Background: Scaffold erectors are at risk of high exposure to the aforementioned hazards associated with the dynamic human-scaffolding interface and work environments. Identifying an optimal work strategy can help reduce risk of injuries to the worker. Method: Three carrying methods, four types of work surfaces, two weights of scaffold frames, and three directions of stepping movement were tested in a laboratory with 18 construction workers. Results: The effects of carrying method on postural instability and task difficulty rating were significant for handling the 22-kg end frame. Response time, postural instability, and perceived task difficulty rating were significantly reduced when the 9-kg end frame was used as compared with the 22-kg frame. Conclusion: The symmetric side-carrying method was the best option for handling 22-kg scaffold end frames. A 9-kg end frame (e.g., made of reinforced lightweight materials) has the potential to reduce injury risk among scaffold handlers during their scaffold erection and dismantling jobs. Application: Scaffold erectors may want to adopt the symmetric side-carrying method as the primary technique for handling the 22-kg scaffold end frame, which is currently the one most used in the industry. <\/jats:p>","DOI":"10.1518\/001872008x250548","type":"journal-article","created":{"date-parts":[[2008,2,12]],"date-time":"2008-02-12T00:57:37Z","timestamp":1202777857000},"page":"27-36","source":"Crossref","is-referenced-by-count":2,"title":["Effect of Scaffold End Frame Carrying Strategies on Worker Stepping Response, Postural Stability, and Perceived Task Difficulty"],"prefix":"10.1177","volume":"50","author":[{"given":"Hongwei","family":"Hsiao","sequence":"first","affiliation":[{"name":"National Institute for Occupational Safety and Health, Morgantown, West Virginia,"}]},{"given":"Mathew","family":"Hause","sequence":"additional","affiliation":[{"name":"National Institute for Occupational Safety and Health, Morgantown, West Virginia"}]},{"suffix":"Jr","given":"John R.","family":"Powers","sequence":"additional","affiliation":[{"name":"National Institute for Occupational Safety and Health, Morgantown, West Virginia"}]},{"given":"Tsui-Ying","family":"Kau","sequence":"additional","affiliation":[{"name":"National Institute for Occupational Safety and Health, Morgantown, West Virginia"}]},{"given":"Scott","family":"Hendricks","sequence":"additional","affiliation":[{"name":"National Institute for Occupational Safety and Health, Morgantown, West Virginia"}]},{"given":"Peter I.","family":"Simeonov","sequence":"additional","affiliation":[{"name":"National Institute for Occupational Safety and Health, Morgantown, West Virginia"}]}],"member":"179","published-online":{"date-parts":[[2008,2,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"crossref","first-page":"83","DOI":"10.3233\/OER-2003-3201","volume":"3","author":"Bhattacharya, A.","year":"2002","journal-title":"Occupational Ergonomics"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.3109\/00016488009127171"},{"volume-title":"Table R12: Number of nonfatal occupational injuries and illnesses involving days away from work by occupation and selected events or exposures leading to injury or illness, 2001","year":"2004","author":"Bureau of Labor Statistics.","key":"atypb3"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-6870(00)00016-8"},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1080\/00140138308963312"},{"key":"atypb6","doi-asserted-by":"publisher","DOI":"10.1080\/00140136308930715"},{"key":"atypb7","doi-asserted-by":"publisher","DOI":"10.1093\/ageing\/11.1.11"},{"key":"atypb8","doi-asserted-by":"publisher","DOI":"10.1080\/001401399184712"},{"key":"atypb9","doi-asserted-by":"publisher","DOI":"10.1016\/0966-6362(95)01030-0"},{"key":"atypb10","doi-asserted-by":"publisher","DOI":"10.1080\/00140139108967324"},{"key":"atypb11","doi-asserted-by":"publisher","DOI":"10.1016\/S0169-8141(96)00023-6"},{"key":"atypb12","doi-asserted-by":"publisher","DOI":"10.1080\/00140130500197112"},{"key":"atypb13","doi-asserted-by":"publisher","DOI":"10.1016\/0169-8141(95)00103-4"},{"key":"atypb14","unstructured":"Hsiao, H. & Stanevich, R.
