Table 2.

The table shows Mean ± Std.

ERROR IN ANGLE
Right—hip flexion/extension (degrees)	1.02 ± 0.006
Left—hip flexion/extension (degrees)	0.81 ± 0.006
Right—knee flexion/extension (degrees)	0.91 ± 0.011
Left—knee flexion/extension (degrees)	1.021 ± 0.011
Left—hip abduction/adduction (degrees)	0.55 ± 0.003
ERROR IN POSITION
Right—X position (cm)	0.68 ± 0.005
Left—X position (cm)	0.54 ± 0.004
Right—Y position (cm)	0.10 ± 0.0008
Left—Y position (cm)	0.13 ± 0.001
Left—Z position (cm)	0.23 ± 0.002
Time delay (s)	0.008 ± 0.0002

Error of the (a) difference between actual and desired position (error in position) in the left and right foot in X and Y direction and in the left foot in Z direction, (b) difference between actual and desired hip and knee angle in sagittal plane for right and left leg and hip angle in coronal plane for left leg (error in angle), and (c) time delay (time for each iteration of the loop) to reach the actual position based on user input force.
