Early physical therapy can reduce opioid use: Study

The study screened outpatients who had recently taken opioids by including only those who hadn’t filled an opioid prescription within the prior year. The study also screened outpatients with less serious pain by including only those who had visited a doctor for their condition within 30 days of their initial diagnosis and were given at least one opioid prescription within 90 days. The final sample consisted of 88,985 patients.

After adjusting for co-morbidities, such as diabetes and hypertension, the researchers found that the odds of patients filling an opioid prescription three months to a year after their initial pain diagnosis were lower if they had participated in at least one physical therapy session within 90 days of their diagnosis. The odds were reduced by 16 percent for patients with knee pain, 15 percent for shoulder pain, 8 percent for neck pain and 7 percent for lower back pain.

The findings could be helpful to clinicians in search of pain-management options that carry fewer health risks than opioids. Studies have shown exercise therapy, a component of physical therapy reduces pain and improves function for some musculoskeletal conditions. Other studies have shown that patients with past prescriptions for opioid pain medication are at increased risk for overdose and misuse.

The study also measured whether early physical therapy was associated with a decreased need for opioids in the long-term among patient who filled prescriptions. The researchers measured the number of opioids by converting prescribed amounts to oral morphine milligram equivalents.

They found that patients who had undergone early physical therapy used 10.3 percent less opioid medication for knee pain, 9.7 percent less for shoulder pain, and 5.1 percent less for back pain in the period three months to a year after their diagnosis. There was no significant reduction in neck pain.

After early physical therapy, patients with knee pain were 66 percent less likely in the period three months to a year after their diagnosis to either fill 10 or more prescriptions or acquire a supply of opioid medication for 120 days or more. Patients with low back pain were 34 percent less likely to be chronic users if they had early physical therapy.
