[Purpose] The purpose of this study was to investigate gait velocity and center of mass (COM) during square and semicircular turning gaits between two groups of elderly people with differing visual acuity. [Subjects] Twenty elderly Korean women who could walk independently and who lived in the community were recruited. [Methods] We measured gait velocity and COM using an accelerometer during two different turning gaits. [Results] The velocity during square and semicircular turning gaits of participants with good binocular visual acuity (GBVA) was significantly higher than that of participants with poor binocular visual acuity (PBVA). The COM during square and semicircular turning gaits of the GBVA group was significantly decreased compared with that of the PBVA group. [Conclusion] These findings suggest that visual acuity affects velocity and COM during square and semicircular turning gaits of elderly people.

Objectives: This study aims to objectively evaluate turning gait parameters in Parkinson disease (PD) patients using 2D-RGB video-based analysis and explore their relationships with imbalance.

Methods: We prospectively enrolled PD patients for clinical assessments, balance analysis and gait with 180' turning. Spatiotemporal gait parameters during turning were derived based on video-based analysis and correlated with modified Hoehn and Yahr (mHY) stages and center of pressure (COP) oscillations.

Background: The efficacy of subthalamic stimulation on axial signs of Parkinson's disease (PD) is debated in the literature. This study delves into the dynamic interplay of gait and posture, specifically probing their nuanced response to subthalamic stimulation and levodopa.

Methods: We used wearable sensor technology to examine alterations in the spatiotemporal parameters of gait and posture in individuals with PD before and 6 months after subthalamic deep brain stimulation (STN-DBS) surgery.

This study aims to elucidate the biomechanical characteristics of turning in daily life by analyzing the three-step process of approach, turn, and departure phases. The research involved ten healthy young individuals performing straight walking and 90° turns, categorized into Side-Step (SS) and Cross-Step (CS) turns. Using a 17-camera motion capture system and force plates, the study measured joint angles, moments, and center of mass (COM) variations.

Simultaneous Localization and Mapping Methods for Snake-like Robots Based on Gait Adjustment.

Snake robots require autonomous localization and mapping capabilities for field applications. However, the characteristics of their motion, such as large turning angles and fast rotation speeds, can lead to issues like drift or even failure in positioning and map building. In response to this situation, this paper starts from the gait motion characteristics of the snake robot itself, proposing an improved gait motion method and a tightly coupled method based on IMU and visual information to solve the problem of poor algorithm convergence caused by head-shaking in snake robot SLAM.

Background: The Dual-task Augmented Reality Treatment (DART) trial recently established that dual-task training (DTT) delivered by a physical therapist or the augmented reality DART platform was effective in improving spatiotemporal gait parameters under single- and dual-task conditions in individuals with Parkinson's disease (PD). Data regarding postural stability were not reported in the primary outcome manuscript.

Objective: The aim of this secondary analysis was to compare the effects of a Traditional DTT intervention delivered by a physical therapist and DTT delivered by the DART platform on postural stability, functional mobility, and turning in individuals with PD.
