Greetings:
Clinical gait analyses often present the 3D orientation of the hip, knee
and ankle joints, throughout a gait cycle, as lines superimposed on
'normative' data plots. Within the literature, and available on the WWW
are many examples of such plots (i.e. visit
http://guardian.curtin.edu.au/cga/data/kinematics.jpg ).
However, locating quantitative data to reproduce 'normative' plots are
difficult to find likely because they are motion system manufacture
property or results from a specific lab {I myself have a small database
based on 10 individuals selected with a wide range of height and mass
which was used to test the ability of various gait data scaling
approaches to minimize inter-subject gait variation. see Pierrynowski
and Galea, Gait and Posture 13 (2001) 193-201}.
However, at present, I am working on a project that requires knowing the
following 18 (3x3x2) values:
Averaged over a typical gait cycle (I do not need within gait cycle
values or non-standard walking speeds) the
(3) hip, knee and ankle,
(3) 3D orientation kinematics (flexion-extension, abduction-adduction,
internal-external rotation),
(2) within and between subject
dispersions (sample standard deviation preferred).
In addition, the characteristics of the subjects the data was obtained
from would be helpful (i.e. number of gait cycles, age range, height, mass
If anyone with the BIOMCH-L community can direct me towards such data,
or can provide me with same, I would be most appreciative.
As usual, I will post a summary of my findings.
Thanks in advance,
