Figure 3. — Marker placements from the front (a) and rear (b). Clouds of four and five markers were placed on the participant’s thigh and shank, respectively (highlighted in green). Clouds of four markers were placed on the thigh and shank components of the Myosuit (highlighted in orange). The choice of marker cloud sizes was driven by the initial sensitivity study where the chance of occlusion, marker loss, and marker stability were analysed. Additionally, markers were placed on the motor driving unit, left and right acromion, and the c7 vertebrae (highlighted in blue). (c) Angle convention for the shank and thigh segments in sagittal plane. The thigh angle (here ) is measured between the biological thigh and a vertical line passing through the knee joint’s centerline, with positive angles measured in the counter-clockwise direction. The shank angle (here ) is measured between the biological shank and the vertical line passing through the ankle joint’s centerline, with positive angles measured in the counter-clockwise direction. This angular convention was chosen as it matched the one used by the Myosuit controller.
