analysis methods on running gait analysis. Markers placed on the shoe heel counter were
compared with markers placed directly on the calcaneous and visible through heel
windows cut into the shoe. When analyzed using a traditional group design no
significant differences were found between marker conditions for rear foot eversion
excursion, percent stance at which peak eversion occurred, maximal instantaneous
eversion velocity, or maximal instantaneous vertical loading rate. Ankle frontal plane
variability was significantly different between conditions. When analyzed with a single
subject design some individuals demonstrated significant differences between conditions
while others did not. In some individuals the heel windows condition revealed previously
masked coupling parameters thought to be related to injury. The results of this study
suggest the heel windows method and single subject analysis should be used for a
longitudinal study of runners. === Committee in Charge:
