Amyotrophic Lateral Sclerosis

Question 12

MEASURING BRAIN TRAUMA AND INJURY

Answer 12

-magnitude
-frequency
-interval
-duration

Question 13

Impact Characteristics associated with injury risk

Answer 13

• Location/angle –influences magnitude and direction of the dynamic response (linear and rotational)
• Compliance – influences magnitude and duration of the dynamic response
• Velocity –influences magnitude and duration of the dynamic response
• Mass – influences magnitude and duration of the dynamic response.
