Supervised Exercise Therapy Reduces Presenteeism to Greater Extent Than Unsupervised Self-Care in Workers with Musculoskeletal Pain: a Systematic Review and Meta-Analysis.

PURPOSE: Presenteeism is defined as the loss of work productivity due to health issues in workers, which can be measured subjectively. This study aimed to compare the effectiveness of supervised exercise therapy and unsupervised self-care in reducing presenteeism in workers with musculoskeletal disorders. METHODS: PubMed, Embase, and Cochrane Library were searched for various keywords from their inception to January 2023. Two examiners independently assessed the eligibility of studies: (1) studies involving workers suffering from musculoskeletal pain, (2) those involving supervised exercise therapy intervention with interactive communication, and (3) those in which the comparison group was subjected to interventions other than supervised exercise therapy, and (4) those including patient-reported outcome measures of presenteeism or work productivity or ability. Standardized mean differences (SMD) were calculated using a random effects model, with higher scores indicating reduced presenteeism in the intervention group compared with that in the comparison group. The GRADE assesses the overall certainty of the evidence. RESULTS: Only the short-term effects of interventions on presenteeism could be obtained using four studies. The intervention group showed statistically significant short-term effects on presenteeism compared with the comparison group (p < 0.001; SMD, 0.52; 95% confidence interval, 0.27-0.77). The GRADE score was downgraded by two levels from high to low due to concerns for indirectness. CONCLUSIONS: Although the certainty of the evidence was low, it was assumed that supervised exercise therapy was more effective than unsupervised self-care in reducing presenteeism in workers with musculoskeletal disorders.

Cross-cultural adaptation of the pain understanding and confidence questionnaire into Japanese.

[Purpose] This study aimed to develop a culturally adapted Japanese version of the Pain Understanding and Confidence Questionnaire (PUnCQ). The first-factor structure describes management from 12 perspectives for a case vignette of chronic pain and determines whether the management is based on a biomedical or biopsychosocial perspective. The second-factor structure evaluates the confidence level in management skills for the same case from 21 perspectives. [Participants and Methods] We conducted a cross-cultural adaptation based on five stages according to Beaton's guidelines (two forward translations, creation of an integrated forward translation version, two backward translations, creation of a provisional Japanese version, and a pilot test). In the pilot test, we asked 40 Japanese physical therapists to rate their understanding of the PUnCQ descriptions on a five-point Likert scale (1, not at all understandable; 5, completely understandable) and provide comments when they rated 1 to 3. We repeated revisions and pilot tests until less than 10% of the respondents rated 1 for all descriptions. [Results] By conducting two rounds of the pilot test, all items of descriptions satisfied the preestablished criteria. [Conclusion] A Japanese version of the PUnCQ was developed.
