Terminology of Movement

It is important to learn the language of movement as it relates to forearm, wrist, fingers, and thumb functions. Figure 1.3-1
depicts the accepted terminology used to describe the various movements
seen and tested in the hand, wrist, and forearm. Consistent use of
these terms will allow all health care providers to easily communicate
their findings to each other. Health workers might also develop a
reasonable diagnosis and treatment plan if they note the absence of a
specific movement. Table 1.3-1 provides the
anatomic basis for movement in the upper extremity; learning it will
aid in making a diagnosis and help to establish the site and level of
an injury.

Table 1.3-2 covers the grading
of muscle strength, which helps to document the degree of disability as
a baseline. It is a useful tool in monitoring the presence or absence
of recovery.
