  • Summary:mean distance/ range of distances between the ischialtuberosities

    Below a summary of responses to the question I posted a few weeks ago
    on mean distance/ range of distances between the ischial tuberosities. I
    would like to thank all of you who responded. Following the question I asked
    with the replies

    Dear all,

    does anyone know if there is some information available regarding the mean
    distance/ range of distances between the ischial tuberosities
    in a seated position? Ideally I am looking for some anthropometric
    tables of the German/European population.
    I would be very appreciative if any of you could give me
    advice, suggestions or references regarding this problem
    Thank you for your time and consideration in advance

    I can not think of any such specialized information document at this time,
    but I bet there are more than one that deal with the sitting
    pressures. However, I think that most of the technical articles I have
    on the subject have a grand sample size of one! They are only
    feasibility studies.

    In the meantime, I suggest that you use an estimate for the mean of .25
    times the Bitrochanteric Breadth (Hip Breadth, standing) for the
    populations you have in mind. The standard deviation would probably be
    close to .25 times that of the standard deviation for the Bitrochanteric
    Breadth, though perhaps less because of the absence of fatty tissue in
    the bones.

    Try PeopleSize Software (http://www.openerg.com)
    It gives the distance between inner edges of the ischial tuberosities
    and their width.

    There is some anthro data on ITs in the new publications by the UK
    Department of Trade and Industry. Contact Paul Hale at
    paul.hale@dti.gov.uk. Data for several different populations are available.

    Hi,
    You can try the book titled "Bodyspace-- Anthropometry, Ergonomics and
    Design", Author: Stephen Pheasant, published by Taylor & Francis, 1986,
    Reprinted 1988, 1990, 1992, 1994.

    I don't know whether you have your answer yet, but in 'Adultdata', which is
    produced by the Department of Trade and Industry here in the UK, I found:

    UK, male, mean (SD) 117.9 (11.3), 5th / 95th %tile: 99.4 / 136.5, female
    129.4 (10.1) 112.7 / 146.1
    USA, male 118.3 (11.4) 99.5 / 137.1, female 129.9 (11.1) 111.7 /
    148.1
    The booke quotes as its source "PeopleSize 1998", which is a
    computerdatabase.
    More info on that at http://www.openerg.com

    Hope this helps,
