| Chronology of Development |
|
The commercially available grip handles are not convenient for the measurement of grip strength of weak patients (<20 N). We decided to develop a grip handle sensitive and accurate for these patients. First prototype in 2002. Second prototype in 2006. Study of reproducibility and comparison with Jamar and Martin Vigorimeter on 80 subjects. Study on the effects of handle size and elbow position on 24 subjects. Norms under developement on 450 subjects aged from 5 to 80. Complementary study on reproducibility and repeatability on 120 subjects ongoing.

Device
|
| Description |
|
Myogrip is built around a strain gauge and measure grip strength with a sensitivity of 0.01 daN (i.e. approximately 10 g) and a precision of 0.05 daN (50 g). This dynamometer can work according to four modes: instantaneous display; max force display; Bluetooth or RS-232 connection to a computer.
