Biofeedback-based method for real-time fatigue monitoring of knee
Franco, Tiago; Henriques, Pedro; Alves, Paulo; Pereira, Maria João; Leitão, Paulo; Azevedo, NelsonThis paper introduces and implements a method to monitor muscle fatigue in real-time using a wearable biofeedback system to improve muscle rehabilitation treatments. The biofeedback system consists of an electromyography (EMG) sensor to capture muscle activity and two motion sensors to track knee angles. The proposed method for monitoring muscle fatigue involves three steps: (1) recognition of the movement phas...
Automatic Fall Detection with Thermal Camera
Kalbermatter, Rebeca B.; Franco, Tiago; Pereira, Ana I.; Valente, António; Soares, Salviano Pinto; Lima, JoséPeople are living longer, promoting new challenges in healthcare. Many older adults prefer to age in their own homes rather than in healthcare institutions. Portugal has seen a similar trend, and public and private home care solutions have been developed. However, age-related pathologies can affect an elderly person’s ability to perform daily tasks independently. Ambient Assisted Living (AAL) is a domain that u...
Titanium based dry electrodes for biostimulation and data acquisition
Conselheiro, Raul; Lopes, Claudia; Azevedo, Nelson; Leitao, Paulo; Agulhari, Cristiano; Veloso, H.; Vaz, F.; Gonçalves, João Lucas; Franco, TiagoWet electrodes rely on conductive electrolyte gel for proper perfor- mance, usually presenting high setup time and being disposable or requiring time-consuming cleaning methods. Skin irritation and signal quality deterioration are some of the problems that may occur with these electrodes. Therefore, to overcome these drawbacks, 3D printed bases using Fused Deposition Modelling (FDM) with Polylactic acid (PLA), ...
Motion sensors for Knee angle recognition in muscle rehabilitation solutions
Franco, Tiago; Oliveira, Leonardo Sestrem de; Henriques, Pedro Rangel; Alves, Paulo; Pereira, Maria João; Brandão, Diego; Leitão, Paulo; Silva, AlfredoThe progressive loss of functional capacity due to aging is a serious problem that can compromise human locomotion capacity, requiring the help of an assistant and reducing independence. The NanoStim project aims to develop a system capable of performing treatment with electrostimulation at the patient’s home, reducing the number of consultations. The knee angle is one of the essential attributes in this contex...
Decision support system for NMES treatments : a solution design
Franco, TiagoThe preservation of functional capacity in old age is associated with a more active and dignified life. Maintaining this capacity is not a trivial task; several diseases can make it difficult to practice regular physical exercises or make it unfeasible, such as knee osteoarthritis. Neuromuscular electrical stimulation (NMES) is a treatment for muscle rehabilitation positioned as an alternative. However, it is s...
Data acquisition, conditioning and processing system for a wearable-based biost...
Oliveira, Leonardo Sestrem de; Kaizer, Raul; Gonçalves, João; Leitão, Paulo; Teixeira, João Paulo; Lima, José; Franco, Tiago; Carvalho, José AugustoData acquisition by electromyography, as well as the muscle stimulation, has become more accessible with the new developments in the wearable technology and medicine. In fact, for treatments, games or sports, it is possible to find examples of the use of muscle signals to analyse specific aspects related, e.g., to disease, injuries or movement impulses. However, these systems are usually expensive, does not int...
Anomaly detection using smart shirt and machine learning: a systematic review
Nunes, Eduardo; Barbosa, José; Alves, Paulo; Franco, Tiago; Silva, AlfredoIn recent years, the popularity and use of Artificial Intelligence (AI) and significant investments in the Internet of Medical Things (IoMT) will be common to use products such as smart socks, smart pants, and smart shirts. These products are known as Smart Textile or E-textile, which can monitor and collect signals that our body emits. These signals allow it to extract anomalous components using Machine Learni...
System architecture for home muscle rehabilitation treatment
Franco, Tiago; Henriques, Pedro Rangel; Alves, Paulo; Pereira, Maria João; Pedrosa, Tiago; Silva, F.; Leitão, Paulo; Oliveira, L.The constant loss of functional capacity due to aging is a serious problem that can severely worsen the quality of life. Among the possible treatments, muscles electrostimulation can be a viable option because it is cheap and easy to access. With the evolution of wearable devices and the Internet of Things, this paper proposes a system architecture that enables an electrostimulation treatment to be performed at...
myHealth: a mobile App for home muscle rehabilitation
Franco, Tiago; Henriques, Pedro Rangel; Alves, Paulo; Pereira, Maria João; Oliveira, Leonardo Sestrem de; Leitão, Paulo; Silva, AlfredoThe constant loss of functional capacity due to aging can lead to a less active and dignified life, especially if the necessary care is not taken. One of the treatments for muscle rehabilitation is electrostimulation, but it may require two or three visits to the clinic per week. In this paper is proposed a mobile application that serves as a key for minimizing the number of visits to the clinic. The proposed t...
