INTRODUCTION:
Hand-held dynamometry (HHD) is a technique for evaluating muscle strength, conducted through a sustained maximum isometric contraction. These dynamometers are small and less in weight for easy handling and applicability1-5. Such characteristics make the use of this instrument viable in the most diverse environments and populations6,7. However, there is still little research investigating the psychometric properties of the evaluation method adapted for this instrument in measuring upper limb muscle strength8-12.
The aim of this research was to compare the reproducibility and reliability results of muscle strength evaluation with a hand-held dynamometer using the fixed and non-fixed method.
