Hand Strength - Grip and Pinch Dynamometry

Grip and Pinch Dynamometry

To create more quantitative assessments of hand muscle strength, dynamometers have been developed. These dynamometer measurements are more sensitive to change compared to manual muscle testing and render outcome on a continuous scale. In clinical evaluation and research studies on patients with hand problems, muscle strength measurements are usually based on grip strength and pinch strength dynamometry. The most commonly used grip and pinch dynamometers are the Jamar dynamometers and similar devices by other manufacturers. In several patients groups, these measurements have a good reliability and validity. In addition, grip- and pinch strength are functionally relevant to measure the combined action of a large number of intrinsic and extrinsic hand muscles as well as the combined action of a number of different joints. By comparing outcome with normative data, the amount of muscle strength loss can be determined.

Famous quotes containing the words grip and/or pinch:

    While the State becomes inflated and hypertrophied in order to obtain a firm enough grip upon individuals, but without succeeding, the latter, without mutual relationships, tumble over one another like so many liquid molecules, encountering no central energy to retain, fix and organize them.
    Emile Durkheim (1858–1917)

    There cannot be a pinch in death
    More sharp than this is.
    William Shakespeare (1564–1616)
