Clinical Comparative Research on Before and After Treatment of Spinal Cord Injuries

Objective In order to study the value and effective of CWM in therapeutic Spinal cord injuries that can be judged by somatosensory evoked potentials in neurological function. Methods 90 cases of SCI patients therapeuticed by MEP examination with a May-2 magnetic stimulator, MEP were recorded bilaterally at abductor pollicis brevis and anterior tibialis muscles. F waves and M waves were also recorded to calculated the central motor conductive time, SEP examination was performed with a key point electromyograh. Results In SCI group the latency and amplitude of the APB MEP were （29.12 ±13.69）mS and （0.36 ±0.34）mv respectively, the latency and amplitude of the AT MEP were （41.58 ± 15.87）ms and （0.45 ±0.73）mv respectively. All of them were significantly different from the results of control group （P〈0.05）. Among them the complete paralysis cases had no MEP signals, while the MEP in incomplete injured group had decreased amplitude and increased latency. There was significant correlation between the MEP latency and the ASIA motor scores. There were significantly different after therapeutic , APB MEP were （24.31±13.40）ms and （0.69 ± 0.58）mv. When it comes to clinical effective, there were 44patients recovered, 38patients recovered more or less , 9 patients no effects. Conclusion The muscle strength under the injured level is intensively correlated with the MEP abnormal. MEP examination can provide an objective and quantitative standard for judging the motor functional status in the cord. While the SEP examination can not reflect the the severity of motor lesion. The methods of CWM is an effectively one to therapeutic SCI , and take it the earlier the better.
