 Group A which will include subjects with LBP, members of the research team will screen and attempt to consecutively enroll all patients who undergo assessment for low back pain at two clinical locations International Spine Pain Performance Center, and Synergy Manual Physical Therapy. The enrollment and baseline visit can occur at the same time. During enrollment each subject will privately be briefed on the purpose and involvement in the study and be allowed to ask questions and opt out if not interested. Informed consent will be reviewed and signed and each subject will be given a copy of the consent form 15 minutes. Since collection of baseline data outcome measures and ViMove Assessment is already considered standard clinical practice for subjects with low back pain at these clinical settings, providing informed consent would allow the researchers to access this information for purposes of the registry. A summary of the information collected at baseline will include: patient demographicsmedical history age, gender, pain episode duration, BMI, employment, marital status, comorbidities, co-interventions, ICD-10 LBP diagnosis, outcome measures LBP movement pattern classification, LBP Classifier Questionnaire, QVAS for back and leg, Oswestry Disability index, START-Keele, Fear Avoidance Behavior Questionnaire, EuroQol-5D, DASS-21, patient perception of movement contribution to pain 20 minutes, and an assessment ViMove standard assessment, 30 sec chair test, 40m walk test 25 minutes.
