Controllo dell'atto di prensione: coinvolgimento dell'area V6A nell'orientamento del polso
Prehension in an act of coordinated reaching and grasping. The reaching component is concerned with bringing the hand to object to be grasped (transport phase); the grasping component refers to the shaping of the hand according to the object features (grasping phase) (Jeannerod, 1981). Reaching and …

Quantifying prehension in persons with stroke post rehabilitation
This study describes the analysis of reaching and grasping abilities of the hemiparetic arm and hand of patients post stroke after a series of interactive virtual reality (VR) simulated training sessions and conventional physical therapy of similar intensity. Six subjects participated in VR …

The role of peripheral visual cues in planning and controlling movement :|ban investigation of which cues provided by different parts of the visual field influence the execution of movement and how they work to control upper and lower limb motion.
… position of the body within the environment and are continuously updated while moving (online), and visual exteroceptive when describing static features of the environment which are typically elaborated offline (feedforward). However peripheral visual cues involved in the control of movement …

Effects of Object Function on Visual Search in Real-World Scenes
… that exists naturally between an object and the action possibilities inherent within it. Object affordances result from complex visuomotor interactions and are reflected in many processes, including reaching and grasping behaviours, distance judgments, and object identification. With the …

Histological and Functional Characterization of Cervical Spinal Cord Injury After Graded Contusion
… cord injuries (SCIs) are cervical contusions and result in deficits for both locomotion and reaching and grasping functions. Previous studies have characterized histological and functional deficits in locomotion using primarily thoracic contusions, but most patients have cervical injuries. …

Neural representations of movement planning within the human prehension system
… Whereas we begin to have a better understanding of the neural mechanisms underlying the execution of object-directed movements, less is known about how exactly our brain makes the plan for action. Previous studies examining movement planning suggested that neuronal populations in …

Wearable robotics for rehabilitation
… discussion on their use as assistive devices and as products or systems that aid in rehabilitation of disabled people. I will technically investigate the current state-of-art wearable robotic devices in relation to physical rehabilitation and use of robots as assistive technology. Assistive …

Machine-Learning-Based Approach to Decoding Physiological and Neural Signals
… powerful tools in decoding physiological and neural signals. The aim of this dissertation is to develop computational tools, and especially machine learning techniques, to identify the most effective methods for feature extraction and classification of these signals. This is particularly …

Development of a wireless ditributed three channel stimulator used for automatic triggering of stimulation to enable co-ordinated task execution of stroke patients
Each year, hundreds of thousands of people are affected by a neurological related disease or injury causing some of them partial or complete dysfunction of one or more limbs. Functional Electrical Stimulation (FES) techniques have shown a significant improvement in mobility and function for many of …

Age-related differences in visuomotor integration as measured by object affordance effects - a combined behavioural and neurophysiological investigation
Visuomotor behaviour – from handling simple objects to operating complex devices – is of fundamental importance in our everyday lives, yet there is relatively little evidence as to how healthy ageing affects these processes. A central role is played by the human capacity for reaching and grasping. …

Inhibitory effect of subthreshold transcranial magnetic stimulation on the stretch-evoked long latency response of forearm muscles
… in locomotion, maintenance of posture, reaching, and grasping, which has considerable importance for recovery from corticospinal lesions such as stroke. There is currently a debate on whether increased reticulospinal function is necessary for recovery of motor function after severe …

Cognitive-motor interaction in health and disability
… the completion of movements such as locomotion, reaching and grasping. Often these movements are performed in complex and distracting environments with specific goals in mind. Traditionally, habitual motor tasks such as walking have been viewed as unrelated to the cognitive domain; however, there …
