Central and peripheral mechanisms: a multimodal approach to understanding and restoring human motor control

Nawal Noëlle Kinany

All human actions involve motor control. Even the simplest movement requires the coordinated recruitment of many muscles, orchestrated by neuronal circuits in the brain and the spinal cord. As a consequence, lesions affecting the central nervous system, su ...

The role of the inferior parietal lobule in writer's cramp

Traian Popa

Humans have a distinguishing ability for fine motor control that is subserved by a highly evolved cortico-motor neuronal network. The acquisition of a particular motor skill involves a long series of practice movements, trial and error, adjustment and refi ...

Neuromuscular Controller Embedded in a Powered Ankle Exoskeleton: Effects on Gait, Clinical Features and Subjective Perspective of Incomplete Spinal Cord Injured Subjects

Auke Ijspeert, Florin Dzeladini

Powered exoskeletons are among the emerging technologies claiming to assist functional ambulation. The potential to adapt robotic assistance based on specific motor abilities of incomplete spinal cord injury (iSCI) subjects, is crucial to optimize Human-Ro ...

A hybrid Body-Machine Interface integrating signals from muscles and motions

Camilla Pierella

Objective.Body-Machine Interfaces (BoMIs) establish a way to operate a variety of devices, allowing their users to extend the limits of their motor abilities by exploiting the redundancy of muscles and motions that remain available after spinal cord injury ...

Designing Configurable Arm Rehabilitation Games: How Do Different Game Elements Affect User Motion Trajectories?

Pierre Dillenbourg, Friedhelm Christoph Hummel, Wafa Monia Benkaouar Johal, Maximilian Jonas Wessel, Thibault Lucien Christian Asselborn, Arzu Güneysu Özgür, Ayberk Özgür, Jennifer Kaitlyn Olsen

For successful rehabilitation of a patient after a stroke or traumatic brain injury, it is crucial that rehabilitation activities are motivating, provide feedback and have a high rate of repetitions. Advancements in recent technologies provide solutions to ...

Intraneural sensory feedback restores grip force control and motor coordination while using a prosthetic hand

Silvestro Micera, Ivo Strauss, Giacomo Valle, Francesco Maria Petrini

Objective. Tactile afferents in the human hand provide fundamental information about hand-environment interactions, which is used by the brain to adapt the motor output to the physical properties of the object being manipulated. A hand amputation disrupts ...

Wide-field imaging of cortical neuronal activity with red-shifted functional indicators during motor task execution

Silvestro Micera

Genetically encoded calcium indicators (GECIs) can be used to monitor the intracellular concentration of free calcium in populations of neurons. GECIs with long emission wavelengths are particularly attractive for deep tissue microscopy in vivo, and have t ...

Functional imaging of rostrocaudal spinal activity during upper limb motor tasks

Dimitri Nestor Alice Van De Ville, Silvestro Micera, Roberto Martuzzi, Elvira Pirondini, Nawal Noëlle Kinany

The spinal cord is the main interface between the brain and the periphery. It notably plays a central role in motor control, as spinal motoneurons activate skeletal muscles involved in voluntary movements. Yet, the spinal mechanisms underlying human moveme ...

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

Silvestro Micera

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 ...
