The purpose of this study is to determine the short-term effects of thoracic spine thrust manipulation on participants with low back pain. Participants in this study will be randomized to receive either the lower thoracic spinal manipulation and a standard set of exercises, or a sham manipulation and the same standard set of exercises. It is hypothesized that thoracic manipulation when combined with core strengthening exercises will have positive short term improvements in pain and function for patients with LBP as compared to a sham manipulation combined with core strengthening exercises.
This study aims to use a randomized controlled trial design to investigate the effects of thoracic spinal manipulation in conjunction with core strengthening exercises when compared to a sham manipulation and core strengthening exercises on patients with low back pain. Core strengthening exercises have been shown to improve pain and functional status in patients with non-specific low back pain when compared to conventional exercise. However, there is strong evidence to suggest that exercise alone is not adequate for the management of low back pain. Spinal manipulation has demonstrated promising results for the management of low back pain, but it is unclear whether the targeted location of manipulation is important. It is hypothesized that thoracic manipulation when combined with core strengthening exercises will have positive short term improvements in pain and function for patients with LBP as compared to a sham manipulation combined with core strengthening exercises based on the theory of regional interdependence. The specific aims of the study are as follows:
The ability to demonstrate the effectiveness of a manipulation targeted at the thoracic spine in conjunction with core exercises could provide clinicians a simple, effective treatment strategy for low back pain that not only has minimal injury risk, but has the potential to improve pain and function, ultimately decreasing the healthcare costs associated with low back pain.
The effects of treatment on disability, fear-avoidance, and pain will be analyzed using a 2x2 repeated measures multivariate analysis of variance (MANCOVA), with pre/post-test measures and time as the two factors and duration of symptoms serving as a covariate. An independent t test will be used to determine differences for the Global Rating of Change between groups at follow up, and the number needed to treat (NNT) will be calculated. Spinal manipulation has some potentially serious risks including, fracture, numbness, tingling, or injury to the spinal cord. However, these risks are very low in the thoracic spine where manipulation is targeted during this study. In a recent systematic review which evaluated the safety of thoracic spine manipulation, the authors found only seven cases of serious trauma which have resulted from thoracic spine manipulation. The majority of these cases were performed by a chiropractor and it is unsure whether participants had contraindications to manipulation. In order to mitigate these risks, participants will be thoroughly screened for contraindications to spinal manipulation. If an adverse event does occur, the participant will be referred to the appropriate provider and their participation in the study will be discontinued.

| Manipulation | Other | Middle Thoracic: Participants are placed in the supine position with their arms over their chest. The clinician rolls the participant to their side and places the fulcrum at the desired thoracic segment and the participant is rolled back onto the clinician's hand. The participant is instructed to take a deep breath. As the participant is exhaling, the clinician uses his body to push through the participant's arms to perform a high velocity thrust in an anterior to posterior directed force. Lower Thoracic: With the patient in a prone position, the clinician achieves a "skin lock" with both pisiforms over the transverse processes of the target vertebra. The clinician then uses his body to push down through his arms to perform a high-velocity, low-amplitude posterior to anterior thrust. |

| Change from Baseline on Modified Oswestry Disability Questionnaire (MODQ) | The MODQ is a functional scale assessing the impact of low back pain on daily activities by assigning a disability score according to the answered questions. The scale includes 10 questions regard the level of pain and interference with several physical activities including: sleeping, lifting, travelling, self-care, and social life. Each question has six possible responses (scored from 0 to 5), and patients are asked to pick the one that most accurately responds to their condition. The sum of the response is divided by the total possible score and multiplied by 100 to receive a percentage of disability with 0% corresponding to no disability and 100% corresponding to a great deal of disability. | Administered at the initial and final sessions (no more than 2 weeks apart) |

| Change from Baseline on Numeric Pain Rating Scale (NPRS) | An 11-point numeric pain rating scale will be used to assess pain before and after treatment. The scale ranges from 0 "no pain" to 10 "worst possible pain." | Administered at the initial and final sessions (no more than 2 weeks apart) |

| Sham Manipulation | Other | The participants are positioned in prone and the clinician's hands are placed with the pisiforms of each hand over the transverse processes of the target vertebra. The clinician will only apply minimal pressure and slide the hands across the skin to mimic the manipulative thrust. This sham procedure has been shown to be an adequate sham comparator for spinal manipulative therapy (SMT) with similar expectations and believability as SMT active treatment |
|
|
| Core Strengthening Exercises | Other | Both groups will receive the following exercises at each visit. The core strengthening (core strengthening) exercises are a standard protocol used by Richardson et al and Franca et al which are proposed to target muscles responsible for segmental stabilization, specifically the transverse abdominis (TrA) and the lumbar multifidi (LM). Exercises will include: TrA exercises in 4 point kneeling and in supine with flexed knee, LM exercises in prone, and co-contraction of TrA and LM in upright position. Three sets of 15 repetitions will be done for each exercise. |
