Abstract
Objective:
To observe the changes of H reflex and it’s different parameters in patients of chronic low back pain (clinically diagnosed as radiculopthy.) and to correlate the findings with MRI.
Method:
It was an observational cross-sectional study on 51 patients with clinical diagnosis of lumbosacral radiculopathy. First H-reflex study was done . Then findings were statistically analysed and correlated with their radiological counterpart.
Result:
Abnormal H-Reflex has the maximum percent prevalence (92%) followed by H amplitude (88%); even more than percent prevalence of abnormal MRI (65%).
Regarding the correlation with MRI, unilaterally absent H reflex showed extremely statistically significant correlation (P=0.0004).
Apart from it, H reflex as a whole, H amplitude, H latency, bilaterally absent H reflex had statistically significant correlation with MRI (P<0.05).
Conclusion:
Nerve conduction studies, specially H reflex with its individual parameters can be used as efficient diagnostic tool for lumbosacral radiculopathy. It is evidenced by high percent prevalence of abnormal results of the above parameters as well as significant correlation (by P value) and agreement (by Kappa coefficient) studies.
