What do all of these activities have
in common?
They all involve repetitive motions of the
muscles of the forearm and elbow.
Inflammation of the tendons connected to
these muscles can result from overuse.
This inflammation is called “tennis elbow”
and can be treated with a wrist band.
Muscles of the forearm
