SAFE RETURN TO ACTIVITY (RTA) AFTER MILD TRAUMATIC BRAIN INJURY (MTBI) OBJECTIVES • Review what is a mild Traumatic Brain Injury including causes and symptoms associated with concussion. • Discussion on assessment of concussions and implications • Management of concussions including school accommodations • Role of Physical Therapy to allow your student/athlete to safely return to play. New Minnesota Law CHAPTER 90--S.F.No. 612. •Effective September 1, 2011 •Minnesota State Law requires coaches and/or officials • To remove youth athletes from participating in any youth athletic activity when the youth athlete exhibits signs, symptoms, or behaviors consistent with a concussion; or is suspected of sustaining a concussion. • In order to return to activity the youth must be symptom free & evaluated by a provider trained and experienced in evaluating & managing concussions • Coaches and officials must complete an online training every 3 years • https://www.revisor.mn.gov/laws/?id=90&year=2011&type=0 HISTORY OF THE NEUROTRAUMA CLINIC AT GILLETTE Gillette Children’s Neurotrauma Clinic • Began May 2007 • Children between 0-21 years • Mild to moderate injury • Patient Seen -over 1700 • Mechanisms of Injury • Sports • MVA • Car vs bike • Car vs pedestrian • Falls • Assault • Brain Injuries • Fractures and Bleeds • Spine Injuries • Cervical strains • Fractures • Compression fracture • SCIWORA REVIEW OF MILD TBI’S Traumatic Brain Injury “Defined as a complex pathophysiologic process affecting the brain, induced by traumatic biomechanical forces secondary to direct or indirect forces to the head.” http://www.cdc.gov/ncipc/tbi/Facts_for_Physicians_booklet.pdf Concussion - Definition • Complex process affecting the brain • Induced by traumatic forces • Direct or Indirect • Functional Disturbance rather than Structural Injury • No abnormality on standard structural neuroimaging • Have seen students/athletes after concussion who have had an MRI and because it is normal they are told to return to activity. Acceleration/Deceleration Brain moves forward in skull Frontal lobes strike inside of skull Rebound contre coup injury to the occipital lobe Rotational Injury - - - Brain rotates on axis causing stretching/tearing of axon Stretching and tearing of blood vessels results in hematoma Brain strikes skull causing contusion Causes of TBI Sports-Related Head Injuries: 300,000 per year in U. S. MVA Other Assaults Sports Centers for Disease Control and Prevention 2000 Recreation TBI Deaths: > 500 per year Mild Traumatic Brain Injury - - - Results in a graded set of clinical syndromes that may or may not involve loss of consciousness. Resolution of the clinical and cognitive symptoms typically follows a sequential course Typically associated with grossly normal neuroimaging studies Acute clinical symptoms reflect a functional disturbance rather than structural injury Mild Traumatic Brain Injury Mild TBI can cause functional changes, which are interactive: Cognition (learning, memory and reasoning) Sensation Language (communication, expression, and understanding) Emotion (depression, anxiety, personality changes, aggression, acting out, social inappropriateness) 500 (Giza & Hovda, 2001) Calcium 400 % of normal - K+ 300 Glucose 200 Glutamate 100 50 2 6 0 Cerebral Blood Flow 12 minutes 20 30 6 24 hours 3 6 10 days UCLA Brain Injury Research Center Guidelines for Return to Play • • Guidelines for return to play have been created with this data in mind, avoiding a time period where the brain is more vulnerable to injury due to the energy crisis of the brain Difficult to definitively define the period of vulnerability following TBI, each injury is different with varied effect on the cascade ASSESSMENT OF MILD TBI Assessment • • • Physical exam to rule out bleed, neck injury, spine injury Neurocognitive screening/developmental screening CT scans and MRIs of the head are usually normal and are not necessary unless the patient has increasing symptoms of concern Asking about symptoms Specific yes/no questions about the more subtle symptoms is more effective than asking open ended questions. • “Asymptomatic” is not an easily defined term, though is at the core of proper concussion management • Symptoms may be delayed or recurrent Many athletes may seemingly “normalize” within minutes of an injury, but then have a recurrence and potential worsening minutes to hours later • IMPLICATION: very rare same-day return to play • Signs and Symptoms Somatic: • Headache, pressure, neck pain, n/v, vision changes, balance problems, light or noise sensitivity, “don’t feel right” Cognitive: • Feeling “In a Fog”, difficulty concentrating or remembering, confusion Emotional: • more emotional, sadness Signs and Symptoms • Physical Signs • Loss of Consciousness, Amnesia, motor/sensory deficits • Behavioral Changes • Irritable, nervous • Cognitive Impairment • Slowed reaction times, memory or concentration deficits • Sleep Disturbance • Drowsiness, difficulty falling asleep PCS Assessment/Referral PHQ-9 GAD-7 Pediatric Symptom Checklist Psychotherapy Psychology Psychiatry Pediatric, Adolescent, Adult Medicine Social Work Mood Disruption Headache Log Vestibular Therapy Physical Therapy Relaxation techniques Guided Imagery Integrative Medicine Clinic Neurology Ophthalmology Emotional, Sadness, Nervousness, Irritability ImPACT Testing Pediatric Symptom Checklist Somatic Symptoms Cognitive Symptoms Vanderbilt ADHD Scale Migraine, Driving Evaluation Attention problems, Headaches, Memory dysfunction, Speech Therapy Visual problems “Fogginess”, Dizziness/balance disturbance Occupational Therapy Fatigue, Noise/Light sensitivity Cognitive Slowing Psychology Nausea Neck Pain/Spine Pain Psychiatry Sleep Alterations Neuropsychology Difficulty falling asleep Sleeping less than usual Sleep Log Sleep Specialist Neuropsychological Testing • Objective evaluation of function • Baseline testing may be helpful • Allows comparison of baseline to post-injury tests • If baseline testing is not available, compare to agematched controls and a percentile generated CDC Heads Up – Brain Injury in your Practice Facts for Physicians booklet Acute Concussion Evaluation (ACE) form ACE Care Plan Work version School version Concussion in Sports palm card MANAGEMENT OF MILD TBI’S Goals of post injury management • Prevent against Second Impact Syndrome • Prevent against cumulative effects of injury • Prevent presence of Post-Concussion Syndrome • Determination of asymptomatic status essential for reducing repetitive and chronic morbidity of injury • Post injury: cellular metabolism is over worked, thus the cells are more vulnerable to further insults and injuries. Management • • • Physical rest “Cognitive” rest • Child needs to limit exertion with activities of daily living and limit scholastic activity while symptomatic • Repeated injury or overstimulation during the energy crisis of acute brain injury could lead to cell death Pharmacology • Management of specific symptoms Giza, Hovda. The Neurometabolic Cascade of Concussion. J Athl Train. Vol 36, p 228-235, 2001. What is Cognitive Rest? • Cognitive rest may also be called “brain rest” • After a MTBI, we need to limit the activities that use “brain energy” so that the brain can function on the limited amount of energy it is creating. • To help the brain heal and recover, some cognitive activities need to be limited temporarily. What is Cognitive Rest? • Some symptoms may worsen when engaging in cognitive and physical activities. This is the body’s way of indicating it is not able to make the amount the energy being demanded, activity should be stopped to allow body to rest. What can be done on cognitive rest? • OK to watch TV, watch movies, and listen to music. The volume should be low. • Go to school and do homework; however if school and school work increases symptoms you may need accommodations at school, shortened school days or to stay home. What is not allowed while on cognitive rest? • • • • • • • • No computer activities No video games No recreational reading No board games No card games No text messaging No computer activities No practicing musical instruments What is physical rest? • Physical rest is limiting the amount of energy spent in physical activity to allow the brain to use that energy to heal. What can be done on physical rest? • Walk with feet on the ground at a casual pace. • Attend to school (no phy ed, gym class or recess). What is not allowed while on physical rest? • • • • • • • • • No sports No games No practices No gym/recess/exercise No strenuous activity No physical labor/work No amusement park rides No biking/skating/sledding/skiing No jumping School Accommodations - Approve dismissal for medical appointments related to this injury Reduced homework load. Limit to two hours maximum for all subjects per night. Limit computer time and reading requirements as needed Early dismissal/late arrival as needed Extended time for testing, homework etc School Accommodations • • • • • Eliminate non-essential work Rest period in Health Office during day as needed Wear hat or sunglasses for light sensitivity Preprinted class notes Utilize tools that address learning style: audio/video recorders, computers, etc How can your student receive accommodations at school? • First identify the contact person at your school: advisor, dean, principal. • Alert the school and teachers of the injury as soon as possible. • Arrange a meeting with the school to discuss school accommodations, bring in medical documentation. Symptom Treatment • REST!... the only known effective treatment for a concussion • Encourage frequent breaks from studying • Encourage good hydration and regular meals to avoid dehydration and hypoglycemicrelated headaches Student Athlete Management • COGNITIVE REST • If symptoms recur with cognitive activity, time off school may be needed • Involve teacher, school nurse, principal, coach PCS Management Antidepressants Anxiolytics Psychotherapy Non-Pharm Headache Management OTC: NSAIDs Triptans Beta Blockers CCB Antiepileptics Antidepressants Flexeril Valium Amitriptyline Mood Disruption Emotional, Sadness, Nervousness, Irritability Somatic Symptoms Migraine, Cognitive Symptoms Headaches, Attention problems, Visual problems Memory dysfunction, Dizziness/balance “Fogginess”, disturbance Fatigue, Noise/Light sensitivity Cognitive Slowing Nausea Neck Pain/Spine Pain Amantadine* (off label) Neurostimulants* (off label) Sleep Alterations Difficulty falling asleep Sleeping less than usual Behavioral: Sleep hygiene education, relaxation therapies, sleep schedule Pharmacologic: melatonin, amitriptyline, trazadone, short-term use of nonbenzodiazepines Pediatric Athletes (<18) American Academy of Pediatrics (AAP) recommends “conservative” management: • NO return to play on same day • Seriously, NO return to play on same day • When in Doubt, Sit them OUT! High school athletes’ and their recovery from concussion Collins M, et al. Neurosurg 2006 Return to Play • Normal imaging • Normal physical exam • Normal cognitive screen • Symptom free - Medication free (without