Can Exercise Help You Tolerate Pain?

New York Times health blogger Gretchen Reynolds shares the results of a new study indicating that regular exercise may alter how a person experiences pain. The longer we continue to work out, the new findings suggest, the greater our tolerance for discomfort can grow.

Scientists have known that strenuous exercise briefly and acutely dulls pain. As muscles begin to ache during a prolonged workout, scientists have found, the body typically releases natural opiates, such as endorphins, and other substances that can slightly dampen the discomfort. This effect, which scientists refer to as exercise-induced buy avodart uk hypoalgesia, usually begins during the workout and lingers for perhaps 20 or 30 minutes afterward.

Pain threshold is the point at which we start to feel pain. Pain tolerance is the amount of time that we can withstand the pain, before we cease doing whatever is causing it. The study found that volunteers who exercised had no change to their pain threshold but did have increased pain tolerance.

According to the lead researcher on the study, the findings “could be meaningful for people struggling with chronic pain.”

6,000 Steps Per Day May Be Enough for Those With Knee OA

Researchers from Boston University have found that walking reduces the risk of functional limitation associated with knee osteoarthritis (OA). The study, in part funded by the NIH (National Institutes of Health), was just published in Arthritis Care & Research. The researchers measured the daily steps taken by nearly 2,000 people with—or at risk for—knee OA. All participants were part of the Multicenter Osteoarthritis Study; each person had his or her walking measured for seven days and their functional limitation avodart online evaluated two years later.

Bottom line: Dr. Daniel White said, ” … despite the common popular goal of walking 10,000 steps per day, our study finds only 6,000 steps are necessary to realize benefits. We encourage those with or at risk of knee OA to walk at least 3,000 or more steps each day, and ultimately progress to 6,000 steps daily to minimize the risk of developing difficulty with mobility.”

Osteoarthritis Patients are Better Off Walking

Orthopedics This Week reports on a study finding that osteoarthritis patients benefit from walking and should not fear that walking might cause increased damage to their joints. “People with osteoarthritis can decrease the possibility of developing physical limitations by walking more,” according to physical therapist Daniel K. White, Sc.D., PT, of Boston University, and his colleagues.

Key points:

  • Increased steps (1,000 more steps per day) were associated with a lower risk for later buy avodart online uk deterioration whether assessed on an objective performance-based measure or on a self-report measure.
  • Walkers who totaled 5,000 to 7,500 steps per day cut their risk of complications from osteoarthritis in half.
  • Less than one-third of primary care physicians advise their patients with osteoarthritis to walk.
  • White and his group suggest that physicians who are recommending walking to their patients set an initial goal of 3,000 steps per day.

Even the lightest of physical activity can help reduce disability

Here’s a study that disputes the old adage, “no pain, no gain.” According to a study published in British Medical Journal, results indicated that light-intensity physical activity is beneficial. Such activity can decrease your risk for the onset of osteoarthritis disability, or, if you already have that, can decrease the progression of the disability. The study was specific to knee osteoarthritis.

Dorothy Dunlop, buy avodart professor of medicine at Northwestern University Feinberg School of Medicine, points out that these findings can encourage patients who cannot increase their level of physical activity because of health limitations. She said, “We were delighted to see that more time spent during the day, simply moving your body, even at a light intensity, may reduce disability.” Read the full article here.

More Pain as You Gain?

How does obesity affect the pain of osteoarthritis (OA)? It may sound like a simple question, but this article reports on a study that sought to determine whether patients with a higher body mass index (BMI), a measure of weight in relation to height, experienced greater pain than their less-obese friends and neighbors who also suffered with osteoarthritis.

Some key points:

  • The heavier you are, the more likely you are to develop osteoarthritis.
  • Osteoarthritis is not necessarily buy avodart online more prevalent today than it has been in the past.
  • Patients with a higher BMI reported more pain, regardless of the severity of their joint damage.
  • For each level of arthritis severity, pain scores were higher among obese patients than among non-obese patients.
  • Hormones associated with obesity may affect the severity of knee arthritis and pain.
  • A decrease in body weight could decrease arthritis pain.
