Sports-Related Head Injury

An approximated 1.7-3.8 million traumatic brain injuries annually in the US. According to the CDC, 10% of these arise due to sports and recreational activities. Amongst American children and adolescents, sports and recreational activities contribute to over 21% of traumatic brain injuries. A head injury received while playing sports may range from a mild physical trauma such as a scalp contusion or laceration to severe TBI with concurrent bleeding in the brain or coma. You must recognize when a head trauma is severe or has resulted in a TBI, as it is exceedingly important to seek immediate medical attention. While most brain injuries are self-limiting with symptoms resolving in a week, a growing amount of research has established that the sequelae from recurrent minor impacts is significant in the long term.

Traumatic Brain Injury

A traumatic brain injury (TBI) is a form of acquired brain injury from a blow or jolt to the head or a penetrating head injury, which disrupts the normal function of the brain. TBI may result when the head suddenly and violently hits an object, or when an object pierces the skull and enters brain tissue. Symptoms of a TBI may be mild, moderate, or severe, depending on the extent of damage to the brain. Mild cases (mild, traumatic brain injury; mTBI) may result in a brief change in mental state or consciousness, while severe cases may result in extended periods of unconsciousness, coma, or death.

Individuals with TBI may experience one or more of the following:

• Pain: Constant/recurring headache
• Motor Dysfunction: Inability to coordinate motor functions or disturbance with balance
• Sensory: Changes in ability to hear, see, or taste; dizziness; hypersensitivity to light or sound
• Cognitive: Agitation; overstimulated by environment; confusion; shortened attention span; easily distracted; difficulty following directions or understanding information; feeling of disorientation and confusion and other neuropsychological deficiencies
• Speech: Difficulty finding the "right" word; ; dysarthric or slurred speech; difficulty expressing words or thoughts

Concussions

Concussions often affect athletes in both contact and non-contact sports and are diffuse brain injuries that traumatically induce alterations of mental status. A concussion may result from shaking the brain within the skull and, if severe, can cause shearing injuries to nerve fibers and neurons.

The 5th International Conference on Concussion in Sport held in Berlin, Germany, in 2016 defined Sport-related Concussion as:

Sport-related concussion is the historical term representing low velocity injuries that cause brain ‘shaking’ resulting in clinical symptoms and that are not necessarily related to a pathological injury. Concussion is a subset of TBI and will be the term utilized in this document. It was also noted that the term commotio cerebri is often utilized in European and other countries. Minor revisions were made to the definition of concussion, which is defined as follows:

Sport related concussion is a traumatic brain injury induced by biomechanical forces.

Several common features that may be utilized in clinically defining the nature of a concussive head injury (sport related) include:

1. May be caused by direct blow to the head, face, neck, or elsewhere on the body with an “impulsive” force transmitted to the head.
2. Typically results in the rapid onset of short-lived impairment of neurological function that resolves spontaneously. However, in certain cases, signs and symptoms evolve over a number of minutes to hours.
3. May result in neuropathological changes, but the acute clinical symptoms largely reflect a functional disturbance rather than a structural injury. As such, no abnormality is seen on standard structural neuroimaging studies.
4. Results in a range of clinical symptoms that may or may not involve loss of consciousness. Resolution of the clinical and cognitive symptoms typically follows a sequential course. However, in certain cases symptoms may be prolonged.

The clinical signs and symptoms should not be explained by drug, alcohol, or medication use, other injuries (like cervical injuries, peripheral vestibular dysfunction, etc.) or other comorbidities (e.g., psychological factors or coexisting medical conditions).

Grading the concussion can be a helpful tool in the management of the injury, depending on:

1. Presence/absence of loss of consciousness
2. Duration of loss of consciousness
3. Duration of post-traumatic memory loss
4. Persistence of symptoms, including headache, dizziness, lack of concentration, etc.

Some team physicians and trainers evaluate an athlete's mental status through a 5-minute series of questions and physical exercises (Standardized Assessment of Concussion [SAC]).  Recently, teams have employed ImPACT, a 25-minute computer-based testing program specifically designed for the management of sports-related concussion. A player with a concussion is 3-6x more likely to sustain another one. While the decision when an athlete is ready to return to play isn't straightforward, every player could benefit from baseline neurological testing before the season so that the results may be utilized for comparison in the event the athlete receives a blow to the head.

