The Otto Bock System Hand caters specifically to these user requirements. Hands consist of three parts: the hand chassis with hand mechanism, the shaped inner hand and the cosmetic glove. These together provide both functionality and a natural appearance and are available in 18 colours. Single-Cable System Hand The Single-Cable System Hand is suitable for all cable-controlled prostheses. The hand is deliberately opened by means of a cable and closes independently with concurrent locking. A threaded stud or chassis connects the hand with the lower arm. The Single-Cable System Hand is available with a perlon or steel cable that is attached at the inner side of the hand (inner cable) or at the back of the hand (outer cable). Double-Cable System Hand The Double-Cable System Hand is suitable for all cable-controlled prostheses. The hand closes following a deliberate pull of the cable. A subsequent adjustment pull increases the grip force and locks in any grip position. Through renewed activation of the cable, the hand becomes released and opens independently (double cable). A threaded stud or chassis connects the hand with the lower arm. The Double-Cable System Hand is available with a perlon or steel cable that is attached at the inner side of the hand (inner cable) or at the back of the hand (outer cable).
