BACKGROUND In an adaptive clinical trial (ACT), key trial characteristics may be altered during the course of the trial according to predefined rules in response to information that accumulates within the trial itself. In addition to having distinguishing scientific features, adaptive trials also may involve ethical considerations that differ from more traditional randomized trials. Better unde...

BACKGROUND Although exposure to second-hand smoke (SHS) has been associated with various medical conditions, only limited data are available on its association with health-related quality of life (HRQOL), particularly data obtained with the EQ-5D or EQ visual analogue scale (VAS). METHODS This cross-sectional study evaluated 10,532 adult never-smokers who participated in the fifth Korea Natio...

OBJECTIVES To evaluate the clinical pain during local anesthetic injection using such intra-oral device. STUDY DESIGN A comparative split-mouth clinical study to evaluate clinical pain was conducted among the subjects who required bilateral local anesthetic intra-oral injections. RESULTS A total of 99 subjects participated in the study out of which 39 were female. A total of 256 local anest...

BACKGROUND The EQ-5D health-related quality of life instrument comprises a health state classification followed by a health evaluation using a visual analogue scale (VAS). The EQ-5D has been employed frequently in economic evaluations, yet the relationship between the two parts of the instrument remains ill-understood. In this paper, we examine the correspondence between VAS scores and health s...

The aims of the present study were to develop and validate the Japanese version of the checklist individual strength questionnaire (CIS) which is used to measure prolonged fatigue not only in the general population but also in the working population. We obtained permission to use CIS from its author and translated the questionnaire into Japanese. Then, the Japanese version of the questionnaire ...

[Purpose] The aim of this study was to examine whether plantar flexor static stretching and dynamic stretching using an Aero-Step results in changes in foot pressure during gait in healthy adults. [Subjects] Eighteen normal adults were randomly allocated to either a dynamic stretching using an Aero-Step group (DSUAS) group (n = 8) or a static stretching (SS) group (n = 10). [Methods] The DSUAS ...

BACKGROUND National surveys in low-income countries increasingly rely on self-reported measures of health. The ease, speed, and economy of collecting self-reports of health make such collection attractive for rapid appraisals. However, the interpretation of these measures is complicated since different cultures understand and respond to the same question in different ways. OBJECTIVE The aim o...

We conducted an investigation to determine whether the visual analogue scale (VAS) method could be utilized in evaluating the lectures and pharmacy experience of the Division of Pharmacy and Health Sciences, Graduate School of Natural Science and Technology, Kanazawa University. Graduate students who had finished the 1-year pharmacy experience at the Kanazawa University Hospital were asked to m...

To investigate whether there are differences in patients' denture satisfaction when an implant placed in the midline of the edentulous mandible is loaded either immediately or three months later, after second-stage surgery. One hundred and fifty-eight edentulous patients received a single implant in the midline of the mandible. After randomisation, it was loaded either immediately after implant...

100 teens ranked pain experienced for their most recent "shot"on three different scales: casual 0-10 scale (mean 3.3), faces scale (mean 2.8), and 10 cm visual analog scale (mean 2.4). All pain scores showed wide variation (poor validity). Pain severity values were not equivalent across the different pain scales with the casual 10 scale most likely to overestimate pain values.
