- Chromolyn sodium is rarely effective when used alone
and tends to be quite expensive in the required dosages.
Moderate to Severe Symptoms
- Athletes who require second-line medications should
be further evaluated. - Addition of a second medication listed above
- Addition of inhaled corticosteroid (budesonide, fluti-
casone) or beta-agonist/corticosteroid combinations
(Advair-Glaxo Wellcome).- Inhaled corticosteroid is effective in alleviating the
postexercise cough brought on by late phase inflam-
matory effects of EIA.
- Inhaled corticosteroid is effective in alleviating the
- Doping control:Care must be taken to ensure compli-
ance with doping control measures in elite level skiers. - Most asthma medications are restricted and appropri-
ate procedures for documenting their use is required.
Recently, the International Olympic Committee (IOC)
and FIS have begun requiring documented testing of
these athletes prior to the use of asthma medications. - The USADA hotline is a useful resource for any ques-
tions regarding the use of these medications (1-800-
223-0393).
COMMON MUSCULOSKELETAL PROBLEMS
SACROILIITIS
- Pathophysiology:The sacroiliac(SI) joint is a bicon-
cave articulation of the hemipelvis to the sacrum. It
has relatively small rotational motion but functions
primarily to transmit force from the lower extremity
to the spine. Sacroiliac dysfunction is the most
common cause of low back pain in the skier. - Injury can result from direct trauma associated with a
fall, but more commonly arises from repetitive load-
ing. Contributing factors in this injury include SI joint
hypermobility, excessive shear forces, and relative
core strength deficits. - Clinical features:Symptoms stem from inflammation
in the SI joint and include local pain at the SI joint that
is exacerbated with walking, running, or skiing. - The athlete will often have associated lateral hip pain
and pain at the gluteal prominance. Radicular symp-
toms are unusual and are associated with piriformis
spasm, facet irritation, or concomitant disk disease. - Examination will typically reveal the following:
Tenderness at the SI joint and relative hypomobility on
the effected side with a standing knee to chest test
•FABER test (flexion, abduction, and external rotation)
will usually elicit symptoms. Neurologic examination
is normal. - Diagnostic testing: Radiographs may demonstrate
arthrosis or degenerative disease of the lower spine.- Treatment:Pain relief strategies include oral anal-
gesics/anti-inflammatory medications, chiropractic
treatment, ice, massage, and stretching. - Long-term management aims at improving SI func-
tion through core stabilization and muscle balance
training (Thera-ball program, Pilates, or similar).
•Technique and equipment issues should also be
reviewed.
- Treatment:Pain relief strategies include oral anal-

DYSFUNCTION)/ILLIOTIBIALBANDFRICTION
SYNDROME - See detailed descriptions in chapters 60 and 61 respec-
tively.
EXERTIONALANTERIORCOMPARTMENTSYNDROME
- Pathophysiology:In cross-country skiers, exertional
compartment syndrome(ECS) typically effects the ante-
rior or lateral compartments representing injury to the
tibialis anterior or peroneus brevis muscles respectively. - ECS is precipitated by exercise induced swelling of
the soft tissue in the confined compartment leading to
ischemic pain in the effected muscle. - This is most common in skating technique where the
foot is dorsiflexed and everted during ski recovery. - This injury was very prevalent when the technique was
first introduced due to the excessive length of the ski
and relatively soft binding used with the classic stride.
As equipment has been developed specifically for the
skating technique, this has become less common. It is
now most commonly seen with the use of combination
equipment (designed for both skating and classic tech-
nique) and with poorly fitting equipment. - Clinical features:See detailed description of symp-
toms in chapters 22 and 63. - Diagnostic testing:Pre- and postexercise compart-
ment pressure testing may be helpful although it is
difficult to reproduce the specific conditions of skiing
in the laboratory (see chapter 22). - Treatment:Includes decreasing compartment inflam-
mation using anti-inflammatory medications and
improving function through a balanced stretching and
strengthening program. - Equipment modifications should be made to utilize a
skating specific boot-binding-ski system. A stiffer
binding and shorter ski may also help. - In resistant cases a surgical fasciotomy may be neces-
sary (see chapter 63).
PERONEUSTENDONINJURY
- Pathophysiology:Injury to the peroneus tendon can
occur with an acute inversion dorsiflexion injury or
