"Correct Throwing is Key to Preventing Arm and
Shoulder Injuries"
ALEXANDRIA, VA, May 26, 2000 - From the youngsters playing their
first game of tee-ball to the last team standing at the Little League
World Series in August, spring and summer baseball is a rite of passage
in schoolyards and fields across both America and the world. But in
their attempts to throw the farthest and fastest, millions of little
leaguers put themselves at major league risk of arm and shoulder
injuries.
The American Physical Therapy Association (APTA) says that the most
coveted position on the team 3/4 pitcher 3/4 can also be the most
dangerous when it comes to arm injuries. Pitchers often throw 100 balls
per game, placing substantial stress on a young arm.
"Kids sometimes mistake strength for proper pitching mechanics and
may be trading six innings of excitement for years of arm problems,"
says Marty Stajduhar, a physical therapist who treats professional
baseball players and current little leaguers.
The pitcher runs the greatest risk of injuries resulting from overuse
or improper mechanics, leading to a condition known as "little league
elbow." Little league elbow is a chronic inflammation of the growth
plate in the elbow joint that can feel like tendinitis. In his practice,
Stajduhar has seen children under 12 years old experience the
inflammation in the medial (inside) part of the elbow and children
between 13 and 16 years old are affected on the lateral (outside) part
of the elbow, similar to "tennis elbow." With continued stress, the
growth plate may separate from the joint, requiring surgery to re-attach
it.
Most little leaguers mistakenly throw with the force coming from the
arm instead of the trunk, says Stajduhar. "When a child comes to me with
little league elbow, I ask him or her to show me their batting stance. I
point out how different the torso is positioned when they're at bat and
how much power they get from their trunk by 'stepping in' to the pitch.
It surprises them when I say they should have a similar position for
pitching." His advice: "Do not stand up straight to throw. Bend at the
waist, and direct the front shoulder and hip towards the target. When
the front foot lands, get the belly button over the front knee as
quickly as possible. Then the trunk supplies the power, not the arm."
Shoulders are also in danger during a pitch. Because the shoulder is
the most mobile joint in the body, it is also the most unstable. The
four muscles surrounding the shoulder, called the rotator cuff, are
stretched during the acceleration and deceleration. Bones can shift,
leading to damaged ligaments or pinched structures within the shoulder
joint. Torn or strained rotator cuff muscles can result in permanent
damage. To reduce the risk of injury, it is important that the muscles
of the trunk and shoulder be strong, stable, and flexible.
Because children tend to be less aware of their physical limitations,
it is especially important that parents and coaches watch their children
carefully for correct throwing mechanics, while advocating proper
conditioning and pre- and post-game stretches. "Attentive parents and
coaches will maximize their child's chances of having a healthy season,"
says Stajduhar.
APTA recommends three important upper body stretches: the inferior
shoulder stretch, the posterior shoulder stretch, and the rotator cuff
stretch. Click here to view the exercises.
"Once kids understand the proper way to throw, they need to
concentrate on being in the best condition possible," Stajduhar said.
The American Physical Therapy Association is a national professional
organization representing nearly 70,000 members. Its goal is to foster
advancements in physical therapy practice, research and education.
Danny Smith, PT, OCS a physical therapist and board-certified sports
physical therapist clinical specialist, runs clinics for Little League
coaches in Tennessee. Smith recommends the following for Little
Leaguers...and their coaches.
- Above all, teach young athletes to be mindful of how their
bodies feel. Pain is the first sign of a problem, and athletes of
all ages need to pay close attention to any type of muscle twinge,
tightening, or burning sensation.
- Coaches should carefully observe their pitchers' techniques.
Success on the field may be fleeting if the pitches are ultimately
damaging a young player's shoulder.
- Conditioning and strengthening exercises are most effective
after mechanics are learned and put into action. If possible, begin
a conditioning program at least a month before the season begins. A
basic stretching regimen should be used before a player even picks
up a baseball.
- Players should start with short tosses and gradually work up to
throwing the ball a greater distance. Increasing the velocity should
be the final step.
- If the arm region is sore or tight, apply ice to the area for
10-15 minutes to help diminish the amount of blood that might
otherwise leak into the muscle. When there is microscopic tearing of
the muscle tissue, blood is leaking into the surrounding muscular
tissue, causing pain and muscle spasm. Using ice will help reduce
the pain, spasms, and inflammation associated with this condition.
