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.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.
Highlights
Isometric shoulder strength is vital in the management of individuals suffering from shoulder diseases such as rotator cuff tears
The male gender compared to the female gender shows a significant difference in isometric shoulder strength (p-value = 0.002) male showing stronger isometric strength
Cools et al measured the eccentric and isometric shoulder strengths for internal and external rotation of 201 overhead athletes aged 18 to 50 years old with equal male and female participants results showed that strength differences favour the dominant side and the male gender[8]
Summary
Isometric shoulder strength is vital in the management of individuals suffering from shoulder diseases such as rotator cuff tears. The objective of this study was to determine the isometric baseline isometric shoulder strengths in scaption of healthy Filipino individuals aged 2030 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. Strength testing is performed to assess the ability of the patient to maintain a degree of tension in the voluntary muscle against a force or resistance[5]. It can be tested using the traditional manual muscle grading and assigning a grade from 0 to 53,5. Vital in everyday life, little is known about the expected normal baseline of shoulder strength in this position
