About this study

The research objective is to determine which physical therapy (PT) treatment is the most efficacious for patients with lower back pain (LBP), who have been subgrouped based on certain clinical features. There is only limited evidence that supports any one PT treatment for patients with LBP since PT treatment outcomes for exercise protocols are equivocal, given the heterogeneous clinical features of patients with LBP. Thus, classification of patients with LBP into subgroups with shared clinical features has been identified as a research priority by several groups in order to prescribe the most efficacious PT treatment for each homogeneous subgroup. The investigators hypothesize that particular PT treatments are most efficacious when applied to patients with LBP, who present with particular clinical and neuromuscular features.

Read the detailed description

The proposed studies focus on 2 schemas to classify LBP: 1) the Treatment-Based Classification (TBC) system, from which clinical prediction rules about who is most likely to benefit from spinal stabilization exercises (among others) have been developed, and 2) the Movement System Impairment-Based Classification (MSI) system, which includes 5 classifications of LBP named for the specific direction(s) of movements and alignments associated with the person's LBP.

The primary purpose of this proposal is to conduct a prospective, randomized, controlled Phase II clinical trial in order to examine whether or not treatment matched to a patient's specific signs and symptoms (patient-matched) per the TBC is more effective than the MSI system for improving short- (6 weeks) and long-term (12 and 24 months) outcomes in people with chronic LBP. A secondary purpose is to identify prognostic factors that predict clinical outcomes in the 2 treatment groups being compared.

Subjects will be assigned to one of two study arms:

  1. eligible for Treatment-Based Classification (TBC) stabilization exercises based on current criteria ('Eligible' Subject Group); and
  2. subjects who are not eligible for the TBC-based stabilization exercises ('Ineligible' Subject Group).

Within in each study arm, subjects will be randomly assigned to 1 of 2 exercise protocols for a 6-week period:

  1. stabilization - a protocol focused on improving the motor control of trunk muscles to stabilize the spine; or
  2. MSI-based - a classification-specific treatment focused on education and instruction for modifying movement strategies during functional activities, and on exercises specific to the classification category.

Laboratory measures (muscle activation, kinematics, forces) during standardized tasks will quantify neuromuscular impairments associated with LBP and clinical questionnaires will quantify changes in pain, function, and health status pre- and post-treatment. The addition of neuromuscular measures to these classification schemas could improve the sensitivity and specificity of each.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Physical Therapy rehabilitation: Stabilization exercises.Other

    Also called Trunk stabilization exercises, Segmental stabilization exercises

    The stabilization exercise protocol consists of exercises focused on improving the ability of trunk muscles to stabilize the spine, beginning with training to isolate the deeper abdominal muscles and then incorporation of these isolated contractions into other exercises. The exercise protocol progresses to include trunk flexion and extension strengthening exercises as well as abdominal bracing exercises in supine and quadruped positions, and finally to exercises in more functional positions.

  • Physical Therapy rehabilitation. Movement System Impairment (MSI) classification based exerciseOther

    Also called Specific exercise, Sarhmann exercise approach, MSI exercises

    The MSI-classification based approach focuses on education and instruction for modifying movement strategies during functional activities, and on exercises that are specific to the classification category. First there is an analysis of and instruction in modifying a subject's direction-specific alignment and movement strategies during symptomatic functional activities. Second, there is education about the principles of tissue injury and healing, and how cumulative tissue stress contributes to microtrauma and LBP. Unique to the education process is the emphasis on how using one's particular movement strategies during functional activities may accelerate tissue stress accumulation because the strategies are used repetitively. Thirdly, there is exercise prescription that includes practice in performing modified versions of the direction-specific impairment tests from the physical exam, with an emphasis on impairments that can be modified to eliminate LBP symptoms.

What does the primary outcome measure?

Change From Baseline in Oswestry Disability Scale (0-100%) (time frame: Baseline and 7 weeks). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01362049, which also lists 12 linked publications.

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Jun 2017.
