Abstract

Introduction: Hand grip strength is an important parameter in evaluation of hand function and it is one of the most reliable clinical measures of human strength. Majority of studies have sampled adults only and those which included adolescents used pneumatic and hydraulic manometer, Martin vigorimeter, etc. The Jamar dynamo meter is considered as the ‘gold standard’ for hand grip strength measurement.
Aim: To quantify normative values of hand grip strength in adolescents of Gujarat using Jamar dynamo meter.
Materials and Methods: 160 children from three schools were included in this observational study after receiving informed written consent. The anthropometric variables and hand dominance were recorded. Hand grip strength was measured using the Jamar dynamometer. The average of three trials was taken as final reading.
Results: Optimal grip strength was determined in both genders for dominant and non-dominant hands. Un-paired t-test was used to compare hand grip strength of dominant hand and non-dominant hand which showed that there was not significant grip strength difference between dominant and non-dominant hand.
Conclusion: This study has quantified the normative values of grip strength which can be used as a reference measure value for detecting the abnormality in hand grip strength in Gujarati population of same age.
