Hand grip strength (HGS) measurement is extensively used in many areas of medicine and sport science as a functional test of overall strength. It is also used as an indicator of general health and nutritional status. Widespread use of the isometric HGS test results from its practical utility and feasibility, such as availability and high reliability of the measurements. In addition, evaluating HGS using a hand-held dynamometer is non-invasive, inexpensive and simple to administer [1].
Selected clinical indicators for grip dynamometer testing include; Cervical injuries where there is reason to suspect nerve root injury, suspected tears of the brachial plexus, carpal tunnel syndrome (median nerve neuropathy), rheumatoid arthritis and any other presenting condition that includes grip weakness.
The grip dynamometer has 5 adjustable hand placements. Patients normally generate their maximum force when the dynamometer handle is at the 2nd setting, followed by the 3rd, 4th, 5th and 1st setting [2].
The video explains in detail the various grip positions.
