The use of myoelectric command is often difficult to apply to congenital pathologies
of the upper limb, which alternative solutions such as pressure sensors or common
microswitches are often used. In such cases, prosthesis command entails the use of
the same techniques used with the myoelectric method, in other words, the activation
of the various hand, wrist and elbow functions by means of a cyclic system or one
based on subdividing the signal detected by the sensors into various levels. In movements
involving more than one joint, only one function is activated at any one
time, which, although extremely safe, often makes these operations lengthier and
sometimes unnatural. Therefore using a mini-joystick for prosthesis control can prove
extremely convenient as it permits combined control the functions of the artificial
limb simultaneously according to the direction in which the joystick is moved.
