Rest and exercise `equally effective on lower back pain`
Lower back pain caused by pathological changes in the bones of spine can be hard to treat and the presently recommended therapy of exercise and staying active usually does not help alleviate the pain.
Results of a trial, comparing exercise therapy, and staying active, to daily rest and lumbar support, showed that both treatments resulted in the same small level of improvement in pain, disability, and general health.
Modic changes (MC) in the spine, where the bone marrow is infiltrated by serum (fluid), fatty deposits, or by sclerosis, can only be seen using Magnetic Resonance Imaging (MRI).
It has been suggested that these MC, associated with non-muscular lower back pain, are caused by mechanical stress and therefore might be more responsive to rest than to exercise.
This study, based at the Spine Centre of Southern Denmark, was designed to treat patients for a 10 week trial (with follow up after one year).
It consisted of either two hours rest a day, and wearing a lumbar support to help reduce load on the spine, or exercise therapy, once a week, supplemented by active living.
The study measured levels of pain, disability, general health, depression and the number of patients achieving a minimum clinically important improvement in their condition.
Patients also reported any back problems or sick leave in weekly text messages (SMS).
The team led by Rikke K Jensen found no differences for any of the makers between the two groups at either the 10 week or the year catch up. Similarly there was no difference in the course of the disease between the two groups.
