Strength Isometric Test: Wrist Grip Strength

To test grip strength isometric strength with a Muscle Meter, you can follow these steps:

1. Have the client seated in an upright position, with the elbow tucked into their torso and flexed to 90 degrees. The elbow should also be in a neutral position of pronation and supination.
2. Once set, hand the client the MAT Gripper with the Muscle Meter wedged inside.
3. Queue the client to squeeze the Gripper as best as they can, holding for 2-3 seconds to achieve peak force production.
4. Upon completion, hit save in the Measurz app and compare to the other side.

Normative data for grip strength isometric strength measured with a handheld dynamometer can vary depending on factors such as age, sex, and population studied. However, here are some general normative data for healthy adults:

• Men: Average of 54-64 kg (119-141 lbs)
• Women: Average of 34-44 kg (75-97 lbs)
