Almost everyone suffers from low back pain at some point in their lives. Most recover in a few days, but for some the pain lingers and become chronic, making low back pain the world’s leading cause of disability.  

Why are some people able to recover quickly from low back pain?

For many, the answer may be early treatment with physical therapy (PT), according to a new study by researchers at Johns Hopkins Medicine.   

“Our goal was to determine if early PT for patients with lower back pain had an impact on their overall health care resource utilization,” says senior author Richard Skolasky Jr., ScD, director of the Johns Hopkins Spine Outcomes Research Center. “We were especially curious about the 30 days after initial symptom onset, as this is when patients are most likely to seek care.” 

Skolasky and his colleagues analyzed healthcare data from 2010 to 2014 for nearly a million U.S. adults with acute low back pain, excluding those suffering from serious disorders such as arthritis or spinal cord injuries. About 10% of the patients received early treatment with physical therapy.

The study findings, recently published by BMC Health Services Research, showed that patients getting early PT were significantly less likely to see a chiropractor, orthopedic surgeon or pain specialist after 30 days than those who did not get physical therapy. They were also less likely to get advanced imaging, epidural steroid injections or to visit an emergency room.

Researchers estimate that healthcare costs for a typical patient getting early PT was about $500 less over 30 days than those not receiving physical therapy.

Another key finding from the study was significant geographical differences in the use of physical therapy. Patients in the West (16%) and Northeast (15%) were nearly twice as likely to get early PT than those in the Midwest (9.4%) and South (8.6%). The authors offered no explanation for why treatment patterns varied so much by region.

The study did not specifically examine whether physical therapy benefits patients with low back pain more than other forms of treatment, but the findings suggest that they did. Researchers say health outcomes should be examined more closely in future studies.

“As the U.S. population ages, the prevalence of lower back pain is expected to increase, along with the associated costs of treating it,” says Skolasky. “Furthermore, with advances in imaging and treatments, the cost of managing lower back pain has increased substantially. Our findings have important implications that may guide health care policy when examining downstream health care costs and resource utilization.” 

Previous studies have found that physical therapy and regular exercise significantly reduces low back pain. Other studies also found little evidence to support the use of opioids, spinal injections and acetaminophen for low back pain.
