Burden of pain in back and extremities in rural population: A community-based estimation of 12-month prevalence, distribution and duration of pain in rural Gadchiroli, India.

ABSTRACT: Background:Population based estimates of the burden of pain in back and extremities (PBE) are lacking from rural India. We estimated this burden, measured as a) 12-month prevalence, b) site specific prevalence c) total number of painful sites per adult, d) severity of pain and e) duration of pain in the rural adult population in Gadchiroli, India, over a period of 12 months. Methods:This population-based, cross-sectional study was conducted in two villages randomly selected from a cluster of 7 eligible villages in Gadchiroli district of India. All adults ≥20 years in these villages were surveyed by the trained community health workers in January 2010 by making household visits. The data were collected using a structured, pretested questionnaire on the history of pain in back and extremities (PBE) at various anatomical sites and its features during the previous 12 months. Results:Out of 2535 eligible adults in two villages, 2259 (89%) were interviewed, of which 1876 (83%) had an episode of PBE in the preceding 12 months. The period prevalence of pain was 76% in back (including lower back, thoracic and neck) and 71% in the extremities. Highest site specific prevalence was at lower back (70%), knee (46%), neck (44%), leg/calf (39%) and mid-back (39%). The mean number of painful sites per adult was 4.57 (standard deviation (SD) = 4.17). The prevalence of severe pain was 15%. The mean number of painful days due to PBE was 166 days. Female gender (odds ratio (OR) = 2.8, 95% confidence interval (CI) = 2.1-3.6), farming/labour occupation (OR = 1.8, 95% CI = 1.4-2.4), increasing age (more than 60 years OR = 6.3, 95% CI = 3.3-11.9) were significantly associated with the risk of PBE. Conclusion:Nearly five out of six adults in rural Gadchiroli suffered from pain in back or extremities during the preceding 12 months. Pain was at multiple sites and was present on a mean 166 days in the year. Female gender, farming / manual labor as occupation and increasing age were the key risk factors identified. The pain in back and extremities emerges as a public health priority in rural communities.

Project description:BackgroundPopulation based estimates of the extent of the activity limitation due to back pain and disability due to musculoskeletal pains are lacking from rural India. We estimated this burden as a) extent of activity limitation due to back pain, b) disability due to musculoskeletal pains, c) grading of the limitation of each activity due to back and musculoskeletal pain in the rural adult population in Gadchiroli, India.MethodsThis population-based, cross-sectional study was conducted in two villages randomly selected from a cluster of 7 eligible villages in Gadchiroli district of India. All adults ≥20 years in these villages were surveyed by the trained community health workers in January 2010. Disability due to back pain was evaluated using newly developed questionnaire for women and men which assessed limitations in the gender-specific daily household and occupational activities in a rural area. Disability due to pain in extremities was assessed using the Health Assessment Questionnaire (HAQ).ResultsThe total population of the two villages was 3735 out of which 2535 (67.9%) were adults ≥20 years of age and were eligible to participate in the study. Of these, 2259 (89%) were interviewed and 1247 participants (55%) had any pain on the day of the survey. Activity limitation questionnaire was filled for 716 (91.4%) out of 783 patients with back pain. HAQ scale was filled for 524 (85.2%) out of 615 patients with pain in extremities. Among men with back pain, respectively 11%, 19%, 60% and 11% had no, mild, moderate to severe difficulty or were completely unable to perform agrarian work, while among women, respectively 6%, 20%, 69% and 4% had no, mild, moderate to severe difficulty or were completely unable to perform household activities. Based on the HAQ score, respectively 1%, 67%, 18% and 14% of the participants had no, mild, moderate to severe disability or were completely unable to perform the activities.ConclusionsThis community-based study in rural Gadchiroli demonstrates significant mild to moderate disability and activity limitation, due to pain in back and extremities in a population involved in hard manual work, especially agricultural and underlines the need to address the problem through appropriate interventions. The study also employs for the first time an indigenously developed questionnaire to identify activity limitation due to back pain, and demonstrates the method as well as the questionnaire.

