Reducing trailing limb collisions in older adults through targeted leading limb placement after obstacle crossing
The collision rate for the trailing limb in the closer group was significantly lower in the post-test than that in the pre-test. Furthermore, the variability in toe height and walking speed of the trailing limb in the closer group decreased significantly in the post-test compared to the pre-test. These findings suggest that the intervention of placing the leading limb foot closer to the obstacle after crossing may improve obstacle avoidance by th…
Enhancing collision prediction in older adults via perceptual training in virtual reality emphasizing object expansion
Introduction The ability to predict collisions with moving objects declines with age, partly due to reduced sensitivity to object expansion cues. This study examined whether perceptual training specifically targeting object expansion improves collision prediction more effectively than repeated practice on an identical collision prediction task. Additionally, the study verified whether such training could be employed to improve prediction accuracy…
How far along the future path do individuals recognize the path for stepping on multiple footfall targets? A new evaluation method under virtual reality
Introduction The ability to visually recognize the path ahead during walking is essential for adjusting gait patterns in an anticipatory manner to mitigate perturbations induced by tripping. In this study, we aimed to develop a walking task within a virtual reality (VR) environment, termed the VR multi-target stepping (VR-MTS) task, as a method to evaluate the extent to which individuals can recognize the path ahead while continuously stepping on…
Motor flexibility to stabilize the toe position during obstacle crossing in older adults
Introduction An age-related decrease in the ability to exploit the abundant degrees of freedom of the body, referred to as motor flexibility, leads to a heightened fall risk. The present study investigated motor flexibility to stabilize the toe position during obstacle crossing in older adults and its correlation with the magnitude of foot elevation. Methods Twenty-six older adults (70.9 ± 7.4 years old) and 21 younger adults (25.4 ± 5.0 years ol…
Placing the leading limb closer to an obstacle reduces collision of the trailing limb
IntroductionWhen walking and stepping over an obstacle of a certain height, tripping occurs more frequently with the trailing limb than the leading limb. The present study was designed to address whether collisions involving the trailing limb can be improved with experimental manipulation of the placement of the leading limb after stepping over an obstacle. We used an immersive, virtual obstacle-crossing task to ensure that the collision was not …
Improved Walking Through an Aperture in a Virtual Environment Transfers to a Real Environment
Virtual reality (VR) could be used to set up a training protocol to improve one's collision-avoidance behavior. In our previous study, we developed a VR system for training older individuals to walk through an aperture in a manner that is both safe (i.e., no collision) and efficient (i.e., no exaggerated behavior to ensure collision avoidance). In the present study, we made several modifications to the VR system in terms of enriched feedback (vib…
Haptic feedback intervention decreases the spatial margin when older adults walk through a narrow space
Background The ability to avoid obstacles efficiently and safely is important for older adults to prevent injuries from tripping and falling. It is important to find an optimal spatial margin between the body and an obstacle considering both safety and efficiency. One side of finding the optimal margin is to decrease the margin in terms of motor efficiency. In this study, we tested whether fingertip-contact intervention to obtain haptic feedback …
Eye gaze differences in school scenes between preschool children and adolescents with high-functioning autism spectrum disorder and those with typical development
BACKGROUND: Children with autism spectrum disorder (ASD) may experience difficulty adapting to daily life in a preschool or school settings and are likely to develop psychosomatic symptoms. For a better understanding of the difficulties experienced daily by preschool children and adolescents with ASD, this study investigated differences in eye gaze behavior in the classroom environment between children with ASD and those with typical development …
Changes in Self-estimated Step-Over Ability Among Older Adults
Objectives There is a growing body of literature examining age-related overestimation of one’s own physical ability, which is a potential risk of falls in older adults, but it is unclear what leads them to overestimate. This study aimed to examine 3-year longitudinal changes in self-estimated step-over ability, along with one key risk factor: low frequency of going outdoors (FG), which is a measure of poor daily physical activity. Method This coh…
Perception of spatial requirements for wheelchair locomotion in experienced users with Tetraplegia
This study focused on whether wheelchair users showed enhanced ability to estimate the space required for locomotion with familiar and unfamiliar wheelchairs. Tetraplegic participants, who lacked somatosensory input from the upper limbs and were unable to obtain information about the dimensions of a wheelchair from their hands, and able-bodied control participants made judgments of whether a doorway was passable with their usual form of locomotio…
Action‐oriented representation of peripersonal and extrapersonal space
This paper reviews behavioral evidence demonstrating that space is accurately represented in the brain in relation to action capabilities. We initially review intriguing neuropsychological findings that show that space is differentially represented depending on whether the area is in reach of the hand (peripersonal space) or out of reach of the hand (extrapersonal space). We then review the literature on the characteristics of locomotor actions f…
Multidimensional scaling of fragrances
Higuchi, Shoji, and Hatayama (2002 ) selected nine sense‐descriptive adjectives (e.g., sweet, clear) to describe the olfactory properties of fragrances. In order to clarify the ability of these adjectives to classify fragrances, the present study used a non‐verbal sorting of fragrances that has been widely accepted in previous studies as a method of classifying fragrance. Interfragrance similarities obtained from the non‐verbal sorting were then …
Disruption of kinematic coordination in throwing under stress
The present study tested the conscious‐control theory of the relationship between stress and performance. Performers under stress conditions consciously attempted to control their movements, disrupting the automaticity of control. Twenty‐two male subjects (11 in Experiment 1 and 11 in Experiment 2) performed an underhand ball‐throwing task using the non‐dominant hand. The inter‐trial variability of two kinematic measures was analyzed, namely arm‐…
