MyoBock: Evaluation of the myosignals
As part of a myoelectric, prosthetic fitting of the hand or arm the evaluation of the myosignals must be completed prior to definitive prosthesis manufacture and fitting. Preliminary evaluation will help determine the ideal electrode position and gain, as well as the most appropriate switching mode.

A careful, accurate evaluation of the myo-signal and the corresponding adjustment is essential. This will affect the definitive fitting and final result.

Once both myosignals have been evaluated, and the switching method is defined, check and train the settings with the myosimulation in PAULA software. This ensures that the user can control the prosthesis independently and reliably in everyday life with the selected adjustments.

By completing the evaluation you have laid the foundations for successful prosthesis fitting and use.

Myoelectric is the technical term for the electrical voltage generated in muscle cells in the microvolt range, which can be measured on the skin surface and used via electrodes to control prostheses. Myoelectric prostheses are powered by a battery and set in motion by the contraction of a muscle.
