Orphenadrine and Methocarbamol for LBP

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

Primary outcomes

  1. Functional Impairment as Measured on the Roland Morris Disability Questionnaire

    Time frame: 1 week

    Change in Roland Morris Disability Questionnaire between baseline and 1 week.

    The low back pain functional disability scale is the RMDQ. The RMDQ is a 24-item low back pain functional scale recommended for use in low back pain research.Higher scores signify greater low back-related functional impairment.0= no functional impairment, 24= severe functional impairment.

Secondary outcomes

  1. Cases of Moderate or Severe LBP

    Time frame: 1 week

    Participants with moderate to severe low back pain after treatment as report on the following ordinal scale: severe, moderate, mild, or none

  2. Medications--Patient Self Report of Medication Use

    Time frame: 1 week

    Participants still using medication such as analgesics for LBP after treatment

  3. Patient Satisfaction With Treatment

    Time frame: 1 week

    The number of participants with affirmative response to the following question: Do you want the same medication combination during a subsequent episode of LBP. This is a patient-centered outcome that allows each individual to determine the desirability of the intervention.
