Abstract: A method for deriving isokinetic measurements of the moment applied by a body portion while the body portion performs a pivotal or flexing motion at a given angular velocity about an effective pivot axis. The method uses a linear dynamometer configured for performing isokinetic measurements over a predefined range of motion along a linear path. First, the linear dynamometer is deployed with its linear path substantially tangential to a circle of given radius about the effective pivot axis for measuring force applied by the body portion. The linear dynamometer is then used to measure a force profile applied by the body portion over a predefined range of motion at a predefined linear velocity. This force profile, the linear velocity and the radius are then used to derive data for the moment applied by the body portion and the corresponding angular velocity.
