Analysis of maximal grip strength using three types of dynamometer

Maximal Grip Strength (MGS) is regarded as a good indicator of upper-limb strength or even of the whole neuromuscular system. Two popular dynamometers used for MGS evaluation are the Jamar and the Martin Vigorimeter. The Myogrip is a new digital dynamometer designed for testing very weak patients suffering from various neuromuscular disorders. It offers a sensitivity, precision and accuracy adapted to such a population. The main aim of this study was to compare grip strength assessment using these three dynamometers. Sixty nine healthy undergraduate students volunteered for the study. They were required to exert their MGS using the Jamar, the Vigorimeter and the Myogrip in a random order. After 14 days, 47 subjects participated in a second test.
