Our aim was to electrically activate small diameter parasympathetic fibres in the sacral anterior roots, without activating the larger somatic fibres to the external anal sphincter (EAS). Electrodes were implanted on selected roots in five adult dogs

Electrical stimulation of the phrenic nerve motor point of the diaphragm through laparoscopic implantation of a pacing system is an option for high spinal cord–injured patients with chronic respiratory insufficiency. This study assesses the operati

Laparoscopic mapping of the phrenic nerve motor points using test stimulation was conducted for the implant of epimysial electrodes for diaphragm pacing in dogs. Both visual assessment of muscle activation and measurements of recruitment were useful

A method has been developed to activate separately and alternately two axon groups in an intact nerve trunk through a single-channel stimulation electrode. Two types of stimuli, quasitrapezoidal-shaped and narrow rectangular-shaped current pulses, we

Impedance pneumography signals were characterised during diaphragm pacing using stimulating and recording electrodes placed on the abdominal surface of the diaphragm. These measurements were useful for the detection of muscle contraction without conf

Intramuscular electrodes are currently in use for clinically implementing several electrotherapeutic and neuroprosthetic protocols. A decrease in motor recruitment is often reported in these systems due to movement of the electrode tip from the initi

Laparoscopic stapling was found to be a viable option for attaching epimysial electrodes onto the abdominal surface of the diaphragm. Stapling was preferable to suturing due to its simplicity and speed.Of the two staplers tested in this study, the Et

The underlying cause of electrical stimulation-induced tissue trauma is debated. Our focus has been to study effects of generating electrochemical by-products at the electrode-electrolyte interface, using the pulse-clamp technique coupled with voltam
