Why are we here today?
• Data shows that an overwhelming majority of youth
sports concussions occur in practices or games
where no athletic trainer or physician is present
• We want to educate coaches, parents and school
officials about basic concussion diagnosis and
treatment so that these important injuries are
recognized and more severe injuries are prevented
But we are NOT here to…
• Get rid of football (or any other sport)
• Frighten everyone that all sports are
dangerous and cause long term brain damage
• Turn everyone into a concussion expert or
brain surgeon in 2 hours
Program objectives
• Understand what is a concussion and what
are common signs and symptoms
• Discuss initial treatment and transport
• Outline how we return someone to play after
injury
• Review baseline testing
• Describe current evidence about long term
outcomes
• Update prevention strategies

Is this a concussion?
• 11 yo was swinging on a tree limb, fell 5-6’
and hit the back of his head on the ground
• Loses consciousness for one min according to
other kids
• Then has headaches and blurry vision
• Vomits twice
Is this a concussion?
• Seen at the Emergency Room - “normal
exam”, CT Scan negative
• Goes back to school with headaches needing
Ibuprofen
• Headaches get worse with physical activity
(including practicing with his travel baseball
team)

What is a Concussion?
• Lots of terms
– Ding, bell rung, shaking off the
cobwebs, closed head injury,
mild traumatic brain injury
(mTBI)
• “A trauma induced
alteration in mental status
that may or may not involve
loss of consciousness”
—AAN 1997
• Headache plus…
• Transient Neurological
Phenomenon
Definition of Concussion
1. Caused either by a direct blow to the head, face, neck or
elsewhere on the body with a resultant force transmitted to
the brain.
2. Typically results in the rapid onset of short-lived changes in
neurological function that resolves spontaneously.
3. May result in structural brain changes, but the symptoms
largely reflect a functional disturbance rather than a structural
injury.
4. Usually follows a progressive course of improvement
5. Imaging studies (brain CT/MRI) are usually normal.
Signs and Symptoms of Concussion
Signs
•
•
•
•
•
•
•
•

•
Appears dazed or stunned
Confused about assignment
Forgets plays
Is unsure of game, score, or
opponent
Moves clumsily
Answers questions slowly
Loses consciousness
Shows behavior or personality
change

•
Headache
Nausea
Balance problems or dizziness
Double vision
Sensitivity to light or noise
Feeling sluggish
Feeling “foggy”
Concentration or memory
problems
• Change in sleep pattern (appears
later)
• Feeling fatigued
Common symptoms of concussion from a series
of injured high school athletes
•
Three most common symptoms:
1. Headaches (55%)
2. Dizziness (42%)
3. Blurred vision (16%)
•
•
46% experienced either cognitive or memory
problems
9% had loss of consciousness (“knocked
out”)
Do you have to be “knocked out”
to have a concussion?
• NO!!!!!
• In fact, only a SMALL number of concussed athletes were
“knocked out”
• Many studies have now shown that amnesia (inability to
remember) is a much more common sign of concussion and
ALWAYS indicates that a brain injury has occurred
What are the “Grades” of a
concussion?
• In the past concussions were often classified
into grade 1, 2, or 3 based on the severity and
duration of symptoms at the time of injury
• Many research studies have showed that
these grading scales were useless in predicting
the severity of injury or how long to recover
• Grading scales are no longer used
If you have a history of a previous
concussion are you more likely to have a
longer duration of symptoms?
• Available research says “yes”
Does having a concussion increase your
chances for a future concussion?
• Some research says “yes”
• 92% of the in-season repeat concussions occurred
within 7-10 days of first
Epidemiology of Concussion
• 1.5-3.8 million reported cases
of brain injury per year in the US
(CDC)
• 20% (300,000-760,000) are
sports-related
• 53,000 deaths each year
• 70-90,000 permanently disabled
• Highest sports incidence: ages 1524
• Cost estimated at > $60 billion
annually
HS RIO™ Injury

