  • This reaching process forces the user 100 out of balance, compromises the structure of the shoulder and arm, and forces the shoulder, elbow and wrist joints into a non-neutral position while loading or applying weight to the cane in order to take a step forward.
  • By having to move the arm away from one's center of gravity the user cannot use the full strength of his or her body to take a step forward.

  • the handle 304 is shown to have about 18.5 degrees of articulation 330 with respect to the leg (alternatively, this can be described as articulation or pivoting of the leg with respect to the handle). It will be appreciated that the degree of articulation can vary depending on the user's strength and needs. In some embodiments, the degree of articulation can be up to 45 degrees. In some embodiments, the degree of articulation can be from about 5 degrees to about 40 degrees. In some embodiments, the degree of articulation can be from about 10 degrees to about 25 degrees. In some embodiments, the degree of articulation can be from about 15 degrees to about 20 degrees.
