“…This coupling is in accordance with previous reports of neurophysiologic mechanisms mediating respiratorymotor interactions. For instance, resistive loaded inspiration significantly enhanced tonic vibratory response in the extensor digitorum (Balzamo et al 1997), but did not affect contraction of biceps brachialis (Fontanari et al 1996). The latency of median nerve components of somatosensory evoked potentials (SEPs) was lengthened by inspiratory, but not by expiratory, resistive loaded breathing, suggesting possible inhibitory effects of forceful inspiration on the wrist/finger flexors (Balzamo et al 1999).…”

Li S, Rymer WZ. Voluntary breathing influences corticospinal excitability of nonrespiratory finger muscles. J Neurophysiol 105: 512-521, 2011. First published December 15, 2010 doi:10.1152/jn.00946.2010. The present study aimed to investigate neurophysiologic mechanisms mediating the newly discovered phenomenon of respiratory-motor interactions and to explore its potential clinical application for motor recovery. First, young and healthy subjects were instructed to breathe normally (NORM); to exhale (OUT) or inhale (IN) as fast as possible in a self-paced manner; or to voluntarily hold breath (HOLD). In experiment 1 (n ϭ 14), transcranial magnetic stimulation (TMS) was applied during 10% maximal voluntary contraction (MVC) finger flexion force production or at rest. The motor-evoked potentials (MEPs) were recorded from flexor digitorum superficialis (FDS), extensor digitorum communis (EDC), and abductor digiti minimi (ADM) muscles. Similarly, in experiment 2 (n ϭ 11), electrical stimulation (ES) was applied to FDS or EDC during the described four breathing conditions while subjects maintained 10%MVC of finger flexion or extension and at rest. In the exploratory clinical experiments (experiment 3), four patients with chronic neurological disorders (three strokes, one traumatic brain injury) received a 30-min session of breathing-controlled ES to the impaired EDC. In experiment 1, the EDC MEP magnitudes increased significantly during IN and OUT at both 10%MVC and rest; the FDS MEPs were enhanced only at 10%MVC, whereas the ADM MEP increased only during OUT, compared with NORM for both at rest and 10%MVC. No difference was found between NORM and HOLD for all three muscles. In experiment 2, when FDS was stimulated, force response was enhanced during both IN and OUT, but only at 10%MVC. When EDC was stimulated, force response increased at both 10%MVC and rest, only during IN, but not OUT. The averaged response latency was 83 ms for the finger extensors and 79 ms for the finger flexors. After a 30-min intervention of ES to EDC triggered by forced inspiration in experiment 3, we observed a significant reduction in finger flexor spasticity. The spasticity reduction lasted for Ն4 wk in all four patients. TMS and ES data, collectively, support the phenomenon that there is an overall respiration-related enhancement on the motor system, with a strong inspiration-finger extension coupling during voluntary breathing. As such, breathing-controlled electrical stimulation (i.e., stimulation to finger extensors delivered during the voluntary inspiratory phase) could be applied for enhancing finger extension strength and finger flexor spasticity reduction in poststroke patients.

“…In contrast, a previous study demonstrated that VL tonic vibratory reflex at rest was increased by inspiratory resistive load and decreased by expiratory resistive load (Balzamo et al, 1997). In addition, it has been shown that recruitment of high-frequency motor units in the VL during voluntary isometric contractions sustained at 80% of maximal force was not modified by inspiratory loading but was reduced by expiratory loading (Fontanari et al, 1996). Based on data that had been obtained in animal experiments (Deshpande and Devanandan, 1970;Schiemann and Schomburg, 1972), they (Balzamo et al, 1997;Fontanari et al, 1996) postulated a mechanism by which motor drive to leg muscles was inhibited by activation of pulmonary vagal afferents during the expiratory phase.…”

Furthermore, a recent study (Hudson et al 2012) has suggested that activations of pulmonary and non-pulmonary respiratory afferents associated with increases in lung volume augmented excitability of the corticospinal pathway to scalene muscles during both voluntary inspiration and expiration.…”

“…On the other hand, OLV causes hyperinfl ation of the ventilated lung [7,8]. It has been shown that when the lung is hyperinfl ated, the pulmonary vagal afferent nerves are stimulated [3][4][5][6], which induces an increase in the activity of the skeletal muscles [3][4][5][6]. Consequently, both defl ation and hyperinfl ation of the lung are thought to strengthen the contraction of the skeletal muscles.…”
