Nonspecific Low Back Pain (nonspecific + low_back_pain)
Selected AbstractsWhat Is the Relationship of Low Back Pain to Signs of Abnormal Skeletal Metabolism Detected by Bone Scans?PAIN MEDICINE, Issue 2 2008Brenda Breuer PhD ABSTRACT Background., In approximately 80,85% of patients with chronic nonspecific low back pain (NSLBP), a precise pathoanatomical diagnosis cannot be identified. Mechanisms of bone nociception may contribute to NSLBP. Objective., To determine whether findings on bone scans, which provide a pathophysiological picture of functional activity, are associated with self-reports of NSLBP intensity. Design., A cross-sectional study of the relationship of self-reported chronic NSLBP intensity to the uptake of radiolabeled technetium-99m-methylene diphosphonate in the lumbosacral area. Study Participants., Patients referred for bone scans who were at least 18 years old. Outcome Measures., Subject reports of pain intensity and intensity of uptake of radiolabeled technetium-99m-methylene diphosphonate in the lumbosacral area. Results., Among subjects who were 65 years or younger, the age-adjusted worst pain intensity accounted for 45% of the variability in the amount of tracer uptake (r = 0.67, P = 0.0006). The association was not significant for those older than 65 years. Conclusion., Further studies should be conducted on possible mechanisms relating bone nociception to chronic NSLBP in individuals who are 65 years or younger.

Weiner MD ABSTRACT Objectives., 1) To examine recent change in prevalence and Medicare-associated charges for non-invasive/minimally invasive evaluation and treatment of nonspecific low back pain (LBP); and 2) to examine magnetic resonance imaging (MRI) utilization appropriateness in older adults with chronic low back pain (CLBP). Design., Two cross-sectional surveys of 1) national (1991,2002) and Pennsylvania (2000,2002) Medicare data; and 2) patients aged ,,65 years with CLBP. Setting., Outpatient data. Participants., Patients aged , 65 years with LBP. Measurements., Study 1: Outpatient national and Pennsylvania Part A Medicare data were examined for number of patients and charges for all patients, and for those with nonspecific LBP. Total number of visits and charges for imaging studies, physical therapy (PT), and spinal injections was also examined for Pennsylvania. Study 2: 111 older adults with CLBP were interviewed regarding presence of red flags necessitating imaging and history of having a lumbar MRI, neurogenic claudication (NC), and back surgery. Results., Study 1: Between 1991 and 2002, there was a 42.5% increase in total Medicare patients, 131.7% increase in LBP patients, 310% increase in total charges, and 387.2% increase in LBP charges. In Pennsylvania (2000,2002), there was a 5.5% increase in LBP patients and 33.2% increase in charges (0.2% for PT, 59.4% for injections, 41.9% for MRI/CT, and 19.3% for X rays). Study 2: None of the 111 participants had red flags and 61% had undergone MRIs (29% with NC, 24% with failed back surgery syndrome). Conclusion., LBP documentation and diagnostic studies are increasing in Medicare beneficiaries, and evidence suggests that MRIs may often be ordered unnecessarily. Injection procedures appear to account for a significant proportion of LBP-associated costs. More studies are needed to examine the appropriateness with which imaging procedures and non-invasive/minimally invasive treatments are utilized, and their effect on patient outcomes.

[source] Prevalence of nonspecific low back pain in schoolchildren aged between 13 and 15 yearsACTA PAEDIATRICA, Issue 2 2008Stefano Masiero Abstract Aim: To investigate the annual (2005) prevalence of nonspecific low back pain (LBP), defined as lumbago not attributed to recognizable, known specific pathology, in a population of adolescents. Methods: We investigated 7542 school teenagers with a structured questionnaire consisting of demographic and anthropometric items, psychosocial factors and life style, presence and intensity of LBP, family history of LBP, and questions about whether the teenager had been referred to a physician for this problem. Univariate (t -test, Mann,Whitney U-test and chi-square test) and multivariate analyses (logistic regression) were performed. Results: A total of 1180 (20.5%) teenagers reported one or more episodes of LBP, of whom 900 (76.3%) had consulted a health provider. A significantly greater percentage of LBP was found in the students who practised aerobics and swimming compared to the other sports. The search for risk factors in the whole population revealed no associations between LBP and the investigated anthropometrics or lifestyle items, whereas a significant association was found for gender (to be female), positive family history of LBP and absence of sports activity. Conclusions: Our study shows that nonspecific LBP is a frequent event in teenagers, particularly in females, sedentary children and those with a family history of LBP. [source] | ||||||||||
