Brain Injury Biomechanics Flashcards
(4 cards)
1
Q
What is the difference between linear and rotational acceleration in brain injury?
A
Linear causes pressure changes, while rotational causes shearing and diffuse axonal injury.
2
Q
What is the purpose of instrumented mouthguards?
A
They provide real-time head impact kinematic data, improving concussion monitoring in sports.
3
Q
How does neck strength influence concussion risk?
A
Greater neck strength reduces head acceleration during impact, lowering concussion risk by stabilising the head-neck segment.
4
Q
What key risk factor contributes to Achilles tendon rupture in middle-aged athletes?
A
Sudden high loading in an unconditioned tendon, often following inactivity.
Example: “weekend warrior” injuries.
