Hand strength testing is frequently used for clinical decision-making and outcome evaluation in evidence-based medicine.
It is used to diagnose diseases, to evaluate and compare treatments, to document progression of muscle strength, and to provide feedback during the rehabilitation process.
In general, hand strength measurements can be divided into manual muscle testing and dynamometry.
Finally, with the 6-point ordinal MRC scale, it is difficult to identify relatively small but clinically relevant changes in muscle strength.
These dynamometer measurements are more sensitive to change compared to manual muscle testing and render outcome on a continuous scale.
