Correlation of biofeedback and subject's activity

Joint	Hip right		Knee right		Hip left		Knee left
Gait phase	Stance	Swing	Stance	Swing	Stance	Swing	Stance	Swing
Subject P1	-0.17	0.71	0.18	0.80	-0.17	0.71	0.19	0.80
Subject P2	0.31	0.82	-0.14	0.63	0.22	0.79	-0.29	0.72
Subject P3	0.68	0.79	-0.75	0.74	0.50	0.77	-0.69	0.72

Spearman correlation coefficients of the obtained biofeedback values and the level of activity with which they were instructed to walk in the DGO (0 = passive, 1 = active, 2 = exaggerated). In three individuals, correlations are show independently for the four actuated joints and for stance and swing phase.
