Inverted Pendulum Standing Apparatus for Investigating Closed-Loop Control of Ankle Joint Muscle Contractions during Functional Electrical Stimulation

Table 2

The average standard deviation values of the pendulum angle and torque fluctuations for the PDstimLD and NOstim conditions for each subject. Each value represents the mean ± one standard deviation for three trials in each condition.

Subject	Angle standard deviation deg		Torque standard deviation Nm
	PDstimLD	NOstim	PDstimLD	NOstim
A	0.504 ± 0.222	0.382 ± 0.121	1.38 ± 0.55	0.96 ± 0.23
B	0.565 ± 0.194	0.621 ± 0.510	1.41 ± 0.48	1.64 ± 1.21
C	1.486 ± 0.411	0.418 ± 0.126	3.55 ± 1.09	1.05 ± 0.29