Note: No evidence demonstrates that  all participants in contact collision sports should have baseline computerized neuropsychological (NP) tests. NP tools such as ImPACT/Cogsport, as well as SCAT3 have yet to be proven reliable or validated. These screening tests can be utilized only as a tool in the expert medical diagnosis and return to play decision-making process.

Second Impact Syndrome (SIS) is an acute, sometimes fatal, brain swelling that occurs when a second concussion is sustained before complete recovery from a previous one. This repeat injury causes vascular congestion and increases intracranial pressure, which may be difficult or impossible to control. The risk for SIS is higher for sports such as boxing, football, ice or roller hockey, soccer, baseball, basketball, and snow skiing.

Coma

Coma refers to a profound or deep state of unconsciousness. An individual in a coma is alive, but he or she is not able to respond to his or her environment. The unconscious state has variability and may be very deep, where no amount of stimulation will cause the person to respond.  In other cases, the person in a coma may move, make noise, or respond to pain, but is ultimately unable to obey simple, one-step commands such as "hold up two fingers" or "stick out your tongue." Although higher brain functions are impaired, key functions like breathing and circulation remain intact in comatose patients. The process of recovery from coma is a continuum along which a person gradually regains consciousness.

For people that sustain severe injury to the brain and are comatose, recovery is variable. The more severe the injury, the more likely the result will include permanent impairment.

The Glasgow Coma Scale is administered upon admission to the hospital or by paramedic first responders to establish a baseline level of consciousness, motor function, and eye findings. Abilities are scored from 3 -15 on the GCS, with higher scores correlating with less severe injuries. Frequent evaluations of the patient are imperative to help assess neurologic improvement or deterioration.

Brain-imaging technologies, particularly computerized tomography (CT or CAT scan), can offer important immediate information about a person's status. The purpose of performing an emergency CT scan is to rule out a large mass lesion (hematoma) that may be compressing the brain. An MRI can be utilized to image subtle changes that may not be captured by a CT scan.

Chronic Traumatic Encephalopathy

Chronic traumatic encephalopathy (CTE) is a progressive degenerative disease typically found in individuals that have sustained repeated head injuries in the past (including concussions during contact sports). The symptoms usually develop over several years to decades after repeated injuries and consist of cognitive deficits such as learning disabilities, disinhibition, and memory disturbances, as well as mental illnesses such as depression, anxiety, and suicidal ideation. As the disease progresses, some patients may experience progressive dementia and motor symptoms such as balance instability and extrapyramidal disorders.

A research study conducted in 2017 at Boston University examined 202 brains from deceased football players and found that 177 of them (87%) had signs of chronic traumatic encephalopathy from repeated blows to the head.

Incidence

The U.S. Consumer Product Safety Commission (CPSC) tracks injuries through its National Electronic Injury Surveillance System (NEISS).

There were an approximated 454,407 sports-related head injuries treated at U.S. hospital emergency rooms in 2018. This number represents a decrease of nearly 32,875 sports-related injuries from the previous year. Of all the sports noted below, most of them posted a decrease in the number of injuries treated from 2017.

The actual incidence of head injuries may potentially be much higher

1. In the 2018 report, the CPSC excluded approximates for product categories yielding 1,200 injuries or less. Those that had very small sample counts and those that were limited to a small geographic area of the country.
2. Additionally, the system does not track many less severe head injuries treated at physicians' offices, immediate care centers, or are self-treated. Sports/recreational activities, in addition to the equipment and apparel utilized in these activities are included in these statistics. For example, swimming-related injuries include the activity as well as diving boards, equipment, flotation devices, pools, and water slides.

The following sports/recreational activities represent the categories contributing to the highest number of approximated head injuries treated in U.S. hospital emergency rooms in 2018.

