Design outcomes

Primary

Measure	Time frame
The joint angle of the lower limbs during the landing motion is evaluated using a three-dimensional motion analysis device (VICON 612, Oxford). Measurement is carried out until three successive trials are recorded, and the average value of three times is used as a representative value of the research subject for analysis. [Setting rationale] In this study, in order to study the influence of the use of ankle orthosis on knee joint movement, it is necessary to calculate the joint angle of the lower limb and use it for analysis	—

Secondary

Measure	Time frame
The ground reaction force By evaluating the floor reaction force component, we analyze the impact applied to the joint. The average value of the three measured data is used as a representative value for analysis. [Setting rationale] The floor reaction force component reflects the strength of energy generated at the time of landing, the three-dimensional direction in which the energy works, and the temporal element, thereby analyzing the floor reaction force component, whereby the trauma other than the joint angle. Because it is possible to consider the risk of disability.	—
