Achilles Tendonitis: Overview
Achilles tendonitis is inflammation and/or degeneration of the Achilles
tendon. The Achilles tendon connects the calf muscles to the heel bone.
The Achilles tendon can become irritated for several reasons including:
increasing your speed or running distance too quickly
suddenly adding strenuous hills or stair climbing to your exercise routine
doing too much too soon after taking time away from exercising
a sudden or violent contraction of the calf muscles, such as during an
all-out sprint
overuse injury
lack of flexibility of the calf muscles
Risk factors that increase your chances of getting Achilles tendonitis include:
improper footwear
improper warm-up for your activity
inflexibility of the calf muscles
improper cool down
Diagnosis
Symptoms may include:
tenderness an inch and a half above the point where the Achilles tendon
attaches to the heel bone (noticeable in the morning upon rising)
stiffness that gradually eases as the tendon is warmed-up
pain after activity that gradually worsens
radiating or localized pain along the tendon during and/or after running
swelling
The doctor will ask about your symptoms, exercise habits, and perform
a physical exam. He or she may also perform the following tests:
x-rays — to see if there is calcium in the tendon
magnetic resonance imaging (MRI) scan — to view areas of damage
to the tendon
Treatment Options
Treatment includes:
rest
Take a break from the activity that caused the tendonitis. Switch to an
activity such as swimming that doesn't put stress on the tendon.
orthoses
You may be advised to wear a heel pad or shoe insert that will place your
foot in the correct position for walking and running.
physical therapy
You may be directed to undergo physical therapy such as stretching, massage,
ultrasound, and strengthening exercises.
medications
Take nonsteroidal anti-inflammatory drugs (NSAID) to ease the pain and decrease
inflammation.
Prevention
To decrease your chances of experiencing Achilles tendonitis:
Take the time to warm-up and cooldown properly.
Wear appropriate footwear for your sport.
Do not use shoes beyond the recommended duration. This duration
will depend on:
- how frequently you exercise
- the surface on which you exercise
- the conditions in which you exercise
Gradually add hill work, stairs, speed, and distance to your exercise
routine.
Stretch and strengthen the calf muscles regularly.
How Athletes Can Prevent Achilles Tendinitis
Achilles tendonitis is best prevented by stretching your calf muscles
and Achilles tendons before activities. If you have tight Achilles tendons
or calf muscles, it is a good idea to stretch these twice a day whether
or not you are doing any sports activities that day. If you have a tendency
to get Achilles tendonitis, it is a good idea to avoid doing a lot of
uphill running.
Here are six steps to reduce your risk of Achilles tendonitis:
Choose your running shoes carefully. They should provide sufficient cushion
for the heel strike. Using a prescribed orthotic to change the position
of a poorly aligned heel bone may also help. Perhaps the best precaution
is to know your limits and to follow a sensible program when you exercise.
In addition to custom-fitted orthotics, all runners should be encouraged
to wear well-designed shoes that provide good heel stability with a small
amount of additional heel lift. This helps to prevent Achilles tendon problems
and is especially important in athletes running more than a few miles at
a time.
Walk and stretch to warm up gradually before running. It’s better
to spend few minutes warming up than to spend months on the sidelines with
a ruptured Achilles tendon.
Focus on stretching and strengthening the muscles in the calf.
Increase your running distance and your speed gradually, in increments
no greater than 10 percent a week.
Avoid unaccustomed strenuous sprinting, such as hill running.
Cool down properly by stretching after exercise.
Improving Sports Performance
The key to improving sports performance after a diagnosis of Achilles
tendonitis is a proper rehabilitation program, and adhering to some of
those same principles after the injury is gone.
The single most important aspect of improving performance is stretching
before and after you step onto the field, court, ice, or golf course.
Benefits derived from stretching include:
increased physical efficiency and performance
decreased risk of injury
increased blood supply and nutrients to joint structures
increased coordination
improved muscular balance and postural awareness
decreased risk of lower-back pain
reduced stress
enhanced enjoyment
Rehabilitation for Achilles tendonitis often includes the following:
Reduce activity during the acute phase.
Ice injury multiple times per day (place foot/ankle in bucket of ice
water).
Use 1/8" felt pad heel lifts in both shoes until symptoms are gone.
Perform gentle exercises, such as hopping on toes or jump roping,
to build elasticity in the muscle and tendon. Start minimally, and only
after pain is gone.
Use anti-inflammatory medications such as ibuprofen to reduce inflammation
and speed up recovery.
