View Full Version : How many normals in your 3DGA database?

Dear Biomech-L,

I have searched through the Biomech-L archives to find there is
agreement that each gait analysis laboratory should develop its own set
of 'normals' according to their own protocols etc.

The information I cannot find is any consensus on how many are required
for your 'normals' database to be acceptable.

Could I take a quick survey of:
How many 'normals' you have in your laboratory database (in age/other
categories as appropriate)?
Does the chosen number have statistical or other justification?
Is the number in your database purely chosen by available resources for
data collection?
