To EDIT Sensory or Motor Stimulation Settings

NOTE:

The sensory and motor stimulation screens have a similar look,

feel and functionality (see figures 11 and 12). The values associated with
each stimulation mode differ, but the setting types are the same. Only
the sensory stimulation screens will be illustrated to explain how to edit
stimulation setting values.
