Is it important to have your arms properly supported while typing?
| | | | Your arms and hands get just enough blood supply to allow the muscles to work. Working with your arms unsupported against gravity will cause the muscles to demand a greater blood supply. Think of blood as fuel for your muscles. If you use up too much fuel early in the day, your muscles will run out of gas and fatigue. It is important to minimize the energy needed to work by providing upper extremity support while typing at a computer. A chair with armrests provides a sufficient amount of support. Tennis elbow is one of many problems that can result from a lack of upper extremity support while typing. |
