Key facts

PhenX - muscle strength protocol 150301
Hand grip strength is measured with a device called a hand-held dynamometer. The technician follows a script and asks the participant about hand surgery or pain that may influence the results. The technician asks the participant to sit in a chair and rest his/her arm on the table with the elbow on top of a mouse pad and arm held at a right angle. The technician adjusts the grip size of the dynamometer to the participant's hand size and explains how the device works. The participant squeezes the dynamometer twice during practice trials. Now, starting with the right hand the participant is asked to squeeze as hard as possible. Two trials are attempted with each hand with all results recorded on a form. Results should be recorded to the nearest 2 kilograms. This protocol is specific to the Jamar dynamometer. The following dynamometers have also produced valid and reliable hand grip test resultsTakei Grip A dynamometer, Model 68812, Lafayette Instruments 50//100 and 100 kg / 220lb Hand Grip Dynamometer set, and TKK digital hand dynamometer (TKK 5101 Grip-D Model). The grip setting on the dynamometer (adjustment for hand size) should be recorded, especially for repeated (longitudinal) measurements. The technician should utilize the dynamometer manufacturer's user manual for proper use and maintenance of the dynamometer and check the calibration of the device with known weights once a week.
