Ils présentent toutefois aussi des risques de blessures: près de la moitié des lésions chez les enfants qui sont soignées aux services des urgences tous les ans sont liées aux sports et aux loisirs. Le crâne offre une certaine protection au cerveau​, mais de graves traumatismes peuvent tout de même se produire sans le port du casque.</p><h2>À retenir</h2> <ul> <li>En cas d’accident, les casques sont conçus pour répartir la force d’impact sur une plus grande surface et prévenir les impacts directs avec le crâne.</li> <li>Le port du casque peut faire toute la différence entre subir un traumatisme grave et se sortir indemne d’un accident.</li> <li>Il existe des casques adaptés à la plupart des sports. Les enfants devraient être munis d’un casque se prêtant à l’activité qu’ils effectuent. Consultez l’étiquette d’homologation du casque afin de savoir pour quelles activités ce dernier est approprié.</li> <li>La plupart des pays ont adopté des règlements qui visent l’utilisation et la conception des casques. Assurez-vous toujours que votre enfant est muni d’un casque même si vous n’êtes assujetti à aucune loi rendant son port obligatoire.</li> </ul><h2>Comment les casques permettent de prévenir les traumatismes crâniens</h2> <p>Le port du casque peut, dans de nombreux cas, faire toute la différence entre se sortir indemne d’un accident et y subir un traumatisme grave.</p> <p>En règle générale, les casques sont conçus afin de:</p> <ul> <li>permettre à la tête de ralentir plus progressivement</li> <li>répartir la force d’impact d’une percussion ou d’une chute sur une plus grande surface</li> <li>prévenir les impacts directs avec le crâne.</li> </ul> <p>Le bon casque peut assurer une protection contre les traumatismes crâniens au cours de la pratique des sports et des activités qui suivent:</p> <ul> <li>bicyclette</li> <li>football</li> <li>hockey</li> <li>équitation</li> <li>patinage sur glace</li> <li>conduite de véhicules hors route et de véhicules tout-terrain (VTT)</li> <li>rugby</li> <li>ski et planche à neige.</li> </ul> <p>Il ne s’agit pas des seuls sports dont les adeptes ont avantage à être muni d’un casque. Le port du casque durant bon nombre d’autres activités permet de réduire considérablement les traumatismes crâniens qui y sont associés.</p> <h2>Caractéristiques des casques permettant de prévenir les traumatismes crâniens</h2> <p>Les matériaux et la forme des casques constituent d’importantes caractéristiques en vue de minimiser le risque de lésions au cerveau.</p> <ul> <li>La majorité des casques sont garnis de mousse ou d’un autre matériau comprimable. Si la tête subit un impact, le crâne s’enfonce dans la mousse, puis sa projection est ralentie sur quelques centimètres. Par après, la mousse est déformée, mais le crâne et le cerveau s’en portent nettement mieux.</li> <li>Au fil du temps, on a modifié la forme des casques afin d’en améliorer l’ajustement et la stabilité. Un casque mal ajusté n’offre aucune protection. Si vous ou votre enfant avez essayé de porter un casque auparavant pour finalement y renoncer parce qu’il vous gênait ou ne vous tenait pas sur la tête, ajustez-en les courroies ou la garniture intérieure ou utilisez-en un différent.</li> <li>Certains casques présentent des douzaines d’ouverture pour l’aération afin de protéger la tête. Ils sont cependant plus chers étant donné qu’ils offrent une mousse de meilleure qualité.</li> </ul><h2>Types de casques</h2><p>Il existe des casques adaptés à la plupart des sports. Les enfants devraient être munis d’un un casque se prêtant à l’activité qu’ils effectuent. Par exemple, porter un casque de vélo pour jouer au hockey ou l’inverse comporte des risques.</p><p>Même si les modèles varient, il existe deux grandes catégories de casques pour les sports non motorisés:</p><ul><li>les casques protégeant la tête contre un seul impact</li><li>les casques protégeant la tête contre des impacts multiples.</li></ul> <h3>Casques protégeant la tête contre un seul impact</h3><p>Ces casques sont conçus pour absorber la force d’impact d’un seul accident grave et doivent donc être remplacés suite à une collision.</p><ul><li>La protection de mousse, qui est du polystyrène expansé, est comprimée au moment de l’impact et ne reprend pas sa forme originale.