• Cycling: 64,411
• Football: 51,892
• Baseball and Softball: 24,516
• Basketball: 38,898
• Powered Recreational Vehicles (ATVs, Dune Buggies, Go-Carts, Mini bikes): 30,222
• Soccer: 26,955
• Skateboards: 10,573
• Exercise & Equipment: 37,045
• Horseback Riding: 6,141
• Golf: 6,357
• Hockey: 7,668
• Trampolines: 8,956
• Rugby/Lacrosse: 10,901
• Skating: 7,143
• Playground Equipment: 38,915

The top 10 sports-related head injury categories for children ages 14 and younger:

• Playground Equipment: 35,058
• Football: 31,277
• Basketball: 20,242
• Cycling: 19,921
• Baseball and Softball: 12,065
• Soccer: 12,709
• Swimming: 9,265
• Trampolines: 7,921
• Powered Recreational Vehicles: 6,036
• Skateboards: 3,101

*Note: Reported incidence is known to be significantly under-reported (up to 50%, McCrea Clin J Sports med 13:13-17, 2004) and do not reflect those that are treated by family doctors or other para-medical professionals.

TREATMENT

Anyone who displays signs or symptoms of moderate to severe traumatic brain injury should receive medical attention ASAP. Although little may be done to reverse brain damage, stabilizing the individual with TBI and preventing further injury is crucial. Most studies indicate that once brain cells are damaged, they do not regenerate for the most part. However, recovery after brain injury can take place as the surrounding tissue of the brain may make up for the injured areas by rerouting the information and functions of the damaged tissue.

For mild traumatic brain injuries, individuals should be monitored closely at home for persistent, worsening, or new symptoms. Indications for returning to work, school, or physical activities are based upon the physician’s recommendations.

Moderate to severe traumatic brain injuries require emergent medical care to ensure that the individual has proper oxygen supply to the brain and the rest of the body, adequate blood flow, and a normal blood pressure. Further medical management may be required based on the patient’s symptoms (e.g. people who develop seizures after their injury may be given anti-seizure medications). If the patient is severely injured, a neurosurgeon may need to remove or repair hematomas (ruptured blood vessels), contusions (bruised brain tissue) or skull fractures.

Most people with a significant brain injury will require some form of rehabilitation to relearn basic skills and perform their daily activities. The type and duration of rehab depends on the severity of the injury and what part of the brain was injured.

Boxing

Over time, professional and amateur boxers often suffer permanent brain damage.

According to the Journal of Combative Sport, from January of 1960 to August of 2011, 488 boxing-related deaths occurred. 66% of these deaths were due to head, brain, or neck injuries; one was attributed to a skull fracture.

There are boxers with minimal involvement and those that are so severely affected that they require institutional care. Some have varying degrees of speech difficulty, stiffness, unsteadiness, memory loss, and inappropriate behavior. In several studies, 15-40% of ex-boxers have been found to have symptoms of chronic brain injury. Most of these boxers have mild symptoms. Recent studies have shown that most professional boxers (even those without symptoms) have some degree of brain damage.

Cheerleading

Cheerleading has evolved drastically in the last 20 years, with increasingly difficult acrobatic stunts performed. A number of high school and college level schools have limited the types of stunts that can be attempted by their cheerleaders. Rules and safety guidelines now apply to both practice and competition.

According to 2010 cheerleading data from the CPSC, head and neck injuries accounted for 19.3% of total cheerleading injuries. During the 2010-2011 school year head injuries were associated with 1579 concussions, 361 contusions and 2,292 internal injuries; neck injuries accounted for 118 contusions, 16 fractures and 1,301 sprains/strains.

In its Catastrophic Sports Injury Report for fall 1982 through spring 2011, the National Center for Catastrophic Sport Injury Research at the University of North Carolina (UNC) noted one direct high school cheerleading catastrophic injury during the 2010-2011 school year. A high school cheerleader collided with another cheerleader during practice, elbowing her in the temple. The result was two skull fractures, seizures, and a medically induced coma. Recovery at the time remained incomplete.

UNC also reported that college cheerleading was not associated with any direct injuries during that school year.

A 2009 study by the Center for Injury Research and Policy of The Research Institute at Nationwide Children's Hospital yielded:

• The majority (96%) of the reported concussions and closed-head injuries were led by the cheerleader performing a stunt.
• Nearly 90% of the most serious fall-related injuries were sustained while the cheerleaders were performing on artificial turf, grass, traditional foam floors or wood floors.

