Why sitting is difficult if you have arthritis
Those impacts of sitting all day are magnified for people with arthritis. For some, it can be so bad that they have trouble holding down a job. “If you have arthritis, it makes it a lot tougher to maintain being productive and active, and it can be harder to keep a job if there isn’t some amount of flexibility,” says Dr. Kwoh.
The impacts vary a bit by the type of arthritis you have, though many overlap. Rheumatoid arthritis (RA) is an autoimmune disease marked by inflammation in the joints and other parts of the body. It causes pain, redness, swelling, and warmth, Dr. Kwoh explains. Generally, it affects small joints in the hands (knuckles, wrists) and feet. With RA, staying still for too long causes the joints to really stiffen up, and it can take a while for that to go away once you start moving again. (Here’s what you should know about using CBD for rheumatoid arthritis.)
Osteoarthritis (OA), on the other hand, is called “wear and tear” arthritis, or arthritis of old age, says Dr. Kwoh. (Here’s the difference between osteoarthritis and rheumatoid arthritis.) There’s usually some low-grade inflammation involved, too. It’s most common in weight-bearing joints, like the back, hips, and knees. It can also develop in joints that have been injured in the past, Dr. Kwoh says. It’s less common in the wrist, and when it shows up in the hands, it tends to be in the joints closest to the nails and at the base of the thumb. While some stiffness can occur, osteoarthritis is better known for causing pain when there’s too much stress on the affected joints.
While some lifestyle modifications—including regular exercise and weight loss (if your arthritis is in weight-bearing joints)—can help you manage arthritis, there are also some simple things that you can do at work to minimize arthritis-related stiffness and pain, no matter which type of arthritis you have.
Set up an ergonomic workstation
“In both types of arthritis, you really need a good ergonomic workstation,” Dr. Kwoh says. “The keyboard should be at a height where your hands are down and elbows are flexed but not elevated too high. Your shoulders should be relaxed, elbows bent at about 90 degrees, and your wrists should be flat and not bent.” Ideally, you should have a neutral neck and be able to just gaze down a bit with your eyes at the screen to avoid straining your back, neck, and shoulders. (Here’s more detailed information on how to optimize your desk setup.)
It’s OK to change things up a bit to make them most comfortable for you, though, says Lorie Y. Barker, an occupational therapist and an instructor of occupational therapy at Colorado State University in Fort Collins.
For example, you may want to push the keyboard a little away from you to open up the arms and have the elbows at a wider angle. “The best thing is to not be putting pressure on the elbows or the wrists,” Barker says. Avoid resting your wrists on the keyboard or your elbows on armrests for a long period of time. “People tend to rest on the elbow joint where the nerve is and that causes more problems.”
Putting a pillow or chair cushion behind your back can also help support the spine if you have back arthritis.
Change positions frequently throughout the day
“The bottom line is you have to move around,” says Dr. Kim. “Don’t sit all day, don’t stand all day. Moving around is best.” Every 30 minutes to an hour, change positions, even if it’s a tiny adjustment. This will help keep your joints from getting stiff or enduring too much pressure in one area or position. The key is to avoid maintaining a static posture all day long, says Barker.
