One Short, Brisk Walk a Day May Keep Arthritis at Bay

One Short, Brisk Walk a Day May Keep Arthritis at Bay

MONDAY, April 1, 2019 (HealthDay News) — Less than 10 minutes a day of brisk walking can help prevent disability in people with arthritis pain in their knee, hip, ankle or foot, researchers report.

Just one hour a week of brisk physical activity “is less than 10 minutes a day for people to maintain their independence. It’s very doable,” said lead study author Dorothy Dunlop. She’s a professor of preventive medicine at Northwestern University’s Feinberg School of Medicine in Chicago.

“This minimum threshold may motivate inactive older adults to begin their path toward a physically active lifestyle with the wide range of health benefits promoted by physical activity,” Dunlop added in a university news release.

She and her team analyzed four years of data from more than 1,500 older adults in Baltimore, Pittsburgh, Columbus, Ohio, and Pawtucket, R.I., who had pain, aching or stiffness in their lower joints from osteoarthritis but were initially free of disability.

The participants’ levels of physical activity were monitored using a wearable device.

An hour a week of moderate-to-vigorous physical activity reduced their risk of disability, the study found. Specifically, the activity reduced the risk of walking too slowly to safely cross a street by 85 percent, and their risk of not being able to do daily living activities — for example, morning routine tasks such as walking across a room, bathing and dressing — by nearly 45 percent.

By the end of the four years, 24 percent of participants who did not get a weekly hour of brisk physical activity were walking too slowly to safely cross the street, and 23 percent had difficulty performing their morning routines, according to the study.

About 14 million older Americans have symptomatic knee osteoarthritis, the most common type of osteoarthritis. About 2 in 5 people with osteoarthritis — most of whom have it in their lower joints — develop disability.

Federal guidelines recommend low-impact physical activity for older adults with arthritis, and recommend that older adults do at least 2.5 hours a week of moderate-intensity activity.

But that amount of activity can be too much for inactive older adults with lower extremity pain, according to Dunlop.

“We hope this new public health finding will motivate an intermediate physical activity goal,” she said. “One hour a week is a stepping stone for people who are currently inactive. People can start to work toward that.”

The study was published April 1 in the American Journal of Preventive Medicine.

Is Your Hand Pain Arthritis, Carpal Tunnel or Something Else?

Is Your Hand Pain Arthritis, Carpal Tunnel or Something Else?

FRIDAY, March 1, 2019 (HealthDay News) — You use your hands nearly every minute of the day, so any time they hurt it’s important to find out why.

Certain conditions can affect people who do the same hand movements for hours every day. Repetitive strain injury can cause pain in muscles, nerves and tendons. Carpal tunnel syndrome swelling compresses a key nerve. The lesser known de Quervain’s tenosynovitis typically affects tendons on the inner sides of the wrist.

An autoimmune disease like rheumatoid arthritis often causes joint pain. Without treatment, it can lead to deformities in your hands. The wrist and finger joints are common targets of osteoarthritis, which occurs over time from normal wear-and-tear.

Treatment might start with an over-the-counter or prescription NSAID to temporarily relieve pain, but their long-term use has been linked to side effects such as liver or kidney damage and elevated heart attack risk.

Stronger medications may be needed to stop a degenerative disease like rheumatoid arthritis. Corticosteroid injections are an occasional option to reduce inflammation. Heat can ease stiffness while a cold pack can relieve soreness. If you have a chronic condition, an occupational therapist can teach you how to limit stress on joints when using your hands. During a flare, he or she might suggest a splint to stabilize your hand.

Sometimes surgery is needed. Dupuytren’s contracture, a thickening under the skin on the palm of the hand, can develop into firm lumps that cause fingers to bend inward. Unless lumps are removed early, it may be impossible to straighten fingers later on. If other options don’t help carpal tunnel and de Quervain’s, surgery might be the answer.

Many conditions worsen without appropriate treatment, so don’t delay in seeing your doctor or a hand specialist.

Brisk Walks May Help, Not Harm, Arthritic Knees

Brisk Walks May Help, Not Harm, Arthritic Knees

If you suffer from knee arthritis and worry that walking will only worsen your damaged joint, a new study suggests you put your fears aside, slip on some sneakers, and take a brief but brisk walk.

The researchers estimated that if older adults with the condition added just 5 minutes of brisk walking to their day, their odds of needing knee replacement surgery could dip by 16 percent.

On the other hand, light walking — akin to a “stroll” — may have no impact, said lead researcher Hiral Master, a Ph.D. candidate in biomechanics and movement sciences at the University of Delaware.

Her team reached those conclusions by digging into data from over 1,800 older adults with knee arthritis who wore portable devices that tracked their walking intensities for at least four days.

Over the next five years, 6 percent of the participants had total knee replacement surgery.

The researchers used the data on people’s walking habits to examine the effects of replacing “non-walking” time with time spent walking at different intensities. The findings showed that substituting just 5 minutes of down time with moderate-to-high intensity walking was linked to a 16 percent decline in the odds of needing knee replacement surgery.

The study authors defined “moderate-to-high” intensity as more than 100 steps per minute. In laymen’s terms, Master said, that’s a “brisk” walk that gets your heart rate up — not a stroll around the block.

