Periksa dan hitung jumlah DOF pergelangan tangan Anda.
Examine and count the number of DOF of your wrist. Answer: In human wrist has one joint,it’s a type universal joint and it can revolute in both x and y axis,therefore the degree of freedome is 2. The healthy human wrist is capable of three degrees of freedom (DOF). These DOFs are pronation/supination, flexion/extension, and radial/ulnar deviation (Figure 1). Radial/ulnar deviation is sometimes called abduction/adduction (respectively), and pronation/supination may be called wrist rotation. Note that each DOF is a paired set of motions (e.g. flexion/extension), involving positive and negative rotations from the neutral pose about the same axis. Here after, when only one of the motions per axes is named, we refer to both motions (e.g. pronation implies both pronation and supination). It should be noted that pronation/supination does not occur at the carpal bones of the wrist, but actually occurs within the forearm, as the radius crosses over the ulna in a twisting motion when moving from
