Using wrist supports and wrist rests can reduce the risk of repetitive strain injury when using a computer. Positioning the keyboard to keep the wrists in a neutral position is important. OSHA recommends palm and wrist supports that mimic natural curves and provide cushioning. Taking breaks every 30-60 minutes is also recommended. Consult with a doctor or physical therapist for advice on appropriate wrist supports.
Using wrist supports is one way to reduce the chance of repetitive strain injury to your wrists, especially when you use a computer frequently. Wrist supports are a good idea, as are wrist rests, which can help bring your hands into a position that will cause less injury. There are many wrist supports to choose from, and the best ones are those that meet the guidelines of the Occupational Safety and Health Administration (OSHA), the US government Department of Labor.
OSHA states that hand placement most affects who will experience repetitive strain injury. Before purchasing wrist supports, several adjustments to your workstation can help reduce strain. The more the hand has to angle up from the wrist, as in typing, the more likely it is that tension will develop.
Therefore, the keyboard should be positioned so that the wrists are in a neutral position, with the hands not angled upward. Wrist rests can help keep your fingers from typing at a much higher angle than your wrists, because it becomes a natural tendency to rest your wrists down. With a rest at the same height as the bottom of the keyboard, you get more wrist support and your fingers are at a neutral level.
OSHA recommends palm supports in the form of palm rests that are at least 1.5 cm high and that the supports should be relatively soft, providing some cushioning. OSHA suggests that supports be rounded as this mimics the natural curves of the wrists. Additionally, wrist supports are recommended for those who frequently use a mouse and should be rounded, taller supports that keep the wrist neutral.
When people refer to wrist supports, they might actually be referring to a brace-like structure that is worn. It is usually made of elastic materials but inhibits upward movement of the hands. If you find that you can move your hands above your wrists while wearing them, the support may not be sufficient.
People can strain themselves to maintain an incorrect keyboard position, which can actually hurt their wrists more than it helps. Getting advice from a doctor or physical therapist about appropriate wrist supports is helpful and will likely provide you with the best possible choices.
In addition to using wrist supports, people should take breaks after long computer sessions. Physiotherapists recommend a break every thirty minutes or every hour. This can help realign your body so you aren’t putting constant strain on your wrists. In fact, many workplaces now institute breaks or time extensions to help reduce the risk of employee injury.