</li><li>Ces casques peuvent servir à faire du vélo sur des voies publiques, la plupart des types de randonnée à vélo tout-terrain, du ski et de la planche à neige. Ils offrent aussi une protection adéquate pour la pratique du patin à roues alignées, à moins que votre enfant fasse des acrobaties, joue au hockey sur ces patins ou a souvent des accidents.</li></ul><h3>Casques protégeant la tête contre des impacts multiples</h3><p>Les casques contre les impacts multiples peuvent absorber le choc d’un certain nombre d’accidents. Ces casques relativement nouveaux peuvent souvent servir à plus d’un sport.</p><ul><li>Ils sont garnis de polypropylène expansé ou de mousse de polyuréthane capable de se comprimer et de se décomprimer pour reprendre sa forme de départ.</li><li>Comme ils sont rigides, ils permettent de répartir la force d’impact sur une plus grande surface.</li><li>Ils peuvent être utilisés pour le vélocross, la planche à neige tout-terrain, le trial, la motocyclette tout-terrain, la planche à roulettes, le patin à roues alignées acrobatique, le parkour, le patinage sur glace, le hockey et l’escalade de rocher.</li><li>Ils ne se prêtent pas au ski alpin, au ski nautique, aux sauts à cheval ou autres sports équestres, aux sports d’équipe ou aux activités motorisées comme la conduite d’un véhicule tout-terrain.</li></ul>

They also carry a risk of injury: almost half of children’s injuries treated in emergency departments every year occur during sports and recreation activities. The skull offers some protection to the brain, but serious injuries can still occur without a helmet.</p><h2>How the skull protects the brain</h2> <p>The skull has evolved features that protect the brain in several ways.</p> <ul> <li>The thick bone of the forehead, part of the frontal bone, protects the large masses of brain called the frontal lobes. But to keep the head light, much of the skull is more delicate. For instance, the temporal bone around the temple is quite thin.</li> <li>The skull's nearly spherical shape efficiently protects the delicate brain against pressure and impact. Since the brain has about the same consistency as jelly, it needs a lot of protection.</li> <li>A nutrient mixture, the cerebrospinal fluid or CSF, bathes the brain and cushions it against collisions with the inside of the skull. A three-layered membrane system called the meninges fits between the CSF and the skull.</li> </ul> <p>Despite this padding, some accidents can cause the brain to shift rapidly and bounce off the inside of the skull with enough force to do damage. A sudden impact can also damage the brain’s tissues or connections between brain cells or cause the blood vessels that feed the brain to rupture. The surface of the head can also be cut or bruised, especially if it hits a sharp object. In certain types of injuries, the skull may be fractured.</p> <h3>How children's brains and skulls differ from those of adults</h3> <p>Children's brains and skulls have a few advantages over those of adults.</p> <ul> <li>Children's tissues are more resilient. Their blood vessels are less likely to tear under twisting or squeezing stress.</li> <li>Children's heads and brains are smaller, so the forces acting to deform or stretch the brain are lessened.</li> </ul> <p>However, children, especially young children, fall much more often than adults. They also do not act to protect their heads when falling. This is part of the reason why those under 19 years of age make up nearly a third of all hospitalizations for head injuries. It is also why it is so important for a child to wear a <a href="/Article?contentid=1983&language=English">properly-fitted helmet for sports and recreation activities</a>.</p><h2>Key points</h2> <ul> <li>In case of an accident, helmets are designed to spread the impact over a larger area and prevent direct impact to the skull.</li> <li>A helmet can make all the difference between serious injury and walking away from an accident unharmed.</li> <li>Most sports have their own helmet design. Children should wear the right helmet for their activity. You can check the suitability of a helmet by looking at its certification sticker.