The major objectives of rehabilitation from Achilles tendonitis are to improve
the elasticity of the calf muscle and to gradually increase pain-free range
of motion at the ankle. Exercises to achieve these goals include:
Gastrocnemius stretch
Stand in front of a wall and flatten your palms on the wall, elbows extended.
Bend elbows and lean into the wall while keeping back and knees straight
and feet flat on the floor. Lean as far into the wall as first significant
pain allows, attempting ultimately to rest forehead on the wall. Hold this
position for 10 to 20 seconds, then extend elbows while maintaining hand
contact with the wall. Rest for five to 10 seconds. Perform this procedure
10 times at least three times daily. While this exercise can be modified
to stretch only the injured side, doing both sides is recommended to protect
the uninvolved side from injury while rehabilitating the injured tendon.
Soleus stretch
Stand in front of a wall and flatten your palms on the wall, elbows extended.
Slightly flex knees but keep back straight. Feet must remain flat on the
floor or ground. Lean as far into the wall as first significant pain permits
and hold this position for 10 to 20 seconds. Extend the elbows while maintaining
hand contact with the wall. Rest for five to 10 seconds. Perform this cycle
10 times at least three times daily. While this exercise can be modified
to stretch only the injured side, doing both sides is recommended to protect
the uninvolved side from injury while rehabilitating the injured tendon.
Foot flexion
Sit on the floor, extending the injured-side leg and flexing the opposite
leg at the knee. Loop a towel under the instep of the injured-side foot
while holding an end of the towel in each hand. Gently draw back on the
foot with the towel until first pain intervenes. Hold this position for
10 seconds. Relax the arms and the foot and rest for 10 seconds. Do this
routine 10 times at least three times daily. Perform the same routine with
the uninjured side to protect it from injury.
Double leg raises
Stand erect with hands resting lightly on a chair back, table, or other
supporting structure. Slowly raise up on the toes to the point of first
pain at the injury site. Hold this position for 10 to 15 seconds, then return
to start position. Rest for five seconds. Perform this sequence 10 times
at least three times daily. This exercise both rehabilitates the injured
tendon and helps protect the uninjured one.
Single leg raises
Stand erect with one hand resting lightly on a supporting structure placed
beside you. Flex the knee farthest from the supporting structure and raise
the heel backward so that body weight is on the opposite leg. Slowly raise
up on the toes of the weight-bearing leg. In the instance of the injured
side, raise up only to the point of first pain. Hold this position for 10
to 15 seconds, then return to start position and rest for five seconds.
Perform this cycle 10 times. Reverse the position of the legs and do the
same sequence as described for the first exercised leg. Perform this series
at least three times daily. This exercise both rehabilitates the injured
tendon and helps protect the uninjured one.
Attempt exercise 5 only after you can do exercise 4 through the full range
of motion without significant pain. When you can do exercise 5 effortlessly
and without pain, add resistance by holding a one- or two-pound weight in
each hand. As strength builds, increase resistance in two- to three-pound
increments for each hand.
Alternative exercises
During the period when normal training should be avoided, alternative exercises
may be used. These activities should not require any actions that create
or intensify pain at the site of injury. They include:
swimming
water running
stationary bicycle (add resistance gradually from one session to
the next, as pain allows).
When can I return to my sport or activity?
The goal of rehabilitation is to return you to your sport or activity as
soon as is safely possible. If you return too soon you may worsen your injury,
which could lead to permanent damage. Everyone recovers from injury at a
different rate. Return to your activity is determined by how soon your Achilles
tendon area recovers, not by how many days or weeks it has been since your
injury occurred.
You may safely return to your sport or activity when, starting from the
top of the list and progressing to the end, each of the following is true:
You have full range of motion in the injured leg compared to the uninjured
leg.
You have full strength of the injured leg compared to the uninjured leg.
You can jog straight ahead without pain or limping.
You can sprint straight ahead without pain or limping.
You can do 45-degree cuts, first at half-speed, then at full-speed.
You can do 20-yard figures-of-eight, first at half-speed, then at full-speed.
You can do 90-degree cuts, first at half-speed, then at full-speed.
You can do 10-yard figures-of-eight, first at half-speed, then at full-speed.
You can jump on both legs without pain and you can jump on the injured
leg without pain.
How long will the effects of the injury last?
With proper rehabilitation, a first occurrence diagnosed and treated in
its early stages usually lasts two weeks. If the injury has recurred several
times, full recovery may take as long as six weeks.
Frequent episodes of Achilles tendonitis may result in formation of calcium
deposits in the tendon. Such a complication may require surgical treatment;
full recovery under such circumstances can take months.
