A hand grip dynamometer is a tool used to measure a person’s hand grip strength and ability. Although styles and manufacturers vary, there are three basic types of dynamometer, namely a hydraulic meter dynamometer, a pneumatic dynamometer, and Myogrip strain gauge dynamometer. Each of these dynamometers is primarily used in the health care sector to assist in assessing and rehabilitating patients in terms of hand movement and strength.
One of the most common types of hydraulic dynamo is called a JAMAR grip dynamometer. This instrument generally has a curved metal or plastic grip that a person holds in his hand and squeezes. The handle itself does not usually move, but a hydraulic mechanism measures the pressure exerted by the handle, which is then displayed on a gauge located on top of the apparatus. Some models do not utilize a target, but instead have a digital display. The JAMAR grip dynamometer is considered one of the most accurate and reliable models in the industry.
Another type of dynamometer is known as a pneumatic hand dynamometer. This type of grip dynamometer uses a rubber press fit on the end of a tube. The patient presses the ball and the force exerted is then measured by means of a meter at the other end of the tube. There are models that use digital displays for this kind of grip dynamometer as well. The most commonly used pneumatic dynamometer is called a Martin Vigorimeter and is the basis of many health institutions for their ease of use and accuracy.
The Myogrip dynamometer is a type of grip dynamometer that uses a strain gauge. This type of dynamometer is smaller than both the JAMAR or Martin vigorimeter. It is also much more sensitive and is used primarily with patients who are weak, weak, or who otherwise have very poor grip strength.
Regardless of the type of grip dynamometer, most will measure grip strength up to 200 pounds (about 90 kg). Each dynamometer can be used in a variety of ways to perform a variety of different tests, each measuring different properties. The most versatile grip dynamometer in this regard is the JAMAR, or hydraulic type dynamometer. While mainly used in the medical field, both the hydraulic and pneumatic type grip dynamometers are available to the general public, and are used by people interested in measuring and increasing their grip strength for professional or other reasons. Due to its nature, Myogrip dynamometer is used almost exclusively in the health sector.
