Moving Standard Deviation of Trunk Acceleration as a Quantification Index for Physical Activities: Validation Study

Moving Standard Deviation of Trunk Acceleration as a Quantification Index for Physical Activities: Validation Study

Finally, we categorized all participants into 6 subgroups based on the mobility scores from the FIM and their mobility patterns as follows: FIM1-4, FIM5 WC, FIM5 walking, FIM6 WC, FIM6 walking, and FIM7. The Kruskal-Wallis test was performed to analyze the association between MSDA and the number of steps. The Bonferroni method was used to control for multiple comparisons. All analyses were performed using SPSS (version 26; IBM Corp).

A Smartphone-Based Timed Up and Go Test Self-Assessment for Older Adults: Validity and Reliability Study

A Smartphone-Based Timed Up and Go Test Self-Assessment for Older Adults: Validity and Reliability Study

An unsupervised smartphone-based i TUG could fill a gap in the landscape of mobility assessment methods that is still dominated by patient-reported outcome measures and supervised assessments conducted in laboratory or clinical settings [25]. Digital self-assessments could support older adults to take up an active role in risk screening or monitoring, and to early identify changes in their mobility.

Spatiotemporal and Behavioral Patterns of Men Who Have Sex With Men Using Geosocial Networking Apps in Shenzhen From Mobile Big Data Perspective: Longitudinal Observational Study

Spatiotemporal and Behavioral Patterns of Men Who Have Sex With Men Using Geosocial Networking Apps in Shenzhen From Mobile Big Data Perspective: Longitudinal Observational Study

Therefore, there is a pressing need for further research into the crucial HIV-related behaviors of these marginalized groups, particularly concerning mobility patterns and access to HIV testing.

Investigating the Magnitude and Persistence of COVID-19–Related Impacts on Affect and GPS-Derived Daily Mobility Patterns in Adolescence and Emerging Adulthood: Insights From a Smartphone-Based Intensive Longitudinal Study of Colorado-Based Youths From June 2016 to April 2022

Investigating the Magnitude and Persistence of COVID-19–Related Impacts on Affect and GPS-Derived Daily Mobility Patterns in Adolescence and Emerging Adulthood: Insights From a Smartphone-Based Intensive Longitudinal Study of Colorado-Based Youths From June 2016 to April 2022

Such data can capture features of daily routine mobility patterns, including their frequency, distance, duration, and regularity [23-26]. This research has identified widespread changes in mobility patterns following the pandemic’s onset and the implementation of lockdown policies, including fewer locations visited and shorter travel distance, and frequently a gradual recovery toward prepandemic mobility patterns following the first few months of the pandemic [27-33].

Smartphone Application–Based Voice and Speech Training Program for Parkinson Disease: Feasibility and Satisfaction Study With a Preliminary Rater-Blinded Single-Arm Pretest and Posttest Design

Smartphone Application–Based Voice and Speech Training Program for Parkinson Disease: Feasibility and Satisfaction Study With a Preliminary Rater-Blinded Single-Arm Pretest and Posttest Design

While the use of m Health apps for speech therapy in patients with PD is still in its early stages, there is potential for significant advancement through ongoing research and technological development. m Health offers great benefits in terms of accessibility and cost, especially for patients with PD who gradually experience reduced mobility, as it allows them to access therapy from anywhere with a mobile device [24-26].

Cross-Platform Ecological Momentary Assessment App (JTrack-EMA+): Development and Usability Study

Cross-Platform Ecological Momentary Assessment App (JTrack-EMA+): Development and Usability Study

Overall, our results demonstrate the potential to use our platform compared to the paper-and-pencil EMA assessment (which was shown to have a significantly lower compliance rate), particularly in participants with limited mobility or restricted access to health care services [24]. A limitation of our platform is its ability to detect and respond to various events and contexts, such as environmental and physical activities.

Mobility-Based Smartphone Digital Phenotypes for Unobtrusively Capturing Everyday Cognition, Mood, and Community Life-Space in Older Adults: Feasibility, Acceptability, and Preliminary Validity Study

Mobility-Based Smartphone Digital Phenotypes for Unobtrusively Capturing Everyday Cognition, Mood, and Community Life-Space in Older Adults: Feasibility, Acceptability, and Preliminary Validity Study

It is widely used to examine balance, functional mobility, gait speed, and fall risk in older adults [99,100]. Participants also completed the University of Alabama at Birmingham Life-Space Assessment (LSA), a self-report measure of mobility for community-dwelling older adults [101].

Using a Device-Free Wi-Fi Sensing System to Assess Daily Activities and Mobility in Low-Income Older Adults: Protocol for a Feasibility Study

Using a Device-Free Wi-Fi Sensing System to Assess Daily Activities and Mobility in Low-Income Older Adults: Protocol for a Feasibility Study

Therefore, it holds promise for application in scalable methods for monitoring the types and levels of daily activities and mobility among older adults. Wi-Fi sensing technology has been tested in the context of activity and gesture recognition, object sensing, and localization [30-34].
