Brief Summary:
The objective of this study is to investigate the efficacy of a treatment based on Movement System Impairment based classification (MSI) model in patients with chronic non-specific low back pain.

Condition or disease Intervention/treatment Phase
Low Back Pain Other: Treatment based on Movement System Impairment model Other: General exercise Not Applicable

Detailed Description:

The subjects will be recruited from orthopedic outpatient clinics as well from the community. The examiner will screen the eligibility of each subject based on the eligibility criteria. All eligible subjects will receive information about the study and will sign an informed consent form before participating in the study.

The examiner will collect the baseline data prior to randomisation. This examiner will be blinded to patients' allocation to treatment groups. The subjects will be randomly allocated to one of two groups (treatment based on MSI model or general exercise) using a computer-generated randomisation schedule conducted by a study researcher who will not be involved with the patients and assessment of outcomes. Participant allocation will be kept in a sealed opaque envelopes using a random numerical sequence. The examiner, responsible for the treatment will open the envelope in front of the patient and will communicate him about which treatment group he will be part of. The clinical outcomes of this study will be assessed before, after the treatment (2 months) and at 4 and 6 months after randomisation.

Descriptive analyses will be done to check for data normality. The between-group comparisons to obtain the mean effects of the treatments will be conducted by means of interaction terms (group versus time interactions) using Linear Mixed Models. All data will be given to a statistician who will perform the statistical analysis in coded form. The statistical analysis will be done according to the principles of intention to treat. The SPSS 19 and SigmaPlot 10 will be used for these analyses.

Arm Intervention/treatment
Experimental: Treatment based on Movement System Impairment based model
Treatment based on Movement System Impairment based classification model is composed by patient education, analysis and modification of daily living activities and prescription of specific exercises
Other: Treatment based on Movement System Impairment model
The analysis and modification of daily activities will be performed by identifying and analyzing the patients activities that provoke their symptoms. The patient will be taught on how to correct his posture and limit the movements that increase the amount of stress on the lumbar spine. The prescription of specific exercises is done based on the patient's classification into one of 5 categories of the MSI model. These exercises consist of practicing the movement tests performed at the initial assessment in a corrected form, emphasizing the control of the lumbar spine movement and increasing movement on the adjacent joints. Patients will also advised to repeat the exercises at home at least once a day. 12 treatment sessions are planned for each patient (2 sessions per week during the first 4 weeks and 1 session per week during the last 4 weeks). Each treatment session has an estimated duration of 45-60 minutes. Patients will register their home exercise in an exercise diary.

Active Comparator: General exercise
The general exercise program consists of stretching exercises of the trunk and lower limbs muscles and strengthening exercises of the trunk muscles (Hayden et al., 2005; Rainville et al., 2004).
Other: General exercise
The general exercise program consists of 12 treatment sessions with estimated duration between 45-60 minutes per session (2 sessions per week for the first 4 weeks and 1 session per week in last 4 weeks). Each session is also done individually by a trained physical therapist. The patients perform an exercise program that starts with a 5-minutes warm-up followed by stretching exercises. Those stretching exercises address the six directions of lumbar motion and the lower limbs muscles. The patient also performs strengthening exercises of the trunk muscles. Based on correct performance of the exercises, the subject may progress through increased load as tolerated. He is also advised to perform these exercises at home and receive figures of the exercises with written instructions. The exercise program will be adapted according to American College of Sports Medicine recommendations (Garber et al., 2011). Patients will register their home exercise in an exercise diary.




Primary Outcome Measures :
  1. Pain Intensity [ Time Frame: 2 months after randomisation ]
    Pain Intensity will be measured by an 11-point (0-10) Numerical Rating Scale (Pain NRS)

  2. Disability [ Time Frame: 2 months after randomisation ]
    Disability will be measured by the 24-item Roland Morris Disability Questionnaire


Secondary Outcome Measures :
  1. Pain Intensity [ Time Frame: 4 and 6 months after randomisation ]
    Pain Intensity will be measured by an 11-point (0-10) Numerical Rating Scale (Pain NRS)

  2. Disability [ Time Frame: 4 and 6 months after randomisation ]
    Disability will be measured by the 24-item Roland Morris Disability Questionnaire

  3. Global perceived effect [ Time Frame: 2, 4 and 6 months after randomisation ]
    Global perceived effect will be measured by an 11-point (-5 to +5) Global Perceived Effect Scale
