There occurs to be a wash out effect because of the heterogeneous character of CLBP patients. As a result, no effect can be demonstrated for the entire sample. This is why one should consider creating subgroups based on prognostic indicators.\n\nObjectives for this trial is to possibly identify prognostic indicators for treatment response to three forms of exercise therapy for patients with nonspecific chronic low back pain (CLBP).\n\nThe study design is a multicenter cohort design. Patients with nonspecific low back pain of more than three months duration are recruited in two different hospitals (Antwerp University Hospital and Sint Vincentius Hospital). After examination patients are assigned to one of three intervention groups: motor control therapy, isometric training therapy and a combination therapy. All patients will undergo eighteen treatment sessions during nine weeks. Measurements will be taken at baseline and after nine weeks of treatment.\n\nThe primary outcome used is the Modified Oswestry Disability Questionnaire (MDQ). For each type of exercise therapy prognostic indicators will be investigated.\n\nNever before a multi-arm design was performed for the identification of prognostic indicators for exercise therapy in patients with nonspecific CLBP.', 'detailedDescription': 'Methods/ Design\n\nEthical approval (B300201215600) was obtained from the local ethics committees of the Antwerp University Hospital.\n\nStudy design In the identification of prognostic indicators is derived from a number of variables that have predictive potential for therapy outcome. These variables are obtained from baseline measurements and have a multidimensional character (impairments, activities/participation and contextual factors).\n\nPatient recruitment Patients will be recruited by doctors at the service of two settings located in Antwerp namely the Antwerp University Hospital (UZA) and the Sint-Vincentius Hospital. Treatment and measurements will be performed at the site where the patient has been recruited.\n\nInclusion criteria: Current nonspecific LBP persisting at least three months, consulted a medical doctor during the last month because of the persistent low back pain, age between 18 and 60, sufficient fluency in Dutch to follow treatment instructions and answer survey questions.\n\nExclusion criteria: spinal canal stenosis, spondylolisthesis and spondylitis, large herniated disc sciatica, radiating pain below the knee, previous back surgery, a history of known spinal fractures, malignancy, known muscle-, nerve-, skin-, or joint diseases, pregnancy and lack of consent.\n\nMeasurements\n\nBaseline testing As primary (dependent) outcome measure the Modified Oswestry Disability Questionnaire is used (MDQ). The MDQ is a disease specific questionnaire to measure disability in LBP patients \\[21-23\\].\n\nAs secondary (independent) outcome measures the following tests are used:\n\nFirst, Measurement of impairments: duration of the LBP/ pelvis impairments / respiratory impairments (all three items through anamnesis). Prone instability test, Straight Leg Raise, Beighton scale, Active Straight Leg Raise, sitting knee extension test, waiters bow, pelvic tilt, side support test, extensor endurance test, active sit-up, Visual Analogue Scale for pain (VAS).\n\nSecond, measurement of limitations in activities and participation: hours of physical activity/week (trough anamnesis). Short Form 36 Health Survey (SF36), Roland Morris Disability Questionnaire (RMDQ).\n\nThird, measurement of contextual factors: gender/ age / height / weight / body mass index / smoking / profession / underwent previous therapy / comorbidity (trough anamnesis). Tampa scale for kinesiophobia, Fear Avoidance Belief Questionnaire (FABQ), We performed a literature search to select all used clinical tests based on their reliability and validity \\[24\\]. The Baseline testing takes about 30 minutes.\n\nFollow-up\n\nFollow up takes place after completion of the treatment program at nine weeks. All patient reported outcome measures (PROMs) from the baseline testing will be re-evaluated at this moment.\n\nRandomization \\& blinding\n\nIn the Sint-Vincentius Hospital, all included patients will follow the combination treatment since this is the only intervention group which is being organized in this hospital.\n\nIn the UZA, patients will be randomly assigned into one of the two treatment groups (motor control or isometric training) after baseline testing. The responsible researcher will use a randomization list generated with Microsoft ® Excel ® software (version 14.3.9, 2010 © Microsoft Corporation).\n\nIntervention\n\nDuring the nine weeks intervention, patients will be treated two times a week. Patients will be assigned randomly into one of three intervention groups (motor control therapy, isometric training therapy or combination therapy). Each intervention will take about seventy minutes. Ten minutes warming up and cooling down will be the same in each treatment regime. Each group receives fifty minutes of therapy specific intervention. Previously trained physiotherapists will give the treatment. To ensure that all therapists provide the same exercises, a treatment protocol for each treatment group was developed and a treatment diary will be filled out after each session.