For people who experience back pain with sciatica, meaning their pain radiates into their leg, it may be worthwhile to start physical therapy right away, according to new research reported October 6, 2020, in . That approach is different from the initial advice doctors often give patients with back pain, which is to try to remain active and give their symptoms time to subside before considering treatment like physical therapy.
The study, a randomized clinical trial led by researchers at 麻豆学生精品版, showed that patients with sciatica who were treated with four weeks of physical therapy experienced less disability in the year following their initial doctor鈥檚 visit than patients who followed the usual wait-and-see approach.
鈥淎s is true for everything with back pain, it鈥檚 not the magic bullet for everybody,鈥 says associate dean for research in the College of Health, who led the study. 鈥淏ut it seems that physical therapy is something that can be offered to patients to help them regain their activity and recover more quickly.鈥
Most people experience back pain at some time in their lives, and about 30 percent of these episodes include sciatica. For many, the pain resolves on its own, but for others, it continues for months or years. While not everyone needs physical therapy to get better, Fritz and her colleagues wondered whether some patients鈥攑articularly those with sciatica, for whom outcomes tend to be worse than for patients with back pain alone鈥攚ere missing a critical opportunity to curb their symptoms and avoid a prolonged episode of pain.
"Physical therapy is something that can be offered to patients to help them regain their activity and recover more quickly.鈥
To find out, Fritz and collaborators at Intermountain Healthcare enrolled 220 patients with back pain and sciatica in a clinical trial. All were between 18 and 60 years old and had consulted primary care doctors at U of U Health or Intermountain Healthcare about back pain that had begun within the previous 90 days. On average, participants had been experiencing back pain for 35 days.
The study participants were randomly assigned to two treatment groups. Those in the physical therapy group received an active form of physical therapy for four weeks. Physical therapists primarily used exercises and manual techniques such as hands-on spinal mobilization, tailoring the specifics of the treatment to individual patients. Those in the other group received no therapy but were advised to remain active.
Patients reported on their level of pain and its impact on their lives鈥攕uch as their ability to care for themselves and participate in social activities鈥攁fter four weeks, then again at six months and one year. At each point, patients who had completed physical therapy immediately after their primary care visit reported less disability than patients who took the wait-and-see approach.
Importantly, those differences were large enough to be considered clinically meaningful at the early-outcome time point, suggesting real benefits for patients, says study author Gerard Brennan, P.T., Ph.D., a senior research scientist at Intermountain Healthcare. 鈥淭his clearly says if you intervene early, these patients can do well,鈥 he says.
During the one-year study, a small percentage of participants chose to receive steroid injections or undergo surgery to treat their pain. These interventions were equally common whether or not patients received early physical therapy.
It is not known which components of the physical therapy program contributed most to patients鈥 response to the treatments. The study organizers also note that outcomes may have been influenced by the different levels of provider contact experienced by the two treatment groups.
Fritz says she and her colleagues undertook this study because it鈥檚 important for patients who seek care for their back pain to have evidence-based treatment options. The next critical step, she notes, will be integrating the findings into clinical practice.
