Control over force
The three fundamental axes of movement (Anterior-Posterior, Adduction- Abduction, Internal rotation-External rotation) are much too important to be
controlled and adjusted with the same force intensities.
The muscles that are responsible for the anterior-posterior movement of the
shoulder, such as the deltoid or the biceps brachii muscle, develop a force
that is by far inferior compared to the muscles that are responsible for
Adduction-Abduction movement (e.g. the pectoralis major muscle).
Therefore, in order to differentiate the intervention modes on the different
muscle sections correctly and also in order to expand the MJS implementation
potential, the MJS has been provided with three, completely independent
force control and adjustment units. One unit is for Anterior-Posterior movements, one is for Adduction-Abduction movements and, finally, one is for Internal rotation-External rotation of the shoulder.
For monitoring completeness, without any compromise to the perfect control of
motorial exercises.
