Abstract: A muscular strength characteristic evaluation method evaluates a muscular strength characteristic of a limb 3 including a first rod L1 having a base end supported by a first joint Ji, and a second rod L2 supported by a free end of the first rod via a second joint J2. The muscular strength characteristic evaluation method includes the following steps. In Step ST1, a free end of the second rod is moved at two or more different velocities va, vb, and vc in a predetermined direction, and an output at the free end of the second rod is respectively measured at a predetermined position O. In Step ST2, a function indicating a relationship between the output and the velocity in a direction is calculated based on the output and the velocity. In Steps ST3 and ST4, the muscular strength characteristic is evaluated based on the function.