A 2012-2013 RIO study by the Nationwide Children’s Hospital yielded:

• Cheerleading yielded 0.73 injuries per 1,000 athletic exposures in the 2012-2013 school year.
• Head/face injuries accounted for 36.5% of all cheerleading injuries in the 2012-2013 school year.

The National Cheer Safety Foundation offers resources and safety information specific to cheerleading, including news articles such as this.

Cycling

Annually, over 500,000 people visit emergency rooms in the U.S. to be treated for bicycle-related injuries. In 2009, nearly 85,000 of those were head injuries. There are about 600 deaths a year, with ⅔ attributed to TBI. It is approximated that up to 85% of these are preventative with proper helmet use, like those approved by The Snell Memorial Foundation, American National Standards Institute (ANSI) or American Society for Testing and Materials (ASTM). It is essential that the helmet fits securely while the user is riding or if he or she takes a fall. According to Safe Kids Worldwide, more children from ages five to 14 visit emergency rooms for biking-related injuries than from any other sport. Helmets can reduce the risk of severe brain injuries by 88%. However, about 55% of children are reported not always wearing a helmet while bike riding.

The following facts/statistics are from Safe Kids USA:

• Head injury is the leading cause of wheeled sports-related death and the most important determinant of permanent disability after such a crash.
• Without proper protection, a fall of two feet or more often results in a skull fracture or other TBI.
• about 50% of U.S. children between 5-14 years old own a helmet but only 25% report regularly wearing it while bicycling.
• Universal use of bicycle helmets by children ages 4 to 15 could prevent 45,000 head injuries.
• Helmets reduce the risk of head injury by at least 45%, brain injury by 33%, facial injury by 27%, and fatal injury by 29%. 8 states and the District of Columbia require children to wear a helmet while participating in wheeled sports such as riding scooters, in-line skates, or skateboards.
• One study found that the rate of bicycle-helmet use by children ages 14 and under was more than 2x as high in a county with a fully comprehensive bike-helmet law than in a similar county with a less comprehensive law.

Safe Kids Worldwide further reported that in 2010, 112 children under the age of 19 died while riding a bike. This is the smallest number of deaths since 1999, and a 56% reduction in the number of deaths since, with a 59% decrease in the death rate.

Football

The National Center for Catastrophic Sport Injury Research (NCCSIR) also tracks a number of statistics for "catastrophic" football injuries, which it defines as those resulting in brain, or spinal cord injury, or skull or spine fracture.

Recent findings in the Annual Survey of Catastrophic Football Injuries, 1977-2012, include the following:

• Throughout the 2012 football season, there were three cervical cord injuries with incomplete neurological recovery. One of the injuries occurred at the high school level and two at the college level. The 2012 total is 11 fewer than the 14 in 2008, 6 fewer than the 9 in 2009, and 5 fewer than the 8 in 2011.
• The incidence of catastrophic injuries is very low on a 100,000-player exposure basis. For the about 4,200,000 participants in 2012, the rate of cervical cord injuries with incomplete neurological recovery was 0.07 per 100,000 participants.
• The rate of injuries with incomplete neurological recovery in high school and junior high school football was 0.07 per 100,000 players (1,500,000 high school and junior high school players). College level was 2.66.
• A majority of catastrophic spinal cord injuries usually occur during games. During the 2012 season, two injuries took place in games and one in a weight-lifting session.
• Tackling and blocking have been associated with the majority of catastrophic cervical cord injuries. In 2012, two injuries were by tackling and one in a weight-lifting session. Tackling has been associated with 67% of the catastrophic injuries since 1977.
• The majority of catastrophic injuries occur while playing defense. In 2012, two players were on defense and one in a weight-lifting session. Since 1977, 228 players with permanent cervical cord injuries were on the defensive side of the ball and 55 were on the offensive side, with 44 unknown. Defensive backs were involved with 34.6% of the permanent cervical cord injuries followed by members of the kick-off team at 9.2% and linebackers at 9.5%.
• During the 2012 football season, five brain injuries resulted in incomplete recovery. Four were at the high school level and one at the college level. This is a decrease of nine, compared to the 2011 data.
• In 2012, there were five injuries involved either a head or neck injury, but the athletes had full neurological recovery. High school athletes were associated with four and college football was associated with one.

