Detailed Description
This supplement expands the parent research project to include three additional Aims and the recruitment of the 70 additional participants. The additional participants will undergo the same assessment and intervention procedures outlined in the parent project to permit leveraging the full cohort to evaluate the supplemental Aims.
The overall objective is to examine the impact of opioid use on patient-centered and mechanistic outcomes related to SMT and explore the impact on SMT followed by various co-interventions. The goal of this research is to better tailor SMT protocols to optimize outcomes for patients with LBP who are opioid users and facilitate efforts to reduce reliance on opioid pain management among those with LBP. Accomplishing this goal will facilitate future research evaluating the efficacy of non-pharmacologic alternative pain management strategies for individuals with LBP.
Specific Aims to be addressed through this supplement are:
- Compare baseline psychological, mechanistic and LBP-related characteristics between sub-groups of participants with LBP based on opioid use.
- Examine the association of opioid use with changes in mechanistic and patient-centered outcomes between a baseline assessment and subsequent assessment after 1-week and completion of a 2-session SMT intervention protocol.
- Explore the moderating effects of opioid use on mechanistic and patient-centered outcomes obtained 4 weeks following SMT intervention with varied co-intervention components.
Examining these aims as a supplement to the parent project will allow evaluation of whether or not opioid use impacts short-term mechanistic and patient-centered outcomes of SMT (Aim 2), and will explore if the longer-term effects of the three co-interventions differ between opioid users and non-users. (Aim 3). This research will also compare baseline characteristics between participants who are or are not opioid users (Aim 1).

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: SMT Only
All patients receive 2 SMT sessions in the first week.
|
The subject is supine.
The clinician stands opposite the side to be manipulated and side-bends the subject away from the side to manipulate.
The side to be manipulated is the more painful.
If the subject cannot identify a more painful side the clinician selects a side.
The clinician rotates the subject, and delivers a high-velocity, low-amplitude (HVLA) thrust to the pelvis in a posterior/inferior direction.
The clinician notes if a cavitation (ie, a "pop") occurred.
If it does, SMT treatment is complete.
If no cavitation occurs, the subject is repositioned and SMT is performed again.
If no cavitation occurs on the second attempt, the clinician manipulates the opposite side.
A maximum of 2 attempts per side is permitted.
If no cavitation is noted by that time, SMT treatment is complete.
Substitution with a side-posture HVLA technique is allowed if the preferred technique is not possible due to subject preference or comfort.
Other Names:
|
EXPERIMENTAL: SMT extended
All patients receive 2 SMT sessions in the first week.
This arm also involves 6 additional SMT sessions.

Patients will be instructed in mid-range exercises and will be further assessed for a directional preference.
A directional preference is present if movement in a particular direction decreases LBP intensity or causes symptoms to centralize towards the midline.
If a subject has a directional preference he or she will be prescribed exercises specifically in that direction along with mid-range exercise.
Otherwise the subject will be assigned exercises moving into either flexion or extension based on the clinician's discretion.
Subjects will perform their prescribed exercises at treatment sessions and will be instructed to perform the exercises daily on other days.

Measure Description |
Time Frame |
---|---|---|
Multifidus Activation
Time Frame: Baseline, 1-week, 4-weeks, 3 months
|
Multifidus activation wis measured with brightness-mode ultrasound images using a 60mm, 2-5 MHz curvilinear array.
The subject is prone.
The ultrasound transducer is placed just lateral to midline and angled medially until a parasagittal view of the multifidus is obtained.
Images are acquired at each level with the multifidus at rest and during submaximal contraction elicited by the subject lifting the contralateral arm about 2 inches while holding a weight proportional to body weight.
Three images in each state are acquired and averaged.
Offline multifidus thickness measures are obtained from the distance between the posterior-most aspect of the facet joint inferiorly and the plane between the multifidus and thoracolumbar fascia superior.
Muscle activation is calculated as the change in thickness at rest and submaximal contraction and expressed in mm.

Baseline, 1-week, 4-weeks, 3 months
|
Spinal Stiffness
Time Frame: Baseline, 1-week, 4-weeks, 3 months
|
Spinal stiffness is assessed with a mechanically-assisted indentation device over the spinous processes.
Indentation involves advancement of the probe from a 5 N pre-load to 60 N final load maintained for 1 second, then the probe raises automatically.
Three indentation trials are performed with mean values used for analysis.
Indentation data (force and displacement) are used to calculate stiffness variables.
Global stiffness (N) is calculated as the slope of the force displacement curve between 5 - 60 N, representing stiffness of underlying tissues during indentation.
