title: Needle electromyographic evaluation of the diaphragm.
abstract: Needle electromyography of the diaphragm is a useful tool in diagnosis and prognosis of patients with diaphragmatic dysfunction. Spontaneous activity, polyphasic motor units and decreased recruitment can be found in phrenic nerve and spinal cord injury. We describe a safe technique for studying the diaphragm using needle electrodes.