\n\nInterventions in derivation and validation phase are similar.\n\nPower analysis\n\nThis study describes the identification of prognostic indicators in which the therapeutic effect of the interventions cannot be predicted. Therefore, a two-tailed hypothesis was used to calculate the power. A pilot study showed that the standard deviation of the primary outcome measure, MDQ, is set at 10.53.6 Given these estimates, 54 patients were needed to detect a minimum clinically important difference (MCID, effect size 0.84) with 90% power. Consequently, three groups of 18 patients were needed to complete the trial.\n\nData analysis\n\nPrognostic indicators aim to detect potential predictive variables for treatment success (dichotomous, yes/no) in a set of baseline measurements. A minimal decrease in the MDQ score of 9 points is considered as treatment success.\n\nPotential predictive variables are selected as follows: first, individual variables from the self-reports, history, and physical examination are tested for their bivariate association with the reference standard using independent sample t tests, Mann-Whitney U tests or Chi-square tests based on the nature of the data. Variables with a significance level of P \\< 0.10 are retained as potential prediction variables. We choose a more liberal significance level at this stage to avoid excluding potential predictive variables.\n\nThis statistical analysis is performed for each treatment group (motor control therapy, general active exercise therapy and isometric training therapy).\n\nInformation form and informed consent\n\nIf patients meet the in- and exclusion criteria they are scheduled for an interview with one of our researchers to be informed about the trial. If patients decide to participate they will sign an informed consent. Information form and informed consent are made and have been approved by the ethics committee of the University of Antwerp.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '60 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* at least 3 months low back pain\n* consulted a medical doctor during last month because of persistent low back pain\n* age between 18 - 60\n\nExclusion Criteria:\n\n* vestibular dysfunction\n* a history of known spinal fractures\n* spondylolysis and spondylolisthesis\n* radiating pain below the knee\n* muscle, nerve, skin, joint diseases\n* pregnancy'}, 'identificationModule': {'nctId': 'NCT02063503', 'briefTitle': 'Identification of Prognostic Indicators for Rehabilitation in Chronic Nonspecific Low Back Pain Patients', 'organization': {'class': 'OTHER', 'fullName': 'Universiteit Antwerpen'}, 'officialTitle': 'The Identification of Prognostic Indicators for Exercise Therapy in Patients With Nonspecific Chronic Low Back Pain: A Multicenter Trial', 'orgStudyIdInfo': {'id': 'B300201215600'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Motor control therapy', 'description': 'physiotherapy', 'interventionNames': ['Other: physiotherapy']}, {'type': 'EXPERIMENTAL', 'label': 'Isometric training therapy', 'description': 'physiotherapy', 'interventionNames': ['Other: physiotherapy']}, {'type': 'EXPERIMENTAL', 'label': 'Combination therapy', 'description': 'physiotherapy', 'interventionNames': ['Other: physiotherapy']}], 'interventions': [{'name': 'physiotherapy', 'type': 'OTHER', 'otherNames': ['- Motor control therapy', '- Isometric training devices', '- Combination therapy'], 'description': 'every group receives 2 treatments every week during 9 consecutive weeks', 'armGroupLabels': ['Combination therapy', 'Isometric training therapy', 'Motor control therapy']}]}, 'contactsLocationsModule': {'locations': [{'zip': '2650', 'city': 'Edegem', 'state': 'Antwerpen', 'status': 'RECRUITING', 'country': 'Belgium', 'contacts': [{'name': 'Lenie Denteneer, Dra, Pt', 'role': 'CONTACT', 'email': 'lenie.denteneer@uantwerpen.be', 'phone': '0032494884189'}, {'name': 'Ulrike Van Daele, Prof, Pt, Mt', 'role': 'CONTACT', 'email': 'ulrike.vandaele@uantwerpen.be', 'phone': '003236418265'}, {'name': 'Lenie Denteneer, Dra, Pt', 'role': 'PRINCIPAL_INVESTIGATOR'}], 'facility': 'Universitair Ziekenhuis Antwerpen', 'geoPoint': {'lat': 51.15662, 'lon': 4.44504}}], 'centralContacts': [{'name': 'Lenie Denteneer, phd student', 'role': 'CONTACT', 'email': 'lenie.denteneer@uantwerpen.be', 'phone': '0032494884189'}, {'name': 'Ulrike Van Daele, Professor', 'role': 'CONTACT', 'email': 'ulrike.vandaele@uantwerpen.be', 'phone': '003236418265'}], 'overallOfficials': [{'name': 'Ulrike Van Daele, Professor', 'role': 'STUDY_DIRECTOR', 'affiliation': 'Universiteit Antwerpen'}, {'name': 'Gaetane Stassijns, Professor', 'role': 'STUDY_DIRECTOR', 'affiliation': 'Universiteit Antwerpen, Universitair Ziekenhuis Antwerpen'}, {'name': 'Lenie Denteneer, phd student', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Universiteit Antwerpen'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'UNDECIDED'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Universiteit Antwerpen', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Dra.
