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 S.; 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 Matos; 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,...
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...
Translation and cross-cultural adaptation of quality of life scale in patients ...
Silva-Neves, Vasco; Caramelo, Ana; Alves, Paulo; Pais-Vieira, Carla; Minton, Alexandra Palmer; Rodríguez-Leboeuf, Ana María; Pais-Vieira, Miguel(1) Background: Onychomycosis (OM) is a fungal nail infection, considered a risk factor for diabetic foot ulcers. It is associated with changes in quality of life, in terms of pain, self-confidence and self-esteem. The aim was to translate and adapt the OM quality of life questionnaire “OnyCOE-t™–Quality Of Life Questionnaire Onychomycosis (Nail Fungal Condition)”. (2) Methods: This study followed the guideline...
