Does ergonomic mismatch at school impact pain in school children?

Musculoskeletal pain in school-aged children is highly prevalent. While there are many potential factors relating to this discomfort, one unexplored factor is the ergonomic mismatch. The objective of this study was to determine whether the degree of mismatch between the body dimensions and the classroom furniture was associated with body discomfort. One hundred and thirty-nine children in a Midwestern U.S. school district participated in the study where demographic information, anthropometric measurements, self-reported regional body discomfort, and furniture measurements were collected. The results indicate an extremely high prevalence of ergonomic mismatch. Contrary to what was hypothesized, the ergonomic mismatch was not associated with body discomfort. The lack of association may have been a result of the extremely high prevalence of ergonomic mismatch as well as potential adaptations by the students. Although almost every student was found to not fit their desk and chairs, ergonomic mismatch had limited impact on the body discomfort. It appears that other factors such as backpack weight and time carrying may contribute more to the discomfort of students. However, caution is stress with regard to dismissing ergonomic mismatch factor as a potential risk factor since the extremely high prevalence may have washed out any effect.

Can a transitional work grant program in a workers' compensation system reduce cost and facilitate return to work?

Although previous research has shown returning the injured worker to work as soon as possible is important to the long-term prospects of the worker remaining in the work force, there is limited economic support for implementing such programs. Thus, the purpose of this case control study was to determine the cost savings of the implementation of a Transitional Work Grant (TWG) program, which consisted of several components including job analyses, education, communication and transitional work (TW). Companies that enrolled in the TWG program were matched to nonparticipating companies (NTW) based on employer size, type of industry, number of overall claims, and number of claims with > 7 days lost time (LT claims) submitted the year prior to enrollment. The study analyzed economic data: number of claims, number of LT claims, indemnity costs, medical costs, and days lost (days away from the workplace). An additional outcome was the ratio of LT claims (> 7 days lost work) to medical only (MO) claims (LT/MO ratio). Overall, participation in the TWG program was associated with decreased indemnity cost and decreased LT/MO ratio. However, effectiveness of the program varied by employer size and industry. In terms of the state of Ohio, these costs translate into substantial savings: more than $2.3 million per year. Although the cost savings and reduction in lost time claims is encouraging, the true benefit of TW has yet to be completely quantified. Future work must account for other potential co-factors and programs that could also contribute to the savings as well as document further the indirect benefits associated with a TWG program, such as improved employee morale and increased productivity and product quality that could be four times greater than the direct savings. In summary, programs such as this one adopted by several companies in Ohio can reduce the cost burden of injuries.
