Strapped for Strength: A Comparison Study of Dynamometry Techniques to Evaluate Knee Extensor Strength in Inclusion Body Myositis.

ABSTRACT:

Introduction/aims

Accurate measurement of knee-extensor strength in people with inclusion body myositis (IBM) is vital to track disease progression and provide a standardized outcome for clinical trials. Isokinetic dynamometers are the current gold standard tool for measuring knee-extensor strength. A less costly, more portable tool would have more widespread clinical and research applications. Current practice is to use handheld dynamometry, but there are concerns around the accuracy of this method as it relies on precise operator technique. This study investigates whether stabilization of the handheld dynamometer with a strap (SSHD) improves agreement with the isokinetic dynamometer (IKD) for measurement of knee-extensor strength in IBM participants compared to operator-stabilize
