Purpose of the Study

To find out the influence of disc herniation at L5-S1 level on, H-reflex latency and H/M ratio. Apparatus Used:Electrodiagnosis machine, Plinth, Measuring tape, ECGgel.

Methodology

It is experimental study of same subject design. The study was conducted with 18 patients with disc herniation presented with unilateral radiating pain having positive SLR between age group of 20-50 yrs.

Procedure

H-reflex recording was performed on subjects after positioning of the patient and electrodes, recording was done after a submaximal stimulus was given for H-reflex to posterior tibial nerve of affected and unaffected leg respectively.

Result

Paired t-test was used for data analysis, which showed significant changes in H -latency (p<.05) and H/M ratio(p<.05) on affected side.

Conclusion

This study concluded that there are significant changes in H latency and H/M ratio on affected side. Hence H-reflex latency and H/M ratio can be used as diagnostic tool in L5- S1 level disc herniation.
