Summary: Inpatient gait analysis is crucial for rehabilitation of foot amputees, and the ground contact time (GCT) difference between legs is an important factor. This study presents a wearable sensor system called Suralis, which utilizes algorithms to calculate GCT based on data collected from an inertial measurement unit (IMU) and a pressure measuring sock. The results show that the algorithms have a median GCT error of -51.7 ms (IMU) and 14.7 ms (sensor sock), making it a suitable option for wearable gait analysis. The system enables continuous feedback for patients and remote diagnosis of spatio-temporal aspects of gait behavior.

Summary: This study aimed to investigate gait disorders in patients with mild cognitive impairment (MCI) and examine the association between gait performance and cognitive function. By measuring gait parameters using wearable sensors, the study found that MCI patients exhibited more pronounced gait disorders when performing additional cognitive tasks, and temporal gait parameters were found to be associated with cognitive function. Particularly, the words recall test had a greater impact on gait regularity, velocity, and dual task cost. Gait assessment, especially in the words recall test, using portable sensors could be a useful complementary strategy for early detection of MCI.

Summary: Aging is a significant challenge in society, and wearable solutions for telemonitoring biological signals are seen as a way to improve older adults' healthcare. This study reviewed the remote monitoring of biological signals in older adults using technology. Systematic reviews and meta-analyses published between 2016 and 2022 in English, Portuguese, or Spanish were considered. Most frequently measured variables were heart and respiratory rate, physical activity, electrocardiography, body temperature, blood pressure, glucose, and heart rate. These were monitored using wearables placed on the waist, wrist, or ankle. Psychometric properties of the systems were generally valid and accurate. Environmental signals were less frequently studied, with luminosity, temperature, and movement being the most mentioned variables. The need for larger-scale studies with longer durations was highlighted to assess the feasibility of wearable devices for telemonitoring.

Summary: The research demonstrates that shank-mounted IMUs can be used to detect gait events during straight-line walking, slalom walking, and turning. However, more false events were observed during turning and more events were missed during turning. It is recommended to identify turning before extracting temporal gait parameters from identified gait events for use in daily life.

Summary: The majority of digital technologies for health promotion are designed for individuals, with limited adaptation to social life constellations such as families. This study aimed to identify the needs and requirements for an audience-oriented app development in the context of families. Through an online survey with 1008 parents, the researchers assessed the health status, exercise, nutrition, relaxation, smartphone use, app features, and gamification preferences. The results revealed that most participants considered their health to be good, but only a minority met the recommended levels of physical activity and nutrition. The identified target areas for a health app in families included active relaxation measures, nutrition, general competence, physical activity, nature activities, and sports-recreation opportunities. The study concluded that there is a need for digital support in behavior change processes within families, and future research should explore usage preferences for health apps in different family constellations.
