In developed countries, the aging population is increasing steadily, raising concerns related to healthcare and patient safety. One critical issue is the growing number of bed fall...
Turning over in bed, especially turning over at night, is a vital human unconscious behavior. Clinically, this movement disperses pressure between the body and bed, thus preventing...
Blood oxygen saturation (SpO2) is one of the most important vital sign parameters. The conventional measurement method is contact-based photoplethysmography (PPG), which includes f...
Itch is an unpleasant sensation that evokes the urge to scratch and can lead to reduced concentration, sleep disturbances, and decreased quality of life. Conventional assessment me...
Early decompression for traumatic spinal cord injury (SCI) benefits neurological recovery, yet executing timely surgery demands precise, safe bone cutting adjacent to the cord. We ...
Accurate detection of swallowing events is essential for objective assessment of swallowing function and long-term monitoring in daily living environments. In this study, we propos...
This study applies the attractor reconstruction method to photoplethysmography (PPG) signals to explore their potential in preventive health monitoring. Conventional PPG analysis m...
Building on our previous findings that once-weekly high-intensity exercise, whether performed as a single bout or as three-set intervals, effectively improves cardiorespiratory fun...
This study used electroencephalography (EEG) and Representational Similarity Analysis (RSA) to investigate whether the neural representation of a concept built from a descriptive s...
Electroencephalogram (EEG) signals are critical for detecting abnormal brain activity, but their high dimensionality and complexity pose significant challenges for effective analys...
Goal: The variability in soft organ shapes and positions across patients poses challenges for linear models in the reconstruction of significant local variations, while nonlinear m...
Skin barrier function has been quantitatively evaluated through trans-epidermal water loss, which has been difficult to measure in clinical settings owing to environmental factors ...
Measuring neural activity during communication is essential for understanding social brain processes and contributes to improving the diagnosis and treatment of communication disor...
Magnetoencephalography with optically pumped magnetometers (OPM-MEG) has become a focus of research. Signal sources can be estimated using OPM-MEG, where the sources are approximat...
Cognitive training can improve specific abilities, yet little is known about how trainees adapt their visual strategies and how such adaptations relate to behavior and brain functi...
This study examined the effects of flat-soled footwear on toe function and muscle mass in middle-aged adults. In a two-month intervention study, participants aged 50 and older were...
Standard methods for evaluating swallowing function, such as videofluoroscopic swallowing studies and fiberoptic endoscopic evaluation, are invasive and environment-dependent. In o...
The emergence of autonomous driving is becoming a reality worldwide. However, in emergency situations, human drivers must assume control of the vehicle, hence detecting driver vigi...
An increasing number of individuals in aging populations are affected by urination disorders such as benign prostatic hyperplasia and overactive bladder. Bladder diaries are widely...
