On EMG examination, there was increased insertional activity and the presence of abnormal spontaneous electrical activity at rest in the left 1st DI and ADM with a 50% reduction in interference patterns during maximum voluntary contraction in both of these muscles.
On EMG examination, there was increased insertional activity and the presence of abnormal spontaneous electrical activity at rest in the right 1st Dl, ADM, and FCU, with a 75% reduction in interference patterns during maximum voluntary contraction in the right 1st DI and ADM.
Compared with the diaphragm and the intercostal and paraspinal muscles, RA displays several advantages for EMG examination
Needle EMG examination revealed a small amount of denervation potentials in APB and ADM also motor unit rarefaction, increase of polyphasic motor unit potantials (MUP) and chronic neurogenic changes in APB, ADM and EIP muscles, whereas needle EMG findings of the biceps and triceps were normal (Table 2).
4) reported 4-5 cases/year out of 3500 EMG examinations.
No denervation activity was detected by needle EMG examination of the abductor pollicis brevis muscles in both hands.
Concentric needle EMG examination of the proximal and distal muscles of the arms, other than the abductor pollicis brevis muscles, and the muscles of the legs were normal excluding the possibility of a brachial plexitis, radiculitis, or polyneuritis.
Both CTS classification systems identified bilateral median motor and sensory involvement with a demyelinating neuropathic process, but only the GEHS classification system demonstrated electrophysiological evidence of motor fiber axonopathy in the bilateral APBs by EMG examination
of the upper segment of the trapezius muscle revealed reduced recruitment of motor units, increased polyphasia, and occurrence of mild PSWs and fibrillation potentials.
