Healthy Active Living and Sports Flashcards
What is a concussion?
- brain injury
- complex pathophysiological process affecting the brain induced by biometrical forces and resulting in the rapid onset of short-lived impairment of neurological function that resolves spontaneous
What causes a concussion?
- direct impact to the head, neck or face or to somewhere’s on the body that transmits an impulsive force to the head
- LOC is not common
What are some signs and symptoms of concussion?
- h/a,
- N/V
- dizziness
- photophobia, phonophobia
- LOC
- amnesia
- loss of balance or coordination
- decreased playing ability
- irritability
- emotional lability
- sadness, anxiety
- in appropriate emotions
- slowed reaction times
- trouble concentrating
- difficulty remembering
- confusion
- feeling dazed or in a fog
- drowsiness
- trouble falling asleep
- sleeping more or less than usual
When do symptoms of a concussion develop?
-usually in minutes to hours but can be up to days following the injury
When do symptoms of a concussion typically resolve?
usually 7-10 days but for some it is weeks to months
What is second impact syndrome?
-fatal diffuse cerebral swelling
What should you do if you have a concussion?
- stop the activity right away
- see a MD for neurological and cognitive assessment as soon as possible to confirm the dx
What are some factors that might put you at risk for a longer recovery phase following a concussion?
- previous head or facial injury
- hx fo h/a or migraines in the pt or family
- mental health issues
- sleeping difficulties
- learning disabilities
- ADHD
What do you tell parents about monitoring immediately after a concussion?
- be closely monitored for 24 to 48 hours for signs of deterioration
- sleep is important but they should be checked on through the night but not woken up unless concern about deterioration
What imaging do you need for concussion?
usually none, unless suspect a structural injury
What is the role of neuropsychological testing in concussion?
- can be helpful for return to play guidelines but not usually feasible
- may be necessary for athletes who have sustained multiple concussions or who experience prolonged post concussive symptoms to help identify specific deficits and aid with educational planning
What is the Return to Learn protocol for concussion?
-different stages and if symptoms worsen at any stage go to the one before
Cognitive rest - decrease and limit cognitive tasks including screen time; no school
increase cognitive tasks - slow increase cognitive tasks at home in 15-20 min increments
Resume modified school attendance - start with half days or only certain classes (avoid gym, music, shop) limit homework assignments to 15-20 min blocks
Increase school attendance - gradually increase to full days as symptoms allow; specific accommodations may be required; tests should be limited to one per day in a quiet area with unlimited time and frequent breaks
Return to play protocol - once symptom free and back in full-time school without accommodations the student can start with graduated return to play
What kind of accommodations are made for students with concussion in school?
- frequent breaks, quiet area, hydration
- shortened day, only certain classes
- if photo or phono phobia - sunglasses, ear plus, avoid noisy areas, limit computer work
- reassurance and support from teachers
- shorter assignment, decreased workload, more time to complete assignments or tests
Why do we have return to learn protocols?
b/c participation in cognitive tasks that exacerbate symptoms may prolong recovery
Do you need to be symptom free to return to school?
- no but may need modifications
- but do need to be in full academics before return to sports
When would you consider referral to a specialist in concussion?
-persistent symptoms causing prolonged absence from school (more than a couple of weeks)
What is the Return to Play protocol?
- No activity - symptom limited physical and cognitive rest until symptom free; stay at this stage until symptom free for several days (ideally 7-10 days)
- Light aerobic exercise - walking, swimming or stationary cycling; no resistance training
- Sport-specific exercise - skating drills in ice hockey, running drills in soccer, no impact activities
- Noncontact training - progression to more complex training drills (eg. passing drills); may start progressive resistance training
- Full contact practice - following MD clearance, normal training activities
- Return to play - normal
How long should each step in the Return to Play protocol take?
- the first step ideally should be several days (ideal is 7-10 days) before go to step 2
- all other steps should be a minimum of 24 hours
- if any symptoms recurs then rest until it resolves (min 24-48 hrs) before trying again starting with the last step at which they were asymptomatic
What should you do with the athlete with multiple concussions?
- controversial
- may be increased risk for subsequent head injuries and that concussive injuries may be cumulative
- consider retiring from the sport or moving to a less risky position esp if concussion occurs with less force, results in more severe sx, is more likely b/c of playing style or position, occurs in the setting of comorbid learning disability
Does protective equipment (e.g. helmets) prevent concussion?
no but they do protect against other head injuries like fractures, structural damage
What is bodychecking?
