Evaluating the reliability of a novel neck-strength assessment protocol for healthy adults using self-generated resistance with a hand-held dynamometer.

Purpose: To evaluate the intra- and inter-session test-retest agreement of a novel neck-strength assessment protocol using a hand-held dynamometer.

Background: A literature review found a lack of neck-strength assessment protocols that are both portable and reliable. Hand-held dynamometry is a portable and inexpensive method of assessing muscle strength, but it is not commonly used for neck-strength assessment.
