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...

The performance of 2 or more attention demanding tasks simultaneously is poorly understood. purpose the study was to investigate optimal practice strategies for performing simultaneous tasks. Eighteen young adults walked and stepped over either a static dynamic obstacle, while responding an auditory Stroop test. Participants were randomly assigned 1 3 groups: one that practiced both simultaneously, only cognitive task, received no practice. Results indicate dual-task group showed...

The objective of this work was to investigate the influence perturbation direction has on postural responses during overground gait, and whether these are age related. Differences in stepping patterns following perturbations support surface were examined frontal sagittal planes forward walking. Eleven young 10 older adults completed Mini BESTest, hip strength tests, 45 perturbed walking trials, triggered heel contact. Lateral more challenging stability for both groups. Step length measures...

Electrical stimulation of the vestibular sensory system during virtual environment simulations has been proposed as a method to reduce incidence simulator adaptation syndrome (SAS). However, there is limited empirical evidence support this hypothesis. It especially important provide in driving simulators because an absence cues may alter driver behaviour and vehicle control. This study examined application galvanic (GVS) technique symptoms SAS improve vehicular control fixed-based simulator....

This study was designed to investigate the potential effects of kinesio tape on flexion-relaxation phenomenon, trunk postural control and position sense when applied for a short period (30 min) low back healthy female participants. Twenty-four participants were assigned one two groups: in either recommended stretched or non-stretched (control) manner over back. Tests performed at three time points (pre-tape, with tape, post-tape) assess low-back muscle flexion-relaxation, during active...
