Strength testing using hand-held dynamometry

The reliability of strength measurements obtained during clinical examination has been the subject of many investigations. The need for an accurate, quantitative method to determine strength in multiple settings and environments is important for both examination and treatment. The purpose of this paper is to provide a review of the existing literature investigating the reliability and concurrent validity of hand-held dynamometry. A thorough review of the literature revealed that held dynamometry is a suitable alternative to traditional manual muscle testing as it exhibits good-to-excellent reliability, provides objective ratio data, and has the portability to be used in multiple environments. Hand-held dynamometry is a reliable method to determine the strength status and change status provided testing protocols are consistent.
