The Effect of Dynamic Stabilizers for Valgus Stability of the Elbow in Professional Baseball Players

This is a study of the muscle stabilizers of the elbow with respect to the prevention of
Ulnar Collateral Ligament (UCL) injuries in pitchers. Pitchers are assessed at spring
training and end of season for approximately 5 years. Pronator, flexor digitoum superficialis
(FDS), and wrist flexion strength will be measured and correlated with upper extremity
injuries and time missed from pitching. The investigators will also be measuring loss of
strength over the season. The goal is to learn whether strength in these muscles prevents UCL
injuries and finally whether these muscles can be strengthened to avoid such injuries.

The goal of this study is to assess whether the strengths of the secondary muscular
stabilizers toward valgus stress at the elbow, the wrist flexors, flexor digitorum
superficialis, and pronator teres emanating from the medial epicondyle, affect the incidence
of ulnar collateral ligament injuries of the elbows in pitchers. Pitchers in the minor
leagues of a single professional baseball club will have the strength of these secondary
muscular stabilizers assessed and then correlated to ulnar collateral ligament injuries and
time missed from baseball season and subsequent seasons. A secondary goal is to assess
whether strengthening exercises targeted toward these muscular stabilizers of the elbow can
decrease the incidence of ulnar collateral ligament injuries in young baseball pitchers. This
could impact the field by changing the emphasis from reconstruction and rehabilitation of
ulnar collateral ligament injuries to prevention.

Inclusion Criteria:

- Pitchers that are currently on a minor league baseball team.

Exclusion Criteria:

- Pitchers that currently have upper extremity injuries or are in active rehab for upper
extremity injury.
