Thus, embracing and maintaining healthy behaviours work like a preventive action, avoiding or delaying the emergence of chronic diseases. The process of changing daily routines toward healthy behaviours starts by understanding the current problems. Wearable and deep learning (DL) technologies represent important resources for supporting such an understanding. This paper discusses a strategy to interpret multifeatured longitudinal wearable data to analyse possible causes of health issues. We use the sleep domain as a case example where the aim is to clarify the reasons for poor sleep quality. A dataset with wearable data of 1874 days was used to create an explainable DL model, which indicates the main day-before-night sleep behaviours that may cause poor sleep quality. We use a comparative analysis with a hormone-based framework for sleep control as the form of validation. The results show that the explanations corroborate the results of the literature. However, other datasets with more features should be explored to verify the combination of these features and their effects on the health aspect under study.</p>","PeriodicalId":72237,"journal":{"name":"Annual International Conference of the IEEE Engineering in Medicine and Biology Society.

We developed a novel transcutaneous cannulation-type mechanical circulatory system for an alternative therapeutic approach to cardiac arrest using a small centrifugal blood pump. We proposed a transcutaneous mechanical circulatory support capable of rapid installation and quick start of circulatory support for recovery after cardiac arrest by left ventricular direct puncture using the Seldinger technique. The cannula consisted of three components as follows: a) a double-layered cylindrical blood pump housing, b) a centrifugal blood pump impeller primarily installed inside of the cannula, and c) an insertable actuator with magnet coupling. The special feature of the cannula inflow was a backflow resistive unit for adjusting backflow in the process of ventricular puncture. In this study, we performed an in vivo experiment to install the direct cannulation centrifugal blood pump on a goat after cardiac arrest induced by ventricular fibrillation as a proof of concept. As a primary result, the mechanical circulatory support could start in a short period by around one minute installation from the start of cannulation, which could be effective for the recovery after cardiac arrest under the assisted flow of 1.6 L/min at 13,000 rpm of the cannulation pump. Consequently, the novel approach may be useful for the prompt start of mechanical circulatory support.</p>","PeriodicalId":72237,"journal":{"name":"Annual International Conference of the IEEE Engineering in Medicine and Biology Society.

This study aims to explore whether HRV could demonstrate progression of mindfulness through repeated practice. 20 experienced practitioners and 26 novices were enrolled to practice two-week mindfulness and completed the Five Facet Mindfulness Questionnaire pre and post the training. ECG signals were collected by holter monitors, covering baseline to training and 9 HRV metrics were extracted. The results indicate that the experienced group showed significantly increased parasympathetic activity during mindfulness training and the effects were stable through repeated practice, while the novice group showed high cognitive load, with inconspicuous but probably progressive effects.

It not only leads to impaired motor control and pain but also lowers the quality of life for stroke patients. Botulinum toxin (BoNT) injection has been used as a first-line treatment for spasticity, which helps to reduce muscle tone. While the Modified Ashworth Scale (MAS) is the current clinical gold standard in evaluating spasticity, it can be affected by low inter-rater reliability. This study aims to evaluate the efficacy of high-density surface electromyography (HD-sEMG) in the passive stretch reflex pre- and post-BoNT injection as a biomarker for spasticity detection and monitoring. Ten stroke participants were recruited in this study, and the root mean squared (RMS) envelope signal and the slope between fast passive extension (FPE) and slow passive extension (SPE) were calculated. The results show that all participants have Peak RMS Envelope and Slope features lower Post-BoNT injection compared to Pre-BoNT injection (SPE: p=0.03938; FPE: p=0.00119; Slope: p=0.00143 while only five out of ten participants have their MAS Score reduce after BoNT injection (p=0.02386).

The existing rehabilitative systems constrain the patient to move with the system, making it difficult for the patient to eventually perform the movement independently without facing resistance from the system. This paper proposes the design of an STS rehabilitation system that assists subjects only in the parts of the motion that they fail to perform independently. The assistance is provided in a two-phase process and allows subject to attempt different levels of difficulty dynamically without having to select a target difficulty level before the start of the therapy session.

A new yet under-explored BCI control paradigm is Motion Trajectory Prediction (MTP). While MTP provides continuous control signals suitable for high-precision tasks, its feasibility and applications are challenged by the low signal-to-noise ratio, especially in noninvasive settings. Previous research has predominantly focused on kinematic reconstruction of upper (e.g., arm reaching) and lower limbs (e.g., gait). However, finger movements have received much less attention, despite their crucial role in daily activities. To address this gap, our study explores the potential of noninvasive Electroencephalography (EEG) for reconstructing finger movements, specifically during hand grasping actions. A new experimental paradigm to collect multichannel EEG data from 20 healthy subjects, while performing full, natural hand opening and closing movements, was designed. Employing state-of-the-art deep learning algorithms, continuous decoding models were constructed for eight key finger joints. The Convolutional Neural Network with Attention approach achieved an average decoding performance of r=0.63. Furthermore, a post-hoc metric was proposed for hand grasp cycle detection, and 83.5% of hand grasps were successfully detected from the reconstructed motion signals, which can potentially serve as a new BCI command. Explainable AI algorithm was also applied to analyze the topographical relevance of trained features. Our findings demonstrate the feasibility of using EEG to reconstruct hand joint movements and highlight the potential of MTP-BCI in control and rehabilitation applications.</p>","PeriodicalId":72237,"journal":{"name":"Annual International Conference of the IEEE Engineering in Medicine and Biology Society.
