The purpose of this study was to evaluate the structural anthropometric dimensions of adult wheelchair users as part of a larger project that involved developing a database of the structural characteristics and functional abilities of wheelchair users. Measurements were made on 121 adult manual and powered wheelchair users with an electromechanical probe that registered the three-dimensional locations of 36 body and wheelchair landmarks. Thirty-one body and wheelchair dimensions (e.g., heights, breadths, depths) were calculated from the three-dimensional coordinate data. Tests of distributional normality showed that less than 1/3 of the dimensions were not normally distributed. ANOVA showed significant differences between powered and manual chair users, and women and men for only some of the anthropometric dimensions. The results of this study provide anthropometric information for a small and diverse group of wheelchair users using new measurement methods that may have value for three-dimensional human modeling and CAD applications.Relevance to industryAnthropometric data of wheelchair users can be applied toward the universal design of occupational environments and products that afford greater usability for wheelchair mobile user populations that are usually not considered in the design process.

    ABSTRACT: This study identified the factors existing in the methods and techniques used in the anthropometric analysis of wheelchair users which may adversely affect inter-population comparisons. Five studies of anthropometric analysis of wheelchair users were examined: Nowak (1996), Jarosz (1996), Das and Kozey (1999), Kozey and Das (2004) and Paquet and Feathers (2004). All the selected studies presented intra-and inter-population data. After having identified the methods and techniques cited, a comparison was made between the procedures used by these authors and those adopted by Barros (2007). The results indicate that inter-population comparison is valid only when there is similarity between the procedures and techniques used to collect data and the functional characteristics of the people evaluated.

    • "The paucity of anthropometric data on wheelchair users limits projects to creating environments and products that may be used effectively and safely, and this covers the concept of inclusive design [3] [4] [13]. There are no data, on a large scale, on the anthropometry of wheelchair users [12]. "

    ABSTRACT: This study deals with using digital photogrammetry to make an anthropometric analysis of wheelchair users. To analyse the data, Digita software was used, which was made available by means of the agreement of the Design Department of the Federal University of Pernambuco -Brazil -with the Department of Ergonomics of the Technical University of Lisbon -Portugal. Data collection involved a random sample of 18 subjects and occurred in the Biomechanics Laboratory of the Mau-rice of Nassau Faculty, located in Recife, Pernambuco. The methodology applied comprises the steps of Ergonomic Assess-ment, Configuration of the Data Base, Taking Digital Photographs, Digitalising the Coordinates and Presentation of Results. 15 structural variables related to static anthropometry were analysed, and 4 functional range variables relating to dynamic anth-ropometry. The results were presented by analysing personal data, classified by gender, ethnicity and age; by functional analy-sis of the sample, classified by clinical diagnosis, results of assessing the joints, results of the evaluation through motion and postural evaluation; and of the analysis of the anthropometric sample, which indicated for each variable the number of people, the mean, the standard deviation, and the minimum, median and maximum values.

Other studies that consider space requirements often concentrate on the advantages of specific (assistive) technologies and/or wheelchair type (Rogers, Berman, Fails, & Jaser, 2003; Steinfeld & Paquet, 2004), space requirements in terms of reach (Holliday, Mihailidis, Rolfson, & Fernie, 2005) or considered only simple straight path (Drury et al., 2008; Lin, Drury, & Paquet, 2006).

    ABSTRACT: Wheeled mobility device users face challenges in terms of access to the built environment and maneuverability within the built environment has received limited attention. As the wheeled mobility device user population has changed drastically in the recent years, there is a need to update accessibility standards and develop reliable methods for testing user performance in the built environment. This paper presents a comparison of restricted and unrestricted space requirements for angle turns (L-turns) with the aim of highlighting differences between space requirements in these situations and comparing the results to current accessibility standards. One hundred forty wheeled mobility device users completed L-turns to the best of their ability in a restricted space environment, and thirteen performed the same maneuver in an unrestricted space environment. Data indicates that although entrance dimensions of the turns are similar between the restricted space and unrestricted space groups, there is a significant difference between exit dimensions. This suggests that when unrestricted space is utilized, users may adopt different strategies and paths when executing their turns. Additionally, a comparison of the study results, both in the restricted and unrestricted conditions, to current accessibility standards indicates that a large proportion of individuals may not be able to successfully complete L-turns in compliant built environments. In the design of the built environment, researchers and designers should consider space requirements, ease of execution and time of execution simultaneously to create comfortable and accessible environments for normal and urgent circumstances.
