The Effects Of The Dual-Tasking: Walking While Texting On Slip Recovery Mechanics, Ileana Abril Jarquin
The Effects Of The Dual-Tasking: Walking While Texting On Slip Recovery Mechanics, Ileana Abril Jarquin
Open Access Theses & Dissertations
Introduction: The number of induced falls has increased exponentially over the last decade. Previous studies have determined that the cognitive demands of texting affect the processing of cognitive and motor tasks.Research question: What effect does the dual-tasking of texting and walking has on slip recovery mechanics? Methods: Three-dimensional kinematic data were collected while 20 participants between the ages of 18 and 30 years three different conditions; 1) baseline, 2) walking + slip perturbation, and 3) texting and walking + slip perturbation. Results: Walking speed, numbers of falls, and recovery time from the slip were not affected by the texting dual-task. …

Tripping is a common cause of falls across different age populations particularly in older adults. Concerns regarding the validity of simulated-fall research protocols reside in the current literature. The purpose of this study was to develop a novel treadmill-based tripping protocol that allowed researchers to deliver unanticipated tripping perturbations during walking with a high level of timing precision. The protocol utilized a side-by-side split-belt treadmill instrumented with force platforms. Treadmill belt acceleration profiles (two levels of perturbation severity: small perturbation vs large perturbation) were delivered unilaterally when the tripped leg bore 20% of the body weight during early stance. Peak …
