Testing of the muscle strength of individual muscles such as the deltoid, neck flexors or trapezius with the Oxford grading scale was conducted taking into account the combined nerve innervations of the respiratory muscles and the deltoid, neck flexors and trapezius muscles via the corticospinal pathway and the possibility of interneuron activation (C1 - C6).
At the optimal location, the input-output curve of the corticospinal pathway was measured by increasing the TMS intensity, represented as a percentage of the maximum current that can be discharged into the coil, in steps of 5% until the MEP reached its plateau.
(29) This stimulates the corticospinal pathway, and the muscle MEP is recorded distally using needle electrodes placed over the skin of the target muscles groups (Fig.
Moreover, it has been reported that Ia afferent input has the ability to excite the corticospinal pathway (Carson et al., 2004) and activate the cortical motor areas (Lewis et al., 2001).
