      This study aimed to identify aspects that may significantly influence the satisfaction of Ankle-Foot Orthosis (AFO) users and those who have discontinued AFO use. Interviews were conducted with AFO users and former users, and the interview content was analyzed using Steps for Coding and Theorization(SCAT). The resulting theoretical descriptions were categorized and interpreted. As a result, it became evident what AFO users expect to achieve by wearing AFOs, areas where improvements in AFO structure are desired, and the needs related to AFO provision services. Based on the findings of this study, it is expected that improvements can lead to the delivery of better AFOs and services to the users.

      Fatigue reduces mental activity during the day and may induce mood swings, errors due to inattention, poor performance in overall behavior, and accidents due to falling asleep. In fatigue measurement, there is a need for a method that can measure fatigue immediately and easily each time it occurs. We have studied the detection of fatigue states from speech using chaos theory, but have been unable to determine the actual degree of fatigue or the degree of focus on the task. In this study, salivary amylase was measured as an objective index of fatigue, and LF/HF was measured from heart rate variability during the fatigue task, which was examined together with the results of voice analysis. As a result, the participants in the experiment objectively responded in a way that meant they were fatigued, and it was possible to infer this state from their speech.
