Norms for Adult Grip Strength
A recent study by Dr. Virgil Mathiowetz indicates that “... individuals using the Baseline®
dynamometer are justified in using the normative data collected with the Jamar®
dynamometer...”
For each test of grip strength, the subject was seated with shoulder adducted and
neutrally rotated with the elbow between 0˚ and 15˚ ulnar deviation.
The standard test protocol used the mean of three strength tests as a resultant score. A
score was taken with both the dominant (right) and non-dominant (left) hands.
The rest results show a relationship between:
• hand strength vs. age
• hand strength of men vs. hand strength of women
• dominant hand strength vs. non-dominant hand strength
