Joint angles

Definition

Joint angles refer to the specific degrees of rotation at the joints of a limb, such as those found in arms and legs. These angles are crucial for determining the position and movement of prosthetic limbs, as they provide essential information for controlling the prosthetic's actions, allowing users to perform tasks that require precision and coordination.
