Topic 6 - disruptions in concussion Flashcards
what is the task switch task
touch the same side where colour appears = congruent
touch the opposite side where colour appears = incongruent
what is the effect on exec function in concussed youth
difficulty recovering exec function after injury and may require extended recuperation time before full recovery is achieved
longitudinal control group needed to make sure its recovery and not the learning effect
what are the results from the N-back test
- similar perf between groups on neurocognitive measure but the history of concussion group was less accurate on the 2-, 3-, and 4- back condition
- more suppression in history of concussion
- long term effects on exec function in history groups (even years following)
what are the differences between acute post concussion and clinically recovered in the KINARM
- less accurate with more deficits on non dominant side (accuracy and speed)
- likely due to changes in focus while dividing attention (focus on the dominant side because we know we’ll be better at it)
what does the addition of distractors in the kinarm test allow us to look at
response inhibition measures
- same differences between acute concussion and clinically recovered
- slower time with more symptoms
(younger groups usually have more symptoms)
what is the benefit of the kinarm
efficient means of obtaining objective, quantitative info about motor, sensory, and cognitive function
