[Purpose] To describe our newly developed Sedentary Behavior and Light-Intensity Physical Activity Questionnaire and examine its reliability and validity. [Participants and Methods] We identified and selected self-reported items through a literature review and interviews with 11 inactive individuals. Thirty-one individuals with lower limb prostheses and an expert panel assessed the content validity of the integrated items and identified 17 items. Patients who had undergone lower limb surgeries were regarded as inactive individuals, and 112 patients completed the questionnaire twice for test-retest reliability and wore an accelerometer for criterion validity. The ethics committee of Kyushu University approved this study (2019-126 and 2019-273). [Results] Item analysis was revised to the Sedentary Behavior and Light-Intensity Physical Activity Questionnaire-10 (six light-intensity physical activity and four sedentary behavior items) because of the floor effect. The test-retest correlation coefficient showed high reliability. Moderate to weak correlation coefficient was observed between the questionnaire and accelerometer (light-intensity physical activity 0.43 and sedentary behavior 0.20), and the Bland-Altman plots indicated no bias. [Conclusion] The Sedentary Behavior and Light-Intensity Physical Activity Questionnaire-10 had acceptable validity and reliability among inactive individuals and it could be used for studying light-intensity physical activity.[Purpose] We investigated how differences in pelvic angle in the posterior pelvic tilt sitting posture simultaneously affect the thoracic morphology and the respiratory function. [Participants and Methods] The participants were 18 healthy young males. We positioned the pelvis at 0°, 10°, 20°, and 30° of posterior tilt, following which the thoracic expansion volume ratio, thoracic spine tilt angle, and respiratory function were measured. We calculated the thoracic volume and thoracic spine tilt angle by measuring the amount of displacement of reflective markers attached to the thoracic area using the Vicon MX 3D-analysis system. Respiratory function was measured by spirometry. [Results] The expansion volume ratio decreased significantly in response to 10-30° posterior pelvic tilt sitting at the mid-thorax and 30° posterior pelvic tilt sitting at the lowest thorax. The upper thoracic spine level showed a change in anterior tilt at 10-30° posterior pelvic tilt sitting, whereas the lower thoracic spine level showed a change in posterior tilt at 30° posterior pelvic tilt sitting. Respiratory function was significantly lower at 30° posterior pelvic tilt sitting than at 0° posterior pelvic tilt sitting. A positive correlation between thoracic expansion volume ratio and respiratory function was found at 30° posterior pelvic tilt sitting. [Conclusion] Changes in thoracic spine tilt angle due to posterior pelvic tilt sitting may restrict the expansion of thoracic motion during respiration, thereby affecting respiratory function.[Purpose] The purpose of this study was to examine the test-retest reliability and minimal detectable change (MDC) of reach distance and movement angle analyses using Image J. [Participants and Methods] Thirty-eight healthy young males performed the functional reach test (FRT) twice, and their reach movements were recorded using a digital video camera. Image J was used to combine the digital photographs taken at the start position and maximum reach and to measure each movement. The measurements recorded were the movement distance of the third metacarpal bone (reach distance), anterior-superior iliac spine, and trochanter major, and the angles recorded were the acromion-malleolus lateralis, acromion-trochanter major, and trochanter major-malleolus lateralis. The reliability of all the measurements was analyzed using intraclass correlation coefficients (ICCs), Bland-Altman plots, and MDCs. [Results] The ICCs (1, 1) were >0.80 for all the outcomes. The Bland-Altman analysis revealed no systematic bias in any outcome. The MDC of reach distance was 18.3 mm. [Conclusion] Measurement using Image J for reach distance and movement angles in the FRT showed acceptable high test-retest reliability. selleck chemicals Measurement of the FRT and the MDC calculated in this study could be used as a reference for further research.[Purpose] We aimed to investigate students' awareness of their general physical activity and current physical activity habits. [Participants and Methods] One hundred and eighteen undergraduate students in rehabilitation courses volunteered to participate in this survey. The participants were required to answer a questionnaire related to their health awareness and physical activity habits. A χ2 test was used to demonstrate the relationships between each category of the selected items. [Results] Undergraduate rehabilitation students felt very or moderately healthy when asked to subjectively describe the current condition of their health. Most of them liked and had more interest in exercise or sports activities. However, more than 60% of them felt that their participation in physical activities had decreased since they entered college. [Conclusion] Undergraduate students in rehabilitation courses lacked motivation to exercise and participate in physical activities in college. Students who did not have a habit of exercising or participating in sports activities may have lacked motivation because they were busy with school; however, they had a high level of positivity towards exercise or sports activities. Therefore, it is important for them to actively participate in exercise and/or physical activity with a specific purpose in mind.[Purpose] The purpose of this study was to determine the concurrent validity of Wii Fit center-of-pressure parameters with Clinical Test of Sensory Integration for Balance and to evaluate the discriminant validity of the Wii Fit center-of-pressure parameters for adults and the elderly for the assessment of postural sway. [Participants and Methods] This study used an observational cross-sectional correlational design. All 70 participants were required to complete a questionnaire for eligibility screening, followed by a center-of-pressure assessment using three Wii Fit balance activities (snowboard slalom, ski slalom, and balance bubble) and Clinical Test of Sensory Integration for Balance using a force platform. [Results] For center-of-pressure assessment, our results showed there was concurrent validity of Wii Fit ski slalom and balance bubble with Clinical Test of Sensory Integration for Balance conditions 6 and 4, respectively. Our results also demonstrated that the three Wii Fit balance activities selected in this study could be used to discriminate between adults and the elderly.
