Busy walking paths, like in a park, city centre, or shopping mall, frequently necessitate collision avoidance behaviour. Lab-based research has shown how different situation- and person-specific factors, typically studied independently, affect What happens the real world is unclear. Thus, we filmed unscripted pedestrian behaviours on busy urban path. We leveraged deep learning algorithms to identify extract trajectories had unbiased raters characterize situations where two pedestrians...

The purpose of this research was to assess cortical excitability, voluntary activation muscle and force sensation beyond the initial highly symptomatic period post-concussion (1-4 weeks post-injury). It hypothesized that reduced excitability motor cortex may impair alter perceptions effort.Eight concussed varsity football players were age- position-matched with eight healthy teammates control for training body size. Healthy controls had not suffered a concussion in previous 12...

BACKGROUND Transcatheter aortic valve replacement (TAVR) can be performed through multiple access sites with the preferred approach being transfemoral. In patients severe peripheral arterial disease and previous grafts, safety of transfemoral via direct graft puncture, especially when twice within a short period, remains unclear compared to alternative methods. We present case demonstrating efficacy puncture for during balloon valvuloplasty (BAV) TAVR. CASE SUMMARY An 82-year-old man...

Humans use visual information to safely guide locomotion avoid collisions with objects or other people within cluttered environments. The purpose of the current study was examine head-on mutual avoidance behaviours two young adults when approaching an aperture from opposite sides. It hypothesized that are on a collision course, both pedestrians would accurately perceive difference in arrival time between one another predict and maintain passing order through aperture. Nineteen (x¯=21.35±0.49...

<title>Abstract</title> Previous research suggests exercise improves spatial navigation abilities, though the effects of different intensities on this cognitive function have not been explored. The current study assessed influence moderate-intensity and high-intensity acute learning memory, focusing acquisition survey route knowledge in young adults. Thirty-two participants (22.6 ± 1.7 y) were randomly assigned to one three groups: 1) no-exercise control (n = 10); 2) continuous training...

Current protocols for returning athletes to play (RTP) center around resolution of physical symptoms concussion. However, recent research has identified that balance and cognitive deficits persist beyond symptom recovery. Protocols involve testing dynamic visuomotor integration have been recommended as potential tools better understanding length impairment following A dynamic, paradigm was undertaken in the current study assess decision making who had sustained a concussion >30 days before...

The current study examined whether young adults' avoidance behaviours differed when circumventing a larger versus smaller interferer. It was expected that (repulsion) would be affected by the interferer's size (i.e., greater repulsion for body size). Participants (n = 20) walked along an 8 m pathway towards goal while avoiding either or sized male interferer who stood stationary facing forward, backward, left, right and were located 2, 4, 6 from participants' starting position. Results...

ABSTRACT Busy walking paths, like in a park, sidewalk city centre, or shopping mall, frequently necessitate collision avoidance behaviour. Lab-based research has shown how variety of situation-specific factors (e.g., distraction, object/pedestrian proximity) and person-specific pedestrian size, age), typically studied independently, affect What happens the real world is unclear. Thus, we filmed unscripted behaviours on busy ∼3.5 m urban path adjacent to water. We leveraged deep learning...

The objectives of the current study were: (a) to determine whether perception-action coupling controlled behaviours when walking through moving doors and (b) how vision contributed this behaviour. Participants (N = 6) walked along a 7-m path toward two motor-driven doors, which moved at rates ranging between 20 40 cm/s. Each door was independently driven such that both same velocity (symmetrical) or different velocities (asymmetrical). results showed in movement conditions participants their...

When passing through apertures, individuals scale their actions to shoulder width and rotate shoulders or avoid apertures that are deemed too small for straight passage. Carrying objects wider than the body produces a person-plus-object system must account in order pass safely. The present study aimed determine whether critical point widest horizontal dimension (shoulder object width). Two responses emerged: Fast adapters adapted by maintaining consistent regardless of was carried while slow...

Walking through cluttered environments is a requirement of everyday locomotion, and individuals will walk toward open space adjust their actions in order to prevent injury. When walking confined space, require shoulder rotation pass apertures smaller than 1.3 times widths. The current study aimed identify the action strategies employed by young adults avoid contacting two obstacles placed travel path when nonconfined space. Participants (N = 12) walked along 10-m towards goal while avoiding...
