From: Central neuromuscular dysfunction of the deltoid muscle in patients with chronic rotator cuff tears
Motor-evoked potential (MEP) recruitment curves of the deltoideus muscle (DM), both sides averaged, at rest (a) and low-level muscular activity of the DM in slight voluntary abduction of the shoulder against resistance (b) in patients (filled circles) and control subjects (open circles) after transcranial magnetic stimulation (TMS) at five different stimulus levels. T individual resting motor threshold for first dorsal interosseus muscle (FDI); T+ increasing stimulus intensities given in percentage of the magnetic stimulator output (MSO)
