topic 12 - research findings

Question 1

what is the dynamic recursive model

Answer 1

extrinsic factors = practise vs game, equipment, rules, type of sport

intrinsic factors = previous concussion, player weight (modifiable), pre existing symptoms, NM control

both can be targeted in primary prevention

Question 2

what is the epidemiological model

Answer 2

1. Surveillance - extent of injury problem (did the prevention strategy make a difference?)
2. Find the risk factors - cause
3. Develop an intervention - validation
4. Introduce the intervention - implementation

Question 3

what WAS the #1 cause of injury in youth hockey

Answer 3

body checking

Question 4

how did injury rates in youth hockey change

Answer 4

rule changes, equipment recommendations, and training strategies

reduced body checking = estimated reduction of >4800 concussions in canada in 11-12yo

seen in all age brackets

Question 5

how is policy change informed

Answer 5

partnerships and knowledge translation

Question 6

what was the highest incidence of concussion in volleyball

Answer 6

ball to head in warmup (not paying attention)

(mix of ball to head and player to player in competition)

Question 7

what is the effect of mouthguard use

Answer 7

60% reduction
better with off the shelf mouthguards

Question 8

what is the effect of helmet fit

Answer 8

proper fit = reduced risk of concussion compared to improper fit

Question 9

what reduces head impacts in football training

Answer 9

limiting contact practises
combining ^ with coach training for techniques and warmups = larger reduction

Question 10

what is the effect NMT warmups

Answer 10

proper warmup = ideally can avoid some injuries
