Optimizing Growth Conditions and Biochemical Properties of Chondracanthus acicu...
Mouga, Teresa; Sousa, Andreia; Freitas, Marta; Afonso, CléliaThis study aimed to evaluate the laboratory cultivation of Chondracanthus acicu laris, focusing on key environmental parameters such as nutrient levels and light exposure. The results provide insights into the optimal growth conditions and biochemical com position of C. acicularis, which are crucial for its sustainable exploitation in industrial applications. Significant differences in the relative growth rate ...
A comprehensive understanding of postural tone biomechanics: intrinsic stiffnes...
Pinho, Liliana; Freitas, Marta; Pinho, Francisco; Silva, Sandra; Figueira, Vânia; Ribeiro, Edgar; Sousa, Andreia S. P.; Sousa, Filipa; Silva, AugustaTo analyse the relationship between traditional stiffness and muscle antagonist coactivation in both stroke and healthy participants, using linear and nonlinear measures of coactivation and COP during standing, stand-to-sit, and gait initiation. Participants were evaluated through a cross-sectional design. Electromyography, isokinetic dynamometer, and force plate were used to calculate coactivation, intrinsic a...
Replacing the Gallium Oxide Shell with Conductive Ag: Toward a Printable and Re...
Hajalilou, Abdollah; Parvini, Elahe; Morgado, Tiago A.; Lopes, Pedro Alhais; Jorge, M. Estrela Melo; Freitas, Marta; Tavakoli, MahmoudLiquid metal (LM)-based composites hold promise for soft electronics due to their high conductivity and fluidic nature. However, the presence of α-Ga2O3 and GaOOH layers around LM droplets impairs conductivity and performance. We tackle this issue by replacing the oxide layer with conductive silver (Ag) using an ultrasonic-assisted galvanic replacement reaction. The Ag-coated nanoparticles form aggregated, poro...
Wearables for monitoring and postural feedback in the work context: A scoping r...
Figueira, Vânia; Silva, Sandra; Costa, Inês; Campos, Bruna; Salgado, João; Pinho, Liliana; Freitas, Marta; Carvalho, Paulo; Marques, JoãoWearables offer a promising solution for simultaneous posture monitoring and/or corrective feedback. The main objective was to identify, synthesise, and characterise the wearables used in the workplace to monitor and postural feedback to workers. The PRISMA-ScR guidelines were followed. Studies were included between 1 January 2000 and 22 March 2023 in Spanish, French, English, and Portuguese without geographica...
Clinical measures for tone assessment in adults with central nervous system dis...
Pinho, Liliana; Silva, Sandra; Freitas, Marta; Figueira, Vânia; Pinho, Francisco; Cunha, Christine; Sousa, Andreia S. P.; Sousa, Filipa; Silva, AugustaAssessment of muscle tone in a clinical setting is important for the physiotherapist to better analyse and establish appropriate treatments for CNS disorders. This study aims to review and summarise how to assess changes in tone in the context of adult rehabilitation. Secondarily, this study aimed to identify the central nervous system disorders, the respective variable/concept under study, and the testing proc...
European Portuguese version of the Mini-BESTest: a cross-cultural adaptation an...
Freitas, Marta; Pinho, Francisco; Cruz-Martins, Natália; Pinho, Liliana; Silva, Sandra; Figueira, Vânia; Vilas-Boas, João Paulo; Silva, AugustaThis study aimed to translate and cross-culturally adapt the Mini-BESTest into European Portuguese and to evaluate its psychometric properties in individuals with sensorimotor impairments. A cross-sectional cross-cultural adaptation and validation study was conducted according to the COSMIN guidelines and the STROBE statement. The study included 100 participants with sensorimotor impairments who were able to wa...
Biomechanical assessment methods used in chronic stroke: A scoping review of no...
Freitas, Marta; Pinho, Francisco; Pinho, Liliana; Silva, Sandra; Figueira, Vânia; Vilas-Boas, João Paulo; Silva, AugustaNon-linear and dynamic systems analysis of human movement has recently become increasingly widespread with the intention of better reflecting how complexity affects the adaptability of motor systems, especially after a stroke. The main objective of this scoping review was to summarize the non-linear measures used in the analysis of kinetic, kinematic, and EMG data of human movement after stroke. PRISMA-ScR guid...

Freitas, Marta; Pinho, Francisco; Pinho, Liliana; Figueira, Vânia; Silva, Sandra; Sousa, Andreia S.P.; Silva, AugustaEnquadramento: : As alterações biomecânicas nos indivíduos após Acidente Vascular Cerebral (AVC) podem ser avaliadas em contexto clínico, com recurso a testes e escalas validadas, ou em contexto laboratorial através de uma análise instrumentada quantitativa e objetiva.. Objetivo: Identificar e sumariar os instrumentos de avaliação, e respetivas tarefas motoras, utilizados na análise do movimento humano, nas fas...
Photodegradable Non‐Drying Hydrogel Substrates for Liquid Metal Based Sustainab...
Fonseca, Rita G.; Hajalilou, Abdollah; Freitas, Marta; Kuster, Aline; Parvini, Elahe; Serra, Arménio; Coelho, Jorge; Tavakoli, MahmoudThe increasing interest in disposable electronics such as wearable patches, e-textiles, and smart packaging, warns emergence of another man-made disaster. A paradigm shift toward a more sustainable future through the development of soft material architectures that are robust and durable, but also degradable by external stimuli is proposed. Hydrogels, a class of soft polymers with exceptional properties, and hig...
