In order to make sure you capture the most accurate data for a hand grip strength test there are several key procedures you must consider. 

• First off, make sure the patient is in a comfortable sitting position with their shoulder abducted and neutrally rotated. Angle of the elbow should be kept as close to 90 degrees as possible.
• The forearm should also be in a neutral position with the wrist between 0 and 30 degrees dorsiflexion while also between 0 and 15 degrees ulnar deviation.
• Instruct the patient to grip the hand dynamometer with their fingers around the second handle with the readout dial pointing away from their body. The administrator of the test should lightly grip the readout dial in order to prevent and accidental dropping of the device.
• Once the patient is comfortable instruct them to grip the device as hard as they can for 4-5 seconds and relax. It is best to perform this part of the test 3 times or more to generate an average grip strength reading. 
• Repeat the same steps with the patients other hand and use the chart below for normative data for men and women ages 6 - 75+