Objectives:
1. Overview of the brain
2. What happens in the brain during a concussion--immediate, short, and long-term effects
3. How long it takes for the brain to recover from a concussion
4. Potential long-term effects
a. Post-Concussion Syndrome (PCS)
b. Chronic Traumatic Encephalopathy (CTE)
Average Adult Human Brain
Weight = 1350 g (~3 lbs.)
Width = 140 mm (5.6”)
Length = 167 mm (6.68”)
Height = 93 mm
(3.72”)
Brain = 2% of Total Body Weight
Average Adolescent Brain is Smaller
We can think of the brain as a computer
it is composed of hardware (structure)
and software (function)
Hardware (Structure) = brain tissue
Software (Function) = Electrical and chemical processes ongoing
within the brain tissue that allows us to sense, think, feel, and act
Sports related concussions rarely cause a hardware problem (structural
injury)
When structural injuries do occur, they are usually due to tearing of a
blood vessel (resulting in an epidural or subdural hematoma) or in
some cases, tearing of nerve cells (traumatic axonal injury)
However, these structural injuries are extremely rare in sports.
This is why the structural CT or MRI scan is normal 99+% of the time
after a sports concussion
Sports concussion usually causes a disruption in brain function
(software problem), which leads to the signs and symptoms described
previously
The disruption in brain function has
been termed “the chemical cascade”
The Chemical Cascade of Concussion
Blood flow to the brain is reduced immediately after a concussion
The brain operates on 2 kinds of fuel: glucose and oxygen
The brain gets glucose and oxygen from the blood supply
But because the brain is getting less blood flow after a concussion,
the brain is not getting the typical amount of fuel (energy)
The difference between the energy the brain is getting and what the
brain needs to operate fully results in an energy crisis and the
symptoms
PET Scans in Head Injury (Glucose)

University of Pittsburgh Medical Center
Drs. Victoria Morgan and Megan Strother, Vanderbilt
The short term effects of concussion are age- and
possibly gender dependent
Younger athletes take longer to recover than older athletes, probably
because the brain is not fully developed physically until about age 23
Many studies have indicated that females may take longer to recover
than males, although a recent VSCC study did not support this
Other factors affecting the duration and intensity of symptoms after a
concussion can include concussion history and co-existing disorders
such as ADHD, learning disabilities, sleep disorders, psychiatric illness,
and migraine headaches
To get back to the computer analogy, when we have a software
problem, we usually shut down the computer and re-boot it.
After a concussion the brain typically repairs (re-boots) itself.
But how long does it take?
First, there is no FDA-approved medication for concussion, although
many drugs are used to treat the symptoms of concussion
In general and on average, the short term effects of concussion
resolve within:
7 days for professional athletes
7-10 days for collegiate athletes
7-14 days for high school athletes
7-21 days for younger athletes
>90% of athletes with sport-related concussions
recover within a month
Second Impact Syndrome (SIS)
However, if an athlete does not recover fully from an initial concussion
and sustains another concussion before the first has cleared
completely, then he may be at risk for Second Impact Syndrome (SIS)
SIS is a very rare condition and typically occurs in teen aged males
SIS has never been reported in females or in professional athletes
SIS occurs when an athlete sustains an initial concussion that is
unrecognized, not reported, or has not fully healed,
SIS occurs when an athlete sustains an initial concussion that is
unrecognized, not reported, or has not fully healed
The brain remains in a vulnerable state from the initial concussion
(energy crisis)
The athlete then sustains a second concussion which causes additional
chemical changes in the brain that lead to severe brain swelling
The brain is encased in a hard skull and can only expand within certain
limits
SIS usually results in permanent disability or death

