Normal Baseline Values for Isometric Shoulder Strength in Scaption for Healthy Filipino Individuals in the 20-30 year Age Group

Abstract

INTRODUCTION: Isometric shoulder strength is vital in the management of individuals suffering from shoulder diseases such as rotator cuff tears. Normal values for the working Filipino population who are at risk of developing shoulder problems are lacking. The objective of this study was to determine the isometric baseline isometric shoulder strengths in scaption of healthy Filipino individuals aged 20-30 years old without a history of a shoulder injury. MATERIALS AND METHODS: This is a cross-sectional descriptive study measuring the isometric strength values using the handheld IDO isometer of dominant and nondominant 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 nondominant 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.
