Wheatstone bridges. (A) Strain gauge placement in the Wheatstone bridge for the sagittal plane torque estimation. Two strain gauges are used for push-off torque estimation in the sagittal plane (S_DP1), and two strain gauges are used for heel-strike torque estimation in the sagittal plane (S_DP2). (B) Strain gauge placement in the Wheatstone bridge for the frontal plane torque estimation. Two strain gauges are used for push-off the frontal plane torque estimation (S_IE).
