Technology-enhanced musical practice using brain–computer interfaces: a topical...
Perrotta, André; Estima, Jacinto; Cardoso, Jorge C. S.; Roque, Licínio; Pais-Vieira, Miguel; Pais-Vieira, CarlaHigh-performance musical instrument training is a demanding discipline that engages cognitive, neurological, and physical skills. Professional musicians invest substantial time and effort into mastering their repertoire and developing the muscle memory and reflexes required to perform complex works in high-stakes settings. While existing surveys have explored the use of music in therapeutic and general training...
Autonomic dysregulation mediates the association between childhood trauma and p...
Costa, Eleonora C. V.; Gonçalves, Patrícia; Martins, Fernando; Monteiro, Sílvia; Pais-Vieira, CarlaBackground: Childhood trauma is increasingly recognized as a key risk factor for autonomic nervous system (ANS) dysregulation and chronic pain. However, the mechanisms underlying this association remain insufficiently explored, particularly within integrated healthcare frameworks. Objective: This study examined whether autonomic reactivity mediates the relationship between childhood trauma and pain severity whi...
Foot-to-forearm tactile feedback for lower-limb exoskeleton control: a pilot be...
Aguiar, Mafalda; Pais-Vieira, Carla; Matos, Demétrio; Perrotta, André; Kreynin, Peter; Pais-Vieira, MiguelReal-time tactile feedback has been applied in exoskeleton-based neurorehabilitation, particularly in spinal cord injury, through Foot-to-Forearm Feedback (FFF) at ground contact. Its effects on healthy individuals across varied terrains remain less understood. This pilot study investigated seven healthy participants controlling a lower-limb exoskeleton under two conditions (with and without FFF) across five sc...
Activation of a rhythmic lower limb movement pattern during the use of a multim...
Pais-Vieira, Carla; Figueiredo, José Gabriel; Perrotta, André; Matos, Demétrio; Aguiar, Mafalda; Ramos, Júlia; Gato, Márcia; Poleri, TâniaBrain–computer interfaces (BCIs) that integrate virtual reality with tactile feedback are increasingly relevant for neurorehabilitation in spinal cord injury (SCI). In our previous case study employing a BCI-based virtual reality neurorehabilitation protocol, a patient with complete T4 SCI experienced reduced pain and emergence of non-spastic lower limb movements after 10 sessions. However, it is still unclear ...
Neurophysiological correlates of tactile width discrimination in humans
Pais-Vieira, Carla; Allahdad, Mehrab K; Perrotta, André; Peres, André; Kunicki, Carolina; Aguiar, Mafalda; Oliveira, Manuel; Pais-Vieira, MiguelIntroduction: Tactile information processing requires the integration of sensory, motor, and cognitive information. Width discrimination has been extensively studied in rodents, but not in humans. Methods: Here, we describe Electroencephalography (EEG) signals in humans performing a tactile width discrimination task. The first goal of this study was to describe changes in neural activity occurring during the di...
Sensorial feedback contribution to the sense of embodiment in brain-machine int...
Tomas, Diogo João; Pais-Vieira, Miguel; Pais-Vieira, CarlaThe sense of embodiment (SoE) is an essential element of human perception that allows individuals to control and perceive the movements of their body parts. Brain–machine interface (BMI) technology can induce SoE in real time, and adding sensory feedback through various modalities has been shown to improve BMI control and elicit SoEe. In this study, we conducted a systematic review to study BMI performance in s...

Multimodal Visual, Auditory, Thermal, and Tactile Feedback During Brain-Machine...
Pais-Vieira, Carla; Gaspar, Pedro; Matos, Demétrio; Gago, Miguel; Azevedo, Maria João; Poleri, Tânia; Perrotta, André; PaisVieira, MiguelBackground: Brain-machine interfaces (BMIs) have the potential to replace and expand body functions, but also to induce neuroplasticity. In BMIs that include virtual reality and tactile feedback, it is thought that the underlying mechanism may be partially dependent on immersiveness (i.e., how “realistic” the environment is). It is not known however, if continuously increasing the number of simulation modalitie...
Monetary Reward Effects in Discrimination and Neurophysiological Activity Durin...
Pais-Vieira, Carla; Matos, Demétrio; Perrotta, André; Pais-Vieira, MiguelThe development of devices capable of delivering tactile and thermal feed-back have the potential to improve brain-machine interfaces for neuroreha-bilitation protocols. Monetary rewards are known to improve some types of passive tactile processing. The aim of this study was to describe the perfor-mance and neural activity of subjects receiving tactile stimuli through a tac-tile stimulation sleeve in the presen...
Serious games for physical rehabilitation: aesthetic discrepancies between cust...
Vieira, Catarina; Perrotta, André; Pais-Vieira, CarlaSerious games are videogames that are used with purposes that go beyond the mere entertainment of the player. Among their many applications, healthcare is one of the most prominent ones, as serious games can have a wide range of uses within this field, namely physical rehabilitation of patients. For this purpose, both custom-made serious games and commercial entertainment titles, such as those for Nintendo Wii,...
