Importance of being collaborative for return to work with back pain

Comparison of diclofenac with tramadol, tizanidine or placebo in the treatment of acute low back pain and sciatica: multi-center randomized controlled trial

BACKGROUND

Low back pain (LBP) is a leading cause of disability worldwide and has posed numerous health and socioeconomic challenges. This study compared whether nonsteroidal anti-inflammatory drugs (NSAIDs) in combination with tramadol, tizanidine or placebo would be the best treatment regime to improve the Roland Morris Disability Questionnaire (RMDQ) scores at 1 week.

METHODS

This was a multi-center, double-blind, randomized, and placebo-controlled trial including adult patients with acute LBP and sciatica in three emergency departments in Hong Kong. Patients were randomized to the receive tramadol 50 mg, tizanidine 2 mg, or placebo every 6 hours for 2 weeks in a 1:1:1 ratio. The RMDQ and other secondary outcomes were measured at baseline, Day 2, 7, 14, 21, and 28. Data were analyzed on an intention to treat basis. Crude and adjusted mean differences in the changes of RMDQ and NRS scores from baseline to Day 7 between tizanidine/tramadol and placebo were determined with 95% confidence intervals.

RESULTS

Two hundred and ninety-one patients were analyzed with the mean age of 47.4 years and 57.7% were male. The primary outcome of mean difference in RMDQs on Day 7 (compared with baseline) was non-significant for tizanidine compared with placebo (adjusted mean difference - 0.56, 95% CI -2.48 to 1.37) and tramadol compared with placebo (adjusted mean difference - 0.85, 95% CI -2.80 to 1.10). Only 23.7% were fully compliant to the treatment allocated. Complier Average Causal Effect analysis also showed no difference in the primary outcome for the tizanidine and tramadol versus placebo.

CONCLUSION

Among patients with acute LBP and sciatica presenting to the ED, adding tramadol or tizanidine to diclofenac did not improve functional recovery.

A logic model for a self-management program designed to help workers with persistent and disabling low back pain stay at work

BACKGROUND

Workers with persistent disabling low back pain (LBP) often encounter difficulty staying at work. Self-management (SM) programs can offer interesting avenues to help workers stay at work.

OBJECTIVE

To establish the plausibility of a logic model operationalizing a SM program designed to help workers with persistent disabling LBP stay at work.

METHODS

We used a qualitative design. A preliminary version of the logic model was developed based on the literature and McLaughlin et al.'s framework for logic models. Clinicians in work rehabilitation completed an online survey on the plausibility of the logic model and proposed modifications, which were discussed in a focus group. Thematic analyses were performed.

RESULTS

Participants (n = 11) found the model plausible, contingent upon a few modifications. They raised the importance of making more explicit the margin of maneuver or "job leeway" for a worker who is trying to stay at work and suggested emphasizing a capability approach. Enhancing the workers' perceived self-efficacy and communication skills were deemed essential tasks of the model.

CONCLUSION

A plausible logic model for a SM program designed for workers with disabling LBP stay at work was developed. The next step will be to assess its acceptability with potential users.

Education as a strategy for managing occupational-related musculoskeletal pain: a scoping review

BACKGROUND

Musculoskeletal (MSK) pain is the primary contributor to disability worldwide. There is a growing consensus that MSK pain is a recurrent multifactorial condition underpinned by health and lifestyle factors. Studies suggest that education on work-related pain and individualised advice could be essential and effective for managing persistent MSK pain.

OBJECTIVE

The objective of this scoping review was to map the existing educational resources for work-related MSK (WRMSK) pain, and the effects of implementing educational strategies in the workplace on managing WRMSK pain.

METHODS

This scoping review assessed original studies that implemented and assessed education as a strategy to manage WMSK pain. Literature search strategies were developed using thesaurus headings (ie, MeSH and CINAHL headings) and free-text search including words related to MSK in an occupational setting. The search was carried out in PubMed, CINAHL, Cochrane Library and Web of Science in the period 12-14 February 2019.

RESULTS

A total of 19 peer-reviewed articles were included and the study design, aim and outcomes were summarised. Of the 19 peer-reviewed articles, 10 randomised controlled trial (RCT) studies assessed the influence of education on work-related MSK pain. Many studies provided a limited description of the education material and assessed/used different methods of delivery. A majority of studies concluded education positively influences work-related MSK pain. Further, some studies reported additive effects of physical activity or ergonomic adjustments.

CONCLUSIONS

There is a gap in knowledge regarding the best content and delivery of education of material in the workplace. Although beneficial outcomes were reported, more RCT studies are required to determine the effects of education material as compared with other interventions, such as exercise or behavioural therapy.
