Fine motor control can be measured with the Functional Dexterity Test (FDT) and the 9 Hole Peg Test (Aaron & Jansen, 2003; Oxford Grice et al., 2003). Grip and pinch strength are measured with a dynamometer and pinch gauge respectively, which are tools that measure strength in both pounds and kilograms (McQuiddy, Scheerer, Lavalley, McGarth, & Lin, 2015). The normative data for these tools from the mid-1980s is still being used in practice today and that needs to change.
