do the adolescents’ physical activity and screen time during the covid-19 quarantine correlate to their upper extremity abnormalities and anxiety?

Background: this study examines the prevalence of upper extremity abnormalities during covid-19 quarantine. it emphasizes the role of physical activity and screen time in these abnormalities in male adolescents. the relationship between these components and anxiety was also examined.method: this descriptive-correlational study was performed on 150 13-15-year-old boys. upper extremity abnormalities are measured using image j software and spinal mouse. physical activity, screen time, and anxiety are assessed by the use of standard questionnaires.results: means of age and bmi were 22.86 and 22.48, respectively. the results showed that 70 patients (47%) had forward head posture, 51 patients (34%) had kyphosis, and 11 patients (7%) had lordosis. in addition, the results showed that physical activity and screen time were significantly correlated to forward head and kyphosis (all t>1.96). also, physical activity, screen time, and upper extremity abnormalities were significantly associated with anxiety (all t>1.96).conclusion: the results indicate that upper extremity abnormalities, including forward head and kyphosis, are relatively common in male adolescents during covid-19 quarantine. also, physical activity and screen time may impact these abnormalities.