Project description:PurposeAdults with diabetes mellitus (DM) suffer often from chronic pain, yet evidence-based interventions for comorbid pain and DM are scarce. We tested the effect of a peer-led cognitive behavioral training (CBT) intervention on pain self-efficacy (PSE), pain intensity, and pain-related functional limitations (PRFL) in adults with DM, 1 year after trial initiation.MethodsThe yearlong "Living Healthy" cluster-randomized trial included 230 residents of rural Alabama with DM, who reported pain in the past month; communities were treated as clusters. Intervention participants received a peer-delivered 8-session structured CBT intervention in the context of diabetes self-management; attention control arm participants received a peer-delivered 8-session general health education program. Outcomes included PSE (Arthritis Self-Efficacy Scale, range 10-100); pain intensity (McGill Pain Questionnaire, range 0-45); and PRFL (Western Ontario and McMaster Universities Osteoarthritis Index scale, range 0-100). We examined control-intervention differences in changes in outcome scores from baseline to 3-month and 12-month follow-up, adjusted for clustering.FindingsThe 195 participants with follow-up data were aged 59 ± 10.4 years, 96% were African American, 79% were women, and 80% reported pain on the day of baseline data collection. At 3-month follow-up, PSE increased more for intervention (21-point increase) than control (5-point increase) participants (P for control-intervention (C-I) difference in change < .001); pain intensity decreased for both groups; and PRFL decreased only for intervention participants (-11 score; P for C-I difference in change < .001). Results were sustained at 12 months, and pain intensity significantly improved in only the intervention arm (P for C-I difference in change = .01).ConclusionsThis peer-delivered CBT intervention improved pain self-efficacy, pain-related functional limitations, and pain intensity over 12 months among rural participants with DM and chronic pain.

Project description:BackgroundStratification strategies based on identifying patient's prognosis in order to guide patient care constitute one of the most prominent and recent approach in low back pain research. The STarT Back Screening Tool (SBST) although promising, has not been studied in patients with chronic low back pain (cLBP). Considering how challenging it is to translate research into practice, the value of integrating a new tool should be thoroughly assessed. The purpose was therefore to assess associations between the short- and long-terms clinical status and two types of variables, physiologic measures and the SBST, in participants with cLBP. The ability of both types of variables to discriminate between participants with and without higher levels of disability, pain, fear of movement and patient's global impression of change was also investigated.MethodsFifty-three volunteers with cLBP participated in an initial evaluation and follow-ups at 2-, 4-, 6- and 12-month. Physiologic measures (maximal voluntary contraction, maximal endurance and muscle activity evaluated during prone and lateral isometric tasks) and the SBST were assessed at baseline. Disability (Oswestry Disability Index, ODI), pain intensity (101-point Numerical Rating Scale, NRS), fear of movement (Tampa Scale for Kinesiophobia, TSK) and patient's global impression of change (7-point scale, PGIC) were evaluated at baseline and at each follow-up. Aside the use of correlation analyses to assess potential associations; ROC curves were performed to evaluate the discriminative ability of physiologic measures and the SBST.ResultsThe SBST allowed for the identification of participants presenting higher levels of disability (ODI ≥24 %), pain (NRS ≥37 %) or fear of movement (TSK ≥41/68) over a 12-month period (AUC = 0.71 to 0.84, ps < 0.05). The SBST score was also correlated with disability at each follow-up (τ = 0.22 to 0.33, ps < 0.05) and with pain intensity and fear of movement at follow-ups. Among physiologic measures, only maximal voluntary contraction was correlated to disability, pain intensity or fear of movement during the follow-up (|τ| = 0.26 to 0.32, ps < 0.05) and none was able to identify participants presenting higher levels of outcomes (AUC ps > 0.05).ConclusionPhysiologic measures obtained during prone and lateral tests have limited associations with the clinical status over a 12-month period in patients with nonspecific chronic low back pain. On the other hand, the STarT Back Screening Tool is useful for the identification of patients who will present higher levels of disability, pain intensity and fear of movement over a year.Trial registrationClinicaltrials.gov NCT02226692.

Project description:IntroductionVertebral endplates, innervated by the basivertebral nerve (BVN), are a source of chronic low back pain correlated with Modic changes. A randomized trial comparing BVN ablation to standard care (SC) recently reported results of an interim analysis. Here, we report the results of the full randomized trial, including the 3-month and 6-month between-arm comparisons, 12-month treatment arm results, and 6-month outcomes of BVN ablation in the former SC arm.MethodsProspective, open label, 1:1 randomized controlled trial of BVN ablation versus SC in 23 US sites with follow-up at 6 weeks, 3, 6, 9, and 12 months. SC patients were re-baselined and followed up for 6 months post BVN ablation. The primary endpoint was the between-arm comparison of mean Oswestry Disability Index (ODI) change from baseline. Secondary endpoints were Visual Analog Scale (VAS), Short Form (SF-36), EuroQual Group 5 Dimension 5-Level Quality of Life (EQ-5D-5L), responder rates, and rates of continued opioid use.Results140 were randomized. Results from BVN ablation (n=66) were superior to SC (n=74) at 3 months for the primary endpoint (mean ODI reduction, difference between arms of -20.3 (CI -25.9 to -14.7 points; p<0.001)), VAS pain improvement (difference of -2.5 cm between arms (CI -3.37 to -1.64, p<0.001)) and quality of life outcomes. At 12 months, basivertebral ablation demonstrated a 25.7±18.5 point reduction in mean ODI (p<0.001), and a 3.8±2.7 cm VAS reduction (p<0.001) from baseline, with 64% demonstrating ≥50% reduction and 29% pain free. Similarly, the former SC patients who elected BVN ablation (92%) demonstrated a 25.9±15.5 point mean ODI reduction (p<0.001) from baseline. The proportion of opioid use did not change in either group (p=0.56).Discussion/conclusionBVN ablation demonstrates significant improvements in pain and function over SC, with treatment results sustained through 12 months in patients with chronic low back pain of vertebrogenic origin.

