Effects of inspiratory loading on the abductor pollicis brevis EMG response to transcranial magnetic stimulation. Effect of breathing against inspiratory linear resistive loads on the latency (top) and the amplitude (bottom) of the electromyographic responses of the abductor pollicis brevis to magnetic transcranial stimulations (TMS) delivered during inspiration (left) or expiration (right). R0, R5 and R20 correspond to breathingagainst no resistance, against a resistance of 5 cmH₂O/L/s, andagainst a resistance of 20 cmH₂O/L/s, respectively. Vertical barscorrespond to mean values with indication of ± 1 SD. No significant differences were found between conditions.
