Introduction

Sports preparticipation physical exams (or preparticipation physical exams [PPEs]) are clinical exams used to evaluate athletes for injuries, illnesses, or other conditions that might increase the risk of harm to themselves or others when participating in sports.​​​[1]​​[2] [3] [4] American Medical Society for Sports Medicine: preparticipation physical evaluation history form​ Although the PPE is often considered a screening tool, it can also be used to evaluate the suitability of athletes with known conditions in order for them to participate in a particular athletic endeavor.
A PPE is a legal or administrative requirement for many competitive athletes in the US.[5]​ It can be an excellent vehicle for discussing health promotion and maintenance issues with young athletes. However, there is great variability in the way PPEs are performed and little objective data demonstrating that it leads to improved health outcomes.[1]​
Adding a screening ECG to a history and physical increases the likelihood of detecting potentially life-threatening cardiovascular conditions, and has been associated with a decrease in the rate of sudden cardiac death in athletes in Italy.[6] [7] [8] [9]​​​ However, it is debatable whether implementing standard ECG screening in PPEs across the US would show similar benefit and the debate on augmented cardiac screening continues.[5] [10] [11] [12] [13] [14] [15]​​​ There is a growing body of evidence suggesting possible benefit from augmented screening,​​ with a study demonstrating higher rates of ECG abnormalities in young males of black African descent.[16] [17]​​​​[18] Possibly legal and social pressures may result in a change of attitude in the US regarding this issue. However, the costs, ramifications of false positives, and lack of appropriate health system infrastructure to manage the athletes involved make it difficult to apply in the US, and these issues are likely to prevent widespread adoption of an Italian-style program in the near future.[19] The American Heart Association recommendations remain unchanged on this issue. While recognizing the limitations of the standard history and physical PPE, the AHA does not recommend routine augmented screening with ECG or other cardiovascular testing as part of the PPE at present, and instead continues to recommend the 14-point cardiovascular history and physical exam.[1] [20]​​​[21]
Despite lack of objective data, the PPE may be an excellent vehicle for screening athletes for high-risk behaviors and medical conditions that would otherwise have a profound effect on their lifelong health, if not directly on their short-term athletic performance.
Although estimates vary, studies find that only a small percentage of athletes (<1%) are denied clearance to participate.[22]
The American College of Cardiology has produced a list of key points concerning cardiovascular care of college athletes.American College of Cardiology: cardiovascular care of college student-athletes

Objectives of examination

The overriding goal of the PPE is to promote and support the health, safety, and well-being of the athlete. According to the PPE Working Group, there are 3 general objectives:[1]
  • To determine the overall physical and psychological health of the athlete

  • To detect potentially life-threatening or disabling conditions that may predispose the athlete to illness or injury, including risk of sudden cardiac arrest and other conditions

  • To serve as an entry point into the healthcare system for those without a medical home or primary care physician.

Timing and frequency

Each year, an estimated 30 million young athletes under the age of 18 undergo a preparticipation physical exam (PPE) to qualify for sports involvement.[23] It is generally recommended to be performed at least 6 weeks in advance of the athlete beginning sports participation.[24]​ This allows time for follow-up examinations, diagnostic testing, or completion of a rehabilitation program if required.
The suggested frequency of the PPE varies. The National Collegiate Athletic Association recommends that athletes undergo a comprehensive PPE upon entry into a collegiate athletic program, with additional PPEs only warranted by an updated history or change in health status.[5]​ For student athletes in secondary education, the PPE Working Group recommends a comprehensive examination upon entry to high school, repeated every 2 years in younger athletes and every 2 to 3 years in older athletes.[1]​ An annual update should be performed only as needed to address areas of concern and should include measurement of height, weight, and blood pressure, along with a comprehensive history and focused evaluation of any problems that are identified.[1] [24]

History

It has been estimated that a thorough history identifies up to 88% of problems affecting athletes.[1]​ The PPE Working Group has developed a comprehensive history form designed to identify the issues of greatest concern in the young athlete.[1] [25]​​ The form also encourages physicians to consider asking additional questions on more sensitive issues, such as mental health, substance abuse, and high-risk behaviors.[1] [25]
In addition to standard history-taking questions, special attention should be given to the personal and family history questions recommended by the American Heart Association (AHA).[26] It is designed (in combination with physical exam elements) to identify underlying cardiovascular disease and those at increased risk for sudden cardiac death:[1]
1. Personal history
  • Chest pain/discomfort/tightness/pressure related to exertion

  • Unexplained syncope/near syncope

  • Excessive and unexplained dyspnea/fatigue or palpitations associated with exercise

  • Prior recognition of a heart murmur

  • Elevated systemic blood pressure

  • Prior restriction from participation in sports

  • Prior testing for the heart, ordered by a physician.

2. Family history
  • Premature death (sudden and unexpected, or otherwise) before 50 years of age attributable to heart disease in 1 or more relatives

  • Disability from heart disease in close relative

  • Hypertrophic or dilated cardiomyopathy, long QT syndrome or other ion channelopathies, Marfan syndrome, or clinically significant arrhythmias; specific knowledge of genetic cardiac conditions in family members.