Project description:ObjectiveThe objective of this study was to investigate whether poor hip range of motion (ROM) and strength predict 12-month physical function decline among older adults with chronic low back pain (LBP) and whether hip osteoarthritis modifies those relationships.MethodsAt baseline, passive ROM and strength measurements were taken for hip flexion, extension, abduction, adduction, internal rotation, and external rotation; ultrasound images and self-reported symptoms were used to evaluate hip osteoarthritis presence (eg, osteophytes and hip pain). At baseline and 12 months, performance-based (repeated chair rise, self-selected gait speed, 6-minute walk test [6MWT]) and self-reported (Quebec LBP Disability Questionnaire, Late-Life Function & Disability Instrument [LLFDI] basic and advanced lower extremity scales) physical function outcomes were assessed. Regression models were constructed for each outcome predicted by baseline hip ROM and strength measures, with adjustment for potential covariates. To avoid collinearity, hip ROM and strength measures with the strongest unadjusted correlations were included in final models. The hip osteoarthritis presence by hip ROM/strength interaction was also explored.ResultsHip abduction strength predicted repeated chair rise (β = -0.297, P < 0.001), gait speed (β = 0.160, P = 0.003), 6MWT (β = 0.159, P ≤ 0.001), Quebec LBP Disability Questionnaire (β = -0.152, P = 0.003), and LLFDI basic lower extremity scale (β = 0.171, P = 0.005) outcomes. Regarding hip ROM, extension predicted repeated chair rise (β = -0.110, P = 0.043) and LLFDI advanced lower extremity scale (β = 0.090, P = 0.007) outcomes, external rotation predicted gait speed (β = 0.122, P = 0.004) outcomes, and abduction predicted LLFDI basic lower extremity scale (β = 0.114, P = 0.026) outcomes. The hip osteoarthritis interaction was not significant for any model.ConclusionReduced hip strength and ROM predict physical function decline; hip osteoarthritis presence may not modify these relationships.

Project description:ObjectiveThe purpose of this study is to identify geriatric chronic low back pain (LBP) subgroups based on the presence of potentially modifiable hip impairments, using Latent Variable Mixture Modeling (LVMM), and to examine the prospective relationship between these subgroups and key outcomes over time.MethodsBaseline, 3-month, 6-month, and 12-month data were collected from a prospective cohort of 250 community-dwelling older adults with chronic LBP. Comprehensive hip (symptoms, strength, range of motion, and flexibility), LBP (intensity and disability), and mobility function (gait speed and 6-Minute Walk Test) examinations were performed at each timepoint. Baseline hip measures were included in LVMM; observed classes/subgroups were compared longitudinally on LBP and mobility function outcomes using mixed models.ResultsRegarding LVMM, a model with 3 classes/subgroup fit best. Broadly speaking, subgroups were differentiated best by hip strength and symptom presence: subgroup 1 = strong and nonsymptomatic, subgroup 2 = weak and nonsymptomatic, and subgroup 3 = weak and symptomatic (WS). Regarding longitudinal mixed models, all subgroups improved in most outcomes over time. Specifically, over 12 months, the nonsymptomatic subgroups had lower LBP intensity and disability levels compared with the WS subgroup, whereas the strong and nonsymptomatic subgroup had better mobility function than the 2 "weak" subgroups.ConclusionThese subgroup classifications may help in tailoring specific interventions in future trials. Special attention should be given to the WS subgroup given their consistently poor LBP and mobility function outcomes.ImpactAmong older adults with chronic low back pain, there are 3 hip subgroups: "strong and nonsymptomatic," "weak and nonsymptomatic," and "weak and symptomatic." People in these subgroups demonstrate different outcomes and require different treatment; proper identification will result in tailored interventions designed to benefit individual patients. In particular, people in the WS subgroup deserve special attention, because their outcomes are consistently poorer than those in the other subgroups.
