans/animals, (ii) combining embodiment with the controllers and (iii) reflecting neural control mechanisms....
A novel robot for imposing perturbations during overground walking: mechanism, control and normative stepping responses.
Journal of neuroengineering and rehabilitation
Jun 11, 2016
BACKGROUND: The most common approach to studying dynamic balance during walking is by applying perturbations. Previous studies that investigated dynamic balance responses predominantly focused on applying perturbations in frontal plane while walking ...
Overground walking training with the i-Walker, a robotic servo-assistive device, enhances balance in patients with subacute stroke: a randomized controlled trial.
Journal of neuroengineering and rehabilitation
May 26, 2016
BACKGROUND: Patients affected by mild stroke benefit more from physiological overground walking training than walking-like training performed in place using specific devices. The aim of the study was to evaluate the effects of overground robotic walk...
Effects of reduced plantar cutaneous sensation on static postural control in individuals with and without chronic ankle instability.
Journal of science and medicine in sport
May 6, 2016
OBJECTIVES: The purpose of this study was to determine how reduced plantar cutaneous sensation influences static postural control in individuals with and without CAI.
A decision model to predict the risk of the first fall onset.
Experimental gerontology
Apr 23, 2016
BACKGROUND: Miscellaneous features from various domains are accepted to be associated with the risk of falling in the elderly. However, only few studies have focused on establishing clinical tools to predict the risk of the first fall onset. A model ...
Machine Learning Capabilities of a Simulated Cerebellum.
IEEE transactions on neural networks and learning systems
Jan 26, 2016
This paper describes the learning and control capabilities of a biologically constrained bottom-up model of the mammalian cerebellum. Results are presented from six tasks: 1) eyelid conditioning; 2) pendulum balancing; 3) proportional-integral-deriva...
