Comparison of shoulder strength assessment in scaption with an isometric dynamometer and a weighing machine: a pilot study

摘要

BackgroundStrength testing is an important aspect of shoulder examination. To date, strength assessment has many limitations. There is no single standard instrument for measuring, and various current devices have problems in reliability, accuracy, and cost. This study compared the results of an innovative and simple method of strength testing (weighing machine) with an existing method (isometric dynamometer).
