A digital watermarking scheme permits embedding additional information into digital contents as a watermark so that the embedded information can be detected afterward. In detecting a watermark, there are two kinds of detection errors, a false positive error (FPE) and a false negative error (FNE). A detection scheme is said to be optimum if the FNE(More)
[Purpose] The trunk muscles frequently become weak after stroke, thus impacting overall activities of daily living. However, activities of daily living items closely related with trunk strength remain unclear. This study aimed to clarify the influence of trunk muscle weakness on activities of daily living items. [Subjects] The subjects were 24 stroke(More)
[Purpose] The aim of the present study was to elucidate which motor functions are most or more important for dressing performance before and after rehabilitation. [Subjects] Seventy-nine first episode stroke patients in a hospital convalescent rehabilitation ward. [Methods] The relationships between motor function of the affected upper and lower limbs,(More)
OBJECTIVE This study established motor function cutoff values for dressing independence in inpatients with stroke. METHODS Ninety-eight first-time inpatients with stroke were divided into groups on the basis of independence level in dressing, and receiver operating characteristic curves were determined for balance, motor function of affected limbs, trunk(More)
[Purpose] This study aimed to clarify the independent impact of the affected upper and lower limb, trunk, and unaffected side motor functions on activities of daily living in stroke patients using partial correlation analysis. [Subjects and Methods] This retrospective study included 77 stroke patients. Motor functions were assessed using the Stroke(More)
[Purpose] Interventions using music, physical exercise, and reminiscence therapy are widely used both for rehabilitation and care of the elderly. This study aimed to investigate the effect of structured interventions comprising music, physical exercise, and reminiscence therapy on cognitive function and quality of life of the community-dwelling elderly.(More)
[Purpose] Dressing is an activity of daily living for which stroke patients often show discrepancies between capacity and actual performance. The aim of this study was to elucidate the physical function and unilateral spatial neglect in stroke patients that reduce their level of actual performance despite having the capacity for dressing independently.(More)
BACKGROUND This study aimed to create a simple and objective indicator for use by inexperienced nurses and family members of patients to judge the assistance level required for dressing in a hospital, while encouraging independence in activities of daily living among inpatients with stroke using the Berg balance scale. METHODS We retrospectively analyzed(More)
PURPOSE The purpose of this study was to clarify the amount of balance necessary for the independence of transfer and stair-climbing in stroke patients. METHOD This study included 111 stroke inpatients. Simple and multiple regression analyses were conducted to establish the association between the FIM® instrument scores for transfer or stair-climbing and(More)
