Abstract
For the purpose of understanding the characteristics of activity of daily living (ADL) among the hemophilia patients, an anonymous survey was conducted. Main items investigated were subjects' biographical data, such as age, impairment level, pain, bleeding history, and level of ADL accomplishment. The difficulty degree of 21 items of ADL was investigated and a ranking analysis was performed by using quantification theory type III. Valid responses were 259 (37.5%), average age was 40.9 years old, and joints with much sharp pain and bleeding were elbow, knee, and ankle. The most difficult ADL were sitting straight, running, and using Japanese-style toilet. According to the result of quantification theory type III, the 1st. axis was interpreted as ability for ADL. It was able to be said so because the ratio for all axial variance was 42%, and ADL of the subjects could almost be interpreted on the 1st. axis. According to the scatter plot of the category score, 21 items of ADL were categorized into two clusters. Cluster 1: Flexion and load of lower limbs. Cluster 2: Composite movement of upper and lower extremities. The range was calculated from category score between 2 groups' degree of difficulty of 21 items of ADL. As a result, the movement most influenced by the ADL score were sitting straight and using Western-style toilet, and the movement least influenced by the ADL score were attaching and removing buttons and cutting toe nails.
