Today when we visited with Dr. Brewer we focused on discussing the different types of grip and how this can be applied to the use of prosthetic. There are six different types of grasp: hook, lateral, palmar, cylindrical, spherical, and pincer. The hook grasp is the type of grasp used when preforming tasks like holding a bag. The lateral grasp is the type of grasp used for holding very thin objects such as paper. The palmar grasp is the type of grasp used for holding a writing implement or eating utensil. The cylindrical grasp is the type of grasp used for holding something similar to a cup. The spherical grasp is the type of grasp used for holding objects such as a ball. The pincer grasp is the grasp used for holding very small objects such as a ball bearing. The concept "Degrees of Freedom" refers to the idea of how many different ways a hand can move. The actual number of degrees of freedom is highly controversial it can range anywhere from 21 to 27 degrees of freedom.
