Abstract: Computers
are ubiquitous in daily life; they have become a required tool for students and many
professions. Computer input devices such as mice and keyboards are known risk factors
for upper extremity muscle skeletal disorders, and previous research has suggested that
some device designs are safer than others, and women experience a higher rate of injury
which may be due to their ... read moresmaller anthropometry. This study used electromyography to
examine the relationship among three different computer pointing devices in women across
an anthropometric spectrum. In addition, the devices were tested in both the normal
location to the right of the keyboard and at the center. Subjects were asked qualitative
questions (yes/no and likert) about their experiences with the devices. The results
showed a significant difference in measured and reported outcomes due to the different
devices, but location and anthropometric measurements did not have a significant
effect.
