We are collecting temporal and spatial measures of gait from elderly
people, some of whom are hemiparetic.
I am searching for an index of symmetry to apply to these parameters.

I recall seeing an argument recently that such an index should be based
upon differences between right and left side values, rather than upon a
ratio of the two. This made sense, but unfortunately I cannot now find the
paper in which I read this.

There are a few references in the archives, which I am follwing up, but I
would appreciate any further thoughts on this matter.
I will post a summary of any replies.
Many Thanks
