View Full Version : Statistical analysis of joint moments

Hello everyone

I am planning a study to investigate the change in knee
moments over several repetitions of a step landing task with
3 different landing heights.

I am pretty sure that inter-individual variation may mask
subtle changes in knee loading across time, although a
number of papers that have compared this kind of measure,
such as peak moment and time to peak, across repeated trials
and different heights have used individual and group means
to conduct statistical analyses.

I am wondering if anyone is aware of a statistical approach
that may show a change in knee loading across repeated
trials and takes into account individual variation and
avoids fitting everyone onto the same curve which happens
with ensemble averaging.

Cluster analysis appears promising for this purpose, does
anyone have any thoughts????

Thanks for your help
