The purpose of this study was to quantitatively analyze the stress and deformation that occur in plastic ankle-foot orthoses (PAFOs) during walking after it is trimmed. First, PAFOs with incorporated sensors were individually prepared for 2 patients with hemiplegia. Mechanical data were then obtained while individuals wore the PAFOs during walking. Here we report the results of mechanical data and finite element analysis of trimmed plastic ankle-foot orthoses worn by two patients with left-hemiplegia. The results could provide prosthetists with some suggestions for forming orthoses.

The aim of the study is to examine the effect of the amount of the dissolved gas on the two phase flow and to examine the acceleration of bubble generation on two-phase nozzle flow by modifying the shape of orifice plate. In the experiment, the molar concentration of CO2 gas was changed at the dissolution process. As increasing the CO2 molar concentration, the void fraction increased and the liquid velocity decreased at the throat. On the other hand, the bubble velocity was almost constant when dissolved gas rate was changed. Therefore, the slip velocity between the bubble and the liquid increased. Moreover, the amount of bubble is different by changing the hole type of orifice plate such as different holes diameter and respective cross section area for each plate. In case of the orifice of seven holes, it cannot reach the sound speed at the throat but it is closest to the sound speed in the case of other orifices.