A few football injuries also have resulted in fatalities, according to the National Center for Catastrophic Sport Injury Research's Annual Survey of Football Injury Research, 1931-2012:

• 2 fatalities directly related to football during the 2012 football season. Both fatalities were in semi-professional football. There is only one other year where there were no direct fatalities in high school and college football and that was in 1990.
• Rate of direct fatal injuries is very low on a 100,000 player exposure basis. For the about 4,200,000 participants in 2012, the rate of fatalities was 0.04 per 100,000 participants.
• The rate of direct fatalities in high school (grades 9-12) was 0.00 per 100,000 participants. The rate of direct fatalities in college was 0.00 per 100,000 participants. The rate for all other areas of football was 0.06 per 100,000 participants.
• Most direct fatalities occur during regularly scheduled games, and in 2012 this was true with both direct semi-professional fatalities occurring in games.

According to the same report by NCCSIR, a number of the players associated with brain trauma complained of headaches or had a previous concussion prior to their deaths.

The National Federation of State High Schools released the following statement on February 23, 2010: "Effective with the 2010 high school football season, any player who shows signs, symptoms or behaviors associated with a concussion must be removed from the game and shall not return to play until cleared by an appropriate health-care professional." The new concussion language is now in all NFHS rules books as well as the "NFHS Suggested Guidelines for Management of Concussion."

More recently, long-term implications of concussion have been discussed at length in the media, sparked by the controversy between the NFL and its former players. An ESPN news story from early November 2013 covered the chronic traumatic encephalopathy diagnosis of three ex-NFL players. Additionally, ESPN also reported that last year UCLA tested five other former players and was able to diagnose all five as having signs of CTE, marking the first time the disease has been recognized in living patients.

The National Athletic Trainers' Association (NATA) and the American Football Coaches Association (AFCA) Task Force, headed by Ron Courson has focused on two primary problems associated with head contact.

• Head-down contact still occurs frequently in intercollegiate football
• Helmet-contact penalties are not adequately enforced

Rule changes implemented by the National Collegiate Athletic Association (NCAA) related to head-down contact and spearing in collegiate football have been given to all coaches and officials throughout the country. The objective is to eliminate injuries resulting from a player using his helmet in an attempt to punish an opponent.

With the rule changes and more diligent enforcement of the rules, there is hope that a significant reduction in head and neck injuries will result.

The NCAA revised its 16-year-old guidelines on treatment of concussion in the NCAA Sports Medicine Handbook to better provide member institutions with appropriate responses to concussion injuries and procedures for returning athletes to competition or practice. According to page 59 of the 2013-2014 edition, "…Any athlete who is diagnosed with a concussion must not return to play or practice that day and must be cleared by a healthcare professional before returning to play or practice."

The "Concussion Diagnosis and Management" section details circumstances in which an athlete should be withheld from competition pending clearance by a physician.

Football-related Head and Neck Injury Prevention Tips

• All players should receive pre-season physical exams, and those with a history of prior brain or spinal injuries, including concussions, should be identified.
• Coaches and officials should discourage players from using the top of their football helmets as battering rams when blocking, hitting, tackling, and ball carrying.
• Coaches, physicians, and trainers should ensure that the players' equipment is properly fitted, especially the helmet, and that straps are always locked.
• The rules prohibiting spearing (hitting another player with the crown of the helmet) should be enforced in practice and games.
• Ball carriers should be taught not to lower their heads when making contact with the tackler to avoid helmet-to-helmet collisions.
• Football players should receive adequate preconditioning and strengthening of the head and neck muscles.
• Coaches must be prepared for a possible catastrophic spinal cord injury. The entire staff must know what to do in such a case. Being prepared and well informed might make all the difference in preventing permanent disability.

