Effects of repeated waist-pull perturbations on gait stability in subjects with cerebellar ataxia

Background: Damage to the cerebellum can affect neural structures involved in locomotion, causing gait and balance disorders. However, the integrity of cerebellum does not seem to be critical in managing sudden and unexpected environmental changes such as ...

An Event-Driven Closed-Loop System for Real-Time FES Control

Silvestro Micera, Andrea Crema, Danilo Demarchi

Active functional rehabilitation procedures, exoskeleton application and prosthesis employment are essential tools for the society life reinstatement of subjects affected by neuromuscular disorders or victims of serious physical accident. In this paper we ...

Effectiveness of a Robot-Mediated Strategy While Counteracting Multidirectional Slippages

Silvestro Micera

This study investigates the effectiveness of a robot-mediated strategy aimed at promoting balance recovery after multidirectional slippages. Six older adults were asked to manage anteroposterior and mediolateral slippages while donning an active pelvis ort ...

From standing balance to walking: A single control structure for a continuum of gaits

Auke Ijspeert, Salman Faraji, Seyed Hamed Razavi

This article presents a control algorithm framework with which a bipedal robot can perform a variety of gaits by only modifying a small set of control parameters. The controller drives a number of variables, called non-emergent variables, to their desired ...

Modulation of vection latencies in the full-body illusion

Olaf Blanke, Bruno Herbelin, Alessandro Nesti, Giulio Rognini

Current neuroscientific models of bodily self-consciousness (BSC) argue that inaccurate integration of sensory signals leads to altered states of BSC. Indeed, using virtual reality technology, observers viewing a fake or virtual body while being exposed to ...

Preliminary Study: Effects of Visual Distortion on Standing Balance Motion Amplitude and Visual Dependency on an Unstable Surface

Olaf Blanke, Hannes Bleuler, Mohamed Bouri, Jemina Fasola

Visual feedback is a common method to enhance motor learning and is widely used in rehabilitation institutes. Although balance training with visual feedback has shown positive results, the most effective way to provide the feedback is still open to researc ...

Differential effects of vestibular processing on orienting exogenous and endogenous covert visual attention

Olaf Blanke, Andrea Serino, Mariia Kaliuzhna, Steve Michel Berger

Recent research highlights the overwhelming role of vestibular information for higher order cognition. Central to body perception, vestibular cues provide information about self-location in space, self-motion versus object motion, and modulate the percepti ...

An ecologically-controlled exoskeleton can improve balance recovery after slippage

Silvestro Micera

The evolution to bipedalism forced humans to develop suitable strategies for dynamically controlling their balance, ensuring stability, and preventing falling. The natural aging process and traumatic events such as lower-limb loss can alter the human abili ...

Multisensory interactions in peripersonal space and their contributions to bodily self-consciousness

Petr Grivaz

What is the relevance of the body and body-transformed sensory information for subjective experience? In the last two decades, paradigms from cognitive neuroscience have demonstrated that the subjective sensations of possessing a body (body ownership, BO), ...

Modelling Neuromuscular Function of SCI Patients in Balancing

Arash Arami, Etienne Burdet

A novel neuromechanical model for investigating patient-specific lower limb movement dynamics after spinal cord injury (SCI) is presented. The model is designed in joint space and takes into account muscle neuromechanics. Application of the model is demons ...
