Table 4. Summary of inter-relationships for kinematic variables in factor three.

Column 1 Variables increasing / decreasing together	Column 2 Variables increasing / decreasing together & opposite to those in column 1
Thoracolumbar spine adduction (thorax up on R, pelvis down on R) @ toe-off	* Hip external transverse rotation @ heel-strike
Min thoracolumbar spine adduction (thorax up on R, pelvis down on R)	* Hip abduction @ impact
Thoracolumbar spine adduction (thorax up on R, pelvis down on R) @ heel-strike
Max thoracolumbar spine adduction (thorax up on R, pelvis down on R)
Thoracolumbar spine adduction (thorax up on R, pelvis down on R) @ impact

* Variables loading more strongly on other factors.
