Musculoskeletal symptom survey among cement and concrete workers.

Work in construction is associated with a high risk for musculoskeletal disorders and injuries. The symptom survey was conducted to determine the magnitude and musculoskeletal injury characteristics among the cement and concrete workers and identify the most problematic work-related activities and job factors that might have contributed to the occurrence of these disorders. Findings revealed that a large proportion of the laborers (77%) experienced at least one musculoskeletal disorder in the last year. Low back pain was reported as the most frequently experienced symptom (66%). 'Working while in pain' the concrete workers perceived as the major problem in the trade. Other problematic work-related activities included 'bending or twisting the back', 'work in hot, cold or wet conditions', and 'handling heavy objects'. Most of the laborers (82%) requested on-the-job safety training. Survey results combined with the outcomes of focus groups discussions and work site observations were used in the design of a training program aimed at the prevention of musculoskeletal morbidity in the trade. The program incorporated ergonomics principles, hazard recognition, safe work practices, problem solving and personal protection in the training curriculum for membership of the trade.

Musculoskeletal symptom survey among mason tenders.

BACKGROUND: Low back pain (LBP) constitutes a major problem in construction. The magnitude and musculoskeletal injury characteristics in certain construction trades have been studied extensively. Musculoskeletal research targeting mason tenders is limited. High physical demands of the job primarily contribute to an increased risk of LBP experienced by these laborers. METHODS: A symptom survey was conducted to determine the magnitude and musculoskeletal injury characteristics among the mason tenders, and to identify work-related activities perceived by them as contributing to their disorders. RESULTS: The findings revealed that 82% of the mason tenders experienced at least one musculoskeletal symptom in the last year. LBP was the most frequently reported symptom (65%). Due to LBP, 12% of the laborers missed work and 18% of them visited a physician. Bending or twisting the back, working in the same position or in pain, and heavy lifting they perceived as the most problematic work-related activities. The vast majority of the laborers requested job-safety training. CONCLUSIONS: The mason tenders experienced high prevalence of LBP. To address the problem a model for primary prevention of LBP was developed and implemented in the trade. The model incorporated ergonomic principles, hazard recognition, and problem solving in the training curriculum for the union instructors teaching apprentices the trade-specific skills.

Enhancing the quality of life of a client with severe developmental disabilities through the application of assistive technology. A case study.

This paper describes a structural sequential process aimed to enhance the quality of life of a 29 year old man through the application of assistive technology (AT). The client had life-long severe multiple disabilities, showed increasing fragility and decreasing functional abilities that resulted, among other problems, in a problem with toileting. The process involved a thorough assessment and evaluation of the client, his physical, cognitive and perceptual skills involved in the performance of the task, requirements of the task, the technology, and the task environment. A clinical reasoning model for the provision of AT was applied during the process to identify the functional deficits of the client with respect to the problematic task. The approach enabled a multidisciplinary team of university-affiliated professionals including physical and occupational therapists, an ergonomist, a rehabilitation engineer and care providers in an institution for developmentally disabled people to determine the primary attributes of a technological intervention. The process resulted in the selection of an appropriate piece of AT followed by its modification and adaptation in order to address the specific needs of the client. The client's toilet use was improved in a manner that ultimately contributed to enhancing the quality of his life. Projections for further improvements of the quality of life of the client in this institution were also discussed.
