A Randomized, Double-Blind, Placebo-Controlled Trial of Naproxen With or Without Orphenadrine or Methocarbamol for Acute Low Back Pain.
Summary
Low back pain is a common cause of visit to emergency department. It is not clear if skeletal muscle relaxants are of benefit for patients with acute low back pain. This is a randomized study to determine if skeletal muscle relaxants, when combined with naproxen, improve outcomes more than naproxen alone
