Evaluating the Influence of Gravity on Shoulder Strength Measures Assessed via Handheld Dynamometry.

Context: Handheld dynamometry is a feasible, reliable, and cost-effective method for assessing shoulder strength. One limitation to this tool is the lack of standardized testing protocols and specified shoulder strength test positions. Although it is recommended that strength tests be performed in a gravity-eliminated position, this may not always be a feasible or practical testing protocol.
