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...
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...

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...
Embodiment comfort levels during motor imagery training combined with immersive...
Pais-Vieira, Carla; Gaspar, Pedro; Matos, Demétrio; Alves, Leonor Palminha; Cruz, Bárbara Moreira da; Azevedo, Maria João; Gago, Miguel; Poleri, TâniaBrain–machine interfaces combining visual, auditory, and tactile feedback have been previously used to generate embodiment experiences during spinal cord injury (SCI) rehabilitation. It is not known if adding temperature to these modalities can result in discomfort with embodiment experiences. Here, comfort levels with the embodiment experiences were investigated in an intervention that required a chronic pain ...
Quality of life and therapeutic regimen management in onychomycosis patients an...
Silva-Neves, Vasco; Hugo, Vitor; Alves, Paulo; Amado, João Costa; Pais-Vieira, Carla; Sousa, Fátima; Cerqueira, Fátima; Pinto, EugéniaOnychomycosis or tinea unguium (EE12.1) and Onychomycosis due to non-dermatophyte moulds (1F2D.5) (OM) is a fungal infection of the nail plates with a high prevalence that often afects vulnerable people with co-existing health problems. Gold standard pharmacological treatments for onychomycosis have been associated with low success rates and increasing antifungal resistance, suggesting that treatment outcome is...
Does symptom recognition improve self-care in patients with heart failure? A pi...
Sousa, Joana Pereira; Neves, Hugo; Pais-Vieira, MiguelPatients with heart failure have difficulty in self-care management, as daily monitoring and recognition of symptoms do not readily trigger an action to avoid hospital admissions. The purpose of this study was to understand the impact of a nurse-led complex intervention on symptom recognition and fluid restriction. A latent growth model was designed to estimate the longitudinal effect of a nursing-led complex i...
