Background: An accurate, quantifiable assessment of hand grip strength (HGS) can predict overall strength and health with a good predictor for identifying populations at higher risk for any medical conditions like rheumatoid arthritis, neuromuscular diseases and stroke that helps clinicians establish realistic treatment goals and provides treatment outcome data. The purpose of the study is to determine the percentile scores of HGS of healthy adult individuals of various age groups using Jamar dynamometer and modified sphygmomanometer. Methods: This descriptive study measures HGS using Jamar dynamometer and modified sphygmomanometer obtained from one hundred twenty healthy participants 20 years old and above. Comparative analyses of the 2 apparatuses were conducted using One-Way ANOVA. The reference intervals at different percentiles were calculated using the Clinical and Laboratory Standard Institute (CLSI) guidelines. Results: Grip strength (GS) using Jamar dynamometer (JD) and modified sphygmomanometer (MS) among younger (20- 29 years old) participants, the 50th percentile (Q2) JD score was 28.29 kg with an equivalent MS score of 161.38 mmHg, were significantly higher compared to those across older age groups especially among the ≥70 years old with a JD Q2 score of 16.74 kg and MS Q2 score of 101.33 mmHg. These findings suggest that HGS decreases with increasing age. Conclusion Scores obtained from this study can serve as preliminary baseline values or guide for interpreting GS measurements.
