Dynamometers are used to measure muscle strength in a wide range of activities. Hand dynamometers, for example, are useful in measuring gripping and pinching strength. You can also use dynamometers to measure the strength of larger muscle groups using pushing, pulling and lifting tests.
In selecting a hand dynamometer for use in your clinic, we suggest consideration of the issues below.
An important factor in measuring gripping strength is the ability to measure strength in a wide range of gripping positions. The positions should range from a close grip to a wide one. Measuring gripping strength in this way produces more accurate results.
When measuring pinching strength, it is again important to use a dynamometer that is capable of measuring strength in a variety of positions. In this case, you will ideally need one that is capable of measuring palmar, key and tip pinch strength. Again, this will result in a more accurate overall evaluation.
