Functional electrostimulation through a sequence of muscle tensions enables the performance of complex movements. To prepare the exercise, place the indicated electrodes on the appropriate muscles, according to the instructions in the illustration.

The exercise aims to open the hand and then to close it. Before the treatment the EMG calibration is needed. The whole sequence of movement starts when wrist extensors are above the threshold line followed by a pause and then the flexion of the fingers and thumb. To make this task more functional use the item, like a plastic bottle or a ball.
