Study summary

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.

Study arms

  • Active comparator
    augmented spinal manipulative therapy

    Participants in this group will receive spinal manipulative therapy provided by a practitioner interacting in a warm and friendly way who is free to respond to participant conversation. Participants in this group will receive information about the effectiveness of spinal manipulative therapy for some individuals experiencing low back pain.

    Procedure: spinal manipulative therapy

  • Active comparator
    neutral spinal manipulative therapy

    Participants in this group will receive spinal manipulative therapy provided by a practitioner engaging in minimal interaction. Participants in this group will not receive information about the effectiveness of spinal manipulative therapy for some individuals experiencing low back pain.

    Procedure: spinal manipulative therapy

What researchers measure

Primary outcomes

  1. numeric pain rating scale

    0 to 100 with 0= no pain at all to 100= worst pain imaginable

    Time frame: Change in baseline at 2 weeks

Secondary outcomes

  1. Oswestry Disability Index

    0 to 100 with 0= no perceived disability to 100= greatest perceived disability

    Time frame: Change in baseline at 2 weeks

  2. Back Performance Scale

    0 to 15 with lower scores indicating better performance

    Time frame: Change in baseline immediately following spinal manipulative therapy during day 1 and at 2 weeks

  3. Quantitative Sensory Testing

    standardized thermal and pressure stimuli will be applied and participant will rate the pain associated with each using a 0= no pain to 100= worst pain imaginable numeric pain rating scale or a mechanical visual analog scale anchored with no pain and worst pain imaginable

    Time frame: change in baseline immediately following spinal manipulative therapy during day 1

  4. Patient Centered Outcome Questionnaire

    Participants indicate their usual level, desired level, successful level, and expected level of pain, fatigue, emotional distress, and interference using a 0= none at all to 100= worst imaginable numeric rating scale

    Time frame: change in baseline immediately following spinal manipulative therapy during day 1

  5. Working alliance subscale of the Pain Rehabilitation Expectation Scale

    Scored from 16= lesser therapeutic alliance to 64= greater therapeutic alliance

    Time frame: change in baseline immediately following spinal manipulative therapy during day 1

  6. North American Spine Society Lumbar Spine Outcome Assessment

    Participants will answer 3 questions: 1) If you had to spend the rest of your life with the low back pain you have right now, how would you feel about it? Scored from 1= very dissatisfied to 5= very satisfied; 2) Would you have the same intervention you received in this study again for low back pain? Scored from 1=Definitely not to 5= definitely yes; 3) . How would you rate the overall results of the intervention you received in this study for low back pain? Scored from 1= Terrible to 6= Excellent

    Time frame: 2 weeks

  7. Semi- structured qualitative interview seeking insight into answers on the working alliance subscale of the pain rehabilitation expectation scale

    a brief semi- structured interview

    Time frame: 2 weeks