Sports Concussion: Long Term Effects
Post-Concussion Syndrome (PCS)
Chronic Traumatic Encephalopathy (CTE)
Post-Concussion Syndrome (PCS)
The term was first used by an article by Strauss and Savitsky in 1934
Multiple definitions abound and vary somewhat, but all involve a
constellation of symptoms after a blow to the head
Symptoms common to most definitions include a persistence of the
initial concussion symptoms, including headaches, dizziness, fatigue,
irritability, forgetfulness, poor concentration, blurred vision, sensitivity
to light and noise, frustration, sleep disturbance, difficulty thinking,
nausea, depression, increased emotionality
The diagnosis is made anywhere from 6 weeks to 3 months post-injury
Most of the scientific research on PCS has been done on civilians, and
more recently, on military personnel experiencing blast injuries
Studies of PCS in athletes are now being conducted
In general, less than 10% of athletes are diagnosed with PCS
Most of these athletes recover within 6-12 months, although there is a
small group that remains symptomatic longer
PCS typically involves multiple factors and usually requires
a multi-disciplinary treatment approach
Chronic Traumatic Encephalopathy (CTE)
• Punch-Drunk Syndrome (Martland, 1928, JAMA)
• Dementia Pugilistica (Millspaugh, 1937, US Navy Medical Bulletin)
• Psychopathic deterioration of pugilists (Courville, 1962, Bulletin Los
Angeles Neurological Society)
• Chronic traumatic encephalopathy (Miller, 1966, Proceedings of The
Royal Society of Medicine)
• Chronic traumatic brain injury
(Jordan et al., 1997, JAMA)
CTE has receive a resurgence of interest due to several professional
athletes (especially football players) being diagnosed with CTE after
death
The current definitions of CTE are somewhat different but common
elements include the appearance of a tau protein in brain tissue, found
on autopsy
Mood, behavioral, and cognitive changes occur prior
to death
CTE is an evolving area of study and merits close scientific
investigation with well designed, well controlled research
CTE, like most neurodegenerative disorders, is a multifaceted brain disease that involves a variety of genetic,
athletic exposure, and lifestyle factors
“…a cause and effect relationship has not yet been
demonstrated between CTE and concussions or exposure
to contact sports.”

Concussion Baseline Testing
Tim Lee, MHA, MS, ATC
Coordinator, VSCC
What is baseline testing?
• Baseline testing is a
series of standardized
exams used to assess an
athlete’s balance, brain
function, and symptoms.
• Results of the baseline
test can be used to
compare to a follow-up
exam if the athlete has a
suspected concussion
What is included in VSCC baseline testing?

Time
When should an athlete be
baseline tested?
• Pre-season, before
contact
• Currently, ages 12
years old up.
How often should an athlete be baseline tested?
• Every 2 years
• Unless an athlete
has suffered a
concussion, has a
new diagnosis of
ADD/ADHD, or
learning disability
• mBESS and symptoms
checklists should be
performed yearly.
Who should administer the baseline test?
• A trained healthcare
professional (MD, DO,
ATC, PhD, PT)
• The testing
environment should
be quiet and free
from distractions
• Computer-based
testing should not be
performed at home or
anywhere without
supervision
Who should interpret the test results?
• A healthcare
professional
trained in
concussion
management
What are we
looking for in
these tests
after a
concussion?
• We are expecting that the
athlete’s test scores on all
the measures will have
returned to the baseline
values.
• This would indicate that the
athlete has most likely
recovered from the
concussion.

