Relationship between occupational injury and gig work experience in Japanese workers during the COVID-19 pandemic: a cross-sectional internet survey. INDUSTRIAL HEALTH 2022; 60:360-370.

Abstract
This study evaluated the relationship between occupational injury risk and gig work, which included the exchange of labor for money between individuals or companies via digital platforms. As Japan has experienced a severe economic decline during the coronavirus disease 2019 (COVID-19) pandemic, an increasing number of individuals have engaged in gig work. While few studies have evaluated occupational risks in gig work, several traffic accidents associated with food delivery gig work have been reported in the mass media. In this study, 18,317 individuals completed an internet survey that collected information pertaining to their involvement in gig work and experience of related occupational injuries; data regarding several confounding factors were also recorded. Multiple logistic regression analysis showed that workers involved in gig work had a greater risk of any minor occupational injuries (odds ratio, 3.68; 95% confidence interval, 3.02-4.49) and activity-limiting injuries (odds ratio, 9.11; 95% confidence interval, 7.03-11.8) than those not involved in gig work, after adjusting for age, sex, household income, lifestyle factors, and work-related factors. The results of this study indicate that gig workers are exposed to greater occupational hazards during the COVID-19 pandemic. Additional studies are warranted to clarify the causal mechanism for this relationship.

The effectiveness of structured patient education for the management of musculoskeletal disorders and injuries of the extremities: a systematic review by the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration.

Abstract
PURPOSE To determine the effectiveness of structured patient education for the management of musculoskeletal disorders and injuries of the extremities. METHODS We searched MEDLINE, EMBASE, CINAHL, PsycINFO, and the Cochrane Central Register of Controlled Trials from January 1, 1990 to March 14, 2015. Paired reviewers independently screened titles and abstracts for eligibility. The internal validity of studies was assessed using the Scottish Intercollegiate Guidelines Network (SIGN) criteria. Results from studies with a low risk of bias were synthesized using the best-evidence synthesis methodology. RESULTS We identified two randomized trials with a low risk of bias. Our review suggests that: 1) multimodal care and corticosteroid injections lead to faster pain relief and improvement than reassurance and advice in the short-term and similar outcomes in the long-term for patients with persistent lateral epicondylitis; and 2) providing health education material alone may be less effective than multimodal care for the management of persistent patellofemoral pain syndrome. CONCLUSION Our systematic search of the literature demonstrates that little is known about the effectiveness of structured patient education for the management of musculoskeletal disorders and injuries of the extremities. Two studies suggest that when used alone, structured patient education may be less effective than other interventions used to manage persistent lateral epicondylitis and persistent patellofemoral syndrome.

The effectiveness of soft-tissue therapy for the management of musculoskeletal disorders and injuries of the upper and lower extremities: A systematic review by the Ontario Protocol for Traffic Injury management (OPTIMa) collaboration. ACTA ACUST UNITED AC 2015; 21:18-34. [PMID: 26386912 DOI: 10.1016/j.math.2015.08.011] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2014] [Revised: 04/29/2015] [Accepted: 08/21/2015] [Indexed: 12/26/2022]
Abstract
BACKGROUND Soft-tissue therapy is commonly used to manage musculoskeletal injuries. OBJECTIVE To determine the effectiveness of soft-tissue therapy for the management of musculoskeletal disorders and injuries of the upper and lower extremities. DESIGN Systematic Review. METHODS We searched six databases from 1990 to 2015 and critically appraised eligible articles using Scottish Intercollegiate Guidelines Network (SIGN) criteria. Evidence from studies with low risk of bias was synthesized using best-evidence synthesis methodology. RESULTS We screened 9869 articles and critically appraised seven; six had low risk of bias. Localized relaxation massage provides added benefits to multimodal care immediately post-intervention for carpal tunnel syndrome. Movement re-education (contraction/passive stretching) provides better long-term benefit than one corticosteroid injection for lateral epicondylitis. Myofascial release improves outcomes compared to sham ultrasound for lateral epicondylitis. Diacutaneous fibrolysis (DF) or sham DF leads to similar outcomes in pain intensity for subacromial impingement syndrome. Trigger point therapy may provide limited or no additional benefit when combined with self-stretching for plantar fasciitis; however, myofascial release to the gastrocnemius, soleus and plantar fascia is effective. CONCLUSION Our review clarifies the role of soft-tissue therapy for the management of upper and lower extremity musculoskeletal disorders and injuries. Myofascial release therapy was effective for treating lateral epicondylitis and plantar fasciitis. Movement re-education was also effective for managing lateral epicondylitis. Localized relaxation massage combined with multimodal care may provide short-term benefit for treating carpal tunnel syndrome. More high quality research is needed to study the appropriateness and comparative effectiveness of this widely utilized form of treatment.
