CHAPTER 77 • BASKETBALL 465

collegiate level (NCAA, 1998) and 47–56% at the
high school level. (Messina and DeLee, 1999)
•Following European professional players over two
years there were 37 surgeries (8.7%) performed on a
total of 423 injuries (Huget, 1999).



  • Nonmusculoskeletal problems

  • Cumulative data from 3 NBA seasons show 25.9% of
    reported medical problems were classified as nonath-
    letic related (Steingard, 1993).


INFECTIOUS DISEASE



  • Mononucleosis is not specifically seen in basketball
    more than other sports but must be attentively treated.
    Resulting splenomegaly and risk of splenic rupture
    (even in the absence of splenic enlargement) from
    epstein barr virus(EBV) are significant and preclude
    active participation by an infected individual. Rapid
    monospot tests can have false negatives in the first
    7–10 days so individuals with suspected EBV should
    be tested for serum antibodies, which are more sensi-
    tive in the early course. Since splenic rupture occurs
    in the first 3–4 weeks after infection, it is recom-
    mended to keep players out of activities during this
    time. Recovery can be prolonged with fatigue that
    prevents return to play for weeks or months.

  • Fungal infections are prevalent in athletes and tinea
    pedis is the most common dermatophytosis. High top
    shoes, perspiration, friction, and poor foot care con-
    tribute to recurrent problems. Drying feet, changing
    socks, absorbent powders (without corn starch), and
    over-the-counter(OTC) and prescription antifungals
    are effective treatment measures. Similar measures
    should be taken to treat tinea cruris or “jock itch”
    which is also common in athletes.

  • Upper respiratory infections(URI) are common in bas-
    ketball athletes but treatment should vary little from
    standard measures. Symptomatic treatment including
    analgesics, decongestants, and antihistamines provide
    relief for most individuals. These infections are typi-
    cally viral so antibiotics should be reserved for cases
    that fail to improve with symptomatic treatment.


CONCUSSION



  • Concussion or mild traumatic brain injury(MTBI)
    occurs in basketball from two mechanisms—player-
    to-player contact or contact with the floor. MTBI
    results from damage to the brain and functional
    deficits from rapid, strong compression, shear, or ten-
    sile forces to the head.

    • Signs and symptoms include loss of consciousness,
      headache, amnesia, dizziness, nausea, confusion, and
      visual disturbance. Individuals often have associated
      subjective complaints including difficulty concentrat-
      ing, sleep disturbance, emotional lability, behavioral
      changes, change in smell or taste, poor energy, cong-
      nitive decline, and irritability. Recovery is variable
      and often difficult to assess.

    • Mild head injury makes up more than 90% of all
      MTBI and is difficult to recognize since there is no
      loss of consciousness but a transient loss of alertness
      or a brief period of posttraumatic amnesia that may be
      difficult to recognize (Cantu, 1996).

    • The National Athletic Trainers Association injury sur-
      veillance program investigated MTBI for three years
      in high school basketball players from 114 schools.
      MTBI comprises 4.2% of injuries in males and 5.2%
      in females. Player collisions are the most likely eti-
      olgy and most of these occur in the open court, not
      under the basket (Powell, 1999).

    • Many concussion guidelines have been published
      including those by the American College of Sports
      Medicine, Dr. Robert Cantu, the American Medical
      Society for Sports Medicine, and the Colorado
      Medical Society. These guidelines generally utilize
      neurologic symptoms, sideline memory and functional
      testing, and loss of consciousness to classify concus-
      sion severity.

    • Return to play criteria is based on symptom resolu-
      tion and history of previous concussion. It is often
      challenging to evaluate concussive symptoms and
      new evidence suggests cognitive testing should be
      the main criteria for return to play decisions. Our
      understanding of concussion, treatment options, and
      recovery are changing rapidly. Established concus-
      sion guidelines are giving way to methods that uti-
      lize emerging return to play criteria based on
      cognitive and neuropsychiatric testing. This allows
      at risk players, sometimes not clinically sympto-
      matic, to be held while returning recovered players
      back to competition earlier than previously thought
      possible.




ASTHMA

•Exercise related bronchospasm is common in all
sports. Classic symptoms include shortness of breath
with chest tightness, cough, and wheezing. Symptoms
typically begin 8–10 min into moderate exercise.


  • Pulmonary function tests show a >15% drop in forced
    expiratory volume in 1 s (FEV1), >35% decrease in
    forced expiratory flow rate, >10% decrease in peak
