Materials: (1) Tape measure

Methods:

  • The patients stand on the leg to be tested, hop, and land on the same limb as far as possible
  • The distance hopped, measured at the level of the great toe, is measured and recorded to the nearest centimeter from a standard tape measure that is permanently affixed to the floor.
