COUGH ATTACKS ELICITED by movement of the neck and right arm are repor
ted in a patient who had sustained several shoulder injuries and who h
ad an anterior scalenectomy. The coughing was accompanied by weakness
in the right upper limb. At exploration, the phrenic nerve was found a
dhered to the brachial plexus. The cough attacks disappeared, and the
weakness of the right upper limb improved somewhat after lysis of the
adhesions between the phrenic nerve and the plexus and after external
neurolysis of the upper, middle, and lower trunks. Postoperatively, th
e patient could elevate his right arm without coughing.