Outline
• What is a comprehensive concussion
plan and who should have one?
• How do we safely return someone to play
after a concussion?
• What does “return to learn” mean?
• When should ImPACT testing be
repeated?
• What to do when symptoms continue for
more than a few days?
Comprehensive
Concussion Plan
Comprehensive Concussion Plan
• Defines goals, key personnel, groups to
be served
• Discusses prevention and equipment
• Details baseline evaluations
• Delineates immediate management
• Identifies “red flags” for urgent medical
evaluation or transfer to ER
• Determines follow up care
• Return to Play (RTP) protocol
Concussion Plan
• Not a “rigid recipe” but rather a roadmap
to a common destination
– Allows for rest stops and sightseeing –
individual flexibility!
• But it is not OK to just “wing it”!
– Increases liability
– Decreases credibility
• No need to reinvent the wheel
Return to Play
“When can my boy get back out
there where he belongs?”
Return to Play - goals
• Return athlete to play as soon as possible
after brain injury has healed
• Emphasize actions and treatments that
enhance and promote recovery
• Avoid actions and treatments that hinder
recovery
• Return to play really begins as soon as
concussion is diagnosed
Same Day Return to Play
• Once any athlete at any age has been
diagnosed with any concussion they are
done for that day
–
–
–
–
No exceptions!
No such thing as a ding!
No grading scale
Be aware that some injuries may evolve over
time and symptoms may be delayed
– Serial evaluations are helpful
Acute treatment
• First 48 hrs
– Physical AND cognitive rest
– Avoid tasks which increase symptoms
• “overstimulation” of brain
• Simplify brain inputs
– “live like the Andy Griffith show”
– Some symptoms may evolve
• especially headache, concentration
Acute treatment
• First 48 hrs
– Encourage sleep
• Don’t need the every hour wakeup!
• “excessive” sleep probably OK
– School OK depending on tolerance
• Low threshold for absence – generally avoid until no
symptoms for 24 hours
– Meds – Tylenol usually adequate
– Red flags – immediate referral for medical eval
• Previous talk
– ER physician CANNOT CLEAR FOR RETURN
TO PLAY!!!
After 48 hours
• Reassess by practitioner trained in
concussion management
• NO role for ImPACT testing in this stage
– May increase symptoms
– Practice effect
– Does not change plan
• Once asymptomatic for 24 hrs can return
to class
– If symptoms in class may need to modify
schedule
Return to play stages
Return to Play progression
• After a concussion, we want to
GRADUALLY increase exertion in a
progressive manner to see if the athlete
has symtoms
– Athletes may have no symptoms at rest but
symptoms may emerge with exertion
– This means the brain has not fully healed from
the concussion
Return to Play progression
• Steps should be spelled out in your
concussion plan
• Should be overseen by someone trained
in concussion management
– Athletic trainer
– Physical therapist
– Physician (MD/DO), nurse practitioner (NP) or
physician’s assistant (PA) experienced in
athletic medicine and concussion care
Return to Play - stages
•
•
•
•
•
Phase “0” – cognitive exertion
Phase 1 – aerobic exertion
Phase 2 – functional testing progression
Phase 3 – sport specific exertion
Phase 4 – limited drills and non-contact
practice
• Phase 5 – full participation without
restrictions
• For most athletes 24 hour minimum per
phase
From the
Vanderbilt University Athletics
Mild Traumatic Brain Injury (mTBI)/Concussion Evaluation Guidelines (2012)
RTP Phase 0 – Cognitive Exertion
• No physical exertion until completion of
full school day and all academic work
with NO symptoms
• If no school – find other cognitive tasks
– Reading for comprehension
Courtesy of Tracy Campbell, ATC
• The athlete must be able to
“Return to Learn” BEFORE they
can begin the “Return to Play”
pathway
RTP Phase 1 – Aerobic Exertion
• Begin exertion to raise HR under
monitored conditions
• Example: Functional exertion test
– Bike 20 minutes @ 70 percent of predicted maximum heart
rate(PMHR)
– Rest for 15 minutes
– Monitor symptoms
– Incremental Treadmill Test 20 minutes
From the
Vanderbilt University Athletics
Mild Traumatic Brain Injury (mTBI)/Concussion Evaluation Guidelines (2012)
RTP Phase 2 – Functional Testing
Progression
• More complex movements at higher pace, but
generally in a single plane
• Examples:
–
–
–
–
–
–
–
Scissor step/quick step
Jogs
lateral shuffle
Backpedal
Sit-ups
Push-ups
Sprints
From the
Vanderbilt University Athletics
Mild Traumatic Brain Injury (mTBI)/Concussion Evaluation Guidelines (2012)
RTP Phase 3 – Sport Specific Exertion
• Initial
– Moderate aerobic exercises specific to sport
– Duration approximately 10- 15 minutes with 5 minutes
rest post session
• Intermediate
– Progressively difficult aerobic exercises specific to sport
– Duration approximately 10- 15 minutes with 5 minutes
rest post session
–
• Advanced
– Demanding aerobic exercises specific to sport
– Duration approximately 10- 15 minutes with 5 minutes
rest post session

