Muscle Strength Norms 18 muscle functions · Harbo et al. 2012

Muscle strength compared with reference values from healthy adults

Isokinetic and isometric peak torque of 18 muscle functions, measured on a computerized dynamometer: % of predicted and z-score against the lower limit of normal (Harbo et al. 2012).

Measured peak torque

Enter only the functions tested. Reference protocol: dominant arm, non-dominant leg.

Result

Shaded zone: below the lower limit of normal (LLN, 5th percentile of healthy adults, z < −1.645). z = (measured − predicted) / residual SD of the sex-specific equation.
