Diagnostic Value of the H Reflex Study in Low Back Pain Ueon Woo Rah Department of Medical Science The Graduate School, Yonsei University (Directed by Prof. Jung Soon Shin, M.D.) The subjects of this study were 16l cases with low back pain aged from 14 to 67 years who received electrodiagnostic examination including H reflex study at Severance Hospital during the period September 1, 1982 to August 31, 1983. The objectives of this study were to demonstrate the diagnostic value and the clinical usefulness in low back pain patients with unilateral radiculopathy over the lumbosacral area. Forty normal subjects aged from 18 to 49 years served as controls for this study. The mean difference in the H reflex latency of both legs of 40 normal subjects was as little as 0.14Β±0.15 msec and it was statistically non significant(p<0.05) .The standard error inherent in predicting the H reflex latency in one leg from that in the other in the same subject was 0.30msec. One hundred and sixty-one cases with low back pain were divided into 3 groups which consisted of L5 radiculopathy, Sl radiculopathy and normal EMG groups. These groups of 66, 45 and 50 patients respectively were matched for age, sex and the level of root involvement. H reflex latency were measured in both legs. The mean difference of each group was 0.12Β±0.12 msec, 1.93Β±1.98 msec and 0.31Β±0.48 msec respectively. So the mean difference of Sl radiculopathy group was significantly prolonged. Therefore in patients with S1 radiculopathy a men difference of more than 1.0 msec would indicate an abnormality. The H reflex was present but prolonged in latency as compared to the unaffected side in 23 cases, it was absent in the affected side in 17 cases and the sum was 40 cases among 45 cases with unilateral Sl radiculopathy confirmed by EMG examination . Five cases with normal EMG finding had abnormal result of H reflex study. So the H reflex study was an diagnostic aid in unilateral Sl radiculopathy in addition to traditional EMG study. H reflex study was an objective test that can be of great diagnostic help in cases in which there was suspicion of Sl radiculopathy but normal EMG finding. In conclusion, the H reflex study can be easily done all EMG laboratories and so it will increase the chance for accuracy in the diagnosis of radiculopathy or in the determination of the level of the lesion.restrictio

[영문]Anti-neural antibodies have been implicated in the pathogenesis of nerve damage in patients with Guillain-Barre syndrome, leprosy, and other motor neuron diseases. Considering exposure of damaged nerve tissue to the immune system during traumatic injuries, the resulting anti-neural antibodies formed in patients with nervous system injury may affect the healing process of nerve tissues or induce nerve damage at the injury sites or other sites. To date, however, no information is available on the prevalence of anti-neural antibodies in sera from patients with traumatic nervous system injury and controls. In this study, serum samples were obtained from 185 patients with traumatic nervous system injury and 291 controls and antibodies were detected by an enzyme linked-immunosorbent assay(ELISA) against ceramide, asialo-GM^^1 (AGM^^1 ), and galactocerebroside(GC). The results were then analyzed based on nerve injury sites, severity, and presence or absence of associated injuries, duration after injury, etc. The results obtained were as follows: 1 The major immununoglobulin class was IgM against the ceramide, GC, and AGM^^1 antigens in sera from patients with traumatic nervous system injury. 2. Among 185 patients with traumatic nervous system injury, a significant level of antibodies were detectable in 75(40.5%) against ceramide, in 71(38.4%) against AGM^^1 , and in 57(37.8%) against GC antigen, respectively. In contrast, of 291 serum specimens from controls, 55(18.9%) were reactive with ceramide, 43(14.8%) with AGM^^1 , and 38(13.0%) with GC, respectively. The seroprevalence of anti-neural antibodies was thus significantly higher among patients with traumatic nervous system injury than among controls (p<0.01). 3. There was no significant difference of the prevalence rate and the mean value of anti-neural antibodies among three patient groups, one with head injury, a second with spinal cord injury, and a third, amputation. However serum antibody reactivity was higher in the severe head injury and incomplete spinal cord injury sub-groups than in those who suffered from other associated injuries. 4. The value of anti-neural IgM antibodies gradually decreased in most patients with traumatic nervous system injury within two to three months after trauma. In about six to ten months after injury, the value of IgM antibodies significantly decreased below the normal values of these antibodies. This study thus showed that patients with traumatic nervous system injury had a significant level of circulating anti-neural IgM antibodies. But any immediate adversary effect of such anti-bodies to the patients was net expected considering the relatively short life of anti-neural antibodies. However, further fellow-up studies on these patients are desirable to understand the role of anti-neural antibodies in the pathogenesis of nerve damage.prohibitio
