Analysis of Orthopedic Patients Response to New Pain Modulating Substances and Drugs
Low Back PainData of patient reported outcomes (PRO) are collected during treatment with various pain alleviation methods (drugs or substances)
Cytochrome P450 Pharmacokinetic DDIs Among Patients With Chronic Low Back Pain Taking Opioids
Chronic Low Back PainUsing a retrospective analysis of a large commercial claims database and a Medicare database, the investigators evaluated DDEs that have the potential to cause DDIs among chronic low back pain (cLBP) patients on long-term opioid analgesia, which metabolizes through the CYP450 enzyme system, concomitant with other CYP450-metabolized drug(s)
Preliminary Study of the Sagittal Alignment of the Lumbo-pelvic Complex in a Sitting Position
Back PainLow Back PainThe main objective of this study is to investigate the influence of seat type (straight chair versus "ergonomic" chair) on the sagittal alignment of the lumbo-pelvic complex in two different postures compared to standing for each individual in both a chronic-back-pain and a non-chronic-back-pain population.
Connective Tissue Motion Measure 2
Low Back PainMusculoskeletal PainThis study aims to compare the Connective Tissue Motion Measure (CTMM) in low back pain and no-low back pain subjects, evaluate the reliability of the CTMM, and examine the correlation of CTMM with low back pain symptoms, disability, and functional measures. The investigators hypothesize that CTMM will be reduced, on average, in low back pain subjects, that CTMM will be reliable with an intra-class correlation greater than 0.8, and CTMM will negatively correlate with low back pain symptoms, disability and functional measures.
Predictive Factors for LBP Interventional Treatment Outcomes
Low Back PainLumbar RadiculopathyIn this study, we are attempting to determine which factors are associated with interventional treatment outcome for LBP (and to what extent). Up to 346 patients with LBP who are considered to be good candidates for therapeutic interventional procedures will be given a complete history and physical exam, which includes the assessment of Waddell signs, and querying them regarding factors shown in non-interventional studies or retrospective studies evaluating interventional treatments to be associated with negative treatment outcomes. These factors include the presence of Waddell and other physical exam signs, opioid use, allergies, psychopathology, concomitant pain conditions, a 6-point Likert scale on expectations, sleep abnormalities, secondary gain (e.g. medical board or litigation), procedure-related pain including from a 1 ml standardized injection, obesity, and smoking history. They will then proceed to undergo their scheduled intervention, which will be limited to epidural steroid injections (ESI), facet blocks and if positive, radiofrequency denervation, and sacroiliac (SI) joint injections. A positive outcome will be defined as 2-point or greater decrease in average pain score at 1-month and a score of > 3 on a 1-5 Likert satisfaction scale. Those with a positive outcome at 1-month will remain in the study and be followed again at 3-months.
Prognostic Factors of Disabling Low Back Pain in Patients With Chronic Low Back Pain
Chronic Low Back PainMechanical Low Back PainThe aim of the present study is to quantify the relative contribution of variables obtained during a physical fitness evaluation and a short screening questionnaire in determining the short-term and long term risk of persistent disabling low back pain in patients with chronic low back pain. It has been hypothesized that patients with higher physical fitness will present a lower risk of persistent disabling low back pain and so, a lower score on the questionnaire.
The Healing Context in Complementary and Alternative Medicine (CAM): Initial Validation Study
Chronic Low Back PainNeck PainThe overall objective of this study is to develop and test an efficient set of self-report instruments to measure Complementary and Alternative Medicine(CAM)-relevant contextual factors important in healing. The initial phase of the study involves developing and refining an item bank. During the initial 'item bank development' phase, the investigators will run focus groups and cognitive interviews with individuals who participate in CAM and conventional medicine interventions. The next step of instrument development is called Calibration, and involves administering the revised item bank to an internet sample and to persons who receive services in a CAM clinic and a conventional primary care setting. The items will be calibrated using item response theory and classical test theory. This will result in a computerized adaptive testing version of the instrument, as well as a static short form of the instrument. This current protocol in ClinicalTrials.gov pertains only to the final, Validation Phase of the study. The final phase of the project will involve conducting initial validation studies of the set of instruments. The set of instruments will be called the Healing Encounters and Attitudes Lists (HEAL). The investigators will evaluate the convergent, discriminant, and predictive validity of the HEAL instruments in a sample of 200 persons with chronic low back pain or neck pain who are receiving physical therapy, chiropractic care, acupuncture, medical management, or mindfulness-based stress reduction. For convergent validity, the HEAL is expected to display moderate to large correlations with measures of similar constructs. The HEAL is expected to correlate modestly with self-report measures of general psychosocial functioning, in support of discriminant validity. Finally, HEAL scores should account for a significant proportion of the variance in treatment outcome, supporting predictive validity.
Study to Evaluate the Effectiveness of DRG Stimulation for Discogenic Low Back Pain
Discogenic Low Back PainThe purpose of this prospective post market observational pilot study is to evaluate the effect of DRG stimulation in the management of chronic discogenic pain in subjects who are refractory to other available treatments. Selected subjects will not be suitable candidates for lumbar spinal surgery and will meet the standard selection process for DRG stimulation as routinely utilised in the study centre. Results from this pilot study will inform current clinical practice and future comparative studies in this specific population.
Relationship in Sleep With Low Back Pain in Postmenopausal Period
Postmenopausal SymptomsIntroduction:The aim of this study was to investigate the incidence of low back pain in postmenopausal period and the relationship between low back pain and emotional state,sleep and quality of life i aimed at investigating low back pain during postmenopausal period of women and its correlation with the emotional state,sleep quality and the quality of life of woman. Method:This cross-sectional study was conducted in 368 postmenopausal women aged between 40 and 65 years.All participants were recorded frequency and severity of low back pain,depressive symptoms and anxiety,quality of life and sleep quality.Outcome measures are described in more detail below.
Predicting Response to Interventional Pain Management Techniques in Chronic Low Back Pain in a Prospective...
Low Back PainPain Measurement5 moreThe main aim of this study is to identify factors that may be associated with a better or worse response to interventional pain management therapies for the treatment of chronic lumbar pain in adult patients. If several predictive factors are to be identified, a predictive model will be developed.
