Figure 4From: A two-axis cable-driven ankle-foot mechanismStrain gauge placement in the foot. (A) For the sagittal plane torque, two strain gauges are used for push-off torque estimation (SDP1) and two strain gauges are used for heel-strike torque estimation (SDP2). (B) For the frontal plane torque, two strain gauges are used for push-off torque estimation (SIE1).Back to article page
