Abstract
BACKGROUND: Problems with COVD-19 are not limited to the infection itself, but also include the secondary health damage arising from the prolonged self-restraint, which has affected all age groups in the Japanese population. Numerous studies have reported clear evidence of the secondary health damage. Published reports cover a wide range of damages, from locomotive dysfunction caused by decreased physical activity to decreased cognitive function and changes in eating and oral functions, and further to decreased opportunities for social participation. Such damage can also lead to worsening of so-called frailty. Under this circumstance, orthopedic surgeons conducted a questionnaire survey to determine the physical changes observed after the start of the COVD-19 self-restraint period. In this article, we report findings of the survey, along with some literature considerations. METHODS: The survey was started two months after the state of emergency in Japan was lifted, July 20 to August 12, 2020 (16 days total). And the analysis was conducted by simple and cross tabulation. RESULTS: Valid responses to the questionnaire were obtained from 12,254 participants. Approximately 40% of the subjects felt a lack of physical strength (Corona stress), with the percentage peaking in high school, in the elderly it remained rather below average. On the other hand, locomotive dysfunction (Corona locomo) increased with age, independent of physical activity, and was not correlated with Corona stress. CONCLUSIONS: Japanese citizens need to change their behaviors for the purpose of improving their exercise and lifestyle habits towards shifting to a new lifestyle norm. Looking ahead to the ``With Corona'' era, it is considered necessary by selecting a tailor-made training method suitable for each age group.
