Respiratory responses to stimulation of abdominal and upper-thorax intercostal muscles using multiple Permaloc® electrodes

James S. Walter, PhD, et al.

Electrical stimulation of the diaphragm is an important method of respiratory management following spinal cord injury (SCI) in the neck; however, this method is limited by accessory abdominal and upper-chest muscle paralysis. We tested a 12-channel stimulator and surface and intramuscular electrodes in anesthetized dogs. Abdominal muscle stimulation induced large expiratory volumes, and upper-chest stimulation induced large inspiratory volumes. Combined muscle stimulation increased tidal volumes important for respiration and increased expiratory flow rates important for cough. Current methods of accessory muscle stimulation need to be studied further to improve SCI respiratory management, particularly together with diaphragmatic pacing.
