Two Different Protocols for Knee Joint Motion Analyses in the Stance Phase of Gait: Correlation of the Rigid Marker Set and the Point Cluster Technique

Table 1

Pearson’s product moment correlation coefficients of landmarks estimated by RMS and the PCT.

	X	Y	Z
Great trochanter	0.92*	0.99*	0.95*
Lateral epicondyle	0.86*	0.99*	0.99*
Medial epicondyle	0.85*	0.99*	0.96*
Lateral condyle	0.87*	0.99*	0.99*
Medial condyle	0.75*	0.99*	0.93*
Lateral malleolus	0.87*	0.99*	0.99*
Medial malleolus	0.90*	0.99*	0.99*

^*Significant difference was 𝑃<0.01 for all landmarks.
