Tennis Elbow
(Lateral and Medial Epicondylitis)
Tennis elbow is an injury to the muscles and tendons on the
outside (lateral aspect) of the elbow that results from
overuse or repetitive stress. The narrowing of the muscle
bellies of the forearm as they merge into the tendons create
highly focused stress where they insert into the bone of the
elbow.
- Lateral epicondylitis
- Injury to the lateral aspect of the elbow is the
most common upper extremity tennis injury. Tennis elbow
is generally caused by overuse of the extensor tendons
of the forearm, particularly the extensor carpi radialis
brevis. Commonly experienced by the amateur player, this
injury is often a result of
(1) A one-handed backhand
with poor technique (the ball is hit with the front of
the shoulder up and power generated from the forearm
muscles). (2) A late forehand swing preparation with
resulting wrist snap to bring the racquet head
perpendicular to the ball. (3) While serving, the
ball is hit with full power and speed with wrist pronation (palm turned downward) and wrist snap which
increases the stress on the already taught extensor
tendons.
- Medial epicondylitis
- Medial epicondylitis is less common and
characteristically occurs with wrist flexor activity and
pronation. Medial epicondylitis can result from:(1) Late
forehand biomechanics where the player quickly snaps the
wrist to bring the racquet head forward.
(2) The
back-scratch or cocking phase when serving, which places
tremendous stress on the medial tissues of the elbow. (3)
In the right elbow of a right-handed golf swing by
throwing the club head down at the ball with the right
arm rather than pulling the club through with the left
arm and trunk (also referred to as "golfers elbow").< (4)
Improper pulling technique with certain swim
strokes, especially the backstroke (also referred to as
"swimmers elbow").
It should be kept in mind that elbow epicondylitis is not
limited to those persons playing tennis, golf, baseball or
swimming and can result from any activity that puts the
lateral or medial compartments of the elbow under similar
repetitive stress and strain (e.g., hammering, turning a
key, screw driver use, computer work, excessive hand
shaking).
General
- difficulty holding onto, pinching, or gripping
objects
- pain, stiffness, or insufficient elbow and hand
movement
- forearm muscle tightness
- insufficient forearm functional strength
- point tenderness at or near the insertion sites of
the muscles of the lateral or medial elbow

Rehabilitation - What You Can Expect
|
Epicondylitis, both medial and lateral, is a common and
often lingering pathologic condition. It is critical,
therefore, that you progress your rehabilitation only when
you experience minimal or no pain. For more on when and how
to progress, see below.
As a general guideline, the more chronic or longer you
have experienced the condition, the longer the recovery time
is to be expected (up to 8 weeks).
Rehabilitation - What should I do, when should I
do it, and how?
|
Epicondylitis often becomes a chronic problem if not cared
for properly. For this reason, it must be stressed that the
rehabilitation process should not be progressed until you
experience little or no pain at the level you are
performing. Regaining full strength and flexibility is
critical before returning to your previous level of sports
activity.
In general, the rehabilitation process can be divided
into three phases:
- PHASE 1
- Goals: decrease inflammation and pain,
promote tissue healing, and retard muscle atrophy.
During the acute stage of your injury, whether the
medial or lateral elbow is affected, follow the
RICE principle:
- Rest - this means avoiding
further overuse not absence of activity. You should
maintain as high an activity level as possible while
avoiding activities that aggravate the injury.
Absolute rest should be avoided as it encourages
muscle atrophy, deconditions tissue, and decreases
blood supply to the area, all of which is
detrimental to the healing process. Pain is the best
guide to determine the appropriate type and level of
activity.
- Ice - is recommended as long as
inflammation is present. This may mean throughout
the entire rehabilitation process and return to
sports. Ice decreases the inflammatory process slows
local metabolism and helps relieve pain and muscle
spasm.
- Compress and Elevate
if appropriate to assist venous return and minimize
swelling.
- PHASE 2
- Goals: Improve flexibility, increase
strength and endurance, increase functional activities
and return to function.
-
Stretching
Gentle stretching exercises including wrist flexion,
extension and rotation. The elbow should be extended and
not flexed to increase the amount of stretch as
required. These stretches should be held for 20-30
seconds and repeated 5-10 times, at least twice a day.
Vigorous stretching should be avoided - do not stretch
to the point of pain that reproduces your symptoms.
- Strengthening
With the elbow bent and the wrist supported perform the
following exercises:
- Wrist Extension. Place 1 lb. weight in
hand with palm facing downward (pronated); support
forearm at the edge of a table or on your knee so
that only your hand can move. Raise wrist/hand up
slowly (concentric contraction), and lower slowly
(eccentric contraction).
- Wrist Flexion. Place 1 lb. weight in
hand with palm facing upward (supinated); support
forearm at the edge of a table or on your knee so
that only your hand can move. Bend wrist up slowly
(concentric), and then lower slowly (eccentric)(similar
to exercise above).
- Combined Flexion/Extension. Attach one
end of a string to a cut broom stick or similar
device, attach the other end to a weight. In
standing, extend your arms and elbows straight out
in front of you. Roll the weight up from the ground
by turning the wrists. Flexors are worked with the
palms facing upward. Extensors are worked with the
palms facing downward.
- Forearm Pronation/Supination. Grasp
hammer (wrench, or some similar device) in hand with
forearm supported. Rotate hand to palm down
position, return to start position (hammer
perpendicular to floor), rotate to palm up position,
repeat. To increase or decrease resistance, by move
hand farther away or closer towards the head of the
hammer.
- Finger Extension. Place a rubber band
around all five finger tips. Spread fingers 25
times, repeat 3 times. If resistance is not enough,
add a second rubber band or use a rubber band of
greater thickness which will provide more
resistance.
- Ball Squeeze. Place rubber ball or
tennis ball in palm of hand, squeeze 25 times,
repeat 3 times. If pain is reproduced squeeze a
folded sponge or piece of foam.
- For all of the exercises (except combined
flexion\extension) perform 10 repetitions 3-5 times a
day. With the combined flexion/extension perform until
you feel fatigue. With all exercises use pain as your
guide - all exercises should be pain free.
- When to progress. Begin with a 1 lb. weight
and perform 3 sets of 10 repetitions. When this becomes
easy, work up to 15 repetitions. Increase the weight
only when you can complete 15 repetitions 3 times
without difficulty. The axiom "No Pain No Gain" does
NOT apply here.
- After exercising, massage across the area of
tenderness with an ice cube for about 5 minutes. You
might also try filling a paper cup half-full with water
and freeze; peel back a portion of the paper cup to
expose the ice.
- PHASE 3
- Goals: Improve muscular strength and
endurance, maintain and improve flexibility, and
gradually return to prior level of sport or high level
activity.
Continue the stretching and strengthening exercises
emphasizing the eccentric contractions of wrist flexion
and extension. In this regard, since the eccentric
contractions are movements with gravity, do not let the
weight drop too quickly; lower the weight in a
controlled fashion. With the combined wrist
flexion/extension exercise, work on increasing speed
when rolling up the string with the attached weight as
this will improve endurance.
When your symptoms are resolved and have regained
full range of motion and strength, you may gradually
increase your level of playing activity. An example of
one gradual progressive return to tennis is as follows:
| Lateral Epicondylitis |
Medial Epicondylitis |
| 15 minutes forehand only |
15 minutes backhand and lobs |
| 30 minutes forehand only |
30 minutes backhand and lobs |
| 30 minutes forehand and two handed backhand |
30 minutes backhand, lobs, forehand (no top
spin) |
| 45 minutes forehand and backhand |
45 minutes backhand, lobs, forehand |
| 45 minutes all strokes |
45 minutes all stokes |
| Serve |

Lateral counter-force bracing is believed to reduce the
magnitude of muscle contraction which in turn reduces the
degree of muscle tension in the region of muscular
attachment. The counter-force brace is essentially an
inelastic cuff that is worn around the proximal (near)
forearm (against the forearm extensors for lateral
epicondylitis and around the forearm flexors for medial
epicondylitis).
In theory, the brace constrains full muscle expansion
when the muscle contracts, diminishes muscle activity, and
therefore the force generated by the muscle. An analogy is
the fret on a guitar; when you exert pressure on a different
fret along the neck of the guitar, it changes and reduces
the tension on the guitar string above where the pressure is
exerted.
The counter-force brace can be worn beginning in Phase 2
of your rehabilitation program. However, adhere to the
following caution: do not become dependent on the
counter-force brace and gradually wean yourself off its use
during Phase 3. Counter-force bracing is a supplement to,
not a replacement for your rehabilitation program.
Using the wrong tennis racquet may have been a contributing
factor to your injury. Guidelines for racquet selection for
non-tournament players are provided below.
-
Racquet material - Graphite composites are
currently considered the best in terms of torsion and
vibration control.
-
Head size - A midsize racquet (95-110
square inches) is preferred. The popular oversized
racquets cause problems because they make the arm
susceptible to injury due to the increased torque effect
of shots hit off-center.
-
String tension - stay at the lower end of
the manufacturer's recommendation. While higher string
tensions provide improved ball control, it also
increases the torque and vibration experienced by the
arm.
-
Stringing material - synthetic nylon
(re-string every 6 months).
-
Grip size - A grip too large or too small
lessens control and promotes excessive wrist movement.
To measure an appropriate grip size for your hand see
image below.
