TABLE 4.

Spearman’s rank correlation coefficient values between the index values calculated by the gait analysis system in the Welwalk WW-2000 and the marker-based motion capture system.

Abnormal gait patterns	Spearman’s rho
Hip hiking	0.83 (0.69–0.92)
Circumduction	0.93 (0.80–0.95)
Retropulsion of the hip	0.92 (0.79–0.96)
Excessive hip external rotation	0.89 (0.76–0.93)
Excessive lateral shift of the trunk over the unaffected side	0.88 (0.70–0.93)
Knee extensor thrust	0.91 (0.61–0.95)
Medial whip	0.86 (0.76–0.96)
Trunk posterior tilt	0.68 (0.59–0.86)
Contralateral vaulting	0.71 (0.22–0.85)

Data are presented as median (from minimum to maximum) of the Spearman’s rank correlation coefficient values of all participants.
