From: Using an electrohydraulic ankle foot orthosis to study modifications in feedforward control during locomotor adaptation to force fields applied in stance

Figure 2

Effects of force field 20% on joint kinematics. a. Torque applied on a subject's ankle (S3) by the EHO during mid-stance. Baseline (grey band) and force field late (thick black line). Outside of the force field application zone, the EHO applied a null field to minimize its influence on the subject's walking pattern. b. Knee angular displacements superimposed for baseline (grey band), force field early (thin black line), force field late (thick black line), and last catch (dashed line). c. Ankle angular displacements superimposed for baseline (grey band), force field early (thin black line), force field late (thick black line), and last catch (dashed line). d. Ankle angular velocity for the same traces as in 'c'. Grey box: zone used for velocity measurement. Grey bands represent mean value ± 2 STD. For all conditions, data were synchronized on heel strike. Abbrev. WA: weight acceptance; MS: mid-stance; PO: push-off; DF: dorsiflexion; PF: plantar flexion; HS: heel strike.
