ABSTRACT

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.

    • "In all, we screened 2,879 publications and read the full text of 35 and finally identified 7 publications . While none of them targeted housing specifically, they pointed out significant sex differences in design requirements (Paquet and Feathers 2004; Kozey and Das 2004; Das and Kozey 1999); however, the current standards are not updated and do not support design adequately. It was concluded that since the standards do not reflect the body structure and functional capacity of the population with disabilities and the use of today's mobility devices, research-based revisions of current standards are required (Steinfeld et al. 2004, 2010; D'Souza et al. 2009; Ringaert et al. 2001).

    ABSTRACT: To increase the understanding of how definitions of standards for housing design influence the proportion of dwellings not meeting the standards and the proportion of individuals defined as having accessibility problems. The sample included old people and their dwellings in three European countries (N = 1,150). Frequencies and percentages were reported and empirical distribution functions were used. Depending on the functional profile and standards in question, the magnitude of influence of the standards differs in extent, e.g., the existing standard for door openings at the entrance (defined ≥75 cm) implied that the proportion of dwellings not meeting it was 11.3% compared to 64.4%, if the standard was set to ≥83 cm. The proportion of individuals defined as having accessibility problems for profiles not using mobility devices was 4-5, 57% for profiles using them and 1-3% for the total sample if the standard was set to 90 cm. Research-based standard definitions for housing design are necessary to ensure that they actually lead to enhanced accessibility, which is a prerequisite for the independence and health of persons with functional limitations.