Horseback Riding

Head injuries comprise about 18% of all horseback riding injuries, but they are the number one reason for hospital admission. A 2007 study by the Centers for Disease Control and Prevention found that horseback riding resulted in 11.7% of all traumatic brain injuries in recreational sports from 2001 to 2005 (the highest of any athletic activity). Of the approximated 14,446 of these injuries treated in 2009, 3,798 were serious enough to require hospitalization. Subdural hematomas and brain hemorrhages made up many of the serious injuries. According to the Equestrian Medical Safety Association, head injuries account for an approximated 60% of deaths resulting from equestrian accidents.

Factors may increase the risk of falling (like a green horse, slippery footing or bareback riding), but it is the height from which the rider falls that most greatly affects the injury severity. According to the Ontario Equestrian Federation, a rider sitting on a horse is elevated eight feet or more above the ground: a fall from just two feet can cause permanent brain damage. Riders ages 10-14 are most likely to be involved in an accident with a horse.

Although serious head injury can still occur while wearing a helmet, the data very clearly shows the severity of the head injury may be greatly decreased with helmet wear. According to the New England Journal of Medicine, helmets reduce head and brain injuries by 85%. While helmets are required in equestrian sports that involve jumping, including eventing and show jumping, while competing in high-level dressage competitions, the riders generally wear top hats, which provide no protection. Accidents are less common in competitive dressage, but accidents still occur. While most dressage riders do not wear helmets even when practicing, they are allowed during practice and competition.

The U.S. Equestrian Federation strongly encourages all riders while riding anywhere on the competition grounds to wear protective headgear with harness secured which passes or surpasses ASTM (American Society for Testing and Materials)/SEI (Safety Equipment Institute) standards for equestrian use and carries the SEI tag.

Snow Skiing/Snowboarding

According to a John Hopkins Medicine-led study, about  10 million Americans ski or snowboard in the United States each year, with about 600,000 reported annually. Severe head trauma accounts for about 20% of all skiing and snowboarding-related injuries, and of those head injuries, 22% are severe enough to cause loss of consciousness or concussion. Head injuries are the most frequent cause of death and severe disability among skiers and snowboarders.

As stated in the National Ski Areas Association’s (NSAA) 2012-2013 National Demographic Study, 70% of skiers and snowboarders wore helmets during the most recent ski season. This shows a 5%increase from the 2011-2012 season. Among those interviewed, helmet usage has increased by 180% since the 2002-2003 season, when only 25% of skiers and snowboarders reported wearing helmets.

More importantly, 80% of skiers and snowboarders age 17 and under reported wearing helmets on the slopes during the 2012-2013 ski season. The NSAA National Demographic Study was compiled from more than 130,000 interviews of skiers and snowboarders nationwide.

The 2012-2013 NSAA study also revealed that:

• 89% of children 9 or younger reported helmet usage in the 2012-2013 ski season
• 83% of children between the ages of 10-14 reported wearing helmets
• 81% of adults aged 65+ reported helmet usage
• Skiers and snowboarders ages 18-24 have traditionally represented the lowest percentage of helmet use among all age groups. In the 2012-2013 season, 60% of all 18 to 24 years olds interviewed wore helmets, a 13-percent increase from the 2011-2012 season, when only 53% wore helmets.

NSAA recently launched a revamped Lids on Kids website designed to provide parents with pertinent helmet-safety information; it includes simple helmet-sizing instructions to help ensure a proper fit.

Helmet Usage

In 2011, New Jersey became the first state to require those under the age of 18 wear a helmet while skiing or snowboarding. Currently, no other state laws mandating helmets for skiing or any winter sports exist. Ski resorts in Aspen, Colo., mandate skiers under age 12 wear helmets. Following the high-profile skiing-related deaths of Michael Kennedy in December of 1997, Sonny Bono in January of 1998 and Natasha Richardson in March of 2009, an increase in the number of skiers wearing helmets has been noted in several studies.

Meanwhile, helmet use has been mandatory for snowpark users in Quebec. They have been since the winter of 2006-2007, according to the Quebec Ski Areas Association (ASSQ). And in January of 2010, the may adian Ski Council (CSC) issued the following national policy:

"The Canadian Ski Council recommends wearing helmets for skiing and riding. Skiers and snowboarders are encouraged to educate themselves on the benefits and limitations of helmet usage. The primary safety consideration, and obligation under the Alpine Responsibility Code, is to ski and ride in a controlled and responsible manner."

