Abstract
|
|
|
Electromyographic and Nerve Conduction Studies were carried out in 23 hemiplegic patients, 19 men and 4 women, for ?evidence of ´lower motor neuron involvement.
Patients ranged from 5 to 63 years in age and the majority had hemiplegia or hemiparesis secondary to cerebrovascular accident. 13 patients were right and 10 were left hemiplegia.
Careful histories were taken and examination made in an attempt to rule out all possible causes of peripheral nerve involvement resulting from diabetes mellitus, alcoholism, malnutrition or trauma.
The nerve conduction velocities in ulnar and peroneal nerves bilaterally in 17 hemiplegic
patients with relation to skin temperature and calf circumference were studied.
Using concentric needle electrodes, electromyographic study was performed on the affected
limbs in 23 hemiplegic patients.
The results obtained were summarized as follows.
1. Motor and sensory nerve conduction velocities in ulnar and peroneal nerves bilaterally in hemiplegic patients revealed a statisticallyy significant slowing in the affected limbs compared with the normal limbs, but within normal limit.
2. Skin temperature of affected limb in both upper and lower, and calf circumference of
affected limb were significantly lower than that of normal limb in hemiplegia.
3. Correlation between a low :skin temperature and decreased motor nerve conduction velocity
in the affected limb was found.
4. On EMG examination of affected upper limb, fibrillation potentials and positive sharp waves were found in 30.43% of hemiplegia and 85.71 % of them had duration of 1 month to 6 months.
