This study is designed to monitor both physiological and patient self-report outcome variables. In addition, as there is little quantitative information on Spinal Manipulation Technique procedures reported in clinical trials, the study is designed to collect preliminary kinetic measures of the spinal manipulation technique delivery (i.e. force-time profiles).', 'detailedDescription': 'Participants with narrowly defined chronic low back pain will be included in this study. Each participant will be treated 12 times over the course of 6 weeks. The following data will be collected: participant characteristics that may predict outcome or be modifiers of force used by provider (gender, age, height, weight, and Body Mass Index); spinal segment load during the pre-load and thrusting phases (force and moment in the pre-load phase, peak load, and loading rate); physiological measures (posterior-anterior global stiffness and flexion-relaxation); patient-centered outcomes of back pain and function; and adverse events.\n\nStudy participants (n= 80) will be recruited from the Quad Cities metro area. A team of experienced chiropractic clinicians working at the Palmer Center for Chiropractic Research will treat study participants. Each of the study participants will receive 2 High Velocity Low Amplitude Spinal Manipulation treatment visits per week over a 6 week period. The physiological assessments will be performed immediately before and after Spinal Manipulation delivery during treatment visits 1, 5 \\& 12 (6 sets of assessments in total). During these same treatment visits, we will also capture the kinetic measures during Spinal Manipulation delivery for spinal segment load analysis. Participant patient-centered outcomes will be measured at baseline 1, and treatment visits 6 and 13. For simplicity, data collection time points will be named as baseline, after 2 weeks, and after 6 weeks.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '21 Years', 'healthyVolunteers': True, 'eligibilityCriteria': "Inclusion Criteria:\n\n* NRS score, AVERAGE within the past 24 hours\n* Must be ≥4 at the phone screen or baseline 1 visit\n* Must be ≥2 at phone screen, baseline 1 and baseline 2 visits\n* Roland Morris Disability ≥6\n* Age 21-65\n* Signed informed consent document\n* Chronic (12+ weeks) low back pain\n\nExclusion Criteria:\n\n* Compliance concerns\n* No manipulable lesion in L1-L5 or SI joints\n* The absence of typical palpatory characteristics as well as the absence of a global assessment that would indicate that spinal manipulation is likely to generate a positive therapeutic effect, even without the presence of standard palpatory findings\n* Ongoing treatment for low back pain by outside provider\n* Comorbid conditions\n* Serious concomitant illness\n* Inflammatory or destructive spinal tissue change\n* Ankylosing Spondylytis\n* Fibromyalgia\n* Rheumatoid Arthritis\n* Confirmed or suspected disc herniation with neurological signs\n* Neuromuscular disease (e.g. Parkinson's, Muscular Dystrophy, Cerebral Palsy, or Myasthenia gravis\n* Spinal surgery \\<6 months\n* Suspicion of drug or alcohol dependence or abuse\n* Uncontrolled hypertension\n* Lower extremity peripheral arterial disease\n* Undetermined, infections or visceral source of low back pain\n* Other comorbid conditions prohibiting treatment and/or testing\n* Safety concerns\n* Bleeding disorders\n* Contraindications to High Velocity Low Amplitude Spinal Manipulation\n* Inability to tolerate or obtain positon for flexion-relaxation test without condition aggravation\n* Inability to tolerate or perform/receive any study procedure without condition aggravation\n* Quebec Task Force (QTF) criterion 4-11:\n* QTF 4: Pain + radiation to upper/lower limb with neurologic signs\n* QTF 5: Presumptive compression of a spinal nerve root on a simple roentgenogram\n* QTF 6: Compression of a spinal nerve root confirmed by specific imaging techniques\n* QTF 7: Spinal Stenosis\n* QTF 8: Postsurgical status, 1-6 months after intervention\n* QTF 9: Postsurgical status, \\>6 months after intervention\n* QTF 10: Chronic pain syndrome\n* QTF 11: Other diagnoses\n* Pregnancy\n* Pacemaker or defibrillator\n* Inability to read or verbally comprehend English\n* Joint replacement\n* Use of spinal manipulation within past 4 weeks\n* Sensitivity to adhesive\n* Diagnostic procedures other than x-ray/UA necessary\n* BDI-II ≥29\n* Retention of legal advice and open or pending case related to low back pain\n* BMI ≥40\n* Unwilling to have low back and wrist shaved\n* Moving from Quad Cities area within next 8 weeks\n* Unwilling to postpone treatments for low back pain from another provider\n* Seeking or receiving compensation for any disability"}, 'identificationModule': {'nctId': 'NCT01670292', 'acronym': 'PRiSM', 'briefTitle': 'Patient Response to Spinal Manipulation', 'organization': {'class': 'OTHER', 'fullName': 'Palmer College of Chiropractic'}, 'officialTitle': 'Patient Response to Spinal Manipulation', 'orgStudyIdInfo': {'id': 'PRiSM Study'}, 'secondaryIdInfos': [{'id': 'U19AT004663', 'link': 'https://reporter.nih.gov/quickSearch/U19AT004663', 'type': 'NIH'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'OTHER', 'label': 'Experimental: HVLA-SM', 'description': 'Experimental High Velocity Low Amplitude Spinal Manipulation', 'interventionNames': ['Other: HVLA-SM']}], 'interventions': [{'name': 'HVLA-SM', 'type': 'OTHER', 'description': 'High Velocity Low Amplitude Spinal Manipulation', 'armGroupLabels': ['Experimental: HVLA-SM']}]}, 'contactsLocationsModule': {'locations': [{'zip': '52803', 'city': 'Davenport', 'state': 'Iowa', 'country': 'United States', 'facility': 'Palmer College of Chiropractic', 'geoPoint': {'lat': 41.52364, 'lon': -90.57764}}], 'overallOfficials': [{'name': 'Ting Xia, PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Palmer College of Chiropractic'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'YES', 'description': 'Once the resulting manuscripts have been published, data sets will be provided for public access.