The policy developed after the CSC showed that helmet usage in Canada is increasing steadily, with more than 50% of Canadian skiers and boarders wearing helmets.  Usage is much greater among youth, reaching 90% in many areas. To ensure compliance with this initiative, the CSC notes that may adian ski areas have invested heavily in making the sport safer, with improved signage, better grooming, and safer equipment; areas have purchased more than 50,000 rental helmets to include in their rental packages, which are available at nearly all may adian ski areas.

In a February 2010 release from Quebec's Trauma Centres and the ASSQ, Dr. Tarek Razek, the director of the Montreal General Hospital Trauma Program, said, "Wearing a helmet reduces the risk of head injuries in skiers and snowboarders by about 35%." Dr. Razek also advocates helmet use in other sports like cycling and rollerblading.

As part of a survey of 80 Canadian ski areas:

• Area operators approximate that 55% of all skiers and boarders wore helmets. Quebec had the highest rate of usage at 65%, with the lowest rate in Western may ada at 50%.
• The Grade 4/5 Snowpass program, which had 41,000 youth participants in 2008-2009, provides reduced-cost lift tickets and other specials for participants. Fifty-four% of the parents of Snowpass holders reported wearing helmets regularly, and 93% of youth participants reported wearing helmets on a regular basis.
• A survey of 1,500 attendees conducted at the Toronto Ski Show in October of 2008 found that 55.3% of men and 57.6% of women wore helmets all or most of the time. Older skiers and boarders had a higher usage of helmets than younger adults.

Meanwhile, according to the 2012-2013 National Demographic Study of Skiers and Boarders, the National Ski Area Association in the U.S. found the following;

• 71% of survey respondents were wearing a helmet when interviewed, up six% in the previous season.
• Helmet usage increases with ability level, rising from 26% usage by beginners, to 38% by intermediates, to 55% by advanced/expert participants.
• Helmet usage is higher for children ages 9 and under (89%) and 10-14 (83%), and adults ages 55-64 (76%) and 65+ (81%) than for other age groups. Usage is lowest among 18-24-year-olds (62%).

Soccer

Protection against head injuries in soccer is complicated, as heading is an established part of the game, and any attempt to protect against head injuries must allow the game to be played without modification. Several head guards have been developed to reduce the risk of head injuries in soccer. One independent research study found that none of the products on the market provide substantial benefits against minor impacts, such as heading with a soccer ball.

A McGill University study found more than 60% of college-level soccer players reported symptoms of concussion during a single season. Although the percentage at other levels of play may differ these data indicate head injuries in soccer are more frequent than most presume.

According to CPSC statistics, 40% of soccer concussions are attributed to head to player contact; 10.3% are head to ground, goal post, wall, etc.; 12.6% are head to soccer ball, including accidents; and 37% are not specified.

Prevention Tips

Buy and use helmets or protective headgear approved by the ASTM for specific sports. The ASTM has vigorous standards for testing helmets for many sports; helmets approved by the ASTM bear a sticker stating this. Helmets and headgear can be bought in many sizes and styles for many sports and must properly fit to provide maximum protection against head injuries.

In addition to other safety apparel or gear, helmets or headgear should be worn at all times for:

• Baseball and softball (when batting)
• Cycling
• Football
• Hockey
• Horseback riding
• Powered recreational vehicles
• Skateboards/scooters
• Skiing
• Snowboarding
• Wrestling

Headgear is recommended for:

• Bull riding
• Martial arts
• Pole vaulting
• Soccer
• Vintage motor sports

General Tips

• Supervise younger children at all times and do not allow use of sporting equipment or play sports unsuitable for their age
• Avoid uneven or unpaved surfaces when cycling, skateboarding or rollerblading
• Do not wear any clothing that%interfere with vision
• Do not participate in sports when ill or very tired
• Do not dive in water less than 12 feet deep or in above-ground pools
• Follow all rules at water parks and swimming pools
• Wear appropriate clothing for the sport
• Obey all traffic signals and be aware of drivers when cycling, skateboarding or rollerblading
• Perform regular safety checks of sports fields, playgrounds and equipment
• Discard and replace damaged sporting equipment or protective gear
