Physical Therapy Referral From Primary Care for Acute Back Pain With Sciatica : A Randomized Controlled Trial.

Sciatica, the leg pain that comes from an irritated nerve root in the back, is common enough that primary care doctors have to decide fairly quickly how to manage it. This trial asked whether sending people to physical therapy soon after diagnosis helps more than the usual approach of a single education session, in patients whose sciatica had started within the past three months. Everyone received imaging and medication as their doctor saw fit, and then was randomly assigned to either usual care alone or usual care plus four weeks of physical therapy involving exercise and manual therapy.

People referred early to physical therapy reported less disability at six months and at one year, and were more likely to say their treatment had succeeded a year later than those who only got usual care. Health care use and missed workdays did not differ between groups. The trial could not blind patients or providers to which treatment they got, and it can't tell us which specific physical therapy techniques mattered, so the finding shows a benefit from the overall referral pathway rather than any single treatment ingredient.

If you've ever had sciatica, the shooting or burning leg pain that can come with back trouble, you know how disruptive it is and how uncertain the path to feeling better can seem. This study looked at whether people newly diagnosed with sciatica by their primary care doctor did better if they were also sent to physical therapy for four weeks, compared with just getting standard advice and education.

Everyone in the study still got the usual imaging and medications their doctor decided on. The people who went to physical therapy early reported less disability and somewhat less pain, both after a month and still a year later, compared with those who only received the standard education visit. They were also more likely to say their treatment worked well after a year.

However, the two groups didn't end up using different amounts of other health care or missing different amounts of work. Because patients and doctors both knew who was getting physical therapy, and because the mix of specific therapy techniques used couldn't be teased apart, this doesn't tell us exactly which part of the therapy made the difference. It does suggest that referring people to therapy early may be more helpful than education alone.

This is a summary of research, not medical advice. Talk to your own healthcare provider about anything affecting your care.

This was a randomized controlled trial of 220 adults aged 18 to 60 with sciatica of less than 90 days' duration, recruited from primary care within two Salt Lake City health systems. Participants were randomized to usual care, one education session, or early physical therapy referral consisting of one education session plus four weeks of exercise and manual therapy, with imaging and medication use left to primary care provider discretion beforehand.

The primary outcome, Oswestry Disability Index at six months, favored the early physical therapy group by a relative difference of -5.4 points (95% CI, -9.4 to -1.3; P = 0.009), and this advantage persisted at one year (-4.8 points, CI, -8.9 to -0.7), along with lower back pain intensity (-1.0 points, CI, -1.6 to -0.4). Self-reported treatment success at one year was higher with early physical therapy (45.2% versus 27.6%; relative risk, 1.6, CI, 1.1 to 2.4). No significant between-group differences emerged in health care utilization or missed workdays.

Key limitations include lack of blinding for patients and providers, which could inflate perceived benefit, and inability to isolate which physical therapy components drove the effect. The sample size, while adequate for the primary comparison, remains modest for secondary and subgroup interpretations.
