From: Effects of a powered ankle-foot orthosis on perturbed standing balance
Normalized total ankle torque and normalized biological ankle torque. a Torques in response to a small perturbation, mean over all subjects. b Torques in response to a large perturbation, mean over all subjects. c Mean of the RMS of the normalized torques computed over the small perturbations for each subject individually. d Mean of the RMS of the normalized torques computed over the large perturbations for each subject individually. The grey boxes indicate the perturbation period
