Pain profiles and psychosocial distress symptoms in workers with low back pain

Depression and anxiety in individuals with axial spondyloarthritis and nonspecific low back pain who are interested in non-pharmacological therapy options: Cross-sectional study

Psychological burden, such as depression and anxiety, may be associated with axial spondyloarthritis (axSpA) and poor prognosis of nonspecific low back pain (NSLBP). Non-pharmacological therapy is a substantial part of the management of both illnesses. Our study describes the psychological outcomes in patients with axSpA and NSLBP who were actively looking for non-pharmacological therapy. A total of 60 participants (34 with axSpA and 26 with NSLBP) were included in this cross-sectional study. Anxiety and depression were examined using the Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI-II), respectively. The relationships between BAI and BDI-II and quality of life (EQ-5D), pain intensity (NRS pain), disease activity (AS disease activity score, ASDAS-CRP), and function (Bath AS Functional Index, BASFI) were determined. The intensity of anxiety and depression did not differ between patients with and without axSpA. In both, axSpA and NSLBP, BAI, and BDI-II scores were inversely correlated with EQ-5D, R = -0.268 (P ˂ .05) and R = -0.486 (P ˂ .0001), respectively. We found a variation in the relationship between pain intensity and psychological outcomes in NSLBP and axSpA. The pain intensity score was correlated with the BDI-II (R = 0.542, P = .001) and BAI (R = 0.489, P = .003) scores only in patients with axSpA. In patients with axSpA, BAI was inversely correlated with disease duration (R = -0.356, P = .039) and positively correlated with increased disease activity and poor function, ASDAS-CRP (R = 0.431, P = .012) and BASFI (R = 0.621, P ˂ .0001) scores. The ASDAS-CRP score was positively correlated with BDI-II (R = 0.562, P = .001), and both disease activity and female sex were identified as risk factors for poor BDI-II outcomes in axSpA patients according to multiple regression analysis. Experiences of anxiety and depression seem to be similar for patients with axSpA and NSLBP in this selected group of participants. However, pain intensity may influence psychological outcomes, mainly in patients with axSpA. Disease activity, impaired function, and female sex were risk factors for anxiety and depression in patients with axSpA.

Clinical Guidance to Optimize Work Participation After Injury or Illness: The Role of Physical Therapists

Work rehabilitation refers to the process of assisting workers to remain at work or return to work (RTW) in a safe and productive manner, while limiting the negative impact of restricted work, unemployment, and work disability. The primary purpose of this clinical practice guideline (CPG) is to systematically review available scientific evidence and provide a set of evidence-based recommendations for effective physical therapy evaluation, treatment, and management of individuals experiencing limitations in the ability to participate in work following injury or illness.

Back pain among farmers in a northern area of China

STUDY DESIGN

This was a population-based survey conducted in 2008 in a northern area of China.

OBJECTIVE

To investigate back pain prevalence and to examine the associations between potential risk factors and back pain among Chinese farmers.

SUMMARY OF BACKGROUND DATA

Few studies have investigated back pain and its associated risk factors among farmers in low-income and developing nations.

METHODS

Farmers ages 15 years and older were chosen from 800 families in Heilongjiang province of the People's Republic of China using cluster sampling methods. Complete survey data were obtained from 2045 farmers. The prevalence of self-reported back pain during the previous 3 months was reported. Associations between back pain and potential risk factors, which included age, gender, education levels, perceived stress, main farm activities, smoking, and drinking status, were examined in logistic regression models.

RESULTS

A total of 786 (38.4%) farmers reported back pain. Two-thirds of those with back pain (66.0%) reported that back pain affected work quantity and quality. The adjusted odds ratios of reporting back pain increased with advancing age. Females and farmers who experienced stress regularly were also more likely to report back pain.

CONCLUSION

Back pain is a common problem among Chinese farmers and is reported more frequently by females. Significant positive associations of gender, age, and perceived stress with back pain warrant additional study.

On the effects of a workplace fitness program upon pain perception: a case study encompassing office workers in a Portuguese context

INTRODUCTION Office workers share several behavioural patterns: they work seated without moving for long times, they use only a few specific muscles of their arms, wrists and hands, and they keep an overall poor body posture. These working patterns generate musculoskeletal disorders, and produce discomfort or pain. Implementation of a work fitness program is thus a low-cost strategy to reduce/prevent body pain derived from work. The aim of this study was to test the benefits of a workplace fitness program, specifically applied to an administrative department of a Portuguese enterprise. Recall that this type of primary prevention level of musculoskeletal disorders has been seldom applied in Portugal, so this research effort materialized an important contribution to overcome such a gap. METHODS The participants in this study were office workers (n = 29 in the study group, and n = 21 in the control group)-who consistently had reported pain mostly on their back side (neck, posterior back, and dorsal and lumbar zones), wrists and posterior legs. The workplace fitness program consisted of three sessions per week during an 8-month period, with 15 min per session; emphasis was on stretching exercises for the body regions most affected by workers' pain perception. Each participant was requested to point out the injured region, as well as the intensity of pain felt, by using a visual analogue scale. Statistical analyses of the perceived pain data from control and study groups resort to non-parametric hypothesis tests. RESULTS There was a strong evidence that the workplace fitness program applied was effective in reducing workers' pain perception for their posterior back, dorsal and lumbar zones, and for their right wrist (P < 0.05). CONCLUSIONS These results generated are rather promising, so they may efficiently serve as an example for other enterprises in that country-while raising awareness on the important issue of quality of life at the workplace.
