 Introduction

  • 14 million adolescents participate in organized sports yearly.
  • The preparticipation examination (PPE) is the most common reason for a healthy adolescent to visit their pediatrician. 
  • Should be done 4-6 weeks before the start of the sports season.
  • Sports are graded by contact level, for example:
    • High-contact/Collision: basketball, boxing, diving, field hockey, football, soccer, wrestling.
    • Moderate, Limited Contact: baseball, bicycling, cheerleading, gymnastics, skating, skiing, volleyball.
    • Low-Noncontact: badminton, crew, golf, running, swimming, tennis, track.

 

Objectives of the Exam:

  • Identify medical and musculoskeletal conditions that could make sports participation unsafe.
  • Screen for underlying illnesses through medical and family history, ROS, and PE.
  • Recognize pre-existing injury patterns from previous sports seasons and devise ways to prevent recurrences

 

Medical History

  • Refer to cardiologist prior to particpation for:
    • Feeling of faintness, weakness, or syncope during exercise.
    • Cardiac deaths comprise the majority of sports related fatalities in the US.
    • Asthma, hypoglycemia, and seizures can cause similar symptoms
  • ​Wheezing during sports:
    • ​Use of prophylactic Beta-agonist prior to participation recommended for those with exercise-induced bronchospasm
      • Easy to check PF in office- a decrease of 10-15% from baseline is suggestive of EIB.
      • ​ Incidence of exercise-induced bronchospasm (EIB) seen in 10-35% of all athletes
  •  Concussion:
    • Recent recommendations are asking for pre-participation psychologic testing to have a baseline in case there is a later concussion.  This may help dictate when an athlete may retun to participation.
  • Recent Mononucleosis:
    • Mono-induced splenomegaly can predispose to splenic rupture
    • Mono within 1 month of high- and moderate-contact sports is at risk because spleen size peaks within 3-4 weeks of onset of systemic signs of illnesd
  • Unilateral Organ:
    • Single kidney is a contraindication for high-contact sports per AAP
    • Single testicle requires mandatory protective cup.
  • Current medications:
    • Document drug use.
    • Albuterol, methylxanthines, macrolides, pseudoephedrine, illicit drugs have been linked to arrhythmias.
  • Menstrual History:
    • Screen for amenorrhea- primary or secondary.
    • Look for female athlete triad:   anorexia, amenorrhea, osteoporosis.
  • Seizure disorder:
    • Not direct contraindication if seizures are well controlled.
    • History of seizure within past 6 months should raise concern, especially for water sports.
  • Past history of injury:
    • Devise rehab protocols to prevent injuries such as chronic ankle sprains.
  • Ergogenic Aids:
    • No testing policy- 9% reported use in high school athletes.
    • Ask, "Have you ever taken a substance to enhance your athletic performance?"

Family History

Family history is more sensitive than than the physical examination in identifying conditions that may affedt participation.
 

Positive family history of:

    1. Cardiac-related death in a first-degree relative younger than 50 y/o.  Be suspicious of congenital heart disease, arrhythmia, prolonged QT syndrome, hypertrophic cardiomyopathy, and Marfan syndrome in first-degree relative.
    2. Family history of chronic disease—asthma, diabetes, epilepsy, bleeding disorders.

 

Physical Exam

1. Vital signs, height, weight, BP, HR, RR.
2. Visual- excessive thinness or obesity.
3. Skin- impetigo, molluscum, herpes, especially relevant to wrestling.
4. HEENT: visual acuity (must be 20/40 for clearance), pupils, dentition.
5. Cardiac:  History, ROS, VS, auscultation.

  • Unfortunately, majority of patients who suffer cardiac death are previously asymptomatic.
  • More than 50% of cardiac-related deaths are due to hypertrophic caridiomyopathy, which is autosomal dominant.
  • History of cardiac symptoms with exertion should be referred to cardiologist.

6. Pulmonary: Screen for asthma and EIB.
7. Abdominal:  Organomegaly and presence of unilateral organ.
8. GU: Hernia, testicular protection. 

  • Sexual maturity ratings should be used; the lower the rating, the higher risk of suffering a physeal fracture.

 

Musculoskeletal Exam

Spine:

  • Previous cervical spine injuries should prompt one to obtain screening C-spine XRAYS
  • Cervical stenosis- need MRI
  •  Rule out kyphosis and scoliosis
  • Suspect spondylolysis and spondylolithesis with pain upon extension
  • Suspicion for neoplasm with unexpected back pain
  • On exam, pain with flexion-?discogenic pain; extension? posterior element overuse, such as spondylolysis; rotational ? paraspinous muscle pain.
  • Check reflexes.

Shoulder:

  • Common for overuse syndromes (rotator cuff), esp. in overhead sports.
  • Preseason conditioning programs are helpful.

Knee:

  • Focus on history of knee pain.
  • Screen both knees for ligamentous stability.
  • ACL injury 3-4:1 in female: male.
  • Persistent knee pain with flexion and swelling, consider 40view knee series to rule-out osteochondritis dessicans of the femoral condyle.

Ankle:

  • Most commonly affected joint.
  • Related to repetitive sprain and subsequent instability.
  • Preventive strengthening programs should be encouraged.

 

Conditioning Programs:

  • Weight training and aerobic conditioning.
  • Weight training should focus on high repetition and low resistance.
  • Because of the potential risk of apophyseal avulsion fracture, preadolescents should never undertake power lifting.  Strength training is safe.
