Visual Strategies used during the performance of an obstacle course
Vision is the sense that provides precise information about one’s position in the environment in relation to objects. The visual system is essential to guide people safely when moving around in the environment. The perception that an individual gets from a particular scene of her/his surroundings is accomplished by eye movements. The current study aims to identify differences in visual strategi...
متن کاملReliability and concurrent validity of standardized walking obstacle course test in people with stroke.
OBJECTIVES To investigate: (i) the intra-rater, inter-rater and test-retest reliabilities of completion times and step counts on the Standardized Walking Obstacle Course test (SWOC); (ii) correlations between SWOC scores and stroke-specific impairments; (iii) the cut-off SWOC completion times and step counts for distinguishing differences in obstacle negotiation ability in people with chronic s...
متن کاملA standardized obstacle course for assessment of visual function in ultra low vision and artificial vision.
We describe an indoor, portable, standardized course that can be used to evaluate obstacle avoidance in persons who have ultralow vision. Six sighted controls and 36 completely blind but otherwise healthy adult male (n=29) and female (n=13) subjects (age range 19-85 years), were enrolled in one of three studies involving testing of the BrainPort sensory substitution device. Subjects were asked ...
متن کاملDetermination of Orientation and Practice Requirements When Using an Obstacle Course for Mobility Performance Assessment
OBJECTIVE Determine effect of orientation (introduction and familiarization) and practice (repeated performance) on human performance under various load conditions as assessed by an obstacle course. BACKGROUND Obstacle courses are commonly used as screening tools by military, police, and firefighters or to assess human capabilities and the effect of wearing personal protective equipment (PPE)...
متن کاملSorting by diffusion: an asymmetric obstacle course for continuous molecular separation.
A separation technique employing a microfabricated sieve has been demonstrated by observing the motion of DNA molecules of different size. The sieve consists of a two-dimensional lattice of obstacles whose asymmetric disposition rectifies the Brownian motion of molecules driven through the device, causing them to follow paths that depend on their diffusion coefficient. A nominal 6% resolution b...
