The Effect of Visual Feedback of Head Angles With Using a Mobile Posture-Aware System on Craniocervical Angle and Neck and Shoulder Muscles Fatigue During Watching the Smartphone

The purpose of this study was to assess the intra-rater and inter-rater reliability and validity of pelvic tilting angle measurements using a smart phone-based inclinometer (Clino) compared to a palpation meter (PALM) in the standing and sitting position. This study used an interchangeable method with Clino to measure the pelvic tilting angle in the standing and sitting positions. Methods: Twenty healthy subjects were recruited. Measurements of the pelvic tilting angle in the standing and sitting positions were obtained by two examiners using the Clino and PALM. A resting session was conducted 10 minutes later to assess the intra and inter rater reliability. To assess validity of the measurement using Clino, a PALM was used as the gold standard. The intra-class correlation coefficient (ICC) was used to determine the intra and inter rater reliability of Clino and a PALM. To assess the validity, the Pearson correlation coefficients were used for two measurement techniques to measure the pelvic tilting angle in the standing and sitting positions. The statistical significance was set to α= 0.05. Results: Measurements of the pelvic tilt had high inter-rater reliability in the standing (ICC= 0.82) and sitting (ICC= 0.88) positions using Clino and intra-rater reliability in the standing (ICC= 0.87) and sitting (ICC= 0.91) positions using Clino. Measurements of the pelvic tilt had high validity by a comparison of PALM and Clino in the standing (r= 0.83) and sitting (r= 0.89) positions (p< 0.05). Conclusion: The use of Clino can be recommended as a tool to replace the PALM and measure the pelvic tilt angle in the standing and sitting positions while maintaining the clinical reliability and validity.

This study examined the effects of social distancing in COVID-19 on musculoskeletal problems and the quality of life. Methods: One hundred and thirty-five subjects participated in this study and responded to an online survey on stress from the social distancing in COVID-19, computer and smartphone usages, musculoskeletal pain, and quality of life. The stress from social distancing was assessed by a Visual Analogue Scale (VAS). The Neck Disability Index (NDI), Oswestry Disability Index (ODI), and Boston Carpal Tunnel Questionnaire (BCTQ) were provided to assess the musculoskeletal pain, and Short Form-36 (SF-36) was provided to assess the quality of life. Frequency analysis, descriptive statistics, Pearson's correlation coefficient, and independent t-test were used for data analysis. Results: Statistically significant, but low positive correlation stress from the social distancing (VAS) and NDI (r= 0.19, p< 0.05) and ODI (r= 0.18, p< 0.05), and negative correlation between stress from the social distancing (VAS) and SF-36 (r= -0.17, p< 0.05). The NDI score was significantly greater in the group with high stress than in the group with low stress from social distancing (p< 0.05). Conclusion:This study is meaningful in that it evaluated, through the physical therapy approaches, the potential side-effects on physical and mental health in various social changes caused by COVID-19. The results of this study may be used as basic data in future studies related to COVID-19.
