This study considers whether treatment effects in response to spinal manipulative therapy for individuals experiencing low back pain are dependent upon the context in which the intervention is provided. Half of the participants will receive spinal manipulative therapy with encouragement to interact with the provider and information to enhance expectations for the effectiveness of the intervention. The other half will receive spinal manipulative therapy with minimal interaction with the provider.
