Lecture 20 Head & Spine injuries -can involve serious condition -which includes paralysis Concussion: complex pathophysiological process affecting the brain, extended by traumatic biomechanical forces Causes: direct/indirect force to head, face, neck, etc. Symptoms: immediate/delayed **It is not always loss of consciousness –it may/may not Acute signs/symptoms: headache, confusion, imbalance, visual problems, loss of memory, behaviour change -may cause multiple adverse effect SCAT-sport concussion assessment is used for couches -use of the memory test -seeing how many words or numbers can be remembered -use of reverse numbering can be very helpful for evaluation of the concussion -other test like today’s date is not good Simple concussion: no loss of consciousness -it is brief symptoms around 10min to 10days -symptoms recover within 30mins & full recovery is commonly 7-10days Complex concussion: it is traumatic concussion after simple concussion as well as repeated concussion -have constant symptoms for long term They have loss of memory around more than 30min for more than 24hours -it is linked with loss of some motor task and other sensory type Ongoing concussion evaluation: requires multiple diagnosis test for brain imaging and the test of the concussion Neurological, cognitive, brain test/imaging Management/Prevention: physical & cognitive rest 24-48hours -need progressive return to play (min 24h/stage)  do not return to the activity right away on same day -use protective equip like helmets & seat belt, approp techniques, education, etc. Reading Questions: 1.The current recommendation for the acute concussion treatment in children allows more of the movement and activities that normally avoided - 28% who did activities - prone to injuring again, but less severe than who did not participate in activities - 40% not do the activities -led to post concussion -depression & anxiety fatigue and physiological depressant 2.It may include recovery through rewiring from damaged tissues or use of stimulation of the brain to constantly heal the concussion as a natural healing process - faster recovery through active child with neural plasticity also with increase in blood flow allowing more faster repair the neural damages 3.The limitations of this study will be when it is applicable -is there certain age gap? How reliable is this recommendation? -this is cross sectional study -we cannot find the causality of the potential benefit outcome -still we can't just assume this Spinal curvatures: revisit –S curvature formation from infant to adult Postural Deviations: lordosis-ideal, hyperlordosis-excessi
