Concussion Management
Significant changes towards
more individualized, specific
management.
Increased knowledge has
lead to State and Local
legislation.

Concussion Management
‘The cornerstone of concussion management is
physical and cognitive rest until the acute symptoms
resolve and then a graded program of exertion prior
to medical clearance and return to play.’
No play day of injury
No Play if any symptoms
85-90% resolve by 10 days
Consensus Statement on Concussion in Sport—the 4th
International Conference on Concussion in Sport. Held in Zurich,
November 2012
![Page 4: Concussion Management - c.ymcdn.com · Concussion Management ‘The cornerstone of concussion management is physical and cognitive rest until the acute symptoms resolve and then a](https://reader031.vdocuments.us/reader031/viewer/2022012918/5c83290109d3f2e31c8d05cf/html5/thumbnails/4.jpg)
Post Concussion Management Timeframe
Concussions are:
Evolving, multifactorial, and individual.
No longer graded
Acute: 1-7 days
Rest; start easy re-introduction
Sub acute: 5 – 14 days
Gradually increase activity
Protection
Chronic: 10 - 21 days and longer
Consider other therapies: scrutinize circumstances, Rx;
Physical / Ocular / Counseling therapy.

Vestibular: Balance / Coordination
Concussions can affect the afferent
(proprioception) or integration (brain
stem) signals, reducing balance
Balance testing is valuable for Dx and
management.
Program:
balance exercises, both with eyes open and
closed (utilizing somatosensory and
vestibular inputs)
Progressive difficulty
• Single leg, unstable surface, surfing,
jump/twist/catch, etc.
![Page 14: Concussion Management - c.ymcdn.com · Concussion Management ‘The cornerstone of concussion management is physical and cognitive rest until the acute symptoms resolve and then a](https://reader031.vdocuments.us/reader031/viewer/2022012918/5c83290109d3f2e31c8d05cf/html5/thumbnails/14.jpg)
Vestibular: ‘Dizziness’
Diagnosis malady, then treat specifically
Light headed or Vertigo?
Light headedness
Cervical muscle tightness
Metabolic, hypoglycemia, etc.
Anxiety
Vertigo
Room is spinning
Uneasy or queasy feeling, like on a boat
Treated differently
![Page 15: Concussion Management - c.ymcdn.com · Concussion Management ‘The cornerstone of concussion management is physical and cognitive rest until the acute symptoms resolve and then a](https://reader031.vdocuments.us/reader031/viewer/2022012918/5c83290109d3f2e31c8d05cf/html5/thumbnails/15.jpg)
Vestibular-Ocular Reflex (VOR)
Activation of the vestibular
system causes compensatory
eye movements
The ability for the eyes to
maintain vision on an object
with head movement
Eg., running down street while
reading a sign.
VOR keeps image on Fovea of eye
![Page 16: Concussion Management - c.ymcdn.com · Concussion Management ‘The cornerstone of concussion management is physical and cognitive rest until the acute symptoms resolve and then a](https://reader031.vdocuments.us/reader031/viewer/2022012918/5c83290109d3f2e31c8d05cf/html5/thumbnails/16.jpg)
Vestibular issues Symptoms
Dizziness, fogginess, nausea, anxiety, overwhelmed,
can’t multi-task, off balance.
Dx with VOMS (Vestibular Oculomotor Screen)
Sensitive for dx and monitoring concussion
Pursuit, Saccades, Convergence, VOR (Vestibulo-
Ocular reflex)
Goal is to restore brain’s ability to sense and
respond to motion; (Reduce dizziness, help balance)
![Page 17: Concussion Management - c.ymcdn.com · Concussion Management ‘The cornerstone of concussion management is physical and cognitive rest until the acute symptoms resolve and then a](https://reader031.vdocuments.us/reader031/viewer/2022012918/5c83290109d3f2e31c8d05cf/html5/thumbnails/17.jpg)
Canalith repositioning
BPPV
Can occur with concussions.
Positional vertigo
Dx: Dix-Hallpike maneuver
Tx: Epley maneuver

