Abstract Purpose: To systematically explore how disability is influenced with layers　(demographic level, pain level and psychosocial factors) in nonspecific low back pain (NSLBP) in different subgroups.Methods: This is a cross-sectional study that compared two different subgroups in NSLBP at two hospitals. Hierarchical multiple regression analysis was performed to analyse factors affecting disability in different groups (overall group, acute group and subacute/chronic group).Results: In the overall group (n = 235), explanatory power increased with each additional variable in the order of demographic characteristics, pain intensity and psychosocial factors. Pain intensity (ß = 0.219), Pain Catastrophising Scale (PCS) (ß = 0.175) and Pain Self-Efficiency Questionnaire (PSEQ) (ß = −0.370) were significantly associated with disability. In the acute group (n = 65), explanatory power improved with each additional variable for the disability in the order of demographic characteristics, pain intensity and psychosocial factors. Ultimately, pain intensity and PSEQ had significant explanatory power, with pain having the most influence. However, in the subacute/chronic group (n = 170), explanatory power increased with each additional variable in the order of demographic characteristics, pain intensity and psychosocial factors and all, including psychosocial factors, had a strong impact, with self-efficacy having the most substantial impact on disability.Conclusion: Depending on the duration of the disease, the factors affecting the disability differed, with pain having more influence than psychosocial factors in the acute phase and psychosocial factors having more influence in the chronic phase.

AbstractThis study aimed to explore factors associating with disability, which means physical impairment affecting a person’s mobility, capacity, stamina, or agility, of non-specific low back pain (NSLBP) of the acute and non-acute groups. Two hundred thirty-five patients with NSLBP of less than 8 weeks’ duration as acute groups (n = 124) and more than 8 weeks’ duration as non-acute group (n = 111) were recruited. It was collected data on pain intensity, disability and psychosocial factors, including pain catastrophising, fear of movement and pain self-efficacy. Disability was measured Roland Morris Disability Questionnaire. A hierarchical multiple regression analysis was performed to analyse factors associating with disability of the acute and non-acute groups. The Result was that explanatory power increased with each additional variable of the order of demographic characteristics, pain intensity and psychosocial factors for both groups. Pain intensity, pain catastrophising and pain self-efficacy had significant explanatory power, with pain self-efficacy having the most significant association on the acute group. Only pain self-efficacy having the most significant association on disability of the non-acute group. In conclusion, the factors associating with disability differed depending on the duration of the disease, and pain self-efficacy might be one of the factors associating with disability of patients with NSLBP.

Factors Affecting

The purpose of this article is to investigate and model retail consumer purchase behavior and determine factors affecting the purchasing decision. The following hypotheses were verified: H1 tests the influence of “Decision-making Time” over “Final Purchase”. H2 tests “Promotion” over “Final Purchase”. H3, H4 and H5 were established to test the influence of demographic characteristics (respectively: Age, Nationality, Gender) over “Final Purchase”. SPSS 23 was used to analyze the collected data from the observations completed in the supermarket. In order to identify the explanatory power of the variables, a Logistic Regression model was developed. Empirical findings indicated that demographic characteristics (Age, Nationality, Gender), as well as “Time” and “Promotion,” have a significant effect on “Purchase” and that “Time” has a greater impact on “Purchase.” These results could be used to design marketing strategies in order to increase sales. However, a few limitations occurred during the study such as observation timing, the unicity of location and observers' subjectivity.

Abstract Background and Purpose. Physical and psychosocial factors are hypothesized to influence performance-based assessment. The purpose of this study was to evaluate the association between performance on the Isernhagen Work System Functional Capacity Evaluation (IWS-FCE) and various clinical and psychosocial factors. Subjects. The sample consisted of 170 workers' compensation claimants who were undergoing functional capacity evaluations (FCEs) for low back injuries. Methods. In this cross-sectional study, claimants completed a battery of work-related measures, including the IWS-FCE, the Pain Disability Index (PDI), a workplace organizational policies and practices scale, and a recovery expectations questionnaire. Functional capacity evaluation performance indicators were the number of tasks in which subjects did not meet work demands and weight lifted on the floor-to-waist lift. Analysis included multivariable regression. Results. Only the PDI, pain intensity, age, and sex independently contributed to floor-to-waist lift performance. The PDI, pain intensity, and duration of injury contributed to the number of failed tasks. Discussion and Conclusion. The results indicate that performance on FCEs is influenced by physical factors, perceptions of disability, and pain intensity. However, perceptions of workplace organizational policies and procedures were not associated with FCE results for workers' compensation claimants with chronic back pain disability. Functional capacity evaluations should be considered behavioral tests influenced by multiple factors, including physical ability, beliefs, and perceptions.

Mohammad Hoesin Palembang. Lumbar disk herniation (LDH) is the most common disease that becaused low backpain and functional disability. Some studies mentioned that hydrotherapy is an effective treatment for low back pain.Therefore, this study was conducted to determine the effect of hydrotherapy on reducing pain intensity and improvingfunctional ability in LDH patients. This study was a pre-experimental study with one group pretest-posttest design. Datawas collected by direct interviews to the patients using visual analogue scale (VAS) to measure pain intensity andModified Oswestry Low Back Pain Disability Questionnaire to assess functional ability before and after underwenthydrotherapy once a week for 4 weeks. The data then undergo Shapiro-Wilk normality test and continue with Paired t-Test or Wilcoxon test. From 30 subjects, it was found that there are effects of hydrotherapy on reducing pain intensity(p<0,001) and improving functional ability (p<0,001) in LDH patients that undergo non-operative procedure at theMedical Rehabilitation Installation of RSUP Dr. Mohammad Hoesin Palembang. There are effects of hydrotherapy onpain intensity and functional ability in LDH patients that undergo non-operative procedure.

The article performed the processing of the results of a computer experiment to determine the cooling time of oil in a stopped oil pipeline. We proposed a calculation model in previous works that allows you to simulate the process of cooling oil.There was a need to verify the previously obtained results when conducting a laboratory experiment on a stand with soil. To conduct the experiment, it was necessary to conduct the planning of the experiment. The factors affecting the cooling time of oil in the oil pipeline, which will vary in the proposed experiment, are determined, empirical relationships are established. A regression analysis was carried out, and the dispersion homogeneity was checked using the Cochren criterion. The estimates of reproducibility variances are calculated. The adequacy hypothesis was tested using the Fisher criterion. Significant regression coefficients are established.
