About Repetitive Strain Injury
Because your comfort and safety are our primary concern, we strongly recommend
that you use the Infiniium oscilloscope in accordance with established ergonomic
principles and recommendations. Scientific literature suggests that there may be a
relationship between injury to soft tissues—especially in the hands and arms—and
prolonged improper use of keyboards or other equipment requiring repeated
motions of the hands and forearms. This literature also suggests that many other
risk factors may increase the chance of such injury, commonly called Repetitive
Strain Injury.
What is RSI?
Repetitive Strain Injury (RSI—also known as cumulative trauma disorder or
repetitive motion injury) is a type of injury where soft tissues in the body, such as
muscles, nerves, or tendons, become irritated or inflamed. RSI has been a reported
problem for those who perform repetitive tasks such as assembly line work,
meatpacking, sewing, playing musical instruments, and computer work. RSI also
has been observed in those who frequently engage in activities such as carpentry,
knitting, housework, gardening, tennis, windsurfing, and lifting children.
What causes RSI?
The specific causes of RSI have not been established. Nevertheless, the incidence
of RSI has been associated with a variety of risk factors, including:
• Too many uninterrupted repetitions of an activity or motion
• Performing an activity in an awkward or unnatural posture
• Maintaining static posture for prolonged periods
• Failing to take frequent short breaks
• Other environmental and psychosocial factors
In addition, there have been reports associating the occurrence of RSI with the use
of keyboards, mice, and other input devices. Also, certain medical conditions, such
as rheumatoid arthritis, obesity, and diabetes, may predispose some people to this
type of injury.
What if I experience discomfort?
If you are experiencing any discomfort, seek professional medical advice
immediately. Typically, the earlier a problem is diagnosed and treated, the easier it
is to resolve.