Concussion and Vision
46% concussed pts have visual problems (Vision Dx…, Clinical Pediatrics, 2015; The neuro-opth of head trauma,
Lancet Neuro 2014)
Photophobia: dysfunctional pupillary response
Blurred vision: dysfunctional accommodation
Diplopia: dysfunctional binocularity
Loss of place while reading: dysfcn. ocular motility
(Carl Hillier, OD FCOVD)
![Page 19: Concussion Management - c.ymcdn.com · Concussion Management ‘The cornerstone of concussion management is physical and cognitive rest until the acute symptoms resolve and then a](https://reader031.vdocuments.us/reader031/viewer/2022012918/5c83290109d3f2e31c8d05cf/html5/thumbnails/19.jpg)
Ocular motor
Coordinate eyes for vision during head motions
Testing:
Saccadic movements, smooth pursuits,
convergence deficits, or symptoms during exam
Rehab
Performing similar motions, allowing brain to re-
build these mechanisms, allowing accurate vision
with motion.
May use prisms, lenses, etc.
Dynamic exertion training:
Patient focuses on one object while running
![Page 20: Concussion Management - c.ymcdn.com · Concussion Management ‘The cornerstone of concussion management is physical and cognitive rest until the acute symptoms resolve and then a](https://reader031.vdocuments.us/reader031/viewer/2022012918/5c83290109d3f2e31c8d05cf/html5/thumbnails/20.jpg)
Neuro-Optometric Rehab
Vision Rehab. goals:
Recapture accommodative (CN 3) and
binocular (CN 3, 4, 6) skill and endurance
Recapture saccadic skill and endurance
Recapture pupillary response (CN 3) to
reduce photophobia.
Using specific procedures and
instrumentation (stereo-scopes, plus
and minus lenses, prisms)

Essentials for RTP (CIF)
No physical activity for at least 2 days after athlete seen by Dr.
Dr. must clear athlete before RTP protocol starts
Return to sport cannot be sooner than 7 days AFTER seen by Dr
If the concussion injury does not resolve in 7-10 days, treatment
should also consider:
Further Reduction of aggravating factors, mental and physical
Consider Rehab for balance, oculomotor, CT strain, etc.
Consider medications as appropriate
![Page 28: Concussion Management - c.ymcdn.com · Concussion Management ‘The cornerstone of concussion management is physical and cognitive rest until the acute symptoms resolve and then a](https://reader031.vdocuments.us/reader031/viewer/2022012918/5c83290109d3f2e31c8d05cf/html5/thumbnails/28.jpg)
Keys to RTP
Athlete needs to see a Physician (MD/DO) asap after injury to
start the clock for recovery
The athlete must do a supervised, graduated RTP protocol to
return to sport
The athlete needs written notification:
to begin protocol, and
for release to full sport (stage 3) by a licensed physician (MD/DO).
If concussion is not improving, recommend seeing a physician
experienced in the field to facilitate safe recovery
Baseline testing is recommended
![Page 29: Concussion Management - c.ymcdn.com · Concussion Management ‘The cornerstone of concussion management is physical and cognitive rest until the acute symptoms resolve and then a](https://reader031.vdocuments.us/reader031/viewer/2022012918/5c83290109d3f2e31c8d05cf/html5/thumbnails/29.jpg)
Clinical case
Athlete injured on Friday night
with a mild concussion (Day 0).
Seen Monday by physician
(Day 3). If Now asymptomatic,
Begin Stage I: no activity for at
least 2 full symptom-free days
![Page 30: Concussion Management - c.ymcdn.com · Concussion Management ‘The cornerstone of concussion management is physical and cognitive rest until the acute symptoms resolve and then a](https://reader031.vdocuments.us/reader031/viewer/2022012918/5c83290109d3f2e31c8d05cf/html5/thumbnails/30.jpg)
Case
Begin Stage II-A : light aerobic activity. Must
be performed under direct supervision by designated individual (Day 5).
Begin Stage II-B : moderate activity (Day 6).
Begin Stage II-C : strenuous activity (Day 7).
Begin Stage II-D : non-contact training (Day 8)

Case
Stage III : Limited contact practice (Day 9).
Stage III(second level): Full contact (Day 10).
Must complete at least one contact practice
before return to competition. Highly
recommended divided into 2 contact practices.

Concussion Management
Summary
Significant change in management of concussions:
from grading/cookie cutter approach to:
individual care with focus on manifestations.
Relative rest for brain and body; allow healing without
re-incident; gradual progression as tolerates.
Prioritize treatment to specific manifestations
Utilize Rx; Vestibular/Ocular/Physical/and
Psychological therapy as needed
Guidelines per state / organizations;
RTP and RTL protocols
