Weather doesn`t cause low back pain, say scientists
Washington: Aussie scientists have shunned the belief that low back pain are linked to weather conditions such as temperature, humidity, air pressure, wind direction and precipitation.
As per to the World Health Organization (WHO), nearly everyone experiences low back pain at some point in their life, making it the most prevalent musculoskeletal condition and affecting up to 33 percent of the world population at any given time. Those with musculoskeletal (bone, muscle, ligament, tendon, and nerve) pain report that their symptoms are influenced by the weather. Previous studies have shown that cold or humid weather, and changes in the weather increase symptoms in patients with chronic pain conditions.
Dr. Daniel Steffens form the University of Sydney said that patients believe that weather impacts their pain symptoms, but there were few robust studies investigating weather and pain, specifically research that does not rely on patient recall of the weather.
For the present case-crossover study, 993 patients seen at primary care clinics in Sydney were recruited between October 2011 and November 2012. Weather data from the Australian Bureau of Meteorology were sourced for the duration of the study period. Researchers compared the weather at the time patients first noticed back pain (case window) with weather conditions one week and one month before the onset of pain (control windows).
Results showed no association between back pain and temperature, humidity, air pressure, wind direction or precipitation. However, higher wind speed and wind gusts did slightly increase the chances of lower back pain, but the amount of increase was not clinically important.
Dr. Steffens concluded that their findings refute previously held beliefs that certain common weather conditions increase risk of lower back pain.
The study is published in the journal of the American College of Rheumatology, Arthritis Care and Research.
