Material and Methods: This is a cross-sectional descriptive study measuring the isometric strength values using the handheld IDO isometer of dominant and non-dominant shoulder of healthy Filipino individuals aged 20 to 30 years old.
Results: There is no significant difference in the mean isometric shoulder strength between the dominant and non-dominant arm for both sexes. The male gender scored higher values compared to the female gender and is statistically significant.
Conclusion: There is no difference in isometric shoulder strength between the dominant and non-dominant shoulder. Strength differences favour the male gender.
