Little evidence links emotional labor to either psychological or physical health. This study determined whether the two types of emotional labor (i.e., surface vs. deep acting) were significantly associated with depressive symptoms and work-related musculoskeletal disorders in call center workers. A cross-sectional study was conducted with 274 workers recruited from a call center in Seoul, South Korea. In adjusted regression models, levels of surface, but not deep, acting were significantly and positively associated with depressive symptoms. Higher surface acting levels were significantly and positively associated with low back pain; higher deep acting levels were significantly and inversely associated with low back pain. Study findings could inform occupational health nurses as they delineate differentiated strategies, according to the nature of surface and deep acting, to promote psychological and physical health in call center workers.

AbstractIn screening the majority of job applicants, most of this nation's railroads administer a low-back X-ray examination in an attempt to ascertain the likelihood that the applicant will sustain future work-related low-back pain or injury. Many applicants are rejected for employment on the basis of the X-ray findings. The railroads apparently perceive this screening program as a cost-effective means (1) of decreasing the incidence of compensation claims for work-related injuries, brought against the rail-roads under the Federal Employers' Liability Act (FELA), (2) of reducing the number of lost workdays resulting from low-back pain or injury, and (3) of protecting particularly susceptible workers from job-related hazards.The authors of this Article submit that low-back X-ray examinations are poor predictors of future low-back pain or injury. They assert that the railroads' use of such examinations misclassifies a substantial number of job applicants as being at increased risk for such pain or injury, and, in consequence, unfairly denies them employment. Furthermore, the authors claim, the screening program has other negative consequences. For example, applicants rejected for railroad employment on the basis of X-ray findings may as a result have difficulty finding jobs in other industries. In addition, they state, there is a potential radiation hazard to examinees. Moreover, both the railroads and those applicants accepted for employment may inappropriately be reassured by normal findings.On balance, the authors conclude, the screening program has a negative social value. The authors suggest that the program, in effect, erroneously labels many applicants as handicapped, and then denies them employment. Such persons might have legal recourse under federal and state statutes prohibiting employment discrimination against the handicapped.

Physiotherapy practice involves the performance of strenuous physical activities related to the delivery of patient rehabilitation.  No evidence of studies relating to physiotherapy work-related low back pain (WRLBP) in South Africa could be found.  The aims of this study were to retrospectively investigate the incidence of work related low back pain among currently practicing physiotherapists in Bloemfontein, to determine the contributing risk factors, and to determine the responses of the physiotherapists to injury. Eighty four physiotherapists participated in this descriptive study. The results indicated that 67% of respondents had experienced work related low back pain and the 95% confidence interval for the incidence of WRLBP among physiotherapists in Bloemfontein is [56.8%; 76.6%].  Therapists performing cardio-thoracic related tasks had the most significant confidence interval of WRLBP [2.2%; 35.1%]. Fifty eight percent of respondents who had WRLBP reported that their symptoms were exacerbated by clinical practice.  The results of the study suggest that it is the nature of the job design which predisposes physiotherapists to injury and not a lack of kinetic handling knowledge. Further research is needed to develop methods to reduce the risks of WRLBP which are inherently part of physio-therapy practice.

Background: Non-specific low-back pain (NSLBP) is a common health problem worldwide, but the perception and coping strategies used by patients are underreported. Objectives: The objectives of the study were to evaluate the perception of patients with NSLBP, the ways the pain interrfered with their basic life, and coping strategies employed by them. Methods: Twenty patients consisting of 10 males (50%) and 10 females (50%) participated in this study. A qualitative interview was conducted using a three-section modified structured interview guide by Gwenda. Section A contained sociodemographic information, section B was the numerical pain rating scale, and section C asked questions about the pain duration, the ways of pain interference with the patient’s life, and strategies used to cope with pain. The data were analyzed using thematic content analysis. Results: The results showed that 50% of the patients were within the age range of 58 years or above. Ten (50%) patients perceived that NSLBP was caused by work-related activities and 10% perceived that NSLBP was a spiritual problem. Fifty percent reported that the pain interfered with their activities of daily living, and four (20%) mentioned that NSLBP interfered with their sexual function and religious activities. Concerning the coping strategy, 40% used prayer, 15% usually ignored the pain, and 35% used the conventional approach. Conclusions: It can be concluded that half of the patients with NSLBP perceived NSLBP to be caused by work-related activities. Besides, NSLBP interfered with basic activities of daily living, and about 40% were coping with NSLBP with prayer and spiritual means.

Background: Lumbar facet joints are a well recognized source of low back pain and referred pain in the lower extremity in patients with chronic low back pain. Conventional clinical features and other non-invasive diagnostic modalities are unreliable in diagnosing lumbar zygapophysial joint pain. Controlled diagnostic studies with at least 80% pain relief as the criterion standard have shown the prevalence of lumbar facet joint pain to be 16% to 41% of patients with chronic low back pain without disc displacement or radiculitis, with a false-positive rate of 17% to 49% with a single diagnostic block. Study Design: A systematic review of the diagnostic accuracy of lumbar facet joint nerve blocks. Objective: To determine and update the diagnostic accuracy of lumbar facet joint nerve blocks in the assessment of chronic low back pain. Methods: A methodological quality assessment of included studies was performed using Quality Appraisal of Reliability Studies (QAREL). Only diagnostic accuracy studies meeting at least 50% of the designated inclusion criteria were utilized for analysis. Studies scoring less than 50% are presented descriptively and analyzed critically. The level of evidence was classified as good, fair, and limited or poor based on the quality of evidence developed by the United States Preventive Services Task Force (USPSTF). Data sources included relevant literature identified through searches of PubMed and EMBASE from 1966 to June 2012, and manual searches of the bibliographies of known primary and review articles. Outcome Measures: Studies must have been performed utilizing controlled local anesthetic blocks. Pain relief was categorized as at least 50% pain relief from baseline pain and the ability to perform previously painful movements. Results: A total of 25 diagnostic accuracy studies were included. Of these, one study evaluated 50% to 74% relief as criterion standard with a single block with prevalence of 48%, 4 studies evaluated 75% to 100% relief as the criterion standard with a single block with a prevalence of 31% to 61%, 5 studies evaluated 50% to 74% relief as the criterion standard with controlled blocks with a prevalence of 15% to 61%, and 13 studies evaluated 75% to 100% relief as the criterion standard with controlled blocks with a prevalence of 25% to 45% in heterogenous populations. False-positive rates ranged from 17% to 66% in the 50% to 74% pain relief group and 27% to 49% with at least 75% relief as the criterion standard. Based on this evaluation, the evidence showed that there is good evidence for diagnostic facet joint nerve blocks with 75% to 100% pain relief as the criterion standard with dual blocks and fair evidence with 50% to 74% pain relief as the criterion standard with controlled diagnostic blocks; however, the evidence is poor with single diagnostic blocks of 50% to 74%, and limited for 75% or more pain relief as the criterion standard. Limitations: The shortcomings of this systematic review of the accuracy of diagnostic lumbar facet joint nerve blocks include a paucity of literature and continued debate on an appropriate gold standard. Conclusion: There is good evidence for diagnostic facet joint nerve blocks with 75% to 100% pain relief as the criterion standard with dual blocks, with fair evidence with 50% to 74% pain relief. Key words: Chronic low back pain, lumbar facet or zygapophysial joint pain, facet joint nerve blocks, medial branch blocks, controlled comparative local anesthetic blocks