More detailed questioning should generally be pursued when history suggests a potential underlying disorder. For example, a female cross-country runner with a history of multiple stress fractures might be sensitively questioned about the possibility of an eating disorder, female athlete triad (common in women competing in sports that emphasize a low body weight; an interaction of amenorrhea, osteoporosis, and disordered eating), and training errors. Sport-specific questioning may also be useful.[27] [28] For example, athletes involved with contact sports might be questioned about prior head and neck injuries, and their sequelae. Wrestlers might be asked about current or previous skin infections, such as herpes gladiatorum, tinea, and MRSA infections. Although this approach seems logical, it has not yet been shown to improve outcomes.
Young children and older people require special consideration during a PPE. For young children, emphasis is given to assessing growth and developmental milestones, assessing physical and emotional/psychological maturity, and providing a targeted evaluation and preventive strategy for age-specific problems such as apophysitis and growth-plate injuries.
For older athletes, the evaluation is focused on the risk for coronary artery disease due to age. Postmenopausal women and older men, especially those who have been on prolonged courses of steroids or have other risk factors, need to be evaluated for osteopenia/osteoporosis. Other medical issues associated with aging similarly need to be screened for, such as osteoarthritis, degenerative disk disease, impaired balance, and poor vision and hearing.

Physical examination

A physical exam focuses on assessing overall body morphology (e.g., identifying features of Marfan syndrome), measuring blood pressure, and evaluating the cardiovascular system. Sport-specific orthopedic evaluation should be added to the general orthopedic screen as appropriate. Functional evaluation of proprioception and dynamic stability should be performed in athletes involved in sports such as gymnastics, soccer, or basketball, where suboptimal proprioception is associated with a high risk of injury. A thorough neurologic exam is especially important in athletes involved in contact sports (e.g., football, soccer). Evaluation of lower extremity biomechanics and gait may be useful in athletes who often run and/or jump (e.g., football, basketball, cross-country). It remains to be seen whether or not standardized augmented screening involving ECG or other modalities will prove to be practical on a wide scale in the US.
In expert hands, a thorough physical exam can identify many serious conditions that place the athlete or others at increased risk of harm. The exam may include:
1. Injury identification
  • The most easily identifiable conditions include orthopedic problems, such as dynamic instability of the shoulders, knees, and ankles. Chronic injuries to the fingers, wrists, feet, and toes are often noticed during a PPE. They may not be limiting the athlete at the time of the examination and so may have gone previously undetected. However, timely diagnosis and proper treatment may have long-term benefits for these injuries (e.g., chronic nonunion of scaphoid fracture, scapholunate instability, or ulnar collateral ligament tear of the first metacarpophalangeal joint).

  • The examiner should note tell-tale scars, which may indicate previous surgeries or injuries that the athlete may not be aware of or may not wish to disclose.

2. Risk assessment of existing injury
  • The impact a particular injury may have on an athlete will vary with the sport involved. For example, a basketball forward with an unstable knee due to a torn anterior cruciate ligament is at risk of recurrent instability episodes and further knee damage. However, a crew athlete with the same injury may be able to continue rowing, perhaps with some modifications, without incurring significantly increased risk for further knee damage. Thus, while a comprehensive physical exam is necessary for all athletes, the orthopedic exam should be focused towards the particular demands of the athlete's sport.

3. Cardiac assessment
  • The AHA recommends that a cardiac PPE physical exam should include:[1] [21]​
    • Auscultation for heart murmurs (to be examined both in supine and standing positions)

    • Simultaneous palpation of radial and femoral pulses to evaluate for aortic coarctation (to detect radiofemoral delay)

    • Examination for the physical features of Marfan syndrome, which can cause a variety of cardiac abnormalities including mitral valve prolapse, mitral regurgitation, dilation of the aortic root, aortic regurgitation, aortic aneurysm and aortic dissection. Physical features include: arm span greater than height; chest wall deformities; kyphoscoliosis; high-arched palate; hyperextensible joints; murmur of aortic regurgitation; murmur of mitral regurgitation; myopia (nearsightedness); and ectopia lentis (displacement or malposition of the crystalline lens of the eye)

    • Brachial artery blood pressure measurement (sitting position).

  • The AHA, while recognizing the limitations of the standard history and physical PPE, does not recommend routine augmented screening with ECG or other cardiovascular testing as part of the PPE at present.[21]

  • A systolic murmur that increases with Valsalva maneuver and decreases with squatting should make the examiner suspicious of hypertrophic cardiomyopathy.

4. Absence of paired organ
  • For example: blindness in 1 eye, absent testicle. This may not be highlighted by history taking and needs to be specifically assessed during the physical exam.

5. Dental assessment
  • This is an extremely important element of a PPE. Many athletes who have not had access to routine dental care and do not practice regular dental hygiene may have serious gingival and periodontal disease. Implications can range from poorly fitting or uncomfortable mouthguards (which may not be worn), and missed practices and games because of pain, to the need for urgent dental procedures due to infection, abscess formation, and other complications.