The findings were presented Saturday at the American College of Rheumatology’s annual meeting, in Chicago. Such research should be considered preliminary until published in a peer-reviewed journal.

Knee osteoarthritis develops when the cartilage cushioning the joint gradually breaks down, which can eventually result in bone scraping on bone.

The condition is common among middle-aged and older Americans. According to the Arthritis Foundation, up to 13.5 percent of men and 19 percent of women aged 45 and older have knee arthritis that’s severe enough to cause pain and other symptoms.

And those patients often wonder whether walking is good or bad for their arthritic joints, said Dr. Paul Sufka, a rheumatologist at the University of Minnesota, in Minneapolis.

“They often ask whether they should minimize their activity, keep doing what they’re doing, or intensify,” said Sufka, who is also with the American College of Rheumatology’s communications committee.

“The general advice we give to patients is to stay active,” Sufka said. But, he added, the truth is there is too little evidence to give patients definitive recommendations.

The new findings do not prove that brisk walking directly lowers the risk of needing knee replacement surgery, Sufka noted.

But, “this gives us some useful information to bring to the discussion,” he added.

Overall, Sufka said, research does suggest it’s better for people with knee arthritis to be active rather than sedentary. And that’s not just for the sake of their knees. Physical activity has a range of health benefits, including lower risks of heart attack and stroke.

Master agreed, and pointed out that exercise can help arthritis patients’ mental well-being, as well as physical.

And it doesn’t take a huge lifestyle change, she explained. The new findings suggest people can benefit from adding a short, brisk walk to their day.

In fact, Sufka said, such incremental shifts may be best.

“The best exercise program is the one you can actually stick with,” he said. “If right now, you’re walking around the block every day, what would be 5 percent or 10 percent more than that? You can gradually build from where you are.”

And what if walking is painful? That’s a tricky question, Sufka acknowledged. Some patients might benefit from physical therapy rather than only exercising on their own, he said.

Beyond aerobic exercise like walking, strengthening exercises for the leg muscles supporting the knees can also be helpful, he suggested.

Secondhand Smoke Exposure as Kids Tied to Women’s Arthritis

Secondhand Smoke Exposure as Kids Tied to Women’s Arthritis

Women who were regularly exposed to secondhand smoke as children might be at slightly increased risk of rheumatoid arthritis, a new study hints.

Rheumatoid arthritis is an autoimmune disease in which the immune system mistakenly attacks the lining of the joints. Researchers believe that a mix of genes and certain environmental factors conspire to cause the disease. And a number of studies have linked smoking to a heightened risk of RA.

The new study, published Aug. 14 in the journal Rheumatology, looked at whether childhood exposure to secondhand smoke might be a risk factor for RA, too.

The answer, researchers found, is “maybe.”

Among more than 71,000 French women followed for two decades, those exposed to secondhand smoke as kids were at somewhat higher risk of rheumatoid arthritis, versus other women. That was true of women who currently smoked, and those who’d never smoked.

But those differences were not quite significant in statistical terms. That means the association between secondhand smoke and RA risk could be a chance finding.

So while the results are “provocative,” further research is necessary, one U.S. expert said.

“It’s hard to definitively say from the data what role secondhand smoke exposure in childhood plays in RA development,” said Dr. Tamar Rubinstein, a pediatric rheumatologist at Children’s Hospital at Montefiore in New York City.

Rubinstein, who is also a member of the American College of Rheumatology, was not involved in the study.

She called the findings “interesting,” and noted that there is a “growing” body of research finding links between childhood health and environmental exposures and the risks of disease later in life.

Plus, Rubinstein said, it’s biologically plausible that secondhand smoke exposure in childhood could contribute to rheumatoid arthritis later in life.

As the study authors explain it, secondhand smoke may affect immune system development in a way that makes RA more likely to develop — particularly in kids who are genetically susceptible to the arthritic disease.

Future studies should look at whether the relationship between RA and childhood smoke exposure is stronger in people who carry RA-linked genes, according to lead researcher Dr. Marie-Christine Boutron-Ruault, from the Gustave Roussy Institute in Villejuif, France.

For now, the findings “highlight the importance of children — especially those with a family history of this form of arthritis — avoiding secondhand smoke,” Boutron-Ruault said in a news release from the journal.

The findings are based on 71,248 middle-aged women who were followed for over 20 years. During that time, 371 women were diagnosed with rheumatoid arthritis.

In line with past studies, smokers showed a higher RA risk. Women who had ever smoked, but had no childhood exposure to secondhand smoke, were 38 percent more likely to develop RA than lifelong nonsmokers.

The risk appeared somewhat higher among smokers who were regularly exposed to tobacco smoke as kids. They were 67 percent more likely to develop RA than nonsmokers were.

However, the difference between smokers who were or were not exposed to smoking as kids was not statistically significant.

There was a similar pattern among women who’d never smoked: If they were regularly exposed to smokers as children, their risk of RA was 43 percent higher.

But again, that finding was just shy of statistical significance. And only an association was seen, not a cause-and-effect link.

“That doesn’t mean that there isn’t an association in reality,” Rubinstein said. “But it suggests we need to study this further to better understand it.”