activity) Role of Physical Therapy for Return to Activity • Determine readiness to return • Balance and vestibular assessments • Stages for return to activity DETERMINING READINESS TO RETURN TO ACTIVITY Readiness for Return to Activity • No adolescent with a concussion should continue to play or return to a game after sustaining a concussion. • Immediate Evaluation and Exam after a Concussion • An individual sustaining a concussion should cease doing any activity that causes the symptoms of a concussion to increase (e.g. headaches, dizziness, nausea, etc.). Readiness for Return to Activity • If patients develop increased symptoms while doing a specific activity, that activity should be discontinued. • Continuing activities, or exercise that increases symptoms, can delay the recovery from the concussion. What are the risks of returning to activity before an injury is healed? • Symptoms may last longer and become more intense. • New symptoms may occur. • Risk of repeat injury and risk of Second Impact Syndrome. Explain Risks of Premature RTP before full recovery • 2nd impact syndrome • Death • Higher risk in young athletes • 2nd concussion, more severe • Prolonged symptoms Second Impact Syndrome • In September of 2008, Jaquan Waller, 16, suffered a concussion during football practice at J.H. Rose High School in Greenville, N.C. • A certified athletic trainer educated in concussion management wasn't onsite, and the school's first responder who examined Waller cleared him to play in a game two days later. • During that game, Waller was tackled. Moments later, he collapsed on the sidelines. • He died the next day. Second Impact Syndrome • A medical examiner determined Waller died from what is called second-impact syndrome, noting that "neither impact would have been sufficient to cause death in the absence of the other impact." • Read more: http://www.time.com/time/magazine/article/0,9171,1873131,00.html#ixzz1SegF8gRE Discussion/Quiz WHEN ARE PATIENTS REFERRED FOR RETURN TO ACTIVITY? • No athletes should return to contact competitive sports until they are symptom free, both at rest and with exercise and have normal neuro-cognitive testing. • When they no longer have headaches or other concussion symptoms athletes can begin the concussion graduated return-toplay exercise program that was recommended at the Prague Concussion Conference. Initial Evaluation • Monitoring heart rate via use of a Polar Heart Rate Monitor. • A strap with the monitor is placed around child’s upper body under chest and a watch is used to read their heart rate. • Scapular/Cervical Screen • Look at scapular (shoulder blade) alignment, upper extremity antigravity movement and cervical Range Of Motion: looking for symmetry & onset of cervical pain & substitutions • Strength screen for cervical musculature: • It is very common (especially for girls and women) to overuse sternocleidomastoid (SCM) as compared to intrinsic musculature of the neck • Some evidence that cervical weakness contributes (or is at least correlated with) repeat concussion in girls • Look at chin tuck against gravity: any substitution with SCM? • Check general isometric strength screen for cervical spine: looking for cervical pain BALANCE TESTS BESS • Balance Error Scoring System (BESS) • Can be used by athletic trainers immediately following concussion on the sidelines • Utilized in the clinic as well to assess higher level balance BESS • 6 testing positions • All positions are preformed with eyes closed • Each position is held for 20 seconds • Count number of errors that occur BESS Testing Positions Errors noted during the BESS • Hands lifted off iliac • Remaining out of crest • Opening eyes • Step, stumble, fall • Moving hip into more than 30 degrees of flexion or abduction • Lifting forefoot or heel off floor testing position for more than 5 seconds • **The maximum total errors for 1 testing position is 10 errors** BESS • Insert Bess videos Functional Gait Analysis • Video VESTIBULAR EVALUATION Vestibular Assessment • Patients frequently complain of headache, dizziness, and vision problems following concussion • Oculomotor and Vestibular systems are assessed on all patients at initial evaluation What are the goggles? • Infrared video goggles which help us to view eye movements • Allows for observation and video recording of eye movements in both light and in the dark with the vision occluded • Simultaneously records audio (important for later interpretation) Real Eyes xDVR Who is appropriate for the goggles? • Patients from neurotrauma clinic • Patients complaining of • Headache • Dizziness • Nausea • Difficulty with reading/schoolwork • Referred for “balance and vestibular testing only” What tests are done with the goggles on in the light?

Case Study #1 Vestibular Case Study #2 Return to Activity Conclusions • It is our responsibility to know what a concussion looks like. • • • Concussions for young athletes are increasing and underreported. DO NOT RETURN ANY PLAYER TO PLAY THE SAME DAY A SUSPECTED CONCUSSION OCCURS. Symptoms may not be reported by the athlete for > 15’ so be very cautious if you suspect a concussion. Conclusions (cont.) • Young athletes who have a concussion need to have complete REST until symptom free. • • The most common symptoms associated with concussions are headaches, dizziness, “fogginess”, concentration/memory problems Once symptom free then slowly return to activity and monitor for any change in symptoms ACCESS TO NT CLINIC Gillette Children’s Neurotrauma Clinic - - What does an appointment entail?
