Neurophysiological underpinnings of an intensive protocol for upper limb motor recovery in subacute and chronic stroke patients
Silvestro Micera, Matteo Vissani, Michael Lassi
ABS T R A C T BACKGROUND: Upper limb (UL) motor impairment following stroke is a leading cause of functional limitations in activities of daily living. Robot-assisted therapy supports rehabilitation, but how its efficacy and the underlying neural mechanism ...
Turin2023Neural Joint Space Implicit Signed Distance Functions for Reactive Robot Manipulator Control
Aude Billard, Mikhail Koptev, Nadia Barbara Figueroa Fernandez
In this paper, we present an approach for learning a neural implicit signed distance function expressed in joint space coordinates, that efficiently computes distance-to-collisions for arbitrary robotic manipulator configurations. Computing such distances ...
2022Postural transitions detection and characterization in healthy and patient populations using a single waist sensor
Kamiar Aminian, Farzin Dadashi, Benoît Mariani, Arash Atrsaei
Background: Sit-to-stand and stand-to-sit transitions are frequent daily functional tasks indicative of muscle power and balance performance. Monitoring these postural transitions with inertial sensors provides an objective tool to assess mobility in both ...
2020Towards a geometry independent traction-separation and angle relation due to large scale bridging in DCB configuration
Traction-separation relations due to large scale bridging in composites are very important in modeling their fracture response. Several works demonstrated that such relations are dependent upon the specimen's stiffness and loading conditions. Experimental ...
ELSEVIER SCI LTD2020SCALAR: Simultaneous Calibration of 2-D Laser and Robot Kinematic Parameters Using Planarity and Distance Constraints
In this paper, we propose SCALAR, a calibration method to simultaneously calibrate the kinematic parameters of a 6-DoF robot and the extrinsic parameters of a 2-D laser range finder (LRF) attached to the robot's flange. The calibration setup requires only ...
2019Patient Motion Using a Computerized Leg Brace in Everyday Locomotion Tasks
Exoskeletal systems are becoming a rehabilitation standard of care for persons with lower limb paralysis. As muscular dysfunctions affect a heterogeneous patient group, each individual develops their own strategy to negotiate everyday locomotion challenges ...
2019Reading from the Black Box: What Sensors Tell Us about Resting and Recovery after Real-World Falls
Lying on the floor for a long time after falls, regardless of whether an injury results, remains an unsolved health care problem. In order to develop efficient and acceptable fall detection and reaction approaches, it is relevant to improve the understandi ...
2018Priority coordination of fiber positioners in multi-objects spectrographs
Denis Gillet, Jean-Paul Richard Kneib, Mohamed Bouri, Laleh Makarem
Projects such as "The Dark Energy Spectroscopic Instrument" (DESI) [1] or "The Multi Object Optical and Near-infrared Spectrograph" (MOONS) [5] are developing spectrographs, composed of more than thousand of optical fibers in a confined hexagonal focal pla ...
SPIE-INT SOC OPTICAL ENGINEERING2018Higher-order continuation method for the rigid-body kinematic design of compliant mechanisms
Simon Nessim Henein, Lennart Rubbert
Compliant mechanisms are of great interest in precision engineering. In this paper we propose a higher order continuation method to help their rigid-body kinematic design. The method helps to investigate the choice of a mechanism configuration through the ...
Elsevier2017Calculation of the General Number of Imposed Constraints of Kinematic Chains
The study provides derivation and application of novel formula for the calculation of general imposed constraints for kinematic chains (including mechanisms and zero-degrees-of-freedom Assur groups) depending on the types of kinematic pairs and numbers of ...