•
•
•
•
•

Vanderbilt University Athletics
Mild Traumatic Brain Injury (mTBI)/Concussion Evaluation Guidelines (2012)
RTP Phase 4 – Return to Limited Drills and
Non-contact Practice
• Non-contact training drills dependent upon sport
• Athlete can practice with team but no contact
• Consult team physician for full clearance
From the
Vanderbilt University Athletics
Mild Traumatic Brain Injury (mTBI)/Concussion Evaluation Guidelines (2012)
RTP Phase 5 – Return to Full Participation
without restrictions
• Full participation without restriction
• For collision sports will usually practice
full speed with contact before game action
(if available)
From the
Vanderbilt University Athletics
Mild Traumatic Brain Injury (mTBI)/Concussion Evaluation Guidelines (2012)
RTP – How NOT to do it
• “We didn’t let him practice all week and
he feels good today (Thursday) so we’re
gonna let him play Friday night.”
• “He rested for 3 days then I put him on
the bike today for 15 minutes and he did
fine so I let him go to practice today”
• “She felt bad all weekend but today she
just has a slight headache and seemed ok
in warmups so I let her go.”
RTP – “Pearls”
• If athlete has symptoms during one stage,
then should rest for 24 hours and go back
to previous stage
• Careful observation during and after final
stage / first game back
– EDUCATION of athlete!
• An extra few days in the RTP protocol
might save your athlete a month, a
season, or even a whole school year!
When should ImPACT testing be
repeated?
• Purpose of repeat test is to make sure
that brain function has returned to
baseline
– Especially if athlete is not being truthful about
their symptoms!
• NO reason to repeat test if athlete is still
having symptoms
When should ImPACT testing be
repeated?
• Can do test either prior to starting RTP
protocol or at any stage as long as athlete
is still without symptoms
• ImPACT test alone cannot “clear” an
athlete to return – it is a PART of an
overall assessment to be used by a
trained provider
Prolonged Recovery
JAE S. LEE / THE TENNESSEAN
Pathways to Recovery
• 2 general “pathways” to recovery have
been identified
– Standard (80 – 90%)
• all symptoms resolve in 7 to14 days
– Prolonged (10 – 20%)
• Symptoms for > 30 days
• This distinction appears over time and
initial treatment principles are same
Prolonged recovery
• Definition: more than 30 days of
symptoms
• Symptoms may not be specific to
concussion
– Require other management strategies
– Advanced imaging
– Formal neuropsych testing
Prolonged recovery
• All of these patients will benefit from
evaluation by a concussion specialist and
a multi-disciplinary approach
• Advanced interventions
– Treat sleep / mood problems
– Headache prophylaxis and treatment
– Vestibular assessment and rehab for balance
issues
– Cognitive evaluation and therapy for
persistent school problems

Prolonged recovery – what to avoid
• Avoid social and personal isolation for
prolonged periods of time
–
–
–
–
No school
No sport
No social activities
No life!
Summary
• Everyone needs a concussion plan
– You need a trained provider to evaluate athletes who
sustain a concussion and to supervise their return to
play
• No RTP same day – no exceptions
• Physical and cognitive rest in first 48 hrs
• No physical exertion until asymptomatic
with brain exertion
• Stepwise RTP – be systematic
• Athletes with prolonged recovery are
unique and need specialist assessment

Summary of Helmet Benefits in Sports
Vanderbilt Sports Medicine
Headgear Fitting
• Important across sports
– A well maintained, properly fitted helmet required
to provide advertised level of protection to athlete
• Serious head injury (not concussion)
– Frequently inspect equipment for wear and tear
including cracks, defects and loss of proper fit
• Hands-on demonstration