</li> <li>Most countries have regulations covering helmet use and helmet design. Even when no laws exist always make sure your child wears a helmet.</li> </ul><h2>How you can help your child</h2> <p>Head injury can result in life-long disability. Helmets are a simple, proven way to prevent possible tragedies and provide peace of mind.</p> <p>Clearly, no helmet can protect against all possible injuries. It is important to teach children safety skills as well. In contact sports, rules to protect the head and neck are another important part of preventing injury.</p> <p>If your child loses consciousness or may have lost consciousness after a head injury, see a doctor, even if your child was wearing a helmet when injured. The doctor can check if your child has a <a href="/Article?contentid=766&language=English">concussion</a>.</p> <p>If a head injury is serious enough that concussion could be a concern, you will also need to replace the helmet.</p><h2>How helmets work to prevent injury</h2> <p>In many cases, a helmet can make all the difference between serious injury and walking away from an accident unharmed.</p> <p>In general, helmets are designed to:</p> <ul> <li>help the head slow down more gradually</li> <li>spread the impact of a knock or a fall over a larger area</li> <li>prevent direct impact to the skull</li> </ul> <p>The right helmet can protect against head injury in the following sports and activities:</p> <ul> <li>bicycling</li> <li>football</li> <li>hockey</li> <li>horseback riding</li> <li>ice skating</li> <li>off-road and all-terrain vehicle (ATV) driving</li> <li>rugby</li> <li>skiing and snowboarding</li> </ul> <p>These are not the only sports that may benefit from helmet use.

This usually includes bicycle passengers, for example children riding behind a parent. Individual cities and towns may also have their own helmet laws.</p> <p>In general, parents of children under 16 must make sure that their child wears a helmet. They may face a fine if the law is not obeyed. Children who are 16 and 17 years old are responsible for their own helmets.</p> <p>Depending on the laws of their province or territory, children may also have to wear a helmet when riding:</p> <ul> <li>scooters, skateboards, in-line skates or roller skates</li> <li>horses</li> <li>off-road and all-terrain vehicles</li> <li>snowmobiles and sleds towed by snowmobiles</li> <li>motorcycles and mopeds.</li> </ul> <p>Even where no law specifies helmet use, always make sure your child wears a helmet.</p> <h3>Helmet safety standards</h3> <p>Several organizations create standards that helmets should meet for different types of activities. They then test them to make sure they are up to the challenge. When choosing a helmet, look for one that has been certified by a national safety organization.</p> <p>While it is generally better to wear different helmets for different activities, some helmets are certified for more than one activity. Check the helmet certification sticker on top of the helmet to see which activities the helmet is suited for.</p> <h2>Helmets have limits</h2> <p>It is important for everyone, especially children, to understand that helmets do not make them invincible. Here are some situations where helmets fail.</p> <ul> <li>The impact on the head may exceed what the helmet was designed to handle. Typically, a helmet can protect the brain in a fall, but it cannot prevent serious harm if, for example, a child rides head-first into a tree. Collisions between a cyclist and a car will also often be more than a helmet can handle.</li> <li>A helmet only protects what it covers. Downhill mountain bike racers and bicycle motocross riders often add chin and jaw protection by wearing full-face helmets, but a rider covering a long distance or climbing hills will probably find these helmets trap too much heat.</li> <li>A helmet must fit properly to have a chance to be effective. A child must wear and secure the helmet correctly. Most helmets come with fitting instructions.</li> <li>A helmet that has been dropped or has been worn while a child had an accident may not be effective, even if it does not look damaged. In these cases, it is better to get a new helmet.</li> </ul><h2>Source</h2><p>Injury Prevention Committee, Canadian Paediatric Society. (2012).
