The feasibility of using the go/no-go task as a dementia screening test assessed with a cross-sectional design.

The Mini Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), and Frontal Assessment Battery are screening tests for dementia. The go/no-go task offers an alternative approach for evaluating dementia patients. However, its role in screening for dementia remains unclear.

Simultaneous Measurement of Ear Canal Movement, Electromyography of the Masseter Muscle and Occlusal Force for Earphone-Type Occlusal Force Estimation Device Development.

We intend to develop earphone-type wearable devices to measure occlusal force by measuring ear canal movement using an ear sensor that we developed. The proposed device can measure occlusal force during eating. In this work, we simultaneously measured the ear canal movement (ear sensor value), the surface electromyography (EMG) of the masseter muscle and the occlusal force six times from five subjects as a basic study toward occlusal force meter development.

A quantitative assessment of the mechanical effects on the lumbar spine and the effects on straight leg raising and lumbar flexion of segmental sustained rotation.

[Purpose] This study were to examine the strength and relative direction of the applied force from lumbar segmental sustained rotation (LSSR) on the lumbar spinous process, and to clarify the effects of LSSR on straight leg raising (SLR) and lumbar flexion (LF). [Subjects] 18 pain-free healthy adults volunteered for this study. [Methods] Applied force and direction were measured between the L5-S1 segments using tri-axial pressure sensors.

Examination of improvements in "hay fever masks" based on a preference survey.

The long-term goal of this study is to make suggestions for improvements both in the functionality and the comfort of hygiene masks. As basic research, we conducted a survey of young A to ascertain problems with masks used for hay fever in 2009. Main questions were: (1) "Do you have HF?" (2) "What HF symptoms do you have?" (3) "Do you like, dislike or neither like nor dislike wearing a hygiene mask?" (4) "What are the reasons for that?" The ratio of symptomatic people of HF was 41% in this research.

An investigation of the use of hay fever masks for the youth.

Specific examinations of university students in Japan revealed numerous people affected by hay fever among the younger population, various measures for hay fever prevention and dissatisfaction with commercially available hay fever masks. Questionnaire replies from 1519 students demonstrated the following results: (1) those with hay fever accounted for 36.5% of males and 44.
