| Abstract | ||
| Background: Due to scapular mal-alignment and forward head posture, heavy smartphone use has an influence on shoulder scapular muscle strength. The purpose was to investigate how smartphone addiction affected the strength of scapular muscles in adults. A cross-sectional observational analysis. Methods: A total of 150 individuals, ranging in age from 18 to 30 (mean ± standard deviation was 34.83± 4.07years), were included. The smartphone addiction scale short version (SAS-SV) was used to assess smartphone addiction, while a hand-held dynamometer was used to assess scapular muscle strength. Results: Mann-Whitney test showed that there was significant difference between isometric scapular muscles strength at both sides except for upper trapezius (UT) at the left side. Spearman correlation showed weak negative correlation between SAS score and isometric strength of UT r =-0.17, p = 0.4, middle trapezius (MT) = -0.20, p = 0.1, lower trapezius (LT) r = -0.29, p = 0.00, serratus anterior (SA) r = -0.20, p = 0.01 on the right side and isometric strength of MT r = -0.28, p = 0.00, LT r = -0.29, p = 0.00 on the left side. On the other hand, there were no significant correlation between SAS score and isometric strength of UT r = -0.14, p = 0.097 and SA r = -0.13, p = 0.1 on the left side. Conclusions: Smartphone addiction doesn’t cause loss of scapular muscle strength in both sides but people may use one side more than the other that may induce scapular muscle imbalance and shoulder dysfunction. | ||
