Effects of Hemispheric Stroke Localization on the Reorganization of Arm Movements within Different Mechanical Environments

This study investigated how stroke's hemispheric localization affects motor performance, spinal maps and muscle synergies while performing planar reaching with and without assistive or resistive forces. A lesion of the right hemisphere affected performance ...

Stroke impairs the control of isometric forces and muscle activations in the ipsilesional arm

Martina Coscia

Stroke often impairs the control of the contralesional arm, thus most survivors rely on the ipsilesional arm to perform daily living activities that require an efficient control of movements and forces. Whereas the ipsilesional arm is often called 'unaffec ...

A multimodal approach to capture post-stroke temporal dynamics of recovery

Dimitri Nestor Alice Van De Ville, Silvestro Micera, Jenifer Cléa Miehlbradt, Nawal Noëlle Kinany, Elvira Pirondini, Martina Coscia, Christian Giang, Camilla Pierella

Objective.Several training programs have been developed in the past to restore motor functions after stroke. Their efficacy strongly relies on the possibility to assess individual levels of impairment and recovery rate. However, commonly used clinical scal ...

Motor improvement estimation and task adaptation for personalized robot-aided therapy: a feasibility study

Silvestro Micera, Jenifer Cléa Miehlbradt, Nawal Noëlle Kinany, Elvira Pirondini, Camilla Pierella, Martina Coscia, Christian Giang

Background In the past years, robotic systems have become increasingly popular in upper limb rehabilitation. Nevertheless, clinical studies have so far not been able to confirm superior efficacy of robotic therapy over conventional methods. The personaliza ...

Muscle activities in similar arms performing identical tasks reveal the neural basis of muscle synergies

Martina Coscia

Are the muscle synergies extracted from multiple electromyographic signals an expression of neural information processing, or rather a by-product of mechanical and task constraints? To address this question, we asked 41 right-handed adults to perform a var ...

Neurotechnology-aided interventions for upper limb motor rehabilitation in severe chronic stroke

José del Rocio Millán Ruiz, Silvestro Micera, Friedhelm Christoph Hummel, Maximilian Jonas Wessel, Martina Coscia, John Donoghue

Upper limb motor deficits in severe stroke survivors often remain unresolved over extended time periods. Novel neurotechnologies have the potential to significantly support upper limb motor restoration in severely impaired stroke individuals. Here, we revi ...

Teleoperation with a wearable sensor system

David Atienza Alonso, Dario Floreano, Silvestro Micera, Stefano Mintchev, Jenifer Cléa Miehlbradt, Fiorenzo Artoni, Martina Coscia, Fabio Isidoro Tiberio Dell'Agnola, Alexandre Thierry Cherpillod

A method for remotely controlling an operated unmanned object, comprises defining of a set of control movements of an operator; selecting of minimal necessary signals to reliably acquire the operator's control movements; defining of a mapping of the contro ...

Evaluating upper limb impairments in multiple sclerosis by exposure to different mechanical environments

Martina Coscia

Multiple sclerosis is a chronic, autoimmune and neurodegenerative disease affecting multiple functional systems and resulting in motor impairments associated with muscle weakness and lack of movement coordination. We quantified upper limb motor deficits wi ...
