Affecting one in five adults, arthritis mainly hurts — it causes tenderness, stiffness, and pain. A new Johns Hopkins study finds people with arthritis who practiced yoga for just eight weeks had a 20 percent improvement in health, pain, energy, and mood. 
  
 “The big message is that all people with arthritis need to be physically active, yet individuals with arthritis are less active than their peers,” Dr. Susan J. Bartlett, Ph.D., an adjunct associate professor of medicine at Johns Hopkins and associate professor at McGill University, told Medical Daily. As lead investigator of the study, Bartlett added the results suggest that “yoga is a safe and feasible option for people with arthritis,” an option offering “both mental and physical benefits.” 
  
 Rheumatoid Arthritis and Osteoarthritis 
  
 Participants in the study suffered from knee osteoarthritis and rheumatoid arthritis, two of the most common forms of arthritis. Rheumatoid arthritis is a form of inflammatory arthritis, a key symptom of which is swelling of the lining of the joints, as described in the clinical trial. A chronic disease, inflammatory arthritis can cause long-term joint damage, resulting in loss of function and chronic pain, both resulting in potential disability. Osteoarthritis, according to Bartlett, is the most common form of arthritis by far, affecting both men and women equally. Knee osteoarthritis, where the cartilage in this joint gradually wears away causing bone to scrape against bone, is degenerative. 
  
 The objective of the study, conceived by Bartlett, was to learn how people with rheumatoid arthritis and knee osteoarthritis responded to a program of yoga, a set of ancient Indian theories and practices, which includes poses, breathing techniques, and relaxation exercises. The study included 75 sedentary adults who suffered from either rheumatoid arthritis or knee osteoarthritis. All the study participants were over the age of 18 and most, 95 percent, were women. Why the male-female imbalance? 
  
 “Rheumatoid arthritis disproportionately affects women,” said Bartlett, noting 70 percent of people with this condition are women. Additionally, “women are much more likely to express interest and participate in all clinical trials that involve lifestyle changes (e.g., physical activity),” she said. 
  
 After Bartlett and her co-researchers randomly separated participants into two groups, they assigned one group to eight weeks of yoga (two 60-minute classes and one home practice/week) while offering the other group academic classes about arthritis. 
  
 At the eight week mark, the researchers compared the two groups. Those doing yoga reported a 20 percent improvement in pain, energy level, mood, and physical function, including the ability to complete physical tasks. Little difference between the groups existed when partipants were tested for balance and upper body strength, but walking speed improved slightly for the yoga group. Most important, the yoga participants continued to exercise for a longer period than occurs following many clinical trials, where commonly half of the participants stop exercising within just three months, Bartlett explained. 
  
 “Anecdotally, several people told us years later this was life changing for them — it gave them a much more positive view of their bodies (and what they were able to accomplish physically), their illness, and their ability to impact their overall health,” said Bartlett, who added, “One person went on to become a marathon runner!"

 Exercise works all kinds of wonders on the human body, from stabilizing joints to improving muscle mass to reducing inflammation. That’s pretty motivating when your body feels good—but less so when it aches. 44% of people with arthritis say they don’t exercise, and close to 80% aren’t active enough. 
  
 But a recent randomized controlled trial published in the Journal of Rheumatology finds that people with arthritis who practice yoga can reap impressive physical and mental benefits. Those who practiced yoga three times a week had an improvement in pain levels, energy, mood and physical health compared to the group that didn’t do yoga—and the effects lasted even nine months later. 
  
 “There’s kind of a myth that says if you have arthritis, the good thing to do is to rest your joints,” says one of the study’s authors Dr. Clifton O. Bingham III, associate professor of medicine at Johns Hopkins University School of Medicine and director of the Johns Hopkins Arthritis Center. “I think the study is more evidence that, in fact, that’s not true.” 
  
 In the trial, the researchers recruited 75 adults who didn’t exercise and had rheumatoid arthritis, a condition that affects the body’s smaller joints like the wrists, feet and ankles, or knee osteoarthritis, which is localized to the knee. One group practiced a specialized kind of yoga for eight weeks: group classes modified by arthritis experts to take the stress off of joints. Each hour-long class took place twice a week, and the people in the group were told to do a weekly class at home. The other group exercised as usual.

 After eight weeks, the people in the yoga group saw improvement across all measures compared to the control group. Their physical health, flexibility, pain levels, walking capacity and depression scores were better. The benefits lasted nine months later, when researchers checked up on them again. 
  
 Some of the people in the yoga group are Bingham’s patients and still doing yoga five-plus years later, he says. “It really has been transformative for a lot of my patients,” he says. “What [one patient] learned from the yoga experience was the philosophy of non-harming and the idea that where she is today is good enough,” Bingham says. “Those types of things are very difficult to measure in terms of an outcome from a study, but we certainly saw them on a real one-on-one patient level.” 
  
 Not every yoga class is safe for people with arthritis, Bingham says, and he advises people to consult with their arthritis specialist before starting. It’s important to also ask the yoga teacher if they have experience dealing with the disability, he says. Gentle yoga, prenatal yoga or classes designed for an older or disabled population are good places to start. 
  
 The results of the study suggest that gentle yoga can be a safe practice for people with arthritis, and that it doesn’t make symptoms worse—in fact, quite the opposite. “You can carefully and cautiously exercise and do activities,” Bingham says. “Yoga, in the way that we’ve done it, can be one of those.” ||||| The seed for this crawl was a list of every host in the Wayback Machine

"There's kind of a myth that says if you have arthritis, the good thing to do is to rest your joints," says a John Hopkins professor who co-authored a study that might bust the myth wide open. In the study of 75 sedentary adults with rheumatoid arthritis or knee osteoarthritis published in the Journal of Rheumatology, researchers found that subjects who practiced an hour of yoga three times a week for eight weeks enjoyed higher energy, less depression, reduced pain, and improved flexibility and walking ability, reports Time. Researchers pegged the improvement at 20% over those in the non-yoga control group and say the benefits were still evident nine months later. Lead author Susan Bartlett tells Medical Daily that one subject even went on to become a marathon runner. More than 95% of the study's subjects were female, but Bartlett tells the website that for the purposes of this study, it made sense: 70% of rheumatoid arthritis sufferers are women. One caveat, one of the researchers tells Time: Not all yoga classes are equal and could even harm arthritis patients, so he advises checking with one's doctor and seeking out the gentler regimens found in classes for older, disabled, or pregnant students before heading straight into Downward-Facing Dog.
