LOW BACK PAIN RECURRENCE REDUCED WITH WALKING

.

    


A world-first study has found that adults with a history of low back pain went nearly twice as long without a recurrence of their back pain if they walked regularly.

About 800 million people worldwide have low back pain, and it is a leading cause of disability and reduced quality of life.

Repeated episodes of low back pain are also prevalent, with seven in 10 people who recover from an episode going on to have a recurrence within a year.

Current best practices for back pain management and prevention suggest combining exercise and education. However, some forms of exercise are not accessible or affordable to many due to their high cost, complexity, and need for supervision.

A clinical trial by Macquarie University's Spinal Pain Research Group examined whether walking could be a practical, cost-effective, and accessible intervention.

The trial followed 701 adults who had recently recovered from an episode of lower back pain. Participants were randomly allocated to an individualized walking program and six physiotherapist-guided education sessions over six months or to a control group.

Researchers followed the participants for between one and three years, depending on when they joined, and the results have now been published in the latest edition of The Lancet.

The paper's senior author, Macquarie University Professor of Physiotherapy Mark Hancock, says the findings could profoundly impact managing low back pain.

"The intervention group had fewer occurrences of activity limiting pain compared to the control group and a longer average period before they had a recurrence, with a median of 208 days compared to 112 days," Professor Hancock says.

"Walking is a low-cost, widely accessible, and simple exercise that almost anyone can engage in, regardless of geographic location, age, or socio-economic status.

"We don't know exactly why walking is so good for preventing back pain, but it is likely to include the combination of the gentle oscillatory movements, loading and strengthening the spinal structures and muscles, relaxation and stress relief, and release of 'feel-good' endorphins.

"And of course, we also know that walking comes with many other health benefits, including cardiovascular health, bone density, healthy weight, and improved mental health."

Lead author Dr Natasha Pocovi says in addition to providing participants with longer pain-free periods, the program was very cost-effective.

"It not only improved people's quality of life, but it reduced their need to seek healthcare support and the amount of time taken off work by approximately half," she says.

"The exercise-based interventions to prevent back pain that have been explored previously are typically group-based and need close clinical supervision and expensive equipment, so they are much less accessible to most patients.

"Our study has shown that this effective and accessible means of exercise has the potential to be successfully implemented at a much larger scale than other forms of exercise."

To build on these findings, the team hopes to explore how they can integrate the preventive approach into the routine care of patients who experience recurrent low back pain.

PEOPLE WITH OBESITY BURN LESS CALORIES DURING THE DAY

  PEOPLE WITH OBESITY BURN LESS CALORIES DURING THE DAY Building on prior studies with healthy-weight participants, the new research includes different body sizes.         New research indicates that weight influences how and when bodies burn energy. An Oregon Health & Science University study published in the journal  Obesity  found people who have a healthy weight use more energy during the day, when most people are active and eat, while those who are obese spend more energy during the night when most people sleep. The study also found that during the day, those with obesity have higher levels of the hormone insulin -- a sign that the body is working harder to use glucose, an energy-packed sugar. "It was surprising to learn how dramatically the timing of when our bodies burn energy differed in those with obesity," said the study's first author, Andrew McHill, Ph.D., an assistant professor at the OHSU School of Nursing and the Oregon Institute of ...

WHAT CAUSES ITCHING, AND WHAT STOPS IT?

  WHAT CAUSES ITCHING, AND WHAT STOPS IT?         It can be a relief to scratch the occasional itch, but when itch gets out of control, it can become a severe health problem. How does the body know when to stop? Scientists at UC San Francisco are getting close to an answer. In a breakthrough that could transform how doctors treat conditions from eczema to allergies, they have discovered a feedback loop centered on a single immune protein called IL-31 that causes the urge to itch and dials back nearby inflammation. The findings, published on October 13th in  Science Immunology , lay the groundwork for a new generation of drugs that interact more intelligently with the body's innate self-regulating ability. Previous approaches suggested that IL-31 signals itch and promotes skin inflammation. However, the UCSF team discovered that nerve cells, or neurons, that respond to IL-31, triggering a scratch, also prevent immune cells from overreacting and causing more ...

A VEGAN DIET IMPROVES CARDIOVASCULAR HEALTH, ACCORDING TO A NEW STUDY

  A VEGAN DIET IMPROVES CARDIOVASCULAR HEALTH, ACCORDING TO A NEW STUDY         In a study with 22 pairs of identical twins, Stanford Medicine researchers and their colleagues have found that a vegan diet improves cardiovascular health in as little as eight weeks. Although it's well-known that eating less meat improves cardiovascular health, diet studies often need to be enhanced by genetic differences, upbringing, and lifestyle choices. By studying identical twins, however, the researchers were able to control for genetics and limit the other factors, as the twins grew up in the same households and reported similar lifestyles. "Not only did this study provide a groundbreaking way to assert that a vegan diet is healthier than the conventional omnivore diet, but the twins were also a riot to work with," said Christopher Gardner, Ph.D., the Rehnborg Farquhar Professor and a professor of medicine. "They dressed the same, they talked the same, and they had a banter ...
