Stroke is the leading cause of adult disability throughout the world. Motor function deficit is one of the common consequences. It is usually described for the peripheral muscles that there is a cortical representation contralaterale with a crossed cortico-spinal route: the consequence is a contralaterale motor disorder on the brain damage. The impact of a stroke on diaphragm movements have been described in 6 studies: however, they were all observational and transversal studies evaluating diaphragm function. Assessment using diaphragm thickness is another technique described in the literature. Visualization of diaphragm in the zone of apposition allows to assess diaphragm thickness at inspiration and expiration. The impact of a stroke on diaphragm thickening has been reported in only one recent observational study. It seems that diaphragm would be damaged after a stroke, but unilateral or bilateral dysfonction is yet to be confirmed. Moreover, only a few measurements were performed in these studies, and not a diaphragm function follow-up.
This clinical trial is being conducted to study lung function and movement of the major muscle involved in breathing (the diaphragm) after a brachial plexus nerve block (nerve "freezing"). The purpose of this study is to find out what effects (good and bad) ultrasound guided nerve freezing has on the movement of the patient's diaphragm and their lung function. The potential advantage of ultrasound guidance will be a lesser chance of freezing the nerves that innervate the diaphragm and thus having less of an effect on lung function.
