SARS-CoV-2 infection can lead to a variety of persistent sequelae, collectively known as long COVID-19. Deficits in postural balance have been reported patients several months after COVID-19 infection. The purpose this study was evaluate the static and individuals with using inertial sensors smartphones. A total 73 participants were included study, which 41 had 32 served controls. All group physical complaints for at least 7 Participants evaluated built-in sensor smartphone attached low back, recorded signals during mobility task (timed up go test). parameters obtained from both groups compared. matched age BMI.

Patients recovering from a stroke experience reduced participation, especially when they are limited in daily activities involving walking. Understanding the recovery of independent walking, can be used by clinicians decision-making process during rehabilitation, resulting more personalized rehabilitation. Therefore, it is necessary to gain insight predicting walking patients after stroke. This systematic review provided an overview current evidence about prognostic models and its performance predict MEDLINE, CINAHL, Embase were searched for all relevant studies English Dutch.

Real-World Balance Assessment While Standing for Fall Prediction in Older Adults

IEEE Transactions on Biomedical Engineering, Journal Year: 2023, Volume and Issue: 71(3), P. 1076 - 1083

Published: Oct. 20, 2023

Objective: Postural control naturally declines with age, leading to an increased risk of falling. Within clinical settings, the deployment balance assessments has become commonplace, facilitating identification postural instability and targeted interventions forestall falls among older adults. Some studies have ventured beyond controlled laboratory, leaving, however, a gap in our understanding real-world scenarios. Methods: Previously reported algorithms were used build finite-state machine (FSM) four states: walking, turning, sitting, standing. The FSM was validated against video annotations (gold standard) independent dataset data collected on 20 Later, applied from 168 community-dwelling people InCHIANTI cohort who evaluated both laboratory then remotely conditions for week. A 70/30 split recursive feature selection resampling techniques train test machine-learning models. Results: In identifying fallers, duration, distance, mean frequency computed during standing settings revealed significant relationships fall risk. Also, best-performing model (Lasso Regression) built features had higher area under curve (AUC, 0.76) than one lab-based (0.57). Conclusion: Real-world differ considerably (Romberg test) predictive capacity patients at high Significance: These findings highlight need move traditional laboratory-based measures develop more sensitive accurate methods predicting falls.

Digital Biomarkers of Gait and Balance in Diabetic Foot, Measurable by Wearable Inertial Measurement Units: A Mini Review

Sensors, Journal Year: 2022, Volume and Issue: 22(23), P. 9278 - 9278

Published: Nov. 29, 2022

People with diabetic foot frequently exhibit gait and balance dysfunction. Recent advances in wearable inertial measurement units (IMUs) enable to assess some of the dysfunction associated (i.e., digital biomarkers balance). However, there is no review inform related foot, measurable by IMUs (e.g., what parameters can collect? Are measurements repeatable?). Accordingly, we conducted a web-based, mini using PubMed. Our search was limited human subjects English-written papers published peer-reviewed journals. We identified 20 this review. found preliminary evidence people such as slow speed, large variability, unstable initiation, body sway. due heterogeneities included terms study design, movement tasks, small sample size, more studies are recommended confirm evidence. Additionally, based on our review, recommend establishing appropriate strategies successfully incorporate wearable-based assessment into clinical practice for care.

Published: Jan. 1, 2024

Objective : Balance plays a crucial role in human life and social activities. Maintaining balance is relatively complex process that requires the participation of various control subsystems (BCSes). However, previous studies have primarily focused on evaluating an individual's overall ability or each BCS isolation, without considering how they influence (or interact with) other. xmlns:xlink="http://www.w3.org/1999/xlink">Methods The first study used clinical scales to evaluate functions four BCSes, namely Reactive Postural Control (RPC), Anticipatory Adjustment (APA), Dynamic Gait (DG), Sensory Orientation (SO), psychological factors such as fear falling (FOF). A hierarchical structural equation modeling (SEM) was investigate relationship between BCSes their association with FOF. second involved using posturography measure extract parameters from center pressure (COP) signal.
