About this study

The goal of this clinical trial is to learn if an erector spinae plane block (ESPB; a type of nerve block) works to reduce pain in adults presenting to the emergency department with low back pain. It will also learn if the ESPB reduces pain, disability, and return to work at 7 days. The main questions it aims to answer are:

  1. Does the ESPB reduce short-term pain in participants with low back pain?
  2. Does the ESPB reduce longer-term pain, reduce disability, and improve return to work and activities in participants with low back pain?

Researchers will compare ESPB to a placebo (an injection that does not involve a nerve block) to see if ESPB works to treat low back pain.

Participants will:

Receive either the ESPB or a placebo injection in the emergency department Report their pain scores for up to 120 minutes Report their pain, disability, and return to work at 7 days

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pain score at 120 minutes post-intervention as assessed using a 10-point numeric rating scale

    Zero is equivalent to no pain and 10 indicates worst pain imaginable

    Measured: Change from baseline to 120 minutes post-intervention

Secondary outcomes (7)
  1. Pain score at 30 minutes post-intervention as assessed using a 10-point numeric rating scale

    Zero is equivalent to no pain and 10 indicates worst pain imaginable

    Measured: Change from baseline to 30 minutes post-intervention

  2. Pain score at 60 minutes post-intervention as assessed using a 10-point numeric rating scale

    Zero is equivalent to no pain and 10 indicates worst pain imaginable

    Measured: Change from baseline to 60 minutes post-intervention

  3. Degree of disability assessed via the Roland-Morris disability questionnaire at 7 days

    Participants will be scored using the validated Roland-Morris disability questionnaire.

    Measured: Assessed as the change in Roland-Morris disability questionnaire scores between baseline and 7 day follow up

  4. Pain score at 7 days post-intervention as assessed using a 10-point numeric rating scale

    Zero is equivalent to no pain and 10 indicates worst pain imaginable

    Measured: Pain score assessed at 7 days post-intervention

  5. Opioid medications taken in the 7 days following the intervention

    Calculated in morphine milligram equivalents

    Measured: Measured at 7 days post-intervention

  6. Follow up visits related to low back pain in the 7 days following the intervention

    Based upon patient self-report

    Measured: Assessed at 7 days

  7. Return to work and activities assessed via the Work Productivity and Activity Impairment Questionnaire: General Health version 2.0

    Assessed using the validated Work Productivity and Activity Impairment Questionnaire: General Health version 2.0 questionnaire

    Measured: Assessed at 7 days