-defensive tactic where the defensive player physically extends his body toward the puck carrier while moving in an opposite or parallel direction, a deliberate and forceful move not solely determined by the puck carrier
How is bodychecking taught?
-there is a 4-step skill development program outline by Hockey Canada
When does hockey Canada mandate that bodychecking be introduced?
- peewee (age 11 and 12 yrs) for boys
- bodychecking is not allowed in girls’ or women’ hockey
What is the most common mechanism of injury in hockey?
bodychecking
Is hockey or football more dangerous?
-hockey has more fatality, catastrophic spinal cord and brain injuries than football
What risk factors increase risk of injury in hockey?
- injury increases with increasing skill level
- injuries more likely in games than practices
- goalie is protective
- previous hx of injury or concussion
What are the CPS recommendations regarding bodychecking?
- recommend eliminating it from all levels of recreational/non-elite competitive male hockey
- delay introduction of bodychecking in elite male competitive leagues until players are at least 13 or 14 years old
- use the Hockey Canada 4-stage skill development program
- education of coaches, trainers, schools, etc
- no bodychecking ni womens hockey
What are the risks of sedentary behaviour and increased screen time?
- increased BMI and adiposity
- replaces physical activity
- reduces resting metabolism
- exposes to low nutritive foods through advertising
What factors reduce participation in physical activity?
- inactive role models
- low SES and low education
- cost
- accessibility
- parental time
- dislike sports
- disabled youth
What are the benefits of aerobic physical activity?
-decreases obesity, BP, atherosclerosis, sleep disordered breathing, diabetes, NASH, self-esteem, decreases anxiety and depression
What is the role of exercise-videogames?
-should not replace physical activity but can replace screen time or sedentary activities
What are the benefits of weight-bearing physical activity?
-promotes bone mass acquisition, improved BMD
What are the recommendations for physical activity for infants?
should start in early infancy, floor-based play, tummy time, reaching, crawling
What are the recommendations for screen time in kids
-no screen time
What are the physical activity guidelines for kids age 5-9 yrs?
-screen time 1 hr of physical activity/day; vigorous intensity activities at least 3 days per week, muscle/bone strengthening activities at least 3 days per week
What are the physical activity guidelines for kids 10-12 yrs?
screen time 1 hr of physical activity/day; vigorous intensity activities at least 3 days per week, muscle/bone strengthening activities at least 3 days per week
- pick sports bed on physical maturity
- can start strength training that is supervised (low weight, high reps)
What should MDs do to help improve physical activity?
- write a prescription for it for both aerobic and strength training
- promote
What psychosocial factors contribute to obesity?
- depression/anxiety
- low self-esteem
- bullying
- weight bias (tendency to make unfair judgements based on a person’s weight)
What effect does stress have on obesity?
- stressed kids more prone to emotional eating
- chronic stress –> poor sleep –> fatigue –> no physical activity
- stress impacts the immune system and can have increased illnesses like URTIs
- chronic stress can activate HPA axis and sympathetic nervous system –> insulin resistance, adiposity
What are common stressors for kids that may contribute to obesity?
- parental divorce
- bullying
- physical/mental maltreatment
- abuse
- living in foster care
- living situation where limit-setting and supervision are lacking
What are the parents’ responsibilities when it comes to childhood obesity?
- be good role models
- set limits
- exercise together
- purchase healthy food
- ensure that divorce as un-traumatic as possible
- only kids (without sibs) are at higher risk for obesity
What are some community -level challenges that contribute to obesity?
- cost of nutritious, fresh food is often higher than fast food especially in more remote communities
- fast food and sugary foods are often advertised during kid’s tv
- families with limited income and education are more likely to be overweight
- remote norther communities may have weather that limits physical activity
- unsafe housig limits access to safe facilities
- school programming of physical activity
What is a key technique to use when working with families related to obesity?
motivational interviewing!
- pateitn centered goals which elicit intrinsic motivation for change, useful for pts that are less confident about their ability to change behaviours
- empower parents and patients and give them confidence to make the necessary changes
What are some food specific recommendations you can tell parents regarding childhood obesity?
- avoid casual snacking throughout the day
- avoid using food as a reward or bribe
- discourage food pushing (eating all the food prepared for you)
- avoid exposure to fast foods
- promote eating as a family
- avoid skipping breakfast (is linked to obesity)
