Trial Outcomes & Findings for Diazepam Use With Standard Management for Acute Low Back Pain (NCT NCT02646124)

NCT ID: NCT02646124

Last Updated: 2018-08-01

Results Overview

The Roland Morris Disability Questionnaire (RMDQ) is a 24 item instrument that evaluates the impact of low back pain on one's daily life. It is most sensitive for patients with mild to moderate disability due to acute, sub-acute or chronic low back pain. Each question can be answered as either a "yes" or "no". The score ranges from 0 to 24 where a higher score reflects greater impairment and, therefore, worsening in the quality of life. The change in RMDQ is obtained by subtracting the RMDQ score at one week after discharge from the baseline score.
