Manual Therapy by General Medical Practitioners for Nonspecific Low Back Pain in Primary Care: The ManRück Study Protocol of a Clinical Trial

Background: Nonspecific low back pain (LBP) is a common reason for accessing primary care. Manual therapy (MT) may be an effective treatment, but data from clinical studies including relevant subgroups and clinical settings are sparse. The objective of this article is to describe the protocol of a study that will measure whether an MT protocol provided by general medical practitioners will lead to a faster pain reduction in patients with nonspecific LBP than does standard medical care